London homeowners who bought at the peak of the city’s long property boom are facing an uncomfortable new reality. Their multimillion-pound assets are no longer the reliable wealth machines they once were.
The latest UK House Price Index released on Wednesday (25 March) shows that average house prices in the capital fell 1.7% in the year to January 2026, landing at £554,000. That marks the sharpest annual decline among English regions and contrasts starkly with the modest national picture, where UK prices rose 1.3% to an average of £268,000.
On a monthly basis, London prices dropped 0.8% from December 2025 – the largest monthly fall in England. Flats and maisonettes, which dominate much of the city’s housing stock, were hit hardest, sliding 4.2% year-on-year to £431,000.
A tale of two markets
While northern regions continue to see gains, London and parts of the South East are stagnating or contracting. The South East saw a 0.5% annual drop, and the picture is even more uneven within London itself.
Flats in prime central areas have been particularly vulnerable. Separate analyses from property portals and estate agents indicate that some central London postcodes have seen double-digit declines since 2023, with sellers in expensive neighbourhoods like Kensington and Chelsea, Camden, and Islington reporting losses.
- Cash buyers in London saw prices fall 2.8% annually.
- First-time buyers faced a 2.3% drop, with average properties at £472,000.
- Mortgage-financed purchases declined 1.3%.
: London remains by far the least affordable region in the UK. Even with recent improvements driven by weaker price growth and slightly lower mortgage rates, the average home requires earnings far above typical incomes. First-time buyer earnings in the capital are estimated to be around 45% higher than regional averages just to get on the ladder.
Another major factor is supply. The number of homes for sale in London is up significantly, around 14% higher than a year ago, giving buyers more choice and leverage to negotiate.
Higher stamp duty costs and elevated transaction taxes have made moving expensive, deterring both upsizers and downsizers.
Although rates have eased from their peaks, many homeowners are still sitting on mortgages taken out when borrowing was cheaper. Combined with broader cost-of-living pressures, this has dampened demand. Transaction volumes remain subdued, with UK residential property deals down in January.
For many long-term owners, the numbers look deceptively comfortable on paper. Someone who bought a typical London flat for £300,000 a decade ago might still be up substantially.
But for those who stretched to buy near the 2022-2023 highs, or who are relying on equity release, inheritance planning, or downsizing to fund retirement, the stagnation or outright falls represent a real erosion of wealth.
