With central London now affordable only to the super-rich, everyone outside the top 1 per cent who wants to live in the capital is heading further out.
 

And this graphic shows how a ‘middle-class migration’ is seeing affluent buyers leave Kensington and Chelsea in favour of Chiswick and Clapham.

Herne Hill and Kensal Rise are the new ‘nappy valleys’, while well-off couples who cannot afford to live where their parents did are heading to Kilburn.

But with the average house price in the capital now at £460,000, most properties are still out of reach for the majority of buyers on normal incomes.

This map shows how London is now split up – with red showing the central market, blue for the established market, and yellow for the emerging market.
