The Reform UK Treasurer just sold his Chelsea mansion for £275 million – making it London’s most expensive house sale ever
Property developer and Reform UK treasurer Nick Candy has sold his lavish Chelsea mansion, Providence House, for more than £275 million, the Financial Times reports.
The sale has also been confirmed by Bloomberg.
The transaction eclipses previous high-end sales in the capital, including the £139 million sale of The Holme in Regent’s Park in 2024 and the £200 million-plus deal for a 45-room mansion at 2-8a Rutland Gate in 2020. It ranks among the world’s most expensive residential property deals.
The buyer’s identity remains unknown. UK Sotheby’s International Realty was involved in the transaction but declined to comment. The property had never been formally marketed for sale, with prospective buyers approaching Candy directly over the years.
One agent told the Financial Times that “any big buyer in the market over the past few years has knocked on his door,” with various figures discussed.
Providence House (formerly known as Gordon House) sits on the grounds of the Royal Hospital Chelsea. Christian Candy, Nick’s brother and business partner, purchased it in 2012 for around £75 million before transferring ownership to Nick two years later.
Visitors have described the Grade II-listed home as featuring a private cinema complete with a “Candy bar” pick ’n’ mix station, an underground swimming pool, an orangery, and a panic room. The large brick building with bay windows overlooks well-kept gardens and trees.
Nick Candy rose to prominence alongside his brother Christian as the driving force behind One Hyde Park, the ultra-luxury Knightsbridge apartment complex that has attracted oligarchs, pop stars, and billionaires.
The development epitomises London’s super-prime market, though it has also drawn scrutiny for its association with secretive wealth.
Candy recently listed a five-bedroom, eight-bathroom duplex penthouse in One Hyde Park with an asking price of £175 million. The property boasts uninterrupted views over Hyde Park, wraparound terraces, and Jacuzzi-style jet pools. It carries an outstanding mortgage originally exceeding £80 million, according to related filings.
A former major donor to the Conservative Party, Candy joined Nigel Farage’s Reform UK last year as Treasurer.
He has focused on transforming the party’s finances, organising fundraising dinners that have drawn former Tory donors, and was present at a December meeting at Donald Trump’s Mar-a-Lago resort involving Farage and Elon Musk.
The sale comes amid a selective ultra-prime segment in London. While overall sales of homes above £5 million dipped in 2025, trophy properties continue to command eye-watering sums when the right buyer appears.
Another notable listing is shipping magnate John Fredriksen’s Chelsea mansion, which has been on the market with discussions around £275 million.
