Britain has nearly 1,800 more £1m streets 

All of the top ten most expensive properties in the country are based in London, with Courtenay Avenue in Highgate in second place with an average property value of £19.4m. Grosvenor Crescent in Belgravia, meanwhile, ranks in third place with an average property price of £17.2m.

Commenting on the research, Zoopla’s head of research Grainne Gilmore, said: “This data illustrates how the type and size of properties coupled with some of the most desirable locations around the country create prime areas, resulting in some of the most valuable residential streets in the country.

“London comes top when it comes to the UK’s prime markets, but the wider commuter zone in the south east is able home to some of the highest-value addresses, reflecting the size and the type of housing stock in these regions.”

Titlarks Hill in Ascot, Berkshire, has been crowned the most expensive street outside London, with an average property value of £8.4m, with Montrose Gardens in Leatherhead, Surrey, being in second place.

Outside of London, Guildford in Surrey is the postal town with the most expensive streets with 176, this is followed by Reading with 137 and Sevenoaks with 133.

In addition to this, regional analysis shows that, of the 11,673 streets with an average property price of £1m and above, 4,544 are found in London, and 4,336 are concentrated in the south east. By contrast, only nine are found in Wales, 41 in the north east of England, and 55 in Yorkshire and the Humber.

There’s also been a 1,782 increase in the number of £1m plus between September 2020 and September 2021.
