London homeowners have enjoyed a notable boost in property values over the past month, standing out against a nationwide backdrop of declining house prices. According to the latest House Price Index (HPI) data from April 2025, the average property in London increased by 2.6% month-on-month to reach £566,614, while showing a 3.3% gain over the year. This contrasts with the broader UK market, where house prices fell by nearly 3% compared to March, marking the first month-on-month decline this year. The average UK home was valued at £265,497 in April, reflecting a 2.7% decrease from the previous month but a 3.5% increase annually.

The divergence in trends owes much to recent modifications in stamp duty tax, implemented in early April, which raised transaction costs for buyers, especially for pricier homes. The changes effectively reversed the temporary stamp duty holiday seen earlier when thresholds were higher, resulting in a surge of purchases in March followed by a cooling in April. This fiscal adjustment has particularly impacted properties above certain price points, dampening buyer enthusiasm in much of the UK outside London.

London’s affluent boroughs, including Kensington and Chelsea, the City of London, and Westminster, reported impressive monthly price rebounds. Kensington and Chelsea stood out with a 9% increase, adding on average £123,815 to property values, pushing typical prices to £1.34 million. Similarly, the City of London saw a 7% rise, while Westminster enjoyed a 3% uptick. However, despite these short-term gains, all three boroughs still recorded lower property values compared to the same month last year, with Westminster experiencing the sharpest annual decline of 15%, losing nearly £145,000 on average.

Across the capital, 16 boroughs registered increases, 10 faced declines, and seven remained stable. Notably, areas like Epping Forest on the London-Essex border and Hackney saw significant monthly falls of 4% and 3%, respectively, reflecting the uneven nature of the market within London itself.

The broader UK market, meanwhile, exhibits signs of a temporary slowdown linked to the introduced stamp duty changes. The 2.8% monthly drop reported for April marks the steepest decline in nearly four years and pushed the average house price down to £265,000. This cooling has been particularly pronounced in the South West, which recorded a 3.8% monthly decline, with annual growth slowing to just under 1%. Economists largely view this as a short-term correction following heightened activity in March, with some data indicating rising prices resumed in May.

The Office for National Statistics confirmed a halving in the annual house price growth rate in April to 3.5% from 7% in March, reflecting the fiscal policy’s influence on market dynamics. Meanwhile, the rental market continues to experience robust demand, with rents rising by 7% annually, albeit with a slight slowdown in growth over recent months due to persistent supply shortages.

Experts in the property sector remain cautiously optimistic. Analysts from Purplebricks emphasise that the monthly dip is a minor setback following April’s tax changes, suggesting that property remains one of the best long-term investments. Increased wage growth and low mortgage rates with options for zero deposits are expected to stimulate first-time buyer activity, which could, in turn, energise the property market across the board over time.

Regional data also highlight differing trends across the UK. For example, house prices in England rose by about 3% annually, averaging £286,000, while Wales and Scotland saw slightly higher increases of around 5%. Transaction volumes have decreased somewhat compared to last year, but remain robust compared to historical figures. Regional hotspots like Elmbridge, Bromley, and Lewisham enjoyed double-digit annual percentage gains, contrasting with areas like Westminster and the City of London, which saw steep yearly declines.

Overall, while April’s data presents a complex picture of cooling in many UK regions, London’s resilient performance and ongoing demand signals suggest the housing market’s underlying strength may endure beyond the short-term fiscal impacts.
