New house building completions are the main component of net supply of housing, which measures the absolute change in the dwelling stock between 1 April and 31 March the following year.

A national system for collecting information about surplus public sector land did not exist in 1997. In 2004, the Government established the Register of Surplus Public Sector Land which now requires Government Departments to register land that is to be disposed of, for any future use including housing.
However, as part of the Surplus Public Sector Land programme, the Homes and Communities Agency (previously English Partnerships) has been working with Government Departments and other bodies to collect information about land they have sold that has subsequently been used for housing. The information available does not include schools but shows that the number of homes built since 1997 on the following bodies’ surplus land were as follows:
Number Ministry of Defence 10,871 National Health Service/Department of Health 30,474 Government bodies (British Waterway, DEFRA, Homes and Communities Agency) 18,160
These figures are likely to under-represent the number of homes built on land formerly owned by Government bodies. However, more detailed information cannot be provided without disproportionate cost.
