However, in an extraordinary reversal of fortunes for the homeowners of west London, house prices started falling in Kensington and Chelsea last year, and are now down by as much as 13 per cent. Some analysts are expecting prices to fall by the same amount again this year.

Dropping Chelsea house prices are hardly a barometer for what is happening across the country, however.
