Housing supply: net additional dwellings
Source: gov.uk (2025-11-20)

This collection brings together all documents on housing supply: net additional dwellings (formerly known as ‘net supply of housing’).

The housing supply: net additional dwellings statistics, also known as ‘net additions’, track changes in the size of dwelling stock due to:
- new builds
- conversions (for example, a house to a number of flats)
- changes of use (for example, a residential house to an office)
- demolitions
Local authorities compiling this data or other interested parties may wish to see notes and definitions for dwelling stock data (https://www.gov.uk/guidance/dwelling-stock-data-notes-and-definitions-includes-hfr-full-guidance-notes-and-returns-form), which includes Housing Flows Reconciliation (HFR) returns form and full guidance.

MHCLG published a consultation on 30 January 2020, on proposed changes to the revisions policy to further improve the net additional dwellings statistics. Please see the consultation and response (https://www.gov.uk/government/consultations/housing-supply-net-additional-dwellings-statistics-proposed-changes-to-revisions-policy) published on 26 November 2020.

Live tables on housing supply: net additional dwellings

The new data are also incorporated into the detailed data tables (known as live tables) which provide all of the available detail, geographic disaggregations and historic data in the statistical series.

Housing supply: indicators of new supply statistics

We also publish another measure of new builds based on alternative data sources. This alternative measure tracks house building in more detail (recording separately the number of homes that started to be built each quarter and the number completed) and is more frequent, being quarterly rather than annual.

The quarterly housing supply: indicators of new supply statistics (formerly known as ‘house building’) data are based on returns by building control inspectors at local authorities and the National House-Building Council (NHBC). See housing supply: indicators of new supply statistics (https://www.gov.uk/government/collections/house-building-statistics).
