Property developer and Reform UK treasurer Nick Candy has sold his Chelsea mansion for more than £270 million.
Believed to be the biggest single house sale in history, Providence House has been sold to an unnamed buyer, with Sotheby’s International Realty leading the transaction.
The home was purchased by Nick’s brother Christian Candy in 2012 for about £75 million, when it was called Gordon House, with ownership transferring to Nick two years later, according to court filings.
The Grade II-listed property is located in the grounds of the Royal Hospital Chelsea, on a two-acre site that once accommodated the residence of Britain’s first Prime Minister Robert Walpole.
Now emulating a grand country estate, Providence House has a lake, swimming pool, and panic room, along with original Georgian details inside the property, and was the location of a fundraising event for Donald Trump in 2024, attended by the US president’s son Donald Trump Jr.
It is believed to be the most expensive ever house sale in UK, if not the world.
The purchase price tops the £210 million paid in 2020 for a 45-room mansion overlooking London’s Hyde Park, and a 40-room property in Regent’s Park which sold for £139 million in 2024.
It also beats the near $240 million sale of a New York penthouse apartment to hedge fund manager Ken Griffin.
Another of Candy’s properties is also on the market, with a five-bedroom, eight-bathroom penthouse in One Hyde Park carrying an asking price of £175 million.
The apartment has an outstanding mortgage owed to the Bank of Singapore, with accounts for another company tied to Candy suggesting the mortgage originally stood at over £80 million.
London’s property market is otherwise suffering from a lull in transactions, with property data firm LonRes reporting that there were 31% fewer sales for prime properties in February than a year before.
Higher property taxes appear to have lessened the demand for London’s priciest homes, with 2025 only the second year since 2011 to not record a sale above £50 million.
Nick and Christian Candy are best known for developing the luxury Knightsbridge apartment block One Hyde Park, which launched in 2011, attracting a number of oligarchs and other billionaire buyers.
Nick Candy was formerly a donor to the Conservatives, but since 2025 has been a senior figure within Reform UK, playing a significant role in fundraising, as well as being a major donor in his own right, having given about £1 million to the party last year.

He is the party’s treasurer, and was at Nigel Farage’s side last year as Reform announced their plan to attract wealthy individuals to the UK with a £250,000 fee for 10 years of residency and a special tax regime.
He was also present at a meeting in December 2024 between Farage and the billionaire Elon Musk at US President Donald Trump’s Mar-a-Lago resort.

Candy previously lived at Providence House with his ex-wife Holly Valance, with the couple announcing their divorce last year.
