2. Things you need to know about this release

The UK House Price Index (HPI) is a joint production by HM Land Registry, Land and Property Services Northern Ireland, Office for National Statistics and Registers of Scotland.

The UK HPI, introduced in June 2016, includes all residential properties purchased for market value in the UK. However, as sales only appear in the UK HPI once the purchases have been registered, there can be a delay before transactions feed into the index. As such, caution is advised when interpreting prices changes in the most recent periods as they can be revised. Further information is provided in our revision policy.

The UK HPI is an official statistic. We continue to progress with the assessment of the UK House Price Index as a National Statistic.
