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 3 February 2026 to Question 108220, on Affordable Housing: Greater London, whether there have previously been revisions of the Greater London Authority’s historical data.

Published Affordable Housing Supply statistics always reflect the latest available data provided to my Department.

Previous revisions to historical data have been made by the Greater London Authority, as well as by Homes England and some local planning authorities.

These revisions have been made in accordance with the policy for schedule revisions to the affordable housing supply statistics in England as set out in Section 6 of its technical notes, which are available on gov.uk here.

Details of the revisions made each year to the publication are available in the technical note corresponding to that year’s publication. For the last three years these can be found in Section 7 of the technical notes, available on gov.uk for 2024-25 here, 2023-24 here, and 2022-23 here.

All the available publications can be found on gov.uk here. Up to and including the 2018-19 statistical release, the technical notes are included in the bulletin and are not a separate document.
