London’s Prime Property Market Faces Deep Price Cuts

Prime-level flats and houses in central London have seen listing prices fall sharply. A west-London flat on Queen’s Gate Gardens is now £4.4 million, nearly £1 million lower than a year ago. A nearby house originally listed at £20 million was reduced to £14 million, and a Notting Hill property that debuted at £16 million is now under £14 million. Across the capital, average prices in inner-London boroughs fell 8.3 % year-on-year, with Westminster down 25.4 %, the City down 20.4 % and Kensington and Chelsea down 14.7 % (ONS).

London’s mid-2010s property boom created an overvalued market. Brexit uncertainty, the Covid-19 pandemic, higher taxes and rising borrowing costs amplified the surge. Recent tax reforms—most notably the abolition of the non-dom regime and proposals for a “mansion tax” on properties over £2 million—have prompted many high-net-worth buyers to exit.

• Discounts: Average discount to asking widened from 8.3 % to 10.4 % in H1 2026.

• Transaction volume: Sales of homes priced at £10 million or more rose 50 % in the three months to June 2026 versus the same period in 2025 (JLL). Transactions in the £15-20 million bracket increased by almost 40 % over the same comparison.

Anthony Payne, chief executive of LonRes, said international investment drove the earlier surge and many investors are now leaving. Stuart Bailey, head of super-prime sales at Knight Frank, noted that discounted properties are dragging the market down but some buyers still pay above asking for “the very best in class” assets. Camilla Dell, a buying agent, reported continued demand from overseas buyers—including Americans, Singaporeans and Nigerians—stating that politics “rarely comes up in conversation.”

The corrections are forcing owners who bought at peaks to accept losses of up to 25 %, reshaping investment strategies among the city’s wealthiest residents. A shift toward renting among ultra-prime clients is tightening the supply of high-end rental stock, while average UK home prices were just under £275,000 in September, underscoring the growing divide between London’s luxury segment and the rest of the country.

Sources agree on the direction of price declines but differ on the magnitude of future tax policy impacts. No concrete timeline or official government statement on the proposed “mansion tax” is provided, leaving uncertainty about how forthcoming legislation may affect the market.
