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

To ask the Secretary of State for Housing, Communities and Local Government, under what circumstances affordable homes recorded by the Greater London Authority as started under the 2016 to 2023 Affordable Homes Programme may be reclassified, adjusted, or removed from official affordable housing starts statistics; and whether any such cases have occurred to date.

Published statistics on new affordable housing supply in England, which can be found on gov.uk here, are broken down into starts and completions.

Individual units are not tracked from start-on-site to completion. This is because the data provided directly by local planning authorities is collected on an aggregate basis to reduce burden while providing sufficient detail for use.

The integrity of the data is maintained through thorough quality assurance checks, including cross checking with other data sources, while consistency and comparability are ensured through the detailed published guidance for each question.

The affordable housing supply statistics have been assessed by the Office for Statistics Regulation and at the last assessment their continued Accredited Official Statistics status was confirmed.
