Introduction

The information is based on the reports of local authority building inspectors and the National House Building Council (NHBC). Tenure data should be treated with caution (see Notes for further information).

[Note 1] Quarterly data was not collected for 2020-21 or 2021-22 due to the coronavirus (COVID-19) pandemic.

  • Between April and June 2024, 1,011 new dwellings were started, 19% fewer than the same quarter of 2023 (1,248). 
  • Between April and June 2024, 1,342 new dwellings were completed, 21% more than the same quarter of 2023 (1,108).
  • More than half (57%) of new dwellings completed between April and June 2024 contained three or more bedrooms.
  • Compared to the same quarter of 2023, there was a substantial increase in the number of one-bedroom dwellings completed (from 104 to 270). 

New dwellings completed by tenure

This split should be treated with caution as it is believed to include an undercount of social sector builds and an overcount of private sector builds. Within the social sector, there may be an overcount of Registered Social Landlord (RSL) builds and an undercount of local authority builds (see Notes for further information).

  • Between April and June 2024, most new dwelling completions were accounted for by the private sector (71%), with a smaller proportion accounted for by RSLs (23%) and local authorities (6%).
  • Compared to the same quarter of 2023, the proportion of dwelling completions accounted for by the social sector increased from 22% to 29%.

Notes

  • Due to rounding, some figures may not add up to 100%.
  • This data is based on the reports of local authority building inspectors and the National House Building Council (NHBC) a private approved inspector. It does not include information from other private approved inspectors. It is sometimes difficult for building control officers and NHBC to identify the intended final tenure of the property (the basis for the tenure information). This may lead to an under-count for the social sector and an over-count for the private sector. Within the social sector it may also lead to an under-count of local authority new house building and an over count of RSL house building. Therefore, the tenure data should be treated with caution. 
  • Both starts and completions will be influenced by quarterly fluctuations, including the timing of starts and completions on large sites in some authorities and seasonal factors such as holidays and weather. These statistics are not seasonally adjusted.
  • We also publish separate statistics on affordable housing provision. The figures cover all additional affordable housing units, whether through new build, purchase, acquisition, leasing or conversion of existing dwellings.

Headline figures and StatsWales data are published quarterly and a report is published annually. The information published on StatsWales includes local authority level data as well as the number of new dwellings completed by dwelling type and number of bedrooms.
