West London's most expensive postcode has an average price of more than £6m, it has been revealed.
Homes in W1K 3, between Berkeley Square and Grosvenor Square, in Westminster, had a median selling price of £6.2m in 2014, with five sales in the postcode. This was an increase of 67.6% from a median selling price of £3.7m in 2013.
There were 80 other £1m postcodes in west London, including W1K 1 near Park Lane, where one home sold for £15.9m, and SW1P 2 near Vincent Square in Pimlico, where the median price of 157 properties sales was £1.25m.
WC2H 0, near Charing Cross Road, has seen the biggest year-on-year increase in prices in the country, with prices increasing more than fivefold from a median of £425,000 in 2013 to £2.28m in 2014 - probably due to the building of luxury apartments on the former site of Central Saint Martins.
The biggest drop was in SW1X 7, in Knightsbridge and Belgravia, where median prices more than halved in a year, from £4.8m to £2.1m.
The comparisons are based on property sales registered with the Land Registry in 2013 and 2014.
The Land Registry lists the price paid for every property bought at market value by non-commercial buyers, so auction sales and property bought through companies is excluded.
It is based on median price paid in an area, which hopefully prevents one really expensive property skewing a lower average. It will mean that an average can seem quite low if the area is mixed so has a range of more expensive and less expensive houses.
The comparison isn't adjusted to take into account the type of houses sold - so if one year sees lots of flats sold in an area and then the next year sees lots of detached houses sold, it's going to show as a big change in median price paid.
