Residential property prices in London fell 2.1% year-on-year in March 2026 [1].
The decline reflects a shift in the luxury real estate market as the UK government implements stricter tax rules for foreign investors purchasing high-value homes. This trend suggests that international buyers are becoming less inclined to invest in prime London real estate under the new fiscal regime.
The downturn was most pronounced in the city's most expensive districts. In the City of London financial district, prices fell approximately 20% [1]. Similarly, the Westminster area, home to Big Ben, saw a price decrease of about 11% [1].
Analysts said these specific losses are linked to the increased tax burden placed on non-domestic buyers. By targeting high-value residential properties, the government has altered the cost-benefit analysis for global investors who previously viewed the capital as a safe haven for wealth storage.
Broadly, the downward pressure on prices extends beyond the luxury sector. Data from the Royal Institution of Chartered Surveyors (RICS) showed a housing price index of -34 points for the UK in April 2026 [2], [3]. This indicates a wider trend of price correction across the national market following the March data.
The combination of targeted tax increases and broader economic indicators has created a volatile environment for homeowners and developers. While the 2.1% overall drop in London is modest, the double-digit losses in the financial and political centers highlight a significant retreat of foreign capital from the city's core.

The sharp decline in the City of London and Westminster suggests that the luxury property market is uniquely sensitive to fiscal policy changes. While the overall city-wide drop is relatively small, the heavy losses in prime districts indicate that high-net-worth foreign investment—a long-term driver of London's real estate inflation—is cooling in response to government tax interventions.
