London house prices: UK’s 10 most expensive streets are all in the capital

The average house price on the UK’s most expensive street is £20.35 million, almost 72 times the £283,615 average cost of a home in across the country.

According to a list by Halifax, based on data as of December 21 2023, the 10 most expensive streets in the country are all in London, with Grosvenor Square in Mayfair taking the top spot.

Grosvenor Square has been home to British aristocracy since the 1700s and housed the US Embassy until 2017. A young JFK lived on the square when his father was US ambassador to London, and it is believed it was also once home to Oscar Wilde.

Heading west to the borough of Kensington and Chelsea, Clarendon Road in Notting Hill took second place with an average price tag just shy of the £20 million mark, at £19.96 million. 

Making up the top three – and home to world-famous luxury shopping destination Harrods – is London’s Knightsbridge, where properties cost an average £19.95 million.

The most expensive street outside the capital is East Road, in Weybridge, where an average home will set buyers back over £9 million

Kim Kinnaird, mortgages director Halifax, said: “Buying any home is expensive and likely to be the biggest single purchase most people will ever make.

“Purchasing a property on one of Britain’s most expensive streets comes with a colossal price tag and it’ll be no surprise that house prices in London continue to dominate, with the top 10 priciest streets to buy a home all in the capital. But the gap between the most expensive streets is vast, depending on the region you live in, with the average house price for the priciest properties in London topping £20 million, compared to around £1.3 million in the North East. 

“Even in the most expensive region outside of London, the South East, the top 10 most expensive streets are, on average, £10 million cheaper than their London equivalents.”
