Eaton Square in London's Belgravia district has been crowned the most expensive street across England and Wales - with the average home there commanding nearly £17 million.
While the wealthiest streets are clustered in central London, every region contains "million pound" streets, where homes are worth six-figure sums typically, Lloyds Bank found.
The average home in Eaton Square is worth £16,944,000, Lloyds found. Built in the 19th century and arranged around private gardens, Eaton Square contains grand houses and apartments behind white stucco facades. Knightsbridge and Chelsea are handily located nearby, as is Buckingham Palace.
Located near Eaton Square, Grosvenor Crescent was found to be the second-most expensive street, with the average property there worth £16,918,000.
Andrew Mason, mortgage director at Lloyds Bank, said: "Eaton Square, and prime central locations such as Westminster, and Kensington and Chelsea, have established reputations as exclusive addresses.
"Not only do these streets possess a rich historical legacy, but properties located there are some of the most prestigious in the world and are close to superb local amenities in Knightsbridge, Sloane Street and Chelsea, as well as the capital's business and entertainment districts."
Away from London, streets located in the Surrey towns of Weybridge and Leatherhead also appeared in the list of the 20 most expensive streets, as did locations in Poole and Oxford.
