A property on one of the top 20 most expensive streets in England and Wales will set you back an eye-watering £4.7m to £6.8m pounds. Recent housing market statistics may show that property prices are stagnating or even falling in some areas. But according to analysis of Land Registry data by the property information website mouseprice.net, the credit crunch has not caused values at the very top end of the market to crash. Last year's most expensive street, Kensington Square in London's W8, cost £5,534,480; but a new high has been set by Courtenay Avenue, N6 where the average home costs £6,809,900.

Unsurprisingly, London and the South East account for the majority of streets wth the highest property values across England and Wales; top prices in these two regions are more than double the value of the most expensive streets in some other regions

Wales is the region with the lowest average prices; with the top street reaching £897,400, it is the only region whose top street does not break the million pound mark.
