The United Kingdom has experienced an unprecedented exodus of wealthy individuals, with the number of millionaires leaving the country more than doubling from 4,200 in 2023 to a staggering 10,800 in 2024. This dramatic increase reflects a growing trend of high-net-worth individuals seeking more favourable economic conditions elsewhere. The exodus has been attributed to a combination of factors, including an increasingly burdensome tax system, deteriorating infrastructure, and concerns about mass migration and security.
The current wave of departures follows a period of significant wealth migration between 2017 and 2023, during which 16,500 millionaires left the UK. This earlier exodus was primarily driven by uncertainties surrounding Brexit and the economic fallout from the COVID-19 pandemic. The cumulative effect of these departures has led to a substantial reduction in the UK’s millionaire population, with potential long-term consequences for the country’s economy and tax base.
Analyst Andrew Amoils points to the UK’s tax system as a major factor in driving wealthy individuals away. The country’s high capital gains and estate duty rates are particularly unattractive to business owners and retirees. Additionally, the perceived decline in the quality of public services, notably the National Health Service, has contributed to the decision of many millionaires to seek residence elsewhere.
These departing millionaires are relocating to various global destinations, with cities like Paris, Dubai, Amsterdam, Monaco, Geneva, Sydney, and Singapore emerging as popular choices. These locations offer a combination of favourable tax regimes, robust infrastructure, and high quality of life. For those looking to retire, places such as Florida, the Algarve in Portugal, Malta, and the Italian Riviera have become increasingly attractive.
The exodus of wealth from the UK is not limited to millionaires. The country has also seen a significant decrease in its billionaire population, dropping from 102 in 2019 to just 75 in 2023, representing a 26% decline in a single year. This trend suggests a broader loss of confidence in the UK’s economic foundations and highlights the need for comprehensive reforms to retain and attract high-net-worth individuals.
The implications of this wealth migration extend beyond immediate tax revenue losses. It signals a potential shift in the UK’s status as a global financial hub and raises questions about the country’s long-term economic competitiveness. As the exodus continues, policymakers face the challenge of balancing fiscal needs with creating an environment that encourages wealth creation and retention.
