Nearly 93,000 more home-owners have become "property millionaires" in Britain over the last year, research from a website has found.
The total number of homes valued at £1 million plus by Zoopla.co.uk this month has grown by almost one third (31%) compared with a year ago to reach 393,127.
Zoopla said that continued strong demand for prime residential property throughout 2013 has created 92,985 more property millionaires in Britain over the past 12 months.
Three-fifths (61%) of million pound plus properties were found to be in London. Property prices in the English capital have consistently surged ahead of the rest of the country this year, prompting some concerns that the market there is overheating.
The Government recently announced plans for non-UK residents to pay capital gains tax (CGT) on property sales from April 2015. Much of the strong demand in the London market has been put down to wealthy overseas buyers looking for a safe haven to put their cash.
The exclusive borough of Kensington and Chelsea was named by Zoopla as home to the highest number of property millionaires totalling 41,393.
On a regional level, Wales was found to be home to the fewest property millionaires in Britain, numbering just over 1,000 in total but still up by one quarter (24%) on 2012.
Lawrence Hall of Zoopla.co.uk said: "While Government schemes such as Help to Buy have concentrated popular attention on the lower rungs of the property ladder this year, there's been a hive of activity propelling house price growth at the top-end of the market."
