Strategic Housing Land Availability Assessment (SHLAA)
The National Planning Policy Framework (NPPF) Paragraph 68 states ‘strategic policy-making authorities should have a clear understanding of the land available in their area through the preparation of a strategic housing land availability assessment’.
The function of the SHLAA is to:
- Identify specific deliverable sites and specific, developable sites or broad locations for growth for residential development; and
- Assess their development potential taking into account their availability, suitability and likely economic viability.
The first SHLAA, published in March 2010, was carried out jointly with Knowsley, Sefton and West Lancashire Council. Updates for Knowsley were conducted in 2011, 2012, 2016, 2022, and 2023.
Call for Sites Exercise
Knowsley Council invites interested parties to submit site suggestions for new housing development at any point after 1 August 2022 to be considered in future SHLAAs.
The primary role of the SHLAA is to identify sites with potential for housing and assess when they are likely to be developed. This enables the council to assess whether there is an adequate local housing land supply. The SHLAA is not a statement of council policy, it does not allocate sites for housing, and it does not signify the start of a new Local Plan. Each year the 1 April will be the base date for the relevant SHLAA.
Interested parties can submit sites they consider suitable for housing through the council’s Call for Sites exercise by completing a Call for Sites Form and including a location plan of the site considered suitable for housing. The council will give due consideration to all sites put forward, but they will be assessed against planning policy and other relevant planning considerations. Submitting details of a particular site does not guarantee that the council will include the site in the SHLAA and the council’s housing supply.
Interested parties can submit sites by emailing a Call for Sites Form and a location plan to [email protected] or by posting them to the following address:
