Nick Candy, the billionaire developer and treasurer of Reform UK, has shattered records by selling his Chelsea mansion for £270m – the highest price ever achieved for a home in London.

Candy, who was gifted the property in 2014, previously lived there with his wife, Holly Valance. The couple separated last year after 13 years of marriage, marking a personal turning point that now coincides with a landmark deal in the capital’s luxury property market.

The vast 19th-century estate, known as Gordon House, sits within the grounds of the Royal Hospital Chelsea on land once owned by Robert Walpole. Set across two acres, the Grade II-listed mansion blends historic grandeur with modern indulgence, featuring a private lake, underground swimming pool and meticulously preserved Georgian interiors.

Despite never being publicly listed, the trophy home drew intense interest from ultra-wealthy buyers before being acquired for around £270m by an unnamed purchaser, according to Bloomberg, which first reported the sale.

Candy renamed the historic site Providence House after his brother, Christian Candy, gave the house to him as a gift in 2014.

The sale looks to be a remarkable profit for the Candy brothers, with Christian having originally acquired the property for £75m at auction.

The deal marks a huge windfall for the Candy brothers – and a standout moment in an otherwise subdued prime London market, hit by tax rises and the crackdown on non-dom status.

It also comfortably eclipses the previous £210m record, set in 2020 by the family of Hui Ka Yan.

Candy, best known for co-developing One Hyde Park, has increasingly turned his focus to politics, backing Nigel Farage with donations exceeding £1m.

The sale was handled by Sotheby’s International Realty, which declined to comment. Fees are undisclosed, but typical commissions of 1-3% suggest the agency could have earned between £3.2m and £9.7m, including VAT.
