Housing and economic supply evidence (SLAA)
Updated 5-Year Housing Land Supply Statement
September 2025: The Council has published an updated 5 Year Housing Land Supply Position Statement as the adopted Runnymede 2030 Local Plan is now older than 5 years (having been adopted on 16 July 2020). This shows that the Council can demonstrate 2.89 years supply of housing as of 1 April 2025.
Strategic Land Availability Assessment (SLAA)
The Council is required to produce a Strategic Land Availability Assessment (SLAA). The SLAA helps to identify future sources of land to help meet the area’s development needs. It is a technical study which assesses particular areas of land supply in the Borough to determine how far each is suitable, available and achievable (viable) for development or to support development.
The SLAA is updated periodically, and the Council has published an interim version in May 2026, ahead of the outcome of the Green/Grey Belt Review which will inform a further iteration in the latter part of 2026. This is because the findings of this work will inform the SLAA assessment of those sites that are situated within the Green/Grey Belt.
SLAA: Call for sites
The Council will be undertaking a Call for sites for the 2026 SLAA from Monday 7 September 2026 and Monday 12 October 2026 as part Scoping Consultation on the New Local Plan.
As part of the SLAA process, sites can be suggested for housing, employment, retail, leisure, health, Suitable Alternative Natural Greenspace (SANG), Local Green Spaces (LGS), Biodiversity Net Gain (BNG) and other supporting infrastructure, such as suitable areas for renewable and low carbon energy sources, or flood alleviation infrastructure.
The housing category includes general housing (including market and / or affordable homes), self- / custom-build schemes, Gypsy and Traveller and Travelling Showpeople accommodation, student accommodation, accommodation for older people, or a mix of housing types.
If you wish to suggest a new site, or to amend the details of a previously submitted site for the SLAA and / or the Brownfield Register, please complete and then submit the below Site Nomination Form to the Council.
If you do not want to use the above online form, you can email the Planning Policy team and we can send you a Microsoft Word version of the form to complete and return. The completed form and a site plan (1:1250 or 1:2500 in scale), with the boundaries of the site clearly outlined, should both be submitted as attachments in an email to planningpolicy@runnymede.gov.uk or posted to:

As part of the production of the 2025 SLAA, the Council undertook an Urban Area Capacity Study (UACS) which aims to understand the capacity of the Borough’s designated ‘Urban Area’ (in accordance with the Council’s adopted Local Plan policies map) to accommodate new development and identify additional urban sites which have currently not been included through the SLAA process to date. Having systematically reviewed the urban area across the Borough’s ten Settlement Areas, the Study then assesses sites for their potential inclusion in the Council’s SLAA, which will in turn inform site selection for the revised Local Plan.
The Urban Area Capacity Study is Available to view below.
