Westminster has recorded the largest annual fall in London house prices, with the average property value dropping to £836,331 in May 2026 — a decline of roughly 23% or about £247,000 compared with the same month in 2025.
What the numbers show
The latest data make Westminster the hardest‑hit central borough in the capital’s market downturn. Analysts point to a mix of factors driving the adjustment: sustained higher interest rates that have increased mortgage bills, recent tax changes and broader political considerations affecting buyer demand.
“It’s a very substantial correction after a very long run of higher house prices,” said Russ Mould, investment director at AJ Bell.
Zoopla’s research director cited softer enquiries and reduced transactions this summer as evidence that activity has slowed; the firm has reported lower buyer interest and fewer sales being agreed compared with a year earlier.
Local consequences
The scale of the fall will affect a range of people in Westminster:
- Homeowners who purchased recently may see significant negative equity or reduced equity.
- Prospective buyers face higher borrowing costs even as asking prices decline.
- Landlords and investors may reassess portfolios in light of weaker rental and capital returns.
- Local councils and services could feel secondary effects through changes in wealth and transaction volumes.
Commentators have also flagged political proposals as a potential further drag on demand should they be pressed ahead. One suggested policy under discussion nationally would replace existing property taxes with a new homes levy, an idea that could alter incentives for both domestic and international purchasers.
Where Westminster sits in the London picture
While Westminster’s fall was the steepest, other central and inner boroughs also saw double‑digit declines or notable corrections. The broader London market recorded an accelerated annual decline to around 3.7% in the year to May 2026, compared with a smaller drop the month before.
| Borough | Average price (May 2026) | Year change |
|---|---|---|
| Westminster | £836,331 | -23% |
| Kensington & Chelsea | £1,256,000 | -10.7% |
| Hammersmith & Fulham | £729,000 | -10.9% |
Industry commentators attribute the market slowdown to a combination of economic, seasonal and political influences. As Richard Donnell of Zoopla observed, factors such as international events and warm weather can depress active buyer engagement alongside structural issues like mortgage pricing.
“Political change, the World Cup, a scorching summer and elevated mortgage rates have hit housing market activity this summer,” said Richard Donnell.
What to watch next
For Westminster residents and market watchers, the next key indicators will be movements in mortgage rates, any confirmed tax or levy proposals from central government, and changes in buyer enquiry volumes through the autumn. Local homeowners considering selling should weigh current valuations and the additional cost of borrowing, while buyers should be aware that lower asking prices can be offset by higher monthly repayments.
The sharp correction in Westminster marks a notable turning point after years of sustained price rises in central London. How quickly values stabilise will depend on the interaction of financial markets, government policy and buyer sentiment in the coming months.
