The UK House Price Index (UK HPI) captures changes in the value of residential properties.
The UK HPI uses sales data collected on residential housing transactions, whether for cash or with a mortgage. Properties have been included:
- in England and Wales since January 1995
- in Scotland since January 2004
- in Northern Ireland since January 2005
Data is available at a national and regional level, as well as counties, local authorities and London boroughs.
1.1 Experimental statistics
The new UK House Price Index (HPI) was launched in June 2016 initially as an experimental statistic:
- to allow for users to get used to the format of the new HPI
- to evaluate user reaction to the new data
- to evolve the publication of data further to meet user requirements and
- to further develop the data sources used in the production
In September 2016 users of the index were invited to complete a questionnaire to help evaluate different aspects of the report and associated data. We have used these responses to make improvements. The first of which were implemented in December 2016 with a second phase of development scheduled to be implemented in summer 2017. Further details on these improvements can be found in our summary of responses.
Following a review of our revision policy we are looking to extend our revision period to 12 months, this will come into effect from 13 June 2017. This will ensure all relevant transactions will be captured within the UK HPI.
Since the launch of the UK HPI we have found that our provisional estimate for new builds can be quite volatile as it is based on a small initial sample. Due to this, since May 2017 a factor has been applied to help control for the volatility of the new build series. As the provisional estimate for new build properties may be misleading if taken out of context, the average house price, index and associated growth rates for the new and existing property breakdown will be suppressed for 2 months. This change will come into effect for the December 2017 publication.
While we are yet to secure additional property attribute data (such as from Scottish Assessors) we are able to match 95% of the price data to our existing sources of property attribute data and therefore view the existing attribute data sources to be of a good quality. We will continue to explore additional data to supplement our existing sources but no longer consider additional attribute data to be a criterion for being an experimental statistic.
As such, following the implementation of our new revision policy from 13 June 2017, changes to new and existing properties from August 2017 and our second phase of improvements, scheduled to be implemented in summer 2017, we will look to remove the experimental status and progress with the assessment of the UK House Price Index as a National Statistic.
Note that the Northern Ireland Residential Property Price Index, used as a component source in the production of the new UK HPI remains an official statistic (for example this is not classified as experimental).
2. Data sources
The main sources of price paid data used in the UK HPI are HM Land Registry for England and Wales, Registers of Scotland and Her Majesty’s Revenue and Customs Stamp Duty Land Tax data for the Northern Ireland Residential property prices index (RPPI).
2.1 HM Land Registry for England and Wales
Information on residential property transactions for England and Wales, collected as part of the official registration process, will be provided by HM Land Registry for properties that are sold for full market value. The dataset contains the sale price of the property, the date when the sale was completed, full address details, the type of property (such as detached, semi-detached, terraced or flat), if it is a newly built property or an established residential building and a variable to indicate if the property has been purchased as a financed transaction (for example using a mortgage) or as a non-financed transaction (cash purchase).
All this information is currently published by HM Land Registry in its Price Paid Dataset (PPD), with the exception of the funding status indicator. This is not publicly available as this data is considered personal information and would breach data protection rules.
There are a number of registrations excluded from the version of the Price Paid Data (PPD) used in the UK HPI. These are:
- all commercial transactions
- sales that were not for full market value
- transfers, conveyances, assignments or leases at a premium with nominal rent which are:
- ‘Right to buy’ sales at a discount.
- subject to an existing mortgage
- to effect the sale of a share in a property
- by way of a gift
- under a Compulsory Purchase order
- under a court order
- to Trustees appointed under Deed of appointment
- Vesting Deeds Transmissions or Assents
- of more than one property
- leases for seven years or less
2.2 Registers of Scotland
Registers of Scotland (RoS) provides residential property sales for Scotland in the calculation of the new UK House Price Index (HPI). The Scotland data follows a similar process to the Price Paid Data (PPD) where the data provided for the HPI is a by-product of the Scottish property registration process, whereby property sales are submitted to RoS on completion of a sale. Data is gathered from these applications and entered into the RoS Land Registration System (LRS). A weekly extract of all sales data is then taken from LRS and undergoes a quality assurance process to check the price paid, date of entry, property type (land, commercial, residential, forestry, agricultural and other) and to identify market value residential sales (as opposed to non-market sales similar to those detailed for PPD). This data is then combined with further details, such as full address and house type (detached, semi-detached, terrace or flat), using the RoS Geographical Information System database to provide a comprehensive source of data that can be provided each month for use in the new HPI.
In addition, a funding status indicator and a new build indicator are also added to the final dataset. The funding status indicator is identified by whether the applications for registration of a market value residential sale also contain an application for registration of a standard security mortgage deed. All applications with a mortgage deed are mortgage sales, while all those without an accompanying mortgage deed are marked as being a cash sale. The new build indicator is given to every sale of an individual property from a builder’s development title. The coverage of the RoS data differs to the PPD slightly in that transactions relating to residential properties where the buyer or seller is a corporate body, company or business are included within this dataset.
2.3 Northern Ireland data
The Land & Property Services/Northern Ireland Statistics & Research Agency house price index will continue to be calculated and published quarterly. Northern Ireland data will be provided to Office for National Statistics (ONS) quarterly, and will be combined with the Great Britain data to give overall figures for the UK. The overall UK figure will be calculated by keeping the house prices in Northern Ireland constant for each month in a quarter. In the two months following the end of a quarter, when Northern Ireland results for the most recent quarter are not yet available, indices and house prices for Northern Ireland will be carried forward from the previous quarter. They will then be revised when the quarter is complete.
2.4 Council of Mortgage Lenders – Regulated Mortgage Survey
The Regulated Mortgage Survey (RMS) is the Council of Mortgage Lender’s version of the Mortgage Product Sales Data (PSD) that all regulated lenders report to the Financial Conduct Authority (FCA). This is detailed transaction level data on mortgage completions. Starting in April 2005, the RMS now contains over 12 million individual mortgage sale records.
It is collected electronically, with all reporting firms submitting according to FCA-defined data definitions, and in a standard xml format, ensuring consistent data structure. Data coverage is estimated to be around 95% of all regulated mortgages currently advanced. However, some lenders do not permit their data to be transferred to third parties, like ONS, so the share of the market covered by data received by ONS is about 70%.
Reporting fields include purchase price, completion date of property sale, type of borrower (first time buyer (FTB) or home mover) new or second hand property, type and size of dwelling. The RMS is the only comprehensive source of data available for the type of borrower and provides the necessary data to allow the new HPI to be produced according to whether the buyer is a first time buyer or an existing owner. The RMS is also a key source of data used in the production of house prices for inclusion in the Retail Price Index and will continue to be for the foreseeable future.
3. Property attributes data
There is comprehensive data available on the price of transacted property across the UK; however, this price data is limited in terms of details regarding the physical characteristics of the property.
The use of price data alone is insufficient for the calculation of an inflationary index for house prices due to the fact the composition and type of property sold can differ vastly between periods. Therefore, in line with recognised international best practice, hedonic regression and mix-adjustment is used to account for the change in composition.
For a hedonic regression model to be work sufficient, details regarding the attributes of properties sold are required to supplement the price paid data. For the production of the UK HPI, these attributes are available from a number of official sources described below.
3.1 Valuation Office Agency Council Tax Valuation list
The main source of property attributes data that will be used to supplement Price Paid Data (PPD) for England and Wales is administrative data taken from the Council Tax Valuation list maintained by the Valuation Office Agency (VOA).
The VOA has been responsible for banding properties for Council Tax since the tax was first introduced in 1993; before then, the VOA was responsible for the earlier system of domestic rates. The Council Tax Valuation list is a robust source of property attributes (such as the size of the property) data that covers, in principle, all residential properties in England and Wales.
3.2 Land and Property Services Northern Ireland Valuation List
Land and Property Services maintains the list of Northern Ireland properties which are valued for rating purposes. The data are maintained and validated similarly to the VOA data described above. The Valuation List database contains all the property attributes required for the hedonic regression used in the production of the Northern Ireland Residential property prices index (NI RPPI).
3.3 Energy Performance Certificates Scotland
Scottish Energy Performance Certificates (EPC) is used to provide the floor area of the property and the number of habitable rooms required for calculation of the new HPI. This will be matched against the price paid data provided by RoS (using the address details of the property).
3.4 ACORN classification
A key determinant of house prices is the demographic characteristics of the area in which the property is located, such as the affluence of those people living in the area. A well-established geo-demographic segmentation of the UK is available through the ACORN dataset, produced and licensed by CACI Ltd. ACORN segments postcodes into categories and groups by analysing significant social factors and behaviours.
4. Calculating the UK HPI
The calculation of the UK HPI is performed by the Office for National Statistics. The UK House Price Index (HPI) Quality and Methodology Information document contains important information on: the strengths and limitations of the data, users and uses of the data, how the output was created and the quality of the output including the accuracy of the data”
The UK HPI applies a hedonic regression model that utilises the various sources of data on property price (for example the Price Paid dataset) and attributes to produce up-to-date estimates of the change in house prices each period.
More details of the UK HPI methodology (PDF, 522KB) on the ONS website.
4.2 Geometric mean explained
There are different ways of calculating average prices. These include the arithmetic mean (simple mean), the geometric mean and the median.
The arithmetic mean is greatly influenced by the few high value properties and will therefore not give a true reflection of the average price of a standardised property.
The geometric mean reduces the weighting given to high value properties when compared to the arithmetic mean and is typically lower, usually closer to that of the median.
For the UK HPI, the standard average house price is calculated by taking the average (geometric mean) price in January 2015 and then recalculating it in accordance with the index change back in time and forward to the present day.
A 3 month moving average has been applied to estimates below the regional level. For example, at the local authority level, the published estimate for March is a simple average of the calculated estimates for January, February and March. This helps remove some of the volatility in the series at this level. Volatility still remains in estimates for local authorities with fewer transactions, such as Shetland, Orkney and the Western Isles. Northern Ireland estimates are unaffected by this as they are only available on a quarterly basis.
4.3 Monthly and annual price changes
The ‘annual’ percentage change in house prices is simply the price change relative to the same month twelve months earlier. For example, if the HPI release is for February, then the ‘annual’ price change reports the percentage change in values relative to February in the previous year.
This annual rate of price change reflects the best estimate for how much the value of a typical property has changed over the preceding twelve months. Similar to the ‘annual’ change, the ‘monthly’ percentage change estimates the percentage change in average house prices relative to the previous month.
4.4 Revisions to the UKI HPI data
The amount of time between the sale of a property and the registration of this information varies. It typically ranges between 2 weeks and 2 months. Occasionally the interval between sale and registration is longer than two months; this is particularly true for new builds. For example, our provisional (first) estimate for a particular month is calculated on around 40% of the transactions that will ultimately get registered with the second and third estimates calculated based on around 80% and 90% of the final registered transactions. Revisions to the UK HPI estimates arise as the index is re-calculated to incorporate these additional transactions.
Transactions involving the creation of a new register such as new builds are more complex and require more time to process. We aim to complete 60% of these within 25 working days but an increase in applications has created a backlog. As a result, processing times are longer than we aim for. See About our services for details.
The following table summarizes the revision policy for the UK House Price Index.
|Frequency of publication||Frequency of revisions||Period revision covered||Reason|
|Monthly||Monthly (Quarterly for Northern Ireland data)||Previous 12 months (4 quarters for Northern Ireland)||Inclusion of additional registered transactions|
|Ad hoc or other revisions||The entire dataset||- Improvements in methodology
- Large scale revisions to historical data series
- Processing errors
As an example, in the June 2017 release, which contains data up to April 2017, average prices, indices, growth rates and sales volumes previously published for all months between April 2016 and March 2017 will be revised. Northern Ireland quarterly data will be revised back to Q2 (April to June) 2016. This may differ to the revision policy of the Northern Ireland House Price Index published by the Land and Property Services Northern Ireland
From time to time revisions will need to be made outside of the usual. Examples of such revisions include improvements to methodology, revisions to data and the discovery of incorrect data through extensive quality assurance procedures. Each of these revisions will be examined to see if the effects are significant in terms of the degree of change or whether the changes affect the story the data portray. If revisions arising through improvements to methodology or changes to source data are found to be insignificant, they will be introduced in the next planned set of revisions according to the timetable above.
However, if these revisions are thought to affect analysis or are sufficiently large, they will be introduced more quickly.
If incorrect data are discovered after publication, these too will be examined for their impact. Where the changes are significant, a correction notice will be issued as soon as is practicable, while minor corrections will be included in the next planned release. In all cases a full explanation will be included as part of the release.
To view the most recent monthly or ad-hoc revisions to previous data, see the tables provided on the data downloads pages.
4.5 Seasonal adjustments
Seasonally adjusted series are calculated at the regional and national level only. These data can be found within the data tables.
The UK HPI measures nominal house price changes and is not adjusted for inflation. Users of the UK HPI can make their own inflation assumptions and adjust the UK HPI accordingly.
4.7 Small local authority districts not shown on the UK HPI
Due to the small volume of sales for these areas, the UK HPI would not always provide a reliable measure of price movement. This may become possible as the amount of data increases.
4.8 Recent volumes not reported
There are partial sales volume data for the months immediately preceding the UK HPI release. However this is not published because the data is not complete. We aim to report on accurate and reliable information and therefore do not want to release sales volume data that has the potential to be misleading if quoted out of context.
Details of repossession sales are only available for England and Wales.
In August 2016, we began reporting on Repossession data for England and Wales for the month of April 2016.
For England, this is volumes of repossessions recorded by Government Office Region shown as a table and in a heat map. The data is also available to download as a .csv file.
For Wales, there is a headline figure for the number of repossessions recorded in Wales. This data is also included in the .csv file.
6. The difference between the UK HPI and others
Currently, there are a number of different sources of house price statistics published in addition to the UK HPI. There will be differences in the data published by each source, as there are differences in both the data and methodology used. For example, Rightmove use asking prices, sources such as Nationwide and Halifax use their own mortgage approvals data, while the UK HPI uses data at the end of the conveyancing process, calculated based on completed sales.
Find our more about the difference between the various house price index measures and their strengths and limitations in our publication Comparing house price indices in the UK.
High level summary
The UK HPI is calculated based on completed sales at the end of the conveyancing process. This means that while the UK HPI may not be as timely in publishing as the other measures, it is however ultimately more complete with coverage of both cash and mortgage transactions for the whole of the UK. The large data source used, land registrations (such as that maintained by HM Land Registry), allows data to be published down to a local authority level with further breakdowns available by property type, buyer status, funding status and property status.
Halifax house price index and Nationwide house price index
Both Halifax and Nationwide produce house price indices based on their own mortgage approvals only and therefore will not include any cash transactions. They both have UK-wide coverage, and since the Halifax and Nationwide use only their own in-house data they can process them immediately and do not have to await the receipt of data from other lenders. This means that they are timelier than the UK HPI.
LSL Acadata house price index
Similar to the UK HPI in data source. LSL Acadata (previously the LSL Property Services/Acadametrics) HPI is based on completed sales at the end of the conveyancing process using data from HM Land Registry for England and Wales. The HPI provides mix and seasonally adjusted results at national, regional and county or unitary district or London borough levels.
The index can be accessed at Acadata.
Rightmove house price index
The Rightmove index includes all property types that are advertised on its website. However it includes houses that do not subsequently sell and reports only asking prices. If house price movements are different between the non-selling and selling houses then this will affect the accuracy of estimates of house prices and changes in them.
Registers of Scotland official quarterly housing market statistics
Registers of Scotland will continue to produce average house prices based on arithmetic means of these transactions, which is published as the quarterly housing market statistics in the second month after the month to which the figures refer to.
House Price Statistics for Small Areas
House Price Statistics for Small Areas (HPSSAs) are published on a quarterly basis calculated based on HM Land Registry Price Paid data. HPSSA’s are not a house price index as they do not control for changes in the mix of properties over time (mix adjust), therefore they provide different figures to the UK HPI. They report non-adjusted average transaction values down to middle super output area.
7. Republishing data
UK HPI data is published under Open Government Licence. When using or publishing data from the UK HPI reports, background tables in the statistical datatset: UK House Price Index: data downloads: data downloads or search tool, you will need to add the following attribution statement:
Contains HM Land Registry data © Crown copyright and database right 2017. This data is licensed under the Open Government Licence v3.0.
When you publish the data, be sure to include information about the nature of the data and any relevant dates for the period of time covered.
Neither HM Land Registry nor any third party shall be liable for any loss or damage, direct, indirect or consequential, arising from:
- any inaccuracy or incompleteness of the data in the UK HPI
- any decision made or action taken in reliance upon the data
Neither shall HM Land Registry or any third party be liable for loss of business resources, lost profits or any punitive indirect, consequential, special or similar damages whatsoever, whether in contract or tort or otherwise, even if advised of the possibility of such damages being incurred.
8. Data tables
When the UK HPI data tables are published each month, they represent our best available view on historic house price movements at the time. As new information becomes available, the tables are revised to reflect any new data. Each month the new data will be added and the previous 12 months updated to reflect any additional sales added for those months.
As the NI House Price Index is published quarterly and sales data form the basis of future domestic revaluations, the NI price data series will be revised as and when necessary to take account of any new sales information received, therefore the most recently published data series from Jan 2005 should be used NI House Price Index from Q1 2005.
8.1 How this data is different to data available from the ‘Search the House Price Index’ tool
The Search the UK House Price Index tool allows customers to produce printable reports derived from the House Price Index data. The reports can also be downloaded in CSV ‘on UK House Price Index data downloads, or Turtle formats, and the SPARQL query generated in the background view. Real-time previews allow search options covering average prices, indices, sales volumes and property types ranging from January 1995 to the most recent available data to be changed easily.
The House Price Index data tables are for customers that would like to download the full dataset in a more usable format which incorporates data behind the UK House Price Index.
The tables are made up of:
- UK HPI full file
- Average price
- Average price by property type
- Cash mortgage sales
- First time buyer and former owner occupier
- New build and existing resold property
- Index seasonally adjusted
- Average Price seasonally adjusted
The following files are also available detailing revisions to data published in the previous 12 months:
- UK revisions
- England revisions
- Wales revisions
- Scotland revisions
- Northern Ireland revisions

8.3 How to access the data
UK HPI data is published monthly in CSV and linked data formats on data.gov.
8.4 Seasonal adjustment
The difference between the tables called Index and Index (Seasonally Adjusted):
- the Index table contains monthly residential property price index at regional, county/unitary authority and London borough level.
- the Index (SA) table contains seasonally adjusted monthly residential property price indices at regional and national level.
8.5 Monthly change and annual change
Data presented in the Monthly Change and Annual Change tables:
- the Monthly Change table contains monthly change figures which represent the month-to-month percentage change of the index.
- the Annual Change table contains annual change figures. These represent the percentage change in the index over the last 12 months.
8.6 Sales volumes table
This table contains counts of all sales included in the electronic register at the time of data extraction. The data collection delay mainly affects the most recent months. The two most recent months are therefore omitted from this data to avoid reporting misleading volumes.
Sales volume data is also available by property status (new build and existing property) and funding status (cash and mortgage) in our downloadable data tables. Transactions involving the creation of a new register, such as new builds, are more complex and require more time to process. Read Revisions to the UK HPI data for more information.
As we are not able to identify the funding status of every property transaction sales volumes for cash/mortgage may not equal the total.
8.7 Levels at which the data is presented
The data presentation is in:
- ‘Monthly Change’
- ‘Annual Change’
- ‘Average Prices’
- ‘Sales Volumes’ are provided at national, regional, county/unitary authority, local authority and London borough level
Data in ’Average Prices (SA)’ and ‘Index (SA)’ tables are presented at national and regional level.
