Key Points
- Dramatic Annual Drop: Office for National Statistics (ONS) data revealed that house prices plummeted by 22.8% in Westminster during the 12 months leading up to May, marking the most significant crash across the capital.
- Massive Financial Losses: The steep decline wiped out just over £247,000 from the average property value in Westminster, lowering it from £1,083,519 in May 2025 down to £836,331.
- Sustained Capital-Wide Decline: Property values across London have experienced continuous decreases for nine consecutive months, with the broader annual decline accelerating to 3.7% in the year to May.
- Other Affected Boroughs: Following Westminster, Tower Hamlets recorded the second-largest annual drop at 14.5%, followed by Hammersmith and Fulham at 10.9%, and Kensington and Chelsea at 10.7%.
- Contributing Pressures: Experts attribute the downward spiral to a complex mix of economic and political elements, including higher interest rates, mortgage burdens, prospective tax modifications, and shifting international capital dynamics.
London (Extra London News) July 24, 2026 — House prices have plummeted by more than a fifth in central London over a single year, according to newly released figures from the Office for National Statistics (ONS). The official data outlines a staggering 22.8% plunge in Westminster values throughout the 12 months leading to May, representing by far the most severe downturn experienced across the capital. This steep correction has reduced the average cost of a home in Westminster to £836,331, marking a sharp contrast to the £1,083,519 recorded in May 2025 and effectively evaporating nearly £250,000 from property valuations in the heart of the city.
Why Are Central London House Prices Experiencing A Historic Correction?
The sheer scale of the property devaluation has drawn immediate reaction from financial and real estate analysts monitoring the capital’s shifting economic landscape. As reported by standard journalistic coverage, Russ Mould, investment director at AJ Bell, stated that
“it’s a very substantial correction after a very long run of higher house prices.”
Mould further elaborated on the driving forces behind the trend, noting that
“there is combination of factors ranging from the economic to the political.”
According to financial assessments, these pressures encompass prolonged high interest rates resulting in elevated monthly mortgage payment bills, localized tax policy adjustments, and instances of affluent residents relocating abroad due to a perception that
“their capital is not as welcome in the UK as it once was.”

How Severe Is The Wider Decline Across London Boroughs?
While Westminster experienced the most dramatic erosion of property wealth, the downward momentum has rippled widely across other prime central and inner-London boroughs. ONS figures analyzed by industry reporters show that Tower Hamlets suffered the second-steepest annual drop at 14.5%, trailed closely by Hammersmith and Fulham with a 10.9% decrease, and Kensington and Chelsea seeing values contract by 10.7%.
Overall, the city-wide decline in London house prices gathered pace, accelerating to an annual drop of 3.7% in the year to May, worsening from the 2.3% decrease registered during the 12 months to April. Market statisticians note that house prices across the capital have now registered uninterrupted monthly falls for nine consecutive months, presenting a distinct divergence from national trends where average UK house prices grew by 2.7% over the same 12-month period.
What Future Policy Risks Threaten The Capital’s Property Market?
Industry observers warn that the current correction could be further compounded by upcoming fiscal and structural policy shifts targeting high-value real estate.
Property analysts indicate that the drops in central London may have been accelerated in anticipation of the proposed “mansion tax” aimed at residential properties valued at £2 million and above, which is slated to take effect in 2028.
Additionally, potential structural overhauls to local taxation continue to cast uncertainty over the market. Commentators have highlighted that the capital’s property market could face further turbulence if political figures press ahead with sweeping alternative levies designed to replace traditional council tax and stamp duty. Such structural tax reforms, pegged directly to contemporary property valuations, risk saddling London homeowners with billions of pounds in supplementary property tax liabilities.
