The Office for Statistics Regulation has designated the UK House Price Index as a National Statistic. A letter from the Director General for Regulation details the actions that were taken to meet the requirements as set out in the UK HPI assessment report.
House price inflation is the rate at which the prices of residential properties purchased in the UK rise and fall. 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 price changes in the most recent periods as they can be revised. Further information is provided in our revision policy.Back to table of contents
Average house prices in the UK have increased by 3.2% in the year to August 2018 (down from 3.4% in July 2018), remaining broadly stable at a national level since April 2018 (Figure 1).
Over the past two years, there has been a slowdown in UK house price growth, driven mainly by a slowdown in the south and east of England. The lowest annual growth was in London, where prices decreased by 0.2% over the year, down from being unchanged (0.0%) in the year to July 2018.
The average UK house price was £233,000 in August 2018. This is £7,000 higher than in August 2017 and £1,000 higher than last month (Figure 2). On a non-seasonally adjusted basis, average house prices in the UK increased by 0.2% between July 2018 and August 2018, compared with an increase of 0.5% in average prices during the same period a year earlier (July 2017 and August 2017). On a seasonally adjusted basis, average house prices in the UK increased by 0.3% between July 2018 and August 2018 (series available in data downloads).

House prices in the south and east of England increased by 1.6% in the year to August 2018, compared with growth of 5.8% in the midlands and 3.4% in the north of England. While the annual growth rates of the midlands and the north of England have remained broadly stable over the past two years, the south and east of England has witnessed a sustained slowdown.
At a regional level, the East Midlands showed the highest annual growth, with prices increasing by 6.5% in the year to August 2018. This was followed by the West Midlands (5.1%) and Yorkshire and The Humber (3.7%).
The English regions with the slowest annual growth were all in the south and east, with the lowest being in London, where prices decreased by 0.2% over the year.
While the annual house price growth in the south and east of England is slowing, they remain the most expensive areas to purchase a property. London is the region with the highest average house price at £486,000, followed by the South East and the East of England, at £329,000 and £292,000 respectively. The lowest average price continued to be in the North East at £134,000.
