These estimates are preliminary and are subject to revision. All statistics are non-seasonally adjusted estimates, unless explicitly stated otherwise.

The coronavirus (COVID-19) pandemic affected the supply of housing transactions for a period of time. Further information can be found in Section 7, Measuring the data.

The provisional seasonally adjusted estimate of UK residential transactions in March 2023 was 89,560, as shown in HM Revenue and Customs' (HMRC's) Monthly property transactions statistics. This is 18.9% lower than March 2022 and 1.3% higher than February 2023.

House Price Index (HPI)

The House Price Index (HPI) measures the price changes of residential housing as a percentage change from a specific time period (12 months before, or a base period where the HPI in 2015 equals 100).

House price inflation

House price inflation in the UK is the rate at which the prices of residential properties purchased in the UK rise and fall.

Non-seasonally adjusted

A non-seasonally adjusted series is one that includes seasonal or calendar effects.

Seasonally adjusted

A seasonally adjusted series is one that has been subject to a widely used technique for removing seasonal or calendar effects from time series data.

The UK House Price Index (HPI) is a joint production by HM Land Registry (HMLR), Registers of Scotland, Land and Property Services Northern Ireland, and the Office for National Statistics (ONS). HMLR publishes the UK House Price Index reports on GOV.UK (at 9:30am, 24 May 2023). The reports contain full details, including commentary, historical data tables and analytical tools.

Economic statistics governance after EU Exit

More information regarding the new governance following the UK's exit from the EU is available in our UK House Price Index: August 2022 bulletin.

HM Land Registry (HMLR) transactions

HMLR has increased the use of automation in application processing. This means that initial transaction numbers may be lower than pre-coronavirus (COVID-19) pandemic volumes; however, in the medium to long term, this will lead to higher volumes being processed.

We have temporarily changed the date we receive the transaction data from HMLR. As a result, we receive more transactions than those immediately seen in the published HMLR's Price Paid Data datasets.

The processing of new build properties has been more affected than the processing of "old build" properties. So, to address this, we have pooled new build transactions for certain months in England and Wales, which means that:

• September 2022 includes new build transactions from August and September 2022

• October 2022 includes new build transactions from September and October 2022

• November 2022 includes new build transactions from October and November 2022

• December 2022 includes new build transactions from November and December 2022

• January 2023 includes new build transactions from December 2022 and January 2023

• February 2023 includes new build transactions from January and February 2023

March 2023 has not been affected as new builds are excluded from the model for the first estimate because of the nature of their processing.

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 HMLR's Quality and methodology guidance.

Sales volumes

Sales only appear in the UK HPI once the purchases have been registered or submitted for registration in the case of sales in Scotland (based on completed sales rather than advertised or approved prices). Therefore, there can be a delay before transactions feed into the index. Estimates for the most recent months are provisional and likely to be updated as more data are incorporated into the index.

The latest estimates for March 2023 are based on approximately 31,000 records for England, which currently represent roughly 38% of monthly property transactions, as published by HM Revenue and Customs (HMRC). The estimates also include approximately 5,000 records for Scotland (68% of transactions) and approximately 2,000 records for Wales (43% of transactions). This represents the number of records that are available at the time of calculating the UK HPI and not the number of transactions that have taken place. As time progresses, more records will become available for March 2023, in line with our published revision policy.

However, it should be noted that there are some coverage differences between the sales volumes used in the UK HPI dataset and the monthly property transactions statistics data. This means that the two are not directly comparable, and sales volumes in the UK HPI are unlikely to ever reach the transaction levels published by HMRC. It is believed that the main reason for this difference is that residential properties where the buyer or seller is a corporate body, company or business are excluded from the HMLR data in the UK HPI, but included in HMRC property transaction statistics.

Data sources

The main sources of data used in the UK are HMLR for England and Wales, Registers of Scotland, and HMRC's Stamp Duty Land Tax data for the Northern Ireland HPI.

Methods

The method for calculating the UK HPI can be found in HMLR's Quality and methodology guidance.

Quality

More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in HMLR's UK House Price Index guidance on GOV.UK.

Further information on strengths and limitations of the data can be found in Section 1.4 of HM Land Registry's (HMLR's) Quality and methodology guidance.
