Decline in London House Prices Amid Budget Speculation

Significant Price Drops in Wealthy Boroughs
In November 2025, house prices in London experienced their most significant decline since the global financial crisis, with an average drop of 4.6% year-on-year. This followed a 4.3% decrease in October, marking a troubling trend for the capital's property market. The most pronounced falls were observed in affluent boroughs, particularly Kensington and Chelsea, where prices plummeted 16.3% to an average of £1.19 million, and Westminster, which saw a 15.5% drop to £866,000. In contrast, outer London boroughs like Havering and Bromley reported annual price increases of 5.2% and 6%, respectively, contributing to an overall 1.2% decline in average house prices across London, which now stands at approximately £553,000.
Factors Behind the Decline
The downturn in London's housing market has been attributed to speculation surrounding potential tax changes in the lead-up to Chancellor Rachel Reeves' Autumn Budget. Many prospective buyers adopted a "wait and see" approach due to uncertainty regarding property taxes, including a newly introduced high-value council tax surcharge for properties valued over £2 million, set to take effect in April 2028. This surcharge, often referred to as a "mansion tax," will range from £2,500 to £7,500 depending on the property's value. Other tax rumors, such as changes to stamp duty and the introduction of capital gains tax on primary residences, contributed to market apprehension but were ultimately excluded from the Budget.
Broader Market Trends
While London faced a downturn, the average UK house price rose by 2.5% to £271,000 in November, marking the first acceleration since June. The North East recorded the highest increase at 6.8%. Analysts suggest that falling mortgage rates could further bolster the market in 2026, contingent on renewed buyer confidence. Paige Tao, an economist at PwC UK, indicated that the less disruptive nature of the Budget and anticipated interest rate cuts by the Bank of England could help restore market activity in the New Year.
Criticism and Market Sentiment
Critics have pointed to a combination of increased supply, low buyer demand, and rising living costs as factors exacerbating the decline in London. Nathan Emerson, chief executive of Propertymark, highlighted the chronic undersupply of rental properties, which has led to continued high rental prices in London, averaging £2,268 per month. Tom Bill, head of UK residential research at Knight Frank, emphasized that confidence remains a crucial missing element for buyers amid ongoing economic and political volatility.
