Average prices for prime central London property rose by 0.7% in February and are now up 11.6% over the past 12 months, according to the latest index from Knight Frank.
Prices have risen 43% from their post Lehman collapse low point in March 2009, and are 8.9% higher than their previous peak in March 2008. Volume of sales has risen 85% in the year to February.
The index also reveals that Italians have accounted for 8% of purchases since January, beating Russians to the top spot.
The sustainability of central London's property market has been questioned continually since the current revival began in 2009. But rising sales volumes should provide some comfort according to Liam Bailey, Knight Frank's head of residential research.
