Britain’s Wealth Exodus Drives Demand for Cross-Border Planning

16,500 millionaires left the UK in 2025, marking a record outflow, as Headway Wealth underscores the importance of independent advice for internationally mobile individuals.

Durham, UK - May 22, 2026 - As the UK records a historic outflow of high-net-worth individuals, Headway Wealth is pointing to the growing need for independent, FCA-regulated cross-border financial planning for internationally mobile clients. Driven by the abolition of non-dom tax status, which was formally enacted in April 2025, alongside sweeping inheritance tax reforms and a tax burden at its highest level since the 1940s, the departure of high-net-worth individuals accelerated sharply through last year. According to Henley & Partners’ Private Wealth Migration Report, the UK recorded the largest net outflow of millionaires of any country in history in 2025, more than double the number that left China in the same period.
