The latest UK House Price Index data published on GOV.UK by HM Land Registry (HMLR) for September 2023 show that average UK house price annual inflation was negative 0.1% (provisional estimate) in the 12 months to September 2023. This was down from the revised estimate of 0.8% in the 12 months to August 2023 and represents the first annual fall in the UK’s average house price since April 2012. UK house price annual inflation has been generally slowing since July 2022, when annual inflation was 13.8%. The provisional estimate for the average UK house price was £291,000 in September 2023, which was little changed from 12 months ago, but above the recent low in March 2023.
The coronavirus (COVID-19) pandemic affected the supply of housing transactions for a period of time. For further information, see Section 7: Measuring the data.
The provisional seasonally-adjusted estimate for UK residential transactions in September 2023 was 85,610, reported in HM Revenue and Customs’ (HMRC’s) Monthly property transactions statistics. This provisional volume estimate for September 2023 is 17% lower than the revised estimate for September 2022 and 1% lower than the provisional estimate for August 2023.
On a seasonally-adjusted basis, the average UK house price decreased by 0.5% in September 2023, following a month-on-month increase of 0.7% in August 2023.
On a non-seasonally adjusted basis, the average UK house price decreased by 0.5% in September 2023, following a month-on-month increase of 1.1% in August 2023.Back to table of contents

House Price Index
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.
A non-seasonally adjusted series is one that includes seasonal or calendar effects.
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.Back to table of contents
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, 15 November 2023). The reports contain full details, including commentary, historical data tables and analytical tools.
It takes time for property transactions to be processed following purchase completion, so transaction volumes available for use in the UK HPI build over time. Each month, as more transactions are processed and more data become available for a given month, UK HPI estimates are revised.
Therefore, caution is advised when interpreting price changes in the most recent periods, since UK HPI estimates are provisional for the most recent months and are revised for 12 months (until the 13th estimate, which is final), in line with the UK HPI revision policy.
HM Land Registry transactions
In recent periods, the total transaction volumes available to calculate UK HPI estimates for the latest months have been lower than historically (see UK HPI Quality and Methodology Information (QMI) Section 2.2: Accuracy). This has arisen from a combination of total transaction volumes falling over the past year (HM Revenue and Customs (HMRC) has reported a 19% fall in the 12 months to September 2023) and a reduction in the proportion of transactions from England and Wales, processed by HMLR, in the first estimate. The sample for the latest estimate is about half of usual volumes. We and HMLR are working together to resolve this, including seeking a greater balance between processing recently received applications and those that are older to help preserve the quality of UK HPI statistics. In the meantime, users should be aware that revisions may be larger than usual in coming months.
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. To address this, we have pooled new build transactions for certain months in England and Wales since 2020. Usually, new build volumes have been pooled for six months, but we have extended the pooling period because of low new build volumes to pool for eight months. This means that:
- 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 includes new build transactions from February and March 2023
- April 2023 includes new build transactions from March and April 2023
- May 2023 includes new build transactions from April and May 2023
- June 2023 includes new build transactions from May and June 2023
- July 2023 includes new build transactions from June and July 2023
- August 2023 includes new build transactions from July and August 2023
September 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 are only available for inclusion in the UK HPI after property purchases have been registered (or submitted for registration in Scotland), so is based on completed sales rather than advertised or approved prices. Registration takes time, so there can be a delay before transactions feed into UK HPI estimates. Estimates for the most recent months are provisional and likely to be revised as more data become available and are incorporated.
The provisional UK HPI estimates for September 2023 are based on approximately 14,000 records for England, which represents roughly 18% of the provisional property transactions estimate, published by HM Revenue and Customs (HMRC). UK HPI provisional estimates for September 2023 also include approximately 6,000 records for Scotland (72% of transactions) and approximately 1,000 records for Wales (22% 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 September 2023 and will be used to revise the UK HPI 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. One reason for this difference is likely from misclassification between residential and non-residential transactions in HMRC data, as stated in their Quality report, though HMRC take steps to reduce this measurement error. Another reason could be that residential property transactions 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. Because of these coverage differences, the UK HPI and HMRC property transactions volumes are not directly comparable, and sales volumes in the UK HPI are likely to be lower than transaction volume estimates published by HMRC.
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.
