London ultra-luxury property price cuts and sales slowdown

London’s ultra-luxury listings are being cut by millions and taking far longer to sell, reflecting a broader slowdown in high-end transactions. The listing price of a west London flat at Queen's Gate Gardens dropped by nearly £1 million to £4.4 million. A nearby house originally listed at £20 million was slashed to £14 million this year. Dozens of mansions and penthouses across London are having their prices slashed by millions as they struggle to sell.

High-end property prices in London's swankiest postcodes have plummeted. Data from the Office for National Statistics in August showed some properties have lost more than a quarter of their value in just the last year. The typical property over the last quarter achieved 6.6 per cent below its initial asking price, up from a 6.3 per cent discount a year earlier.

Owners who bought at the peak face losses of up to 25% if they sell. The estate agent Strutt & Parker downgraded its forecast for prime central London price growth to 4.4% by 2030, down from 9% to 12% at the start of the year.

Transaction volume shifts

While overall transaction volumes are falling, deals in the £10m-£20m bracket have risen sharply in recent quarters. Transactions in the £10 million or more bracket climbed 50% in the three months ended in June 2026 compared to the same quarter in 2025. Transactions in the £15 million to £20 million bracket rose by almost 40% in the second quarter of 2026 compared to last year.

Rental shift among ultra-prime buyers

A majority of ultra-prime clients are now opting to rent rather than purchase. Seven out of 10 of Beauchamp's ultra-prime clients are choosing to rent rather than buy. Prices in the super-expensive tenancy market, defined as at least £5,000 a week, were up 17% last year.

Regulatory and financing pressures

New tax proposals, higher mortgage rates and reduced foreign buyer interest are driving price cuts and longer listing periods. The former chancellor Rachel Reeves announced plans for a 'mansion tax' on homes worth more than £2 million. Mortgage rates have risen sharply since 2022 from around 1.5 per cent to 5 to 6 per cent now.

Foreign buyers have flooded away from the capital following years of tax changes, including the abolition of the 'non-dom' tax status in 2025. A buyer looking to purchase a £10 million house in 2022 on a 1.5 per cent mortgage would have expected to pay £39,992 every month. With current mortgage rates, the mortgage payment for a £10 million house would be 46 per cent higher at £58,480 per month.

Prime properties spent an average of 186 days on the market in the first half of 2026, up from 178 days in the first half of 2025. The average discount to asking price widened from 8.3% to 10.4% over the same period. Anthony Payne noted, "London benefited dramatically from international investment and buyers wanting property here as a store of wealth and a way of making money."

Britain's richest plumber, Charlie Mullins, dropped the price of his luxury Thames-side three-bedroom apartment by £3 million to £9 million. He bought the apartment for £10 million in 2021. A luxury flat in Principal Tower in Shoreditch, listed for £9.9 million last year, is now available for £7.2 million, a drop of 27 per cent. It has been on the market since October 2025.

A flat in St George Wharf Tower in Vauxhall has been on the market for five years, with its price slashed by more than £3 million from £9.9 million to £6.5 million. This represents a 34 per cent loss in value from its initial listing in March 2021. One seven-bed Grade II-listed house in St John's Wood has seen its list price fall from £17 million to £10 million. It features a swimming pool, a garden and a gated driveway with parking for seven cars. The house has been on the market since December 2025, significantly longer than the UK average of 38 days.
