Data has been freely released giving access to Energy Performance Certificates for homes built, sold or let since 2008 – and it could prove useful to agents and valuers.
The Energy Performance Certificates information gives the floor areas of the properties which, if cross-referenced with house price data, yields the average price per square foot in any particular area.
Neil Hudson, director of Residential Analysts and previously associate director in the research department at Savills, has made full use of the data sets.
He has created a map of London showing, by colour coding, the range of prices per square foot – anything from below £300 (almost impossible to spot on his map but at any rate on the peripheries of the city), to the white heat of £1,000 spread over a surprisingly large area in central London.
