Halifax has revealed the UK’s most expensive streets, with Grosvenor Square in the London borough of Westminster now topping the list. 

Average house prices in the area, which sits at the heart of Mayfair, will set buyers back a jaw dropping £20.35 million. Grosvenor Square is one of the largest squares of its kind in London, with a rich history which can be traced to the early 18th century. 

Heading west to the borough of Kensington and Chelsea in cosmopolitan Notting Hill, Clarendon Road takes second spot with an average price tag just shy of the £20 million mark, at £19.96m. Making up the top three – and home to world-famous luxury shopping destination Harrods – is London’s Knightsbridge, where properties now cost an average £19.95 million. 


If a home on one of London’ priciest streets is top of the Christmas list this year, deep pockets will be needed, with the average price tag now £14.5 million.

With the average UK house price now £283,615* the costliest properties in the country are almost 72 times more expensive than a typical home.

The most expensive street outside of the capital is East Road, in Weybridge, where an average home will set buyers back over £9m. For a relative bargain, the priciest residences in Wales start from £1.3m.

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 ten 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 £20million, compared to around £1.3m in the North East. 

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