Biography
Gary Hersham is a British estate agent and the founder of Beauchamp Estates, a London agency specialising in prime and ultra-prime residential property. He has worked in the London property market for more than four decades and is closely associated with some of the most expensive private home sales recorded in the United Kingdom, including the sale of a mansion on Rutland Gate in Knightsbridge for around £210 million.
Founding Beauchamp Estates
Hersham founded Beauchamp Estates in 1979. The firm's head office is on Curzon Street in Mayfair, and it has since opened further London offices, including in St John's Wood and Marylebone. Over time the agency has extended its reach beyond London, with offices or associate offices in Cannes, St Tropez, Mykonos, Tel Aviv, New York and Los Angeles. Its client base is international, and the firm works with buyers and sellers from Europe, the Middle East, Asia and North America.
Trade press accounts of his early career describe an agent who built the business from the ground up. In an interview with The Negotiator, he recalled letting a Belgravia house to a senior member of a Middle Eastern royal family in the firm's early years and carrying the deposit and first month's rent back to the office by bus, as he did not yet own a car.
Notable transactions
Hersham's name is most often linked to the sale of 2-8a Rutland Gate, a 45-room mansion in Knightsbridge. The sale, completed in 2020, was widely reported as the most expensive home ever sold in Britain at the time, exceeding the previous UK record of £140 million. According to the firm's own published account, Beauchamp sold the house on behalf of a member of the Saudi royal family to a Hong Kong buyer. In the same period the agency also sold a London flat for £50 million to a buyer from Hong Kong.
Other instructions handled by the firm include 93 Eaton Square in Belgravia, a former London home of the prime ministers Stanley Baldwin and Margaret Thatcher, which Beauchamp sold for £21 million on behalf of the estate of Mrs Henry Ford II. The agency has also marketed the Beverly House in Los Angeles, once owned by William Randolph Hearst, and has acted on properties formerly owned by public figures including Robbie Williams, Harold Pinter and Sting.
Publications and recognition
In 2022 Hersham published Anthology, a 121-page hardback book recording the histories of some of Beauchamp's best-known ultra-prime instructions, including homes valued between £20 million and more than £200 million. He has also written commentary for the property trade publication PrimeResi, including a 2019 article titled "The Art of the Mega-Deal" and a 2022 piece on the effect of sanctions on Russian investment in London property.
In 2024 Hersham received a Lifetime Achievement Award from the property data consultancy LonRes, which described him as a giant of the sector. He is listed in the Spear's 500 index of property brokers, where he is ranked in the Top Flight category for 2026, and the publication notes that he is one of relatively few brokers with eight-figure deals attributed to them.
On Wealth Office
Gary Hersham appeared on Wealth Office X in the episode "The Agents Selling $300m Homes In London", published in August 2026, alongside the adviser Irina Gamagina and the host Michael Macfarlane. Asked where he would spend $100 million on a home, he chose London and prime Belgravia in particular, linking London's renewed appeal as a safe haven to conflict in the Middle East and a sense of insecurity in the Gulf. He questioned how much business really happens through private pocket listings, explained how stamp duty, ownership structures and price discipline buyers who first fall for a property emotionally, and observed that buyers at the very top of the market now tend to avoid competing with one another. The conversation also traced how London's buyer base has shifted over the decades and considered emerging prime markets such as Madrid and Milan.
