1. Overview of house building data

This release provides data on newly built dwellings in the UK. Where possible, data are presented separately for dwellings started and completed, and split by sector (private enterprise, housing associations or local authorities).

Individual country-level statistics are available separately from the producers of each country’s statistics (see Section 4: Related links). The UK data are created by aggregating previously published data from the four UK countries. This article provides the most up-to-date data available for each geographical area and time period at the time of publishing. Data for individual countries may cover more recent time periods.

The UK-level dataset contains three sets of tables, with estimates available for different periods:

  • quarters - ending with the period of Quarter 2 (Apr to June) 2022
  • financial years – up to financial year ending 2022
  • calendar years – up to 2020

Unfortunately, coronavirus (COVID-19) affected quarterly data collection in Wales in 2020 and 2021. Financial and calendar year figures are available for this period for Wales and therefore the UK, but quarterly figures are not available from April to June 2020 until January to March 2022.

The latest house building statistics show that between April and June 2022 there were 54,910 dwellings completed in the UK. By country, the following number of dwellings were completed:

  • 46,230 in England
  • 1,590 in Wales
  • 5,320 in Scotland
  • 1,770 in Northern Ireland

In addition to country level data, we have compiled local authority level house building starts and completions, by financial year. Stakeholder feedback has pointed to a need for these data, and we intend to update them regularly. We welcome further views and feedback, for example by email at better.info@ons.gov.uk.

The statistics presented in this release do not cover all new housing supply. For example, they do not include conversions and changes of use. More comprehensive, but less frequent, housing supply data are published for England and Scotland. These are available for England through the Department for Levelling Up, Housing and Communities' Housing supply: net additional dwellings series and for Scotland through the Scottish Government’s Supply of new housing series. See Limitations of the data in Section 3: Data sources and quality for further information.

3. Data sources and quality

A dwelling is counted as "started" on the date work begins on the laying of the foundation. It is counted as "completed" when it becomes ready for occupation or when a completion certificate is issued.

These statistics are based on administrative data sources. Information about the data sources, and the earliest time periods that data are available from each of the four UK countries, is available as follows.

Data sources by country

  • England: local authority new build form returns; National House Building Council (NHBC) data; approved inspector data returns

  • Wales: local authority building inspectors; NHBC data

  • Scotland: local authority new build form returns; Scottish Government Affordable Housing Supply Programme

  • Northern Ireland: District Council Building Control

Earliest time periods available (starts and completions, and by sector, unless stated)

“Sector” refers to new dwellings constructed by private enterprises, housing associations, or registered social landlords and local authorities. Other data providers may use the term “tenure”. Statistics on starts for Wales are not available split by sector from the financial year ending 2012.

Data by country, quarterly

  • Wales: April to June 1974 until January to March 2020; April to June 2022 onwards
  • England, Scotland, Northern Ireland: January to March 1978 onwards

Data by country, by financial year

  • England, Wales, Scotland and Northern Ireland: year ending March 1970 onwards

Data by country, by calendar year

  • Scotland: 1945 onwards, completions only
  • England: 1946 onwards
  • Wales: 1946 onwards, completions only
  • Northern Ireland: 1949 onwards, completions only

Data by local authority, by financial year (earlier time periods are available from the original sources)

  • England, Wales and Scotland: financial year ending March 2010 onwards
  • Northern Ireland: financial year ending March 2015 onwards


Each publication of these UK statistics will reflect the revisions made in the source data from each country. This ensures that statistics for the UK are consistent with the latest statistics, at time of publication, in each constituent country.

Uses and users

The datasets in this release give timely information relating to starts and completions of new dwellings in the UK. They are used to inform government housing policy, and for housing market analysis and research. They are also used by forecasters and decision-makers, including at the Bank of England. The compilation of the UK data in this release also allows international comparisons of housing supply.

Limitations of the data

Each country produces its own statistics on house building, that are subject to revisions and have variations in sources and how the data are collected and processed. For example, Scotland’s data contain estimates for a small number of local authorities.

A small amount of data for England are missing and therefore imputed. England’s figures do not include data sources that become available later on, such as local authority returns. These reports capture additional new builds to those reported in the sources used in this release, based on building inspector reports.

Figures on new build dwelling starts and completions for England are from records kept for building control purposes. The house building figures reflect the sector of the developer building the dwelling, rather than the intended final sector. This may lead to an undercount of housing association and local authority starts and completions recorded in these tables, and a corresponding overcount of private enterprise figures. This problem is more likely to affect starts than completions.

For Wales, data are based on the reports of local authority building inspectors and the NHBC, a private approved inspector; it does not include information from other private approved inspectors.

It is sometimes difficult for building control officers and the NHBC to identify the intended final tenure of the property (the basis for the tenure information). This may lead to an under-count of social sector new house building and an over-count for the private sector in Wales. Within the social sector, it may also lead to an under-count of local authority new house building and an over-count for the housing association sector. Therefore, the sector data should be treated with caution.

In Scotland, it is not possible to directly identify housing association starts. Therefore, housing association new build approvals are used as a proxy for housing association new build starts.

Northern Ireland data count of the number of starts and completions inspections conducted by building control officers in each council area. The date of a new dwelling start is the date that the first building control inspection takes place, rather than when the foundations are laid.

These statistics provide a timely leading indicator of housing supply, however, there are limitations of coverage and comparability. For England, more comprehensive (but less frequent) measures of changes to the size of the dwelling stock are published annually in the Department for Levelling Up, Housing and Communities' Housing supply: net additional dwellings series. These figures provide a fuller measure of new housing supply based on additional sources, including building control, site visits, and Council Tax and planning databases. Similarly for Scotland, the annual Supply of New Housing series provides data on refurbished and converted dwellings alongside new builds, for financial years.
