Housing Supply and Planning Applications England 2023

The purpose of this release is to provide an indication of the levels of and trends in new housing supply in England. This statistical release presents National Statistics on building control reported estimates of housing supply in England up to 31 March 2023. This release also presents estimates of housing supply in England using other additional data sources.

The ‘new build dwelling’ figures are based on building control inspection data submitted to the Department by local authorities, the National House Building Council (NHBC) and other independent approved building control inspectors. This series began in 1946 based solely on local authority building control. NHBC data were added from 1985 and, after 2007, legislation allowed data from independent approved inspectors.

The Department for Levelling Up, Housing and Communities (DLUHC) also publishes an annual release titled ‘Housing supply: net additional dwellings’, which is the primary and most comprehensive measure of housing supply. This includes figures for new house building, conversions (for example a house into flats), change of use of an existing building (for example a shop into a house or a barn conversion), other gains/ losses, and demolitions.
