Northern Ireland revision tables
Land & Property Services has found a small error in the Northern Ireland revision tables. The error does not affect the March 2021 index. See Northern Ireland House Price Index - revisions tables Q1 2016 for more information.
Northern Ireland sales volumes
We’ve changed the way we publish the Northern Ireland sales volumes and corrected the way we include them in the UK figures. We’ve produced a monthly estimate by dividing the total sales volumes for the quarter in Northern Ireland by 3.
We previously included the quarterly Northern Ireland data in the monthly UK sales volumes data, which resulted in higher than expected sales figures.
Methodology change for new build property
Because of the impact of the coronavirus (COVID-19) pandemic on both the number and supply of housing transactions, some methodology changes have been made. The processing of new build properties has been more affected than the processing of “old build” properties. To address this, we have had to pool new build transactions for:
- December 2020 to include new build transactions from November and December 2020 for England and Wales
- January 2021 to include new build transactions from November 2020, December 2020 and January 2021 for England and Wales
- February 2021 to include new build transactions from December 2020, January 2021, and February 2021
Due to the nature of the processing new builds, these are never included in the model for the first estimate, so March 2021 has not been affected.
These changes might lead to larger revisions to published estimates than usual as we reduce the reliance on pooling. Further information on how we usually process the new build properties can be found in the Quality and Methodology documentation.
