Buying a square metre of Kensington and Chelsea property now costs roughly the same as a new entry-level Ford Fiesta. With one square metre costing £10,854, the area is the most expensive local authority in the country to live in. According to data from Halifax, average house prices in this and six other London boroughs have shot up by more than 50 per cent per square metre since 2009. But while every borough in London has seen an increase, many other areas are still well below the levels they were at five years ago.
This interactive map shows how prices have changed between 2009 and 2014, with the local authorities shown in blue recording price decreases. Data for the regions in grey was not provided.
