Recommendations

Committee is asked to:

 

1.    Approve the Housing Delivery Test Action Plan 2024.

2.    Agree publication of the Housing Delivery Test Action Plan 2024 on the Council’s website.

Reason for Recommendation

The completion of the Plan is a requirement because only 61% of the housing needs have been delivered over the last three years. This is the planning quantitative measurement of housing need. However, the affordable rented housing need is not being met as in the last five years, only three years had affordable rented new build completions (65 units). The Plan identifies actions to address under delivery against the housing requirement in the area. The Plan looks at the reasons for under delivery and the steps to be taken to drive up housing delivery in the area.

 

1.            Summary of the report

 

What is the situation

Why we want to do something

      Only 61% of the borough’s housing needs have been delivered over the last three years. This is the planning quantitative measurement of housing need. However, the affordable rented housing need is not being met as in the last five years, only three years had affordable rented new build completions (65 units).  

      The completion of the Housing Delivery Test Action Plan is a Government requirement (we are under-delivering).


 

 

 

This is what we want to do about it

These are the next steps

      The plan looks at the reasons for under delivery and the steps to be taken to drive up housing delivery in the area.

      Adopt the Action Plan and deliver the actions to increase delivery.

 

1.1              This reportseeks to outline the content of the HousingDelivery Test Action Plan 2024. The Action Plan is a requirement because only 61% of the housing needs have been delivered over the last three years.

1.2              The Housing Delivery Test Action Plan 2024 identifies actions to address under deliveryagainst the housingrequirement in the area. The Plan looks at the reasons for under delivery and the steps to be taken to drive up housing delivery in the area.

1.3              The Plan’s year is 2024 rather than 2025 as the data is calculated to 31/03/24.

2.            Key issues

2.1              The HousingDelivery Test (HDT)has been introduced by the Government as a monitoring tool to demonstrate whether local areas are building enough homes to meet their housing need. The HDT, which was published in December 2024, updates the previous results in 2018 - 2023. The test compares the number of new homes delivered over the previous three years with the authority’s housing requirement. In the case of Spelthorne, the housing requirement is the minimum annual local housing need figure (631per annum as of April 2024).

2.2              The calculation for Spelthorne is given as:

992(homes delivered) / 1632 (homesrequired) = 61%.

It shouldbe noted that the Government’s housing deliverytest only considers the quantum of dwellings which have been delivered, it does not reflect the acute affordable housing need which remains grossly unmet in Spelthorne.

2.3              The HDT was originally introduced in a phased approachover three years. It will have the following consequences:

 

·         Where housing delivery over the previous three years has been less than 95% of the housingrequirement, LPAs shouldprepare an action plan setting out the causesof under delivery and the intendedactions to increase delivery.

·         Where deliveryhas been less than 85% of the housing requirement, a 20% buffer should be applied to the supply of deliverable sites for the purposes of housing delivery assessment.

·         Where delivery has been less than 75% of the housing requirement, the National Planning Policy Framework’s (NPPF) presumption in favour of sustainable development will apply. The three year transitional periodhas now ended therefore the HDT consequences will be standardized moving forward.


2.4              As a consequence of the HDT being 61%, the local authority falls into the category where the following apply:

·         an actionplan should beprepared,

·         a 20% housing bufferfigure is appliedto the housing requirements; and

·         a presumption in favour of development within the boroughapplies as the housing delivery over the last three years is less than 75%.

The proposedaction plan demonstrates that Spelthorne Councilis taking positive steps and is serious about housing delivery.

The presumption in favour ofsustainable development means that proposed developments should be granted planning permission unless their adverse impacts "significantly and demonstrably" outweigh their benefits.

An analysisof the 2023 position in all Surreyauthorities is containedin Table 8 of the Action Plan. Other Surrey Local Planning Authorities (LPAs) with the same ‘consequences’ are Epsom and Ewell (38%), and Tandridge (42%).

 

2.6              The HDT Action Plan isthe Council’s responseto the challenge set out in the Government’s National Planning Policy Framework to boost significantly the supply of homes and has four goals:

 

·         To examinethe possible causesof the ‘under delivery’ of new homes in the Borough.

·         To explainwhat the Councilhas been doing so far to boosthousing delivery.

·         To build relationships with developers, landowners and agents responsible for building homes on sitesthat have planningpermission, allowing the Council to adopt the role of an enabler of much needed residential development ensuring housing permissions are built out as quickly as possible.

·         To set out what actions the Council can take to increase the rate and number of homes built in Spelthorne.

 

3.            Options analysis and proposal

3.1              The first section of the report examines the Action Plan context.These include Spelthorne’s corporate documents which play a role in housing delivery. It should be noted that this action plan does not play any role in deciding the future of the currentGreen Belt or proposed housingallocations. These have been dealt with completely separately as part of the of the emerging new local plan.

3.2              The next section is an assessment of the ‘under delivery’ of newhomes in the Borough including a review of the potential reasons behind the housing supply deficit. This includes the local and national issues which influence housing delivery, (i.e., affordability issues, proximity to London, build costs, post Covid 19 impacts, difficulties once development has commenced). A range of data and sources have been used to inform this analysis. As part of this process, the Council has engaged with stakeholders to improve its understanding of the issues effecting housing delivery. The analysis of the issues has been used to inform what actions the Council need to take to improve its housing delivery.

3.3              Critically, the final sectionof the action plan includesa number of measures to improve decision making and also to support wider opportunities. These include, amongst many:

·         working with site promoters and other stakeholders to deliver Local Plan allocations,

·         continuing to improve planningperformance on speed and qualityof decision making,

·         refining the Planning DM computer softwareand procedures to enhance agile / paperless working in DM; and to

·         constantly reviewing the discharge of planning conditions (after planning permission has been granted) to speed up the process.

 

3.4              The Action Plan identifies future actions to boost housing delivery, including the need to ensure the Local Plan is adopted by the end of 2025. The Council’s assets offer a positive opportunity to boost housing deliveryfurther moving forward (which will be done in partnership with others), however barriersto development will need to be reduced.  Once adopted, the Local Plan will providemore certainty as to the Council’s housing land supply and will help to deliver housing to meet the Borough’s development needs.

 

3.5              We have reviewed our Action Plan against other Local Planning Authorities and best practice and details are contained in Appendix B.  A further analysis will be undertaken in 2026.

 

4.            Financial management comments

4.1              There is a need ensure the Local Plan is adopted by the end of 2025, in order to provide greater certainty to developers, to avoid further delaysin meeting the Borough’s housingneeds and to reduce the risk of potentially costly appeals where applications are overturned or refused and then allowed on appeal.  There is no specific budget set aside for such eventualities – all these costs come out a reserve which will diminish over time.  A HDT of below 75% will also provide an increased financial risk associated with the costs of defending planning appeals.

 

5.            Risk management comments

 

5.1       There are no known consequences if Spelthorne failsto produce an action plan when required to.  The government will not intervene if our housing delivery test level (%) does not increase, this only happens at present when there is poor performance in the speed and quality measurements of major and non-major applications. Consistent under-delivery could harm the authority's reputation in terms of housing delivery impacting public and private sector investment.

5.2       However, Spelthorne is at the highest (worst) level in the ‘consequences’ of the housing delivery test regime.  A 20% housing buffer is applied to our 5 year housing land supply figures for consistent under delivery.  We are also required to produce an Action Plan to demonstrate how seriously we seek to address this issue.  Finally, there is a presumption in favour of approving development in our decision making process.  This presumption will remain even when the Local Plan is adopted and we have a 5 year housing land supply as we are required to meet both targets.

5.3       If the HDT remains below 75% (we are at 61%) the presumption in favour of sustainable development will remain and this will carry significant weight in the determination of planning applications for housing developments. 

 

5.4       A HDT of below 75% will also provide an increased financial risk associated with the costs of defending planning appeals, particularly the more costly Hearings and Local Inquiries.  Local Planning Authorities are required to fund their own costs in defending planning applications at appeals, including the cost of counsel.  These costs can be significant and can extend to over £100,000 for very large and complex appeals.

 

5.5       A HDT of below 75% will give housing delivery “very substantial weight” in decision making, thereby increasing the risk of development being allowed on unsuitable sites within the borough. An increase in approval of speculative development on unsuitable sites could lead to strain on local infrastructure and services through an “unplanned” and not strategic approach to infrastructure delivery.  

 

5.6        The anticipated adoption of the new Local Plan in September 2025 will support the delivery of new homes in the borough, through the allocation of development sites and the release of Green Belt for family homes. The new Local Plan projects the delivery of almost 10,000 homes up to 2039, which will improve the Council’s Housing Delivery Test result. However given the nature of the Housing Delivery Test, which takes an average of the past three years of housing delivery, it may take some time for the impact of the new Local Plan to filter down into the results of the HDT.

 

5.7       Whilst the Council has identified actions to address past under delivery in housing, it should be noted that there are factors beyond the Council’s control that may negatively impact housing delivery, for example market forces or developer priorities. These may limit the impact of the Council’s actions set out in the plan.

 

6.            Procurement comments

6.1              There are no procurement issues.

 

7.            Legalcomments

7.1              The National Planning Policy Framework requires that, where the HDT indicates that delivery has fallen below 95% of the local planning authority’s housing requirement over the previous three years, the authority should prepare an action plan in line with nationalplanning practice guidance (PPG), to assess the causes of under-delivery and identify actions to increase delivery in future years.

7.2              Once approved, the Action Plan demonstrates not only the council’s commitment to responding positively to the challengeof increasing housing delivery but also is a measure of good practice to identify ways to support delivery. However, most importantly it provides compliance with the framework’s and the PPG’s requirement for an action plan.

 

8.            Other considerations

LocalPlan

8.1              The Local Plan 2024-2039, will guide development in the Borough to 2039/40. Ensuring timely progress on the Local Plan will help the Council to boost its housing delivery by givingcertainty, address some of the issues raised in the HDTAP and give the Council more decision-making powers.  Failing to meet our housing needs means we will continue to be subject to the most severe sanctions of the HDT.

 

Local Government Reorganisation

8.2                        Changes to the HDT will occur with LGR as there will be different geographical areas covering housing needs and delivery with the forthcoming amalgamation of boroughs and districts.  However, this has not yet been agreed by Government and consequently it is too soon to say how this will fall out.  This matter will be updated in 2026.

 

9.            Equality and Diversity

9.1              This reportdoes not have any directequality and diversity impacts although the LPA will continue to require all housing schemes to have regard to equality and diversity issues.

 

10.         Sustainability/Climate Change Implications

10.1     This report does not have any directsustainability/climate change implications although the LPA will continue to require housing schemes to comply with current policy guidance on sustainability/climate change issues.

 

11.         Timetable for Implementation

11.1         The agreedplan should be made available to the publicvia the websiteas soon as possible.

11.2         The agreedplan will be reported to the PlanningCommittee for information as soon as possible.
