House prices actually increased by 0.2% in the capital between February and March and fell in every other English region.
This was equivalent to an additional £818 added to the value of the average residential property in London over the month.
In fact, house prices in London have fallen in only four of the last 12 months.
Robert Bartlett, Chesterton Humberts CEO, said: "What also sets London out from the rest of the crowd is the fact that house prices were higher in March 2011 than they were in March 2010.
"Over the year, house prices in London have risen by 2.2%, compared to a comparatively steep annual decline throughout the rest of the country.
"The typical price of a house in London (£338,583) is -3.9% below the highest ever price recorded for the capital as a whole."
