AcadHPI is the only UK house price index based upon every residential property transaction in England and Wales and is designed to provide a “true measure of house price inflation”. AcadHPI has been chosen by the Chicago Mercantile Exchange, the world's largest derivative exchange, for their proposed residential house price derivative which we expect will be launched once the current falls in house prices can be seen nearing an end.

Our unique test as to whether indices provide a “true measure” is explained in our “Index Monitor” paper.

The series of downloadable documents provided below includes our latest news release and full historic data series. The significant differences which can arise between indices based upon mortgage offers and those based upon final transaction prices are particularly in evidence in the results this year.

A history of our index is provided in "Why an AcadHPI?".

AcadHPI was launched in September 2003 under the name AcadHPI; it is now released by Acadametrics for publication on the Friday preceding the second Saturday of every month.

This is the ninth month in succession in which AcadHPI has increased on a monthly basis. Annual price increase is 5.4% On an annual basis, in January, the average price of all residential property transactions in England & Wales was 5.4% higher than a year ago - a significant market recovery. It is the third consecutive month in which the annual rate of change in house prices is positive. December transactions are the highest for two years, helped by the stamp duty holiday This was a strong end to 2009 which had seen the lowest number of annual housing transactions in England and Wales since the Land Registry began computerising its records in 1995. The market in December was assisted by an increase in the sale of properties valued below £175,000, with purchasers seeking to take advantage of the stamp duty holiday which ended on 31 December 2009.
