Almost half a million people in Britain now own properties worth over £1m, it is being claimed this morning.

The figure of 484,081 is up 49% on last year, according to Zoopla.

The portal also says that there are 10,613 streets with an average property value of £1m or over.

The number includes 12 streets, all in London, where average house prices are over £10m.

Outside London, Virginia Water (hello, James Wyatt) is the most expensive place with property values at £1.19m. In seventh place, in the part of the world known as Trevor Kentdom, is Gerrards Cross, Bucks, at £836,434.

Richmond, Ascot, Guildord, Leatherhead, Mitcham, Woking, Esher, Sevenoaks and Farnham also do pretty well – at least for those who already own the property and are not aspiring first-time buyers earning the average wage of £26,500.
