The UK's overhaul of the non-domiciled tax regime represents the most significant structural change to the London prime property market in decades. The reforms, which came into full effect in April 2025, fundamentally altered the tax treatment of foreign income and gains for non-UK residents, reducing the grace period from 15 years to just 4 years.
The quantifiable impact on wealth migration has been substantial. In 2024, the number of UK millionaires departing exceeded 10,000, representing a 157% increase from the previous year. Projections for 2025 indicated that 16,500 millionaires would relocate from the UK, marking the largest documented wealth exodus in modern British history. The United Arab Emirates emerged as the primary destination, recording a net inflow of approximately 9,800 millionaires in 2025 — the highest net migration to any single country globally.
This capital reallocation has had direct consequences for London's residential property market. Analysis of transaction data from 2025 reveals that approximately 70% of vendors listing properties priced at £15 million and above were non-domiciled sellers. The resulting supply-side pressure has manifested in measurable price softening across multiple segments. Properties in the £2 million to £5 million bracket experienced declines of 10% to 15%. The broader £5 million-plus market saw transaction volumes decline 11% year-over-year in 2025, with total transaction value falling to £4.09 billion.

On 28 February 2026, coordinated military strikes by the United States and Israel against Iran triggered the most significant regional disruption to Middle Eastern markets in recent years. The Iranian response included over 1,130 missiles and drones launched across the Gulf, with debris reported in urban areas of the UAE for the first time in modern memory.
The immediate market response was severe. The Dubai Financial Market Real Estate Index, which tracks publicly listed real estate developers including Emaar Properties and other major developers, experienced a sharp decline. Within two weeks of the conflict's onset, the index fell approximately 21% from its pre-conflict levels. Some analyses documented the decline reaching as much as 30% from the peak of 16,910.3 recorded on 27 February 2026.

Despite the equity market shock, the UAE's air defence systems successfully intercepted more than 95% of incoming threats, and no major real estate assets sustained structural damage. However, the psychological impact on buyer confidence and transaction activity was pronounced. Site visits were cancelled, off-plan signings paused, and brokers across Marina, Downtown, and Palm Jumeirah reported buyers requesting more clarity before proceeding.
Transaction data from the immediate aftermath of the conflict reveals a sharp but uneven market contraction. Total property sales registered between late February and 22 March came in at approximately 8,059 units, well below the level normally observed in that early-year window.
Pricing adjustments were modest but measurable. Average property prices softened by approximately 4% to 5% during this period. Critically, however, the market did not collapse uniformly. The market became highly selective, with truly prime stock — scarce villas in Emirates Hills, branded residences on Palm Jumeirah, and signature penthouses in Downtown Dubai — continuing to attract serious capital deployment.

The weekly transaction data demonstrates a sharp trough in early March, with volumes recovering steadily through April. By late April, weekly transaction volumes had returned to near pre-conflict levels, indicating that the market pause was temporary rather than structural.
