House prices in Kensington and Chelsea, London’s most affluent borough, have plunged to their lowest level since 2013, reflecting ongoing challenges in the prime London property market. In March, the average price in this prestigious area fell by 15.1% year-on-year, settling at £1.19 million. This decline is attributed to a confluence of factors, including increased property taxes, uncertainty surrounding Brexit, and significant changes to the non-domicile tax rules.

While Kensington and Chelsea have seen prices drop, the overall trend in the UK housing sector presents a stark contrast. In March 2025, house prices across the UK rose by an annual rate of 6.4%, reaching a record high of £271,000. This surge, the fastest since December 2022, has been driven by a rush among buyers to complete transactions before the expiration of temporary tax incentives and looming tax increases for properties valued above £300,000. The interplay of these factors illustrates a dual narrative within the property market: the broad-based recovery outside of prime London versus the continued struggle of its high-end segments.

The situation in Kensington and Chelsea is not isolated; it reflects a broader trend of declining prices in several premier locations in the capital. Areas like Hammersmith and Fulham, along with Westminster, also reported significant declines, with annual reductions recorded at 13.2% and 20.1%, respectively. This persistent downturn has endured for at least 15 months in these neighbourhoods, highlighting a troubling pattern for luxury properties.

Lucian Cook, head of residential research at Savills, noted that the “prolonged bull run” enjoyed by the prime London market shifted significantly around 2014. Major reforms to stamp duty created a wider gap in fees between luxury properties and their more affordable counterparts, placing added pressure on high-end buyers. The cumulative impact of factors such as Brexit, the end of the non-domicile tax regime, and rising interest rates has made the market increasingly dependent on international investments, rather than local mortgage accessibility.

In a major policy shift, the non-dom tax regime was abolished last year, following significant political discourse. This long-standing rule allowed foreign nationals to earn money from overseas without incurring UK tax for a period of up to 15 years. The removal of this incentive has been seen as a setback for attracting wealthy buyers, particularly at a time when competition from other global luxury markets is tightening.

Additionally, recent changes in stamp duty have introduced further complications. The expiry of a temporary stamp duty relief in April has reverted thresholds back to pre-2022 levels, placing a financial burden on first-time buyers. Despite this, the impact of these tax reforms has been minimal on the overall national market, which has continued to rise, particularly in regions such as the North East, boasting an impressive annual increase of 14.3% in March.

Stuart Bailey, head of super-prime London sales at Knight Frank, pointed out that London’s luxury market has experienced a “10-year slow ebbing in pricing,” attributable to declining demand driven by rising taxes and political uncertainties. He observed that the rapid price increases that characterised the period leading up to 2014 were unsustainable, resulting in a long-term decline.

Looking ahead, analysts suggest that any recovery in the prime London market will hinge on improved economic conditions and a renewed influx of investment into the capital. Richard Donnell, executive director of property consultancy Houseful, noted that sustained growth in high-end areas is “dependent upon stronger economic growth” and suggests the need for a revitalisation of buyer sentiment.

As the market navigates these challenging dynamics, the contrasting trends in luxury and mainstream segments become increasingly evident. While many buyers continue to face uphill battles in securing high-value properties within prime London, a parallel story of recovery is unfolding across the UK, painting a complex portrait of the current real estate landscape.
