Supplementary Planning documents and other guidance

Affordable Housing Supplementary Planning Document (SPD)

Further update to the Affordable Housing Supplementary Planning Document (SPD)

A draft update to the Affordable Housing Supplementary Planning Document was prepared and consulted upon for just over 5 weeks in June and July this year. 

Some of the comments received to this consultation were quite substantive and led to some material modifications being made to the SPD. A decision was therefore taken by the Planning Committee on 24 September 2025 to go out for a further round of public consultation on the proposed amendments to the Update to the Affordable Housing SPD.

This consultation will close at 5pm on Wednesday 29 October 2025.

The consultation includes the following:

Affordable Housing Commuted Sums Methodology Review, Dixon Searle Partnership, January 2025 and the four appendices.

Affordable Housing Financial Contributions Study, Stage 2: Final Recommendations, Dixon Searle Partnership, March 2025

Update to the Affordable Housing Supplementary Planning Document (SPD)

Runnymede Borough Council are consulting on an update to the Affordable Housing Supplementary Planning Document, which was adopted in April 2022. The main reasons for updating the Affordable Housing SPD are because:

  • The publication of the updated National Planning Policy Framework (NPPF) in December 2024 and the significant implications that this has on affordable housing delivery in Runnymede, which it is considered need to be clearly spelt out by updating the existing Affordable Housing SPD.
  • Of the difficulties that the Council is being told by developers that they are experiencing in selling affordable housing units on s106 sites to Registered Providers. In particular, it is considered that the existing affordable housing calculator (Appendix 3 of the existing Affordable Housing SPD) is not transparent or easy to use and it is therefore proposed to replace this calculator with a methodology devised by the consultants, Dixon Searle Partnership, that is much easier to apply and more transparent.
  • Having had the Affordable Housing SPD in place for three years, it is considered that it would benefit from several updates. These relate to the following areas - deleting the list of preferred Registered Providers, updating the rounding section of the document to ensure that any rounding still complies with the affordable housing requirement, updating the template s106 agreement in Appendix 2 of the existing SPD and providing further clarification as to what is meant in Policy SL20 with regards to the ‘site being sub-divided to fall under the affordable housing threshold’. 

It is paramount that local people in Runnymede have the opportunity to live in decent and affordable homes.  Securing homes for all is key to ensuring that people have decent life chances and it also helps to build strong communities and boost the economy.

The Council is committed to increasing the delivery of affordable housing, as set out in the Runnymede Housing Strategy Statement 2021-2026 (February 2021). The Council’s aspiration, as set out in the Housing Strategy Statement, is “for sufficient and affordable, good quality housing that is accessible and suitable for local people in Runnymede. We are responding to the changing demographic and economic needs of our communities to deliver housing that promotes health, wellbeing and financial stability.” 

This SPD sets out the Council’s approach to securing planning obligations in respect of affordable housing from new development across the Borough. It also aims to provide clarity and guidance on implementing the Runnymede 2030 Local Plan affordable housing policy (Policy SL20) by setting out when, how and what affordable housing the Council expects in new developments. The Affordable Housing SPD was adopted on 13 April 2022, with implementation from 20 April 2022. Its contents are a material consideration in decision making in the Borough.
