According to Zoopla's Property Rich List, some 484,081 flats and houses across Britain place homeowners in the millionaire bracket, with addresses across the country's capital topping the league table.

"London boasts all of Britain's 20 priciest addresses. Prime properties in the capital have long been a magnet for the super-wealthy looking for a safe investment asset," said Zoopla's Lawrence Hall.

"For the lucky few who can afford these stratospheric price tags, the fabulous mansions on streets like Kensington Palace Gardens and the Boltons are offering very strong returns.

"However, you don't need to be a billionaire to get a chance to own the crème de la crème of property on offer. In Wales and the North East, you can still snap up a prime property in the region's most desirable streets for little over £1m."

Zoopla's index shows a dramatic rise in property millionaries from 2009, where there were just under 200,000 homes worth a million pounds, compared to the 484,081 flats and houses in this bracket today.

Out of the 10,000 streets where properties are worth at least £1m, 3,744 of these are in London.
