Some 11,673 streets in September 2021 had an average property price of £1 million or more, which was 1,782 more than the 9,891 million pound streets in September 2020, Zoopla said.

The South East of England accounts for about half of the increase, with 942 more million pound streets having been created there over the past year, compared with 262 in London.

Kensington Gardens has once again been ranked as the most expensive postcode in the country, with a ridiculous average house price of £29,898,000.

But towards south London, Carlyle Square in SW3 (number 10) ranks highly with an average house price of £9,800,000, as does Manresa Road, also in SW3 (number six) with an average price of £11,181,000.

Grosvenor Crescent, SW1X, near Buckingham Palace (number three) has an average house price of £17,212,000.

The Boltons comes in at number five with £14,223,000.

The tapering of a stamp duty holiday in the summer prompted a rush of buyers snapping up homes. The holiday ended completely from October 1.

Many people have also been searching for bigger properties with more space as they make lifestyle changes as a result of the coronavirus pandemic.

Grainne Gilmore, head of research at Zoopla, said: "London comes top when it comes to the UK's prime markets, but the wider commuter zone in the South East is also home to some of the highest-value addresses, reflecting the size and type of housing stock in these regions."

Excluding London, Titlarks Hill (postcode SL5) in Ascot, Berkshire, was identified as the most expensive street in Britain, with the average home there put at £8.4 million.

Some postal towns outside London also have clusters of million pound streets.

Zoopla counted 176 in Guildford in Surrey, 137 in Reading in Berkshire, 133 in Sevenoaks in Kent, 115 in Harpenden in Hertfordshire, 105 in Altrincham in Greater Manchester and 98 in Henley-on-Thames in Oxfordshire.

This compares with just nine million pound streets found across the whole of Wales.

In total, London recorded 4,544 million pound streets in September 2021.
