Eight in 10 London’s Luxury Homes Sell Below Asking Price as Property Market Faces Deepening Slowdown

London’s prestigious property market is facing mounting pressure as wealthy homeowners increasingly accept substantial discounts to sell their properties, with eight in 10 homes in some of the capital’s most exclusive neighbourhoods now changing hands below their original asking prices.

Research by private bank Coutts found that properties in prime central London, including Mayfair, Belgravia and Knightsbridge, are selling at an average discount of around 10%. Prices in the capital’s luxury property market fell by 5% in the third quarter of 2026 and are now approximately 14% below their 2014 peak.

The slowdown reflects a combination of higher borrowing costs, changing tax policies, economic uncertainty and weakening interest from international buyers. London’s luxury housing market, traditionally supported by wealthy overseas investors seeking long-term assets and prestigious residential addresses, has faced particular challenges following changes to Britain’s non-domiciled tax regime.

The impact has been especially pronounced in some of the city’s most expensive districts. Property values in Knightsbridge are now 30.8% below their previous peak, while Belgravia has recorded a decline of 26.9%, according to Coutts research.

Activity has also weakened. Transactions across prime central London fell by 9.1% in the third quarter compared with the previous quarter, while sales of properties priced between £2 million and £5 million dropped by 22.3%. New property listings declined by 14% quarter-on-quarter, suggesting that uncertainty is affecting both buyers and sellers.

Higher financing costs are adding to the pressure. Although the Bank of England’s base rate remained at 3.75% in the latest reported figures, volatility in financial markets has pushed up swap rates, which influence the cost of fixed-rate mortgages. This has made some buyers more cautious about committing to expensive properties.

However, the market is not experiencing an equally sharp decline at every level. There were 26 property transactions worth more than £10 million during the third quarter, taking the annual total to 127 deals valued at £2.88 billion. This suggests that demand among the wealthiest buyers remains active despite broader market weakness.

The slowdown presents a changing landscape for London’s property investors. Buyers with available capital may find greater negotiating power, while sellers face increasing pressure to adjust their expectations.

Despite the current challenges, London continues to attract international attention because of its financial institutions, educational opportunities and global connections. But restoring confidence in its luxury housing market may depend on greater economic stability, predictable tax policies and improved affordability.

For now, the era of consistently rising prices in London’s most prestigious neighbourhoods appears to have given way to a more cautious market, where buyers hold greater influence and sellers increasingly have to compromise.
