The House of Commons Library has published a paper data on housing supply for district-level and unitary local authorities in England. It can be seen here and says:
Data is available on housing stock broken down by tenure, net supply of new housing, and supply of affordable housing.
Note on local authorities: There have been a number of local authority mergers in recent years, with new local authorities created in 2019, 2020 and 2021. This page shows data for district and unitary local authorities that existed on 1 April 2020. If you select a newly-created local authority, you will also see figures for the years before it was created. We have calculated these by adding together totals for the old district-level local authorities that were merged together to create the new local authority.
