When it comes to property, Britain has no shortage of eye-wateringly expensive addresses. From sprawling countryside estates to high-rise penthouses overlooking the Thames, the asking prices of some of the UK’s most expensive homes seem to have spun out of control, with not even a lottery win enough to buy you a home on Britain’s most expensive streets.
While London is known for extortionate house prices, one particular street has stood out for pricing out even multi-millionaires — you’d need to pay more than £20 million on average. It’s a level of wealth so extreme it has understandably been nicknamed “Billionaires’ Row.” According to figures from Lloyds Bank, the most expensive street in the UK is none other than Knightsbridge (SW1X) in central London, where the average house price was a staggering £21,409,000 at the close of 2024. The data refers to the street, Knightsbridge, which of course also gives its name to the area immediately around it.
While there’s no denying these homes are stunning and in one of London’s most affluent and desirable areas, they are still located at the heart of central London, which means for £21 million, they come on the small side.
For many, the wider Knightsbridge area is synonymous with luxury. It neighbours Hyde Park, Chelsea, Belgravia and South Kensington, and it’s home to iconic names like Harrods and Harvey Nichols shops that are frequented by a certain clientele.
Many of the houses that line this particular street are Grade II-listed Georgian townhouses with grand marble facades that scream money. But another reason for driving the prices so high is scarcity.
Large luxury houses in central London are extremely rare, and when they do come on the market, once in a blue moon, many of the wealthiest from around the world come sniffing and are prepared to reach deep into their pockets.
But while these numbers may leave you astonished, when it’s put in line with the rest of the UK, it makes it even more staggering. Across England and Wales, the average house price during the same period (September 2019 to August 2024) was around £356,925.
That makes Knightsbridge homes nearly 60 times more expensive than the typical property. But it’s not just Knightsbridge. Addresses in Ilchester Place, just a few miles away in Kensington, average £19.4 million, followed by Grosvenor Square in Mayfair at about £19.06 million.
Meanwhile, the rest of the top 10 priciest streets are all taken up by London postcodes and all straddle the same four or five square miles.
And, of course, to even appear on the list, some sales will have taken place and there will be other streets in London where a home will set you back well over £21 million, like Kensington Palace Gardens, where the likes of Roman Abramovich and Tamara Ecclestone have bought homes. In 2015, a home there was put up for sale for £85 million and in 2004 it was said to have been home to the world’d most expensive house, when it was sold for £70 million.
Amanda Bryden, head of mortgages at Lloyds, said: “London’s dominance in the list of priciest streets underscores the city’s continued appeal and the resulting competitiveness at the very top end of the property market.
“However, at £21.4 million to buy a home, even those with the deepest pockets might baulk at the price. The cost of securing a prestigious address does vary across the country.
“For instance, living on the most expensive street in Wales means paying around £1.3 million, although still a significant amount.”
