Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, pursuant to the Answer of 9 July 2025 to Question HL8844 on Affordable Housing: Finance, what measure of inflation was used to provide the statistical basis for the valuation of the programme.

At the Spending Review, the government announced £39 billion for a new Social and Affordable Homes Programme (SAHP) over 10 years from 2026-27 to 2035-36.

The Spending Review document sets out that spend on the SAHP will reach £4 billion per year in 2029-30 and rise in line with inflation subsequently.

The programme follows the financial appraisal as set out in the HM Treasury Green Book guidance and uses HMT’s GDP deflator which can be found on gov.uk here.

My Department will continue to publish capital spend figures in its Annual Report and Accounts.
