2. Things you need to know about this release

On 15 June 2017, the National Statistician announced that pre-release access to ONS statistics will stop with effect from 1 July 2017.

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. These departments will continue to work together to produce the release but ministers and those officials not directly involved in the production and release of statistics will not have access to them in advance of publication.

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 prices changes in the most recent periods as they are liable to be revised. Since 13 June 2017, we have extended our revision period to 12 months. Further information is provided in our revision policy.

The UK HPI has been published initially as an experimental official statistic to:

  • allow for users to acclimatise to the format of the new HPI
  • evaluate user reaction to the new data
  • continue evolution of data publication to meet user requirements
  • further develop the data sources used in the production

Further information on the process we’re following to remove the Experimental Statistics status can be found in About the UK House Price Index.

6. House price index, by UK local authority district

The local authority showing the largest annual growth in the year to August 2017 was Wellingborough, where prices increased by 15.3% to stand at £215,000. Low numbers of sales transactions in some local authorities and London boroughs, such as the Shetland Islands and City of London can lead to volatility in the series. Whilst efforts are made to account for this volatility, the change in price in these local levels can be influenced by the type and number of properties sold in any given period. The lowest annual growth was recorded in Aberdeenshire, where prices fell by 5.7% to stand at £189,000.

In August 2017, the most expensive borough to live in was Kensington and Chelsea, where the cost of an average house was £1.2 million. In contrast, the cheapest area to purchase a property was Blaenau Gwent, where an average house cost £82,000.

Full details on data at the local authority level can be found in the main publication of the House Price Index.
