The ONS House Price Index (HPI), previously published by the Department for Communities and Local Government (DCLG) is a monthly release that publishes figures for mix-adjusted average house prices and house price indices for the UK and its component countries and regions. The index is calculated using mortgage financed transactions that are collected via the Regulated Mortgage Survey by the Council of Mortgage Lenders. These cover the majority of mortgage lenders in the UK.
The HPI statistical bulletin provides comprehensive information on the change in house prices on a monthly and annual basis. It also includes analysis by country, region, type of buyer (first-time buyers and former owner-occupiers) and type of dwelling (new dwelling or pre-owned dwelling). Historical series for all accompanying tables are also available in the data section of this release.
ONS has published Official House Price Statistics Explained, a guidance document that details the ONS HPI methodology and explains the differences between the different sources of official house price statistics.
New this month
New house price data for July 2013 are published this month. The monthly and quarterly reference table (3.32 Mb Excel sheet) has been updated to include data for July 2013.
Revisions this month
There are small revisions to all the seasonally adjusted series from the beginning of these series in February 2002. These revisions are implemented once a year following the seasonal adjustment review of the ONS HPI and ensure higher accuracy of all the seasonally adjusted series. This review identified seasonality in the new dwellings index, and therefore this series will be published seasonally adjusted from now onwards.
Revisions next month
No revisions are expected for the August 2013 HPI, apart from the normal revisions to the latest 12 months that follow the monthly seasonal adjustment process.
Taking forward the recommendations from the National Statistician’s review of UK house price statistics
Following the publication of the National Statisticians review of house price statistics in 2010, the current producers of official house price statistics have been in consultation regarding how best to take forward the review recommendations.
Following initial discussions, it was agreed that the current ONS HPI would be developed to become the measure that best meets the user requirements laid out in the 2010 review, mainly by expanding the coverage of the index to include cash sales data. The inclusion of cash sales would be carried out by using Land Registry data to supplement the current ONS dataset.
Analysis has shown that this proposed development would not meet the recommendations laid out in the review, namely the development of a joint, single definitive UK house price index as, under this approach, each of the current departments would continue to produce their own indices in their current format leading to confusion for users.
Therefore, following agreement across the four producers of official house price statistics, it is proposed that a joint project is initiated to consider the development of a single definitive UK House Price Index from which official providers can report on their own areas of responsibility in a way that can be directly compared. This collaborative approach would allow the publishing of consistent HPI data at a national, regional and sub-regional level across the UK.
The first stage of this development is to consider how the current data sources and methodologies can be used to produce a single, definitive HPI that meets user requirements. It is expected that this initial analysis will take approximately three to four months at which time a more substantial note on the plans, methods and timetable for the implementation of the index will be published. This note was first published in the May 2013 HPI.
Index of Private Housing Rental Prices
On 26 June 2013 ONS published the Index of Private Housing Rental Prices (IPHRP). IPHRP is an experimental series that measures the changes in price charged for renting private housing in Great Britain. The index is calculated from rental prices collected by Valuation Office Agency, Scottish Government and Welsh Government, and includes price indices at country level and English region level. The next publication of the IPHRP is scheduled for 25 September 2013.
ONS HPI monthly and quarterly reference tables (3.32 Mb Excel sheet) (number 1 to 19). This reference table provides full historical series for the monthly tables accompanying the House Price Index statistical bulletin. This month, tables 1 to 9 have been updated with the latest monthly data for July 2013. Following the annual review of the HPI seasonal adjustment process, the seasonally adjusted figures in Table 7 have been revised. The revisions affect the entire series to their beginning in February 2002. Following the latest review the new dwellings series has been identified as being seasonal and therefore is now seasonally adjusted. This reference table also contains all the quarterly live tables transferred to ONS from DCLG. Please note that during the transfer ONS renumbered the live tables. Full details of the new table numbers and their corresponding DCLG table numbers can be found in the 'contents' page of the reference table.
ONS HPI annual tables (1.16 Mb Excel sheet) (number 20 to 39). This reference table contains all the annual live tables transferred to ONS from DCLG. No annual tables have been updated this month. The next scheduled update of this table is March 2014.
