An estimated 16,500 millionaires left the UK in 2025, marking the largest millionaire outflow ever recorded for a single country in migration reports

An estimated 16,500 millionaires left the UK in 2025, making it the largest recorded outflow of wealthy individuals from any single country, according to migration reports. The scale of the departure marks a significant moment for the British economy and places the UK at the top of global rankings for millionaire emigration.
The exodus comes amid ongoing concerns over tax policy, economic uncertainty and long-term growth prospects. Analysts say high net worth individuals are increasingly seeking jurisdictions offering lower taxes, greater political stability and more favourable investment conditions. Popular destinations reportedly include parts of Europe, the Middle East and Asia.
Economists warn that the loss of wealthy residents could have broader implications for public finances, investment and charitable giving. While millionaires make up a small share of the population, they contribute disproportionately to tax revenues and capital inflows. Critics argue that persistent policy uncertainty risks accelerating the trend unless confidence is restored.
The government has previously downplayed the impact of millionaire migration, pointing to overall levels of foreign investment and job creation. However, the record scale of departures in 2025 has renewed debate over how to retain wealth and talent in the UK as global competition for high-net-worth individuals intensifies.
