Executive Summary
This representation has been prepared by Savills (UK) Limited on behalf of a local housebuilder consortium, hereafter known as
“the Consortium”. It is made in respect of Guildford Borough Council’s (GBC) emerging Preliminary Draft Charging Schedule
(PDCS) for the Community Infrastructure Levy (CIL).
The CIL Guidance contained within the Planning Practice Guidance (PPG) is clear on the narrow focus of the CIL Examination
process permitted by the Regulations:
The Statutory CIL Guidance is clear on the narrow focus of the CIL Examination process permitted by the Regulations: -
“The Examiner should establish that:
The charging authority has complied with the required procedures set out in Part 11 of the Planning Act 2008
and the CIL Regulations;
The charging authority’s draft charging schedule is supported by background documents containing
appropriate available evidence;
The proposed rate or rates are informed by and consistent with, the evidence on economic viability across
the charging authority’s area; and
Evidence has been provided that shows the proposed rate (or rates) would not threaten delivery of the
relevant Plan as a whole.”1
This representation explores whether GBC has presented appropriate, available evidence, made reasonable conclusions and is
able to demonstrate that it “strikes an appropriate balance” in accordance with Regulation 12(1) of the CIL Regulations, when
formulating their proposed PDCS rates.
The Consortium has fundamental concerns with the approach taken by GBC in proposing its rates, notably:
Unviable Rates - The current proposed CIL rates are unviable and risk rendering a significant proportion of the housing
supply across the District undeliverable;
Incorrect Assumptions - A number of the key viability inputs adopted by PBA are incorrect. Specifically, the allowance
for Section 106 contributions is insufficient with a number of the other costs out of date, This results in an over-estimation
of the maximum CIL rates that can be supported;

Consortium of House Builders February 2014 2
Risks for delivery of Strategic Sites – The appraisals relating to the large, strategic residential sites do not take into
account the significant ‘opening up’ and abnormal costs for the delivery of sites of this scale. We would strongly recommend
that the Council considers applying a zero rate for their strategic residential development sites, especially given the stage of
the Local Plan process.
Alternative Viability Appraisals – We have undertaken alternative viability appraisals looking at the impact of Section 106
obligations, profit margin, and abnormal allowances on the level of CIL that can be supported.
Whether the proposed rates of CIL and evidence are updated to reflect the recent amendments to the PPG with respect to
the recommended threshold restricting affordable housing and S106 being sought for schemes of 10 or less units.
We have subsequently prepared the following representation, which can be split up as follows:
Section 1.0 - provides an introduction to the representation;
Section 2.0 - provides an overview of the planning and legal background in the Borough;
Section 3.0 - outlines specific points about the available evidence bases;
Section 4.0 - provides scrutiny of the available viability evidence (PBA, December 2014);
Section 5.0 - outlines the position of the Consortium in respect of the effective operation of CIL;
Section 6.0 - provides conclusions.
Where relevant this representation provides comment on the supporting evidence / existing guidance and also makes reference
to policy documents, a list of which can be found at Appendix 1. Savills has submitted a separate representation on behalf of
Wisley Property Investments Ltd, specific to the ongoing land promotion coordinated by Savills on land at the former Wisley
Airfield.

1. Introduction
1.1 This representation has been prepared by Savills (UK) Limited, hereafter known as “Savills”, in respect of Guildford
Borough Council’s Preliminary Draft Charging Schedule consultation, on behalf of the following (in alphabetical order):
Countryside Properties
Crest Nicholson
Taylor Wimpey
1.2 Hereafter referred to as the ‘Consortium’.
1.3 The Consortium controls significant land interests within Guildford Borough, which include consented residential
development and sites promoted in the emerging Local Plan. The land interests play an important part in the delivery of
Guildford’s growth aspirations and housing land supply. The rate of CIL is therefore of critical importance to the
Consortium.
1.4 This representation has been submitted to influence the emerging Community Infrastructure Levy (CIL) Preliminary
Draft Charging Schedule (PDCS) and our comments relate to the proposed rates for residential development.
1.5 The Consortium has concerns. In particular, with the assumptions and allowances that have been made within the
Viability Study produced by Peter Brett Associates (December 2014) which we understand GBC has used to formulate
their proposed PDCS rates. The lack of any Section 106 contributions within the appraisals is particularly concerning
With the reason given for this that at this stage the Council believe specific infrastructure requirements are unknown.
Yet Appendix B of the GBC Draft Local Plan (July 2014) contains an Infrastructure Schedule. This Schedule sets out
the infrastructure needed to support the strategic sites.
1.6 Savills has submitted a separate representation on behalf of Wisley Property Investments Ltd, specific to the ongoing
land promotion coordinated by Savills on land at the former Wisley Airfield.
Savills Research
1.7 Savills in January 2014 published research that assessed the impact of CIL on development viability2 (see Appendix
2). The research focused on the level of CIL balanced against affordable housing provision and demonstrated that
there is a trade off required to enable a deliverable five year housing land supply. The key finding of the report is that
“for local planning policies to be viable, there is a three way trade-off between the costs of CIL, Section 106 funding of
infrastructure and affordable housing policy, with the costs of local standards and the move to zero carbon being
additional costs to be factored into the trade-off” (emphasis added).
1.8 The research notes that the ability of an area to afford CIL largely depends on the strength of its housing market.
Where the housing market is stronger (higher £ per sq ft) the total “pot” available for these contributions is higher. In
contrast, lower value areas see reduced viability and subsequently a reduced “pot”. It therefore becomes a question for
local authorities to consider the appropriate trade-off.

1.9 A high CIL rate, together with high site mitigation and affordable housing requirements will put a strain on the viability
of development and hence the five year housing land supply.
1.10 The PDCS sets different rates for different locations of development, strategic scale residential development has a
proposed rate of £400 per sqm, except the Slyfield site that has a rate of £150 per sqm. It is worth noting that over 40
Local Authorities have taken a pragmatic approach to CIL, choosing to set a £0 per sqm CIL rate for their strategic
sites. These authorities therefore recognise that the delivery of these sites is vitally important and should be enabled
via Section 106.
1.11 Guildford Borough consulted on their Draft Local Plan Strategy and Sites July to September 2014. This contained
Guildford Borough’s preferred strategy, which is largely reliant on greenfield sites (73% of the total supply in the first
five years). The sites identified within the preferred strategy largely are coming from development adjoining
settlements, strategic urban extensions and a new settlement. By way of example, the three strategic sites (Wisley
airfield, Gosden Hill and Blackwell farm) will deliver 6,350 dwellings (51% of the total supply over the 20 year plan
period).
1.12 It is evident that there will be significant reliance on the delivery of greenfield sites and the emerging strategic
allocations. It is therefore crucial that the developers’ interest and subsequent delivery of sites must not be
compromised by the introduction of an unviable level of CIL.
1.13 In addition, the National Planning Policy Framework (NPPF) requires Councils to boost significantly the supply of
housing, and identify annually a supply of housing sufficient to provide five years worth of housing against their housing
requirements3. The on-going delivery of housing is therefore required and it is important that the proposed CIL rate
does not harm the viability of achieving a rolling supply of housing; which is particularly important in the absence of an
up to date Local Plan.
1.14 It is the case that Guildford Borough only have 1.1 years of housing land supply. GBC have acknowledged that there
is a significant housing shortfall (Annual Monitoring Report 2013/14, page 8) stating that “we are not currently able to
demonstrate a five year supply of deliverable housing land without amendments to the Green Belt boundaries and use
of countryside land”. Furthermore GBC have failed to meet their housing targets over the period in six out of the last
eight years, which has led to an undersupply of 1,563 units.
1.15 These aspects demonstrate the importance of a CIL rate that does not further restrict housing delivery in an authority
area that is already struggling to provide housing.
Purpose
1.16 The following representation is made in the context of the Community Infrastructure Levy (Amendment) Regulations
2014 and relevant guidance (which was added to the national Planning Practice Guidance in June 2014).
1.17 The desirability of funding from CIL is a key test of the Regulations. The purpose of CIL is to facilitate the delivery of
development, including new housing to meet the key NPPF objective for a significant boost in the supply of
3 Paragraph 47, NPPF
Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 5
housing. This NPPF objective provides perspective on how desirable CIL funding may or may not be, in relation to the
range of legal and planning mechanisms available to secure infrastructure delivery. There is no obligation on the
Council to pursue CIL by a certain date or to pursue it at all (particularly as existing mechanisms are available to
secure site mitigation costs).
1.18 The adoption of the CIL must be made in the context of the collective interest to deliver well planned, viable and
feasible development in order to meet the needs of the District. It must not jeopardise the objective for a significant
boost in the supply of housing. The plan for housing and infrastructure delivery in Guildford over the next 20 years has
not yet been finalised; the current Local Plan is out of date. The introduction of CIL at this stage, particularly at the
wrong rate, would have significant ramifications on the delivery of housing and future strategic sites.
1.19 In submitting this representation, the Consortium is only commenting on particular key areas of the evidence base.
Where this representation is silent on other parts to the evidence base this must not be taken as agreement with them
and the Consortium reserves the right to make further comments upon the evidence base at the subsequent stages, in
the event the Council pursues their current proposals.

2. Summary of National Policy and Legal Context
2.1 In respect of the preparation of Charging Schedules and support documentation, it is important to have regard to the
Government policy, guidance and law. This includes:
National Planning Policy Framework (NPPF)
Part 11 of the Planning Act 2008; Community Infrastructure Levy Regulations 2010 (as amended)
Planning Practice Guidance (PPG) CIL Guidance 2014 (as amended)
2.2 The Consortium’s comments are based on the above.
National Planning Policy Framework (NPPF)
2.3 It is important that the preparation of CIL is in the spirit of the NPPF, notably that it is delivery-focused and “positively
prepared”4.
2.4 The NPPF outlines 12 principles for both plan making and decision taking, notably that planning should “proactively
drive and support sustainable economic growth”5. Plan making should “take account of market signals such as land
prices and housing affordability” and that “the Government is committed to ensuring that the planning system does
everything it can to support sustainable economic growth”6.
2.5 Furthermore, the NPPF refers to the “cumulative impacts”7 of standards and policies relating to the economic impact
of these policies (such as affordable housing) and that these should not put the implementation of the Plan at serious
risk. Existing policy requirements should therefore be considered when assessing the impact of CIL on development
viability.
2.6 The NPPF calls for local authorities to boost significantly the supply of housing8. It requires local authorities to:
Meet the full, objectively assessed needs for housing, including identifying key sites;
Identify deliverable sites to provide five years worth of supply and developable sites further ahead;
Provide a housing trajectory for the plan period describing how the five year supply is to be maintained.

Consortium of House Builders February 2014 7
2.7 The NPPF expressly states that CIL “should be worked up and tested alongside the Local Plan” and “should
support and incentivise new development”9. To comply with this policy, CIL Charging Schedules must be
demonstrated to have positive effects on development and have regard to an up-to-date Local Plan. The absence of
adverse effects on the economic viability of development, whether serious or otherwise is not enough to justify CIL
proposals. Charging Authorities have a positive duty when it comes to setting CIL rates and formulating their approach
on the application of CIL.
Planning Act 2008 (as amended)
2.8 Section 205 (2) of Part 11 of the 2008 Act (as amended by the Localism Act 2011) states that:
“In making the regulations the Secretary of State shall aim to ensure that the overall purpose of CIL is to ensure that
costs incurred in supporting the development of an area can be funded wholly or partly by owners or developers of
land in a way that does not make development of the area economically unviable.”
2.9 Examiners are required in particular to have regard to the matters listed in Section 211(2) and 211(4). This requires
examiners to consider whether the relevant charging authority has had regard to the following matters:
Actual and expected costs of infrastructure;
Matters specific by the CIL Regulations relating to the economic viability of development;
Other actual and expected sources of funding for infrastructure; and
Actual or expected administrative expenses in connection with CIL.
2.10 Regulation 14 of the CIL Regulations (as amended) expands on these requirements, explaining that charging
authorities must, when striking an appropriate balance, have regard to:
The desirability of funding from CIL (in whole or in part), the actual and expected estimated total cost of
infrastructure required to support the development of its area, taking into account other actual and expected
sources of funding; and
The potential effects (taken as a whole) of the imposition of CIL on the economic viability of development across its
area.
2.11 The Examiner will need to determine whether appropriate evidence on infrastructure needs and development viability
has been presented by the Council.
Planning Practice Guidance (PPG)
2.12 Relevant to CIL, the PPG (2014) states:
Charging schedules should be consistent with, and support the implementation of, up-to-date relevant Plans10.
The need for balance (as per Regulation 1411); and
9 Ibid, Paragraph 175, March 2012
10 Paragraph 10, Reference ID: 25-010-20140612, PPG CIL Guidance 2014 11
CIL Regulations 2010 (as amended)
Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 8
The need for “appropriate available evidence to inform the Draft Charging Schedule” (as per Schedule 211(7)(a) of
the 2008 Act12.
2.13 The PPG reaffirms the requirement of paragraph 175 of the NPPF which states that, where practical, charging
schedules should be worked up and tested alongside the Local Plan. It also states that “a charging authority may use a
draft plan if they are proposing a joint examination of their relevant Plan and their levy charging schedule”13
.
2.14 The policy direction from central government is very much towards facilitating development. This policy imperative
should have a major material bearing on the CIL rates. This applies to the evidence to support the balance reached
between the desirability of funding infrastructure through CIL and the potential effects on economic viability of
development across that area.
2.15 The Guidance states that it is up to charging authorities to decide how much potential development they are willing to
put at risk through CIL (the “appropriate balance”). Clearly this judgement needs to consider the wider planning
priorities. Furthermore, the CIL Guidance outlines that CIL receipts are not expected to pay for all infrastructure but a
“significant contribution”14
. The overall approach and rate of CIL will have to pay attention to the development plan
and intended delivery.
2.16 The Guidance also states that charging authorities may adopt differential rates in relation to:
geographical zones within the charging authority’s boundary
types of development; and/or
scales of development15
.
2.17 It explains that where a particular type or scale of development has low, very low or zero viability, the charging
authority should consider setting low or zero rates for that type of development.
Recent relevant changes to the PPG
2.18 On 28th
November 2014, the PPG was updated to include the recent content of the ministerial statement by Brandon
Lewis about the minimum thresholds required to trigger the need for affordable housing and tariff based contributions.
The Government position is that contributions for affordable housing and tariff style planning obligations should not be
sought from developments of 10-units or less. In rural areas Local Authorities may choose to apply a lower threshold of
5-units or less.
2.19 This guidance must be reflected in GBC’s viability appraisals.

3. Planning and Infrastructure Delivery
The Development Plan
3.1 The Development Plan for Guildford includes the Guildford Borough Local Plan adopted in 2003. The Council does not
have an up-to-date development plan.
3.2 Guildford Borough recently consulted on their Draft Local Plan Strategy and Sites document (dated July 2014). This
document sets out the Borough’s preferred strategy on housing and includes a number of draft allocations to meet the
housing target. Guildford have since said that they will reassess the Local Plan (November 2014).
3.3 The Consortium questions how the Council can be certain about the infrastructure requirements of the District without a
well advanced or adopted Local Plan. This is demonstrated by the failure of PBA to include any Section 106 costs
within any appraisals on the basis of there being unknown infrastructure requirements. The Council will need to
demonstrate at the CIL Examination that it has had full regard to actual and expected costs of infrastructure to support
delivery to meet the housing needs; and pertinently would not render the supply of development unviable to achieve its
rolling five year supply, as required by the NPPF. At such an uncertain stage in the preparation of the emerging plan it
is unclear how this can be achieved.
Housing Delivery
3.4 Guildford’s Local Plan policy H1, which sets out the housing provision over the plan period, was not ‘saved’ and as a
result when the South East Plan was revoked on the 25 March 2015, GBC no longer had an ‘up to date’ policy setting
out their housing provision. In addition to this, the Borough successfully challenged the South East Plan requirement in
the High Court in 2010, which quashed that aspect of the South East Plan.
3.5 Local Planning Authorities are required to boost their supply of housing (NPPF, paragraph 47). Given that Guildford’s
Local Plan is out of date and there is no ‘saved’ policies in place that address development needs beyond 2006, GBC
have a significant housing shortfall.
3.6 The housing target is included within the draft Local Plan (652 dwellings per annum). The latest AMR (June 2014) and
the accompanying Housing Topic Paper (July 2014) acknowledge that the Borough is currently unable to demonstrate
a five year supply of deliverable sites. In addition, both of these documents recognise the significant under supply of
housing which has accumulated over the last eight years.
3.7 Savills have undertaken their own assessment of GBC’s five year supply, it concludes that there is 1.1 years of supply
when SHLAA sites are excluded (73% of the SHLAA sites are Green Belt sites, the majority of which are unlikely to
come forward in the short term particularly when the Local Plan has stalled). The supply rises to 3.6 years when
SHLAA sites are included. It is also apparent that the District is an area of persistent under-delivery, where the 20%
buffer is applied to the five year supply calculations in accordance with the NPPF.
3.8 It is therefore important that the requirements and implications of CIL are assessed in this context. The Consortium is
of the view that pursuing a charging schedule now is premature for the following reasons:
Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 10
Guildford does not have an up-to-date local plan and work has paused on the emerging Local Plan
The District is an area of persistent under-delivery and is likely to require a significant number of dwellings brought
forward over the future plan period.
Certainty over the infrastructure needs to support future growth is required, but it is not possible at this stage as
confirmed by the PBA Local Plan Viability & Affordable Housing Study.
3.9 Should a schedule be advanced, then Section 106 costs should be incorporated into the appraisals and an additional
viability buffer must be applied to the appraisals, to reflect the uncertainty over plan production. The CIL rate should
be set at the level to enable the majority of schemes to come forward. It is relevant to note that the Borough places
priority on the delivery of previously developed sites, in Guildford town for example. This is in order to minimise the
loss of Green Belt land. The rate of CIL within Guildford is of particular relevance.
Strategic Sites
3.10 There is little acknowledgement throughout the supporting literature of the PDCS that Greenfield residential sites will
inevitability have higher upfront mitigation / infrastructure costs, making such development unviable.
3.11 Within the accompanying PBA Appraisals it appears that it has been assumed that only if the site is brownfield there
will be abnormal costs, yet Savills’ view is that abnormals should be incorporated within all the appraisals. The level
of average abnormal costs might not be the same on brownfield and greenfield sites generally, but on the
development on any sites there are likely to be unexpected issues.
3.12 With regards to opening up costs, the PBA Viability Report notes that on greenfield sites an allowance should be
made for opening up costs in terms of utilities, land preparation, SuDs and spine roads. Savills agree with PBA in that
it is likely that these costs will increase as schemes get bigger. However some of PBA’s other assumptions are
contested. The appraisals do not include opening up costs on any sites less than 50 units, yet these sites will still be
subject to some opening up costs, particularly if these sites are urban infill.
3.13 The PBA Local Plan Viability and Affordable Housing Study states that for 501 or more units the opening up costs
would be assumed at £20,000 per unit. Yet within the PBA Appraisals the opening up costs for the large strategic
sites vary significantly, but it is unclear what the reasons are for this. For instance the three emerging strategic sites
with a proposed rate of £400 per sqm (Wisley airfield, Gosden Hill and Blackwell Farm) are all for approximately
2,000 units and the PBA Viability Appraisals apply the assumed rate of £20,000 per unit. However the opening up
costs for Slyfield do not apply the assumed rate but instead apply a rate nearly four times that of the other sites
(£78,413 per unit) for a 1,000 unit scheme. There appears to be no justification for doing this in any of the supporting
text.
3.14 The three strategic sites of Wisley airfield, Gosden Hill and Blackwell Farm will contribute to 51% of the total
proposed housing supply of the plan period. The Council must recognise the importance of the delivery of these
types of sites to the housing supply. Other Councils have supported their rates with fine-grain viability work on
strategic sites, which establishes that such sites would be unable to support CIL in addition to policy compliant
affordable housing and large “site mitigation” Section 106 contributions. Without evidence to the contrary, the
conclusion that the bulk of housing will not come with significant on-site/site specific S106 requirements is not
accepted by the Consortium.
Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 11
3.15 Whilst the Council appear to have tested these three sites, the Consortium have concerns over a number of the inputs
within the appraisals, particularly with the lack of inclusion of specific infrastructure information within any of the
appraisals (apart from Slyfield). These concerns are fully detailed in Section 4.
3.16 The Council’s position in this regard is incongruous with the current status of the development plan; which is out-of-
date and without a robust housing strategy; and a significant shortfall in housing land supply.
3.17 The Consortium recommends that the PDCS is not progressed until such time when the emerging Local Plan is at an
appropriate stage of preparation and where an examination is possible. The Council would then be in accordance with
PPG CIL Guidance which states “A charging authority may use a draft plan if they are proposing a joint examination of
their relevant Plan and their levy charging schedule”.
CIL/Section 106 Relationship
3.18 The Draft Guildford Borough Infrastructure/Regulation 123 List identifies that to ensure that there is no duplication
between CIL and infrastructure they will not accept a planning obligation for any infrastructure included on the
Regulation 123 List (the ‘relevant infrastructure’ list). The draft 123 List does not list any specific projects, it is very
general in its approach. For instance under each of the categories excluded from the list is improvements directly
related to a development. This approach will mean that on strategic sites in particular, the level of Section 106 costs
are not likely to be massively different to what they are now. Until such a time that the Regulation 123 List is more
defined, an assumption must be made in the viability appraisals for similar levels of Section 106 that have previously
been agreed.
3.19 The Council recognise that on larger sites it is likely that substantial infrastructure requirements will continue to be
considered through S10616
. Yet these costs have not been factored into the appraisals. The reason given by PBA is
that specific infrastructure requirements are unknown. The Consortium are extremely concerned with the lack of any
S106 costs within the appraisals. Savills’ have undertaken their own appraisals (in Section 4 of this report), recent
planning permissions have been reviewed to ensure that an appropriate level of S106 is included. The review showed
that current S106 costs per dwelling ranged from between £7,000 (68 units, planning reference 13/P/01829) to
approximately £20,000 (400 units, planning reference 12/P/01973).
3.20 The PBA Local Plan Viability & Affordable Housing states that “for the majority of smaller sites (under 10 dwellings) are
likely to be met through off site delivery of infrastructure such as schools expansions, open space enhancements,
SANGS or transport improvements”. Savills do not contest this view, however these sites do not make a significant
contribution to the land supply over the plan period. The vast majority will be delivered through larger sites.
3.21 The Consortium is concerned about the lack of clarity about how the CIL/S106 relationship will be taken forward. This
creates confusion within the process and introduces the potential for “double dipping”.

Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 12
Council’s approach to SANG
3.22 The Council is proposing that mitigation for the Thames Basin Heath SPA will be sought through CIL. Both PDCS and
draft Local Plan (policy 17) identify that GBC will prioritise CIL spending to provide Suitable Available Natural Green
Space (SANG). GBC confirm that this priority for SANG will be formalised in the new Local Plan and in the Regulation
123 List17
. It is though the case that the emerging strategic sites will provide their own SANGs on-site, and hence
secured as relevant 'site specific' infrastructure.
3.23 The PDCS also identifies that Strategic Access Management and Maintenance (SAMM) will continue to be secured
through planning obligations18
.
Affordable housing/S106: 10 or less unit schemes threshold
3.24 The effect of this recent Government guidance on small scale typologies is worthy of consideration. Whilst, the likely
CIL rate may increase (as no affordable housing would be secured), the Consortium is keen that the “fair share”
principle applies for CIL, and that adequate funding is obtained for all sources to deliver the infrastructure needed.
3.25 The CIL Regulations clearly permit the differentiation of CIL rates by scale.

4. Viability Appraisal
4.1 Section 211 (7a) of the Planning Act 2008 (as amended), requires Councils to use “appropriate available evidence”
to inform their Charging Schedules. In the case of the PDCS, we have assumed that GBC have relied upon the
Guildford Borough Council Local Plan Viability & Affordable Housing Study (Final Report) prepared by PBA 19
produced
by PBA as their ‘appropriate available evidence’. We have critically examined this report as part of this representation
to determine if the Council has sufficiently met the requirements of Section 211 (7a) in proposing their rates.
4.2 The fundamental premise is that to enable delivery, sites must achieve a competitive land value for the landowner and
provide developers the required return on investment; otherwise development will be stifled. This is recognised by the
NPPF20
and is ‘in-built’ within the CIL 2010 Regulations (as amended). It is also the basis of the definition of viability
within the Harman Report.21
4.3 Owing to the key test of Regulation 14(1)22
it is important that the viability appraisals prepared are fit for purpose, as it
is clear that at Examination the Charging Schedules will need to be supported by “relevant evidence”23
. Within the CIL
2010 Regulations (as amended), LPAs must strike an appropriate balance and justify that balance with evidence at the
Examination, showing and explaining how the rates will contribute towards the implementation of their relevant Plan.24
The PBA Viability Assessment
4.4 We have reviewed the viability evidence prepared by PBA and split our response in respect of the viability work in to
the following:
Part 1 - outlines the areas that the Consortium has concerns over and justification for any differences.
Part 2 - includes our revised appraisals taking the points discussed in Part 1 in to account.
Part 1 – Areas of Concern
“Up-to-date” Evidence
4.5 It is fundamental that the appraisals are run with assumptions reflective of the current market to ensure that the rates
are set at viable levels. The Consortium is therefore concerned that the Viability Assessment will be relying on data
that has not been updated for some time, such as build cost allowances, is discussed below. It is fundamental that the
CIL rates are formulated on up-to-date evidence, especially since the PDCS consultation is running in parallel with the
emerging Local Plan consultation.

Section 106 Contributions
4.6 There has been no allowance for Section 106 obligations costs within the PBA appraisals for any of their typologies
tested either small or large sites. The PBA Viability Report25
states “On larger sites it is likely that substantial
infrastructure requirements will continue to be considered through S106. However at this stage the specific
requirements are unknown, so in determining a suitable level of CIL, sufficient headroom needs to be available to fund
likely S106 requirements.”26
4.7 As stated in Section 3 we strongly disagree with the methodology taken by GBC, which seems to be to omit any
Section 106 costs and to rely on “sufficient headroom” within their proposed rates. The Consortium feels this is a gross
failure in approach for all typologies but specifically strategic sites, which will not only incur the greatest infrastructure
costs but will be responsible for the majority of new housing supply. Ultimately, this approach risks significantly under-
estimating the true costs of development resulting in unrealistic capacities for sites to pay for CIL.
Infrastructure and Site Opening Costs (“Scheme Enabling”)
4.8 Opening costs have been taken into account for Brownfield Sites at between £150,000 to £200,000 per net hectare for
large Brownfield and Brownfield sites respectively. On Greenfield sites an allowance of up to £20,000 per unit has
been made for sites of over 501 units, with a sliding scale decreasing in allowance by number of units. Although the
Consortium agrees in principle that infrastructure/opening costs should be applied to both Brownfield and Greenfield
sites, we would disagree with the amounts levied. It is felt that abnormal costs and opening up costs are not exclusive,
therefore it should not be assumed that Greenfield sites do not have abnormal costs and conversely that Brownfield
sites do not require substantial costs to enable development.
4.9 Considering Abnormal costs in more detail and using an example site we seek to demonstrate a substantial
underestimation of costs. Site 1627
a 30 unit flatted scheme has site abnormal costs of £60,000, equating to only
£2,000 per unit. PBA consider Abnormal costs would include demolition and remediation works, in principle the
Consortium disagrees with this definition of Abnormal costs and believes typically demolition would be a separate
allowance. It is felt for Brownfield sites the Abnormal costs allowance is acceptable for remediation works only,
additional costs for demolition and the incorporation of opening up costs should also be allowed for to take full account
of the associated costs. An alternative to working out abnormal costs would be to increase the percentage of
contingency which has been allowed for in the appraisals.
4.10 Opening costs for Greenfield sites range from £0 to £20,000 per unit, with the higher figure only applicable for sites of
over 501 units. The Consortium feels this allowance is too low and does not represent realistic costs. Guidance
dictates that infrastructure/opening costs should be set between £17,000 and £23,000 per unit for large scale
developments as per the LHDG ‘Harman Report’ (June 2012)28
.

Promotion Costs
4.11 The cost of promoting a site through the planning process can be considerable, especially with the larger strategic
sites. The viability appraisals provided by PBA do not seem to recognise or allow for these costs and we would
therefore ask that they are considered in further detail prior to setting the CIL rates. This is fundamental for large
strategic sites, notably those which are presently in the Green Belt, which may be subject to extensive promotion
periods.
Build Costs
4.12 The levels of build costs applied within the Viability Study29
are of concern to the Consortium, because build costs have
increased rapidly over the past 10 months as a result of rising material and labour costs. The impact of this is
highlighted in Table 1 below, which shows the movement since April 2014:
Table 1 – Movement in BCIS Build Costs
Source: Savills.
*In order to calculate Medium sized housing build costs, the figures stated for small housing schemes and Estate housing have been
interpolated. The figure given is the median between the two figures stated. Median build Costs, adjusted to Guildford have been used.
4.13 This indicates an average increase of 10.7% in build costs for houses and flats since April 2014. It is therefore
imperative that GBC updates their Viability Study to reflect current build cost estimates. It should also be highlighted
that as the build costs link to a number of other inputs; an incorrect base build costs risks a significant underestimation
of the true costs of development.
4.14 The Consortium was provided with appraisal summaries for each typology after requesting the information from GBC30
.
After reviewing these documents it has become apparent that build costs stated within the Viability Study have not

been used for each typology, some utilising lower build costs. We would therefore ask that GBC provide more
evidence to justify these variations.
4.15 Additionally the Consortium is concerned about the allowance for ‘extra-over’ costs at £450 per unit for compliance to
2014 Building Regulations. PBA comment that England Build Regulations 2014 seeks a 6% improvement to the 2010
Building Regulations standard, and this is unlikely to be reflected in BCIS costs at the time of tender in April 2014. PBA
have therefore assumed a rate of £450 per unit increase in build costs over units that were built under the 2010
Building Regulations, which is taken from the Government’s Regulatory Impact Assessment findings.
4.16 The PBA appraisals do not take into account any increased price for completing homes to a level within the Code for
Sustainable Homes. PBA have assumed that as the Code for Sustainable Homes is to be phased out, GBC have not
indicated within their Draft Local Plan to introduce a mandatory policy requiring development to meet a higher level of
sustainable development. The Consortium disagrees with this view, and feel that even if the Code for Sustainable
Homes is abolished, new homes will still need to conform to a similar level of sustainability through Building
Regulations. This change will require an additional cost and although unknown as this time, it should be factored into
the cost assumptions, chiefly for large scale development which will be built out over a long period of time.
Developers Profit
4.17 PBA has chosen to adopted a profit margin of 20% on Gross Development Value (GDV) for the private housing and
6% on GDV for the affordable housing, reflecting a blended rate in the region of 17.5% on GDV within their appraisals.
We would like to make it clear the minimum profit margin that the lending institutions are currently prepared to accept,
on residential development, is 20% on GDV and therefore the blended profit rate adopted by PBA is below the
minimum level required by national house builders.
4.18 The NPPF states that to ensure viability, developments should provide competitive returns to a willing land owner and
willing developer. A competitive return to a developer is one that provides a sufficient return for the developer to
continue a successful business through the economic cycle, taking account of the risk profile of the business. We are
therefore concerned that PBA’s assumption is too low and does not take account of the minimum returns required by
shareholders of quoted Plc house builders.
4.19 We have attached a report on competitive developer return (Appendix 3), which provides evidence on the minimum
profit margins required by Plc house builders. The key focus is the distinction between gross (site level) margin and net
operating margin. A point discussed in the Harman Report, which suggests that “overheads for house-building typically
lie in the range of 5%-10% of gross development value”. This is particularly relevant for large Greenfield sites and
regeneration areas, where large up-front costs have an impact on a developer’s required Return on Capital Employed
(ROCE), as a higher margin is required to reflect the higher risk. This is new evidence, provided to counter previous
Examiners decisions on profit, which were made in the absence of any evidence on this matter.
4.20 Taking this into account, we would therefore ask that a minimum profit level of 20% on GDV (blended) plus 25% ROCE
across all tenures, subject to consideration of the risk profile of the scheme, is adopted in the viability testing.

Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 17
Benchmark Land Value (BLV)
4.21 The Consortium has a number of concerns relating to the methodology and assumptions made by the Viability Study in
determining the BLVs. PBA state that the “threshold/benchmark land value is based on a review of recent viability
evidence of sites currently on the market, a review of submitted viability appraisal by applicants, published data on land
values and discussions with stakeholders.”31
4.22 The BLVs are based on both serviced land sales with planning consent, and disposals of land (existing use) without
the benefit of planning permission. Land with planning will vastly differ in value to land without planning. It is therefore
unclear how the BLVs have been calculated from these comparables.
4.23 When considering BLVs the Consortium is concerned that these are set too low and do not reflect market expectations,
this is particularly the case for Brownfield sites with higher Existing Use Values. It is concerning that there is no
comparable evidence provided to support the figures stated in the Viability Study. We would therefore ask that GBC
provide more evidence to justify these values.
4.24 The Consortium has provided market evidence of Guildford town centre Brownfield site acquisitions, of these two
comparable sites ranging from a small housing development and high density flatted scheme, the average land value
per Net Hectare has come to Circa £9.9m. Considering the relatively small data set the evidence could be interpreted
as not being fully representative, however this evidence does highlight that the BLVs in the Guildford town centre
fluctuate hugely. This evidence also demonstrates that the BLV set within the Viability Study for Guildford Brownfield
sites at £3,000,000 per Net Hectare should be considered as the lower range and does not truly represent market
expectations.
General Appraisal Assumptions
4.25 The Consortium fundamentally disagrees with a number of the assumptions made by PBA in the Viability Study32
and
appraisal work, in addition to those above:
Timing – The PBA Viability Report does not provide any timing assumptions for build or sales rates or general
appraisal timing. GBC provided further details33
to the Consortium upon request, which states sales rates mirror
build rates with a lag of 6 months. Although rates move with scheme size, the 6 month lag (lead-in) for sales stays
the same. Meaning on large strategic sites it is assumed the first unit sale will be 6 months after ground is broken.
This is an extremely unrealistic assumption and we would request further clarity on the timing assumptions that
have been applied. It must be noted like Build Costs, timing assumptions do not follow the additional information
provided, with some appraisals differing from the adopted assumptions. Lastly it must be noted that no assumption
has been made for the sale of Affordable Housing, meaning it is considered they sell in the same process as open
market units, which is unrealistic and does reflect the market.
Finance – The finance rate is set at 6% of land value. In principle the Consortium has adopted this assumption in
analysis, although a rate of 7% would be more market appropriate.

Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 18
Commercial Elements – The larger typologies for strategic sites make no account for commercial elements of the
scheme, meaning there is a gross underestimation of costs. Much like with site specific infrastructure costs the
Consortium recognises the difficulties in estimating unknown costs, however it is felt an assumption must be made
to account for such substantial costs.
Errors – As mentioned above a number of small errors have been made throughout the appraisals. Although these
issues may seem minor, small changes within a residual appraisal can have huge effects on end values. Within the
Viability Study SAMM costs are to be levied at an average amount of £700 per unit, however this figure becomes
£750 per unit within the appraisals. As alluded to above, often the timing assumptions for sales rates do not follow
the adopted assumption. It has become apparent that the cost of finance in the PBA appraisals differs from our own
mirrored appraisals, demonstrating the need to use industry standard software.

Overall
4.27 The Consortium consider that whilst the general methodology of utilising residual appraisals within the Viability
Assessments is in line with industry practice, the report provided by PBA contains some assumptions which are
concerning the HBF Consortium, which may undermine the validity of the evidence that is being relied upon to justify
the proposed CIL rates. As a result, the Consortium cannot agree to some of the points that have been raised by the
report and feels that the rates set have not been based upon a robust evidence base, where it can be concluded that
development will not be put at serious risk.
4.28 Our clients therefore request that certain elements of the evidence be revised and made readily available, as
summarised by the list below:
Incorporation of a reasonable developers profit;
Incorporation of promotional & abnormal costs on large scale sites;
Evidence of benchmark land values;
Full detailed appraisals assumptions for each typology;
Inclusion of site specific S106 costs for large scale sites; and
Evidence of an appropriate viability buffer – given the proposal to adopt CIL prior to an up to date development
plan.
Part 2 - Alternative Viability Appraisals
4.29 Given the concerns set out above, we have produced a set of alternative viability appraisals in order to demonstrate
the impact of the underestimation of the following on the calculation of the maximum CIL rate:
1) Construction and Sales Timing;
2) Allowance of Abnormal and Infrastructure/Opening Costs;
3) Promotion/Planning Costs;
4) Developer’s Profit;
5) Section 106 Allowance for Site Specific Costs; and
6) Build Costs.
4.30 Savills has sought to reproduce appraisals produced by PBA, however there are a number of issues preventing us
from doing so accurately. The appraisals have been constructed using ‘in-house’ appraisal software rather than
industry recognised software, this has meant there are limitations to the level of accuracy that can be achieved. As
Guildford Borough Council CIL PDCS
Consultation response on behalf of a Housebuilder Consortium
Consortium of House Builders February 2014 21
mentioned above it is not entirely clear as to the timing assumptions for building and sales rates in addition to general
timing assumptions.
4.31 We have been able to reproduce PBA’s 50 and 2,000 unit typology appraisals, as close as possible, and have using
our own ARGUS Developer appraisal software and have incorporated the assumptions set out in Tables 3, 4 and 5
above. We have also created a 400 unit Greenfield typology extrapolating PBA assumptions. We have sought to
produce three specific typologies because we feel this is representative of proposed housing supply and demonstrates
a good cross section of typologies. In addition, for the 400 unit and 2,000 unit typologies, these were in part selected
because we have been able to make reference to exiting and estimated Section 106 cost estimates.

4.33 The results in Table 6 demonstrate when market facing assumptions and a 40% viability buffer is applied, only the
Guildford, Brownfield (Zone 3) CIL rate of £500 appears viable. On the basis of the 400 unit typology it is clear that an
alternative CIL rate would only become viable at between 30% to 35% less than the proposed rate, for East Rural and
West Rural respectively. When analysing the Strategic 2,000 unit typology, the maximum CIL rate is considerably
under the proposed rate. Although the Strategic CIL rate would appear viable, the Consortium is still concerned over
the adopted BLVs, as market knowledge would suggest the BLVs especially for Brownfield sites are set too low;
leading to a significantly lower level of or no headroom. A 40% viability buffer is justified given the potential headroom
for CIL without a buffer (and hence increased risk that more schemes are rendered unviable as each site/ scheme is
different) and also as the housing land supply situation is very poor.

4.34 As stated at paragraph 4.24, market evidence would illustrate that the adopted BLV for Guildford, Brownfield sites is far
too low. The Consortium was able to provide comparable evidence which demonstrates BLVs in the region of
£10,000,000 pre Net Hectare, far higher than PBA. Taking a rough mid-point BLV of £6,000,000 pre Net Hectare, we
are re-assessed the 50 unit typology, which now shows a minus capacity, deeming it unviable. The Consortium has
serious concerns over the adopted BLVs and relatively high proposed CIL rates, accordingly the Consortium seeks
clarity on the comparable evidence utilised to arrive at the BLVs.

4.35 Graph 1 below uses the Savills Benchmarking Model to test the viability of the proposed CIL rate (£400 per sq m)
which is applicable to large scale residential, strategic sites. This is plotted alongside local LPAs with similar sales
values, and with a similar reliance on large scale Greenfield development for housing delivery.
4.36 The box below explains how to interpret the results.

4.37 This indicates that the proposed CIL rate for GBC combined with the current affordable housing policy would render a
significant proportion of schemes unviable. This is concerning as the other proposed CIL rates are higher than £400
per square metre. A trade-off between CIL and affordable housing will therefore be needed if the delivery of these large
Greenfield sites is not to be threatened.

Recommendation
4.38 The Savills appraisals supports the Consortiums view that the proposed CIL rates will jeopardise the delivery of
housing in the Borough and will prevent a five year land supply as required by the NPPF. It is recommended that GBC
revisit the methodology and evidence used to inform BLVs, with a view to bringing them inline with market
expectations. Additionally it is clear from Table 6 above that when utilising market assumptions with the LPA affordable
housing policy and CIL costs, the proposed CIL rates do not provide a sufficient viability buffer to ensure the delivery of
housing and therefore requires substantial reduction. Primarily we would recommend that a £nil charge would be levied
for major strategic residential development and a significant drop in other CIL rates namely Guildford Town (Zone 3) to
ensure future viability.

5. Effective Operation of CIL
5.1 Despite the narrow scope of the Examination, the Consortium urge the Council to make clear at the earliest opportunity
the supporting documentation needed to operate CIL and to make it available for consultation. Practically, this needs to
be done prior to the Examination so that participants and stakeholders are able to comment on the effective operation
of CIL. Whilst this supporting information is not tested at Examination, this information is critical to allow for the
successful implementation of CIL and to demonstrate that the CIL has been prepared positively and supports
sustainable development.
5.2 The documentation should include:
Guidance on how to calculate the relevant chargeable development/level of CIL;
Guidance on liability to pay CIL/Appeals process;
Policy for payments by instalments;
Approach to payments in kind;
Guidance on relief from CIL and a policy on exceptional circumstances for relief from CIL.
5.3 The GBC CIL PDCS does not currently include clear explanation of any of the above. GBC recognise that there is
scope for them to exempt certain development and/or introduce an instalments policy34
.
Mandatory Relief
5.4 The Council must clarify its position as the PPG states “A collecting authority must give full relief from the levy on the
portions of the chargeable development which are intended for social housing”35
.
Instalments Policy
5.5 The Consortium would welcome the introduction of an Instalments Policy. Developer cash flow is an important
consideration, notably in respect of upfront infrastructure costs typically associated with strategic scale development. A
proposed Instalment Policy should aim to reflect, as closely as possible, the timing of delivery of the development, to
ensure that the CIL does not put unnecessary pressure on cash flow and viability.
Payment in kind
5.6 The CIL Regulations now allow for Payment in Kind through the provision of infrastructure. However, there remain
notable deficiencies in the operation of CIL, caused primarily by the CIL Regulations, which places the Council and the
development industry in a difficult position.
5.7 The scope to reduce the CIL liability via utilisation of Payment in Kind is therefore restricted to those items of
infrastructure which are not required to mitigate the impact of a development, which for strategic scale sites would
exclude most (if not all) site-specific and “scheme mitigation” infrastructure.

5.8 Payment in Kind is therefore not a credible option, which further emphasises the need to ensure that the Regulation
123 List does not include any items of infrastructure intended to be delivered through Section 106 agreements on any
of the strategic scale sites.

6. Conclusion
6.1 This representation has been prepared by Savills on behalf of a consortium of house builders. As set out at the start of
this representation there are four key tests at Examination:
i. The charging authority has complied with the required procedures set out in part 11 of the Planning Act 2008 and
the CIL Regulations;
ii. The charging authority’s draft charging schedule is supported by background documents containing appropriate
available evidence;
iii. The proposed rate or rates are informed by and consistent with, the evidence on economic viability across the
charging authority’s area; and
iv. Evidence has been provided that shows the proposed rate (or rates) would not threaten delivery of the relevant
Plan as a whole
6.2 The following points are key concerns for the Consortium:
Unviable Rates - The current proposed CIL rates are unviable in the round and risk rendering a significant
proportion of the housing supply across the District undeliverable;
Incorrect Assumptions - A number of the key viability inputs adopted by PBA are incorrect. Specifically, the
allowance for Section 106 contributions is insufficient with a number of the other costs out of date, this results
in an over-estimation of the maximum CIL rates that can be supported.
Risks for delivery of Strategic Sites – The appraisals relating to the large, strategic residential sites do not
take into account the significant ‘opening up’ and abnormal costs for the delivery of sites this scale. We would
strongly recommend that the Council considers applying a zero rate for their strategic residential development
sites, especially given the stage of the Local Plan process.
Alternative Viability Appraisals - We have undertaken alternative viability appraisals looking at the impact of
Section 106 obligations, profit margin, and abnormal allowances on the level of CIL that can be supported.
6.3 Notwithstanding the concerns about the principle of introducing a charging schedule when there is no up to date Local
Plan, it is necessary to stress that if the CIL level is set too high, it will certainly have a negative impact on a large
proportion of development coming forward, especially bearing in mind the likely reliance on strategic sites in delivering
the housing the District requires.
6.4 The Consortium is open to a meeting with the Council and their advisors to discuss the approach taken and to discuss
amendments to the proposed CIL rate.
