London After Non-Dom: Where the Wealth Is Actually Going

The end of a 200-year tax regime

The abolition of the UK's remittance basis in April 2025, and the introduction of a residence-based regime with a four-year exemption window, marked the end of a tax structure that had defined London as a global wealth hub for two centuries. The political rhetoric framed it as a closing of a loophole. The practical consequence has been the largest measurable outflow of high-net-worth residents from the United Kingdom in modern record.

Estimates from Henley & Partners and New World Wealth put net HNW departures from the UK in 2024 alone at over ten thousand individuals, with a meaningful share holding net worth above ten million pounds. The 2025 and 2026 figures are projected to be larger as the four-year window for transitional planning closes for those who arrived recently.

Where they are going

Three jurisdictions dominate the destination data: the United Arab Emirates, Italy, and Switzerland. Each offers a structural answer to a different version of the problem.

The UAE — primarily Dubai and Abu Dhabi — captures the largest share. Zero personal income tax, no inheritance tax, no capital gains tax, a Golden Visa structure that grants ten-year residency on relatively modest investment thresholds, and a quality-of-life proposition that has matured significantly over the past five years. The UAE is the dominant choice for younger entrepreneurs and families with tech, crypto or international business income.

Italy has emerged as a surprise winner. The flat-tax regime introduced in 2017 — one hundred thousand euros per year on all foreign-source income, regardless of amount, for up to fifteen years — is structured almost identically to the UK non-dom regime it has effectively replaced. Milan and Rome have become the primary destinations for wealth that wants to remain in Europe with cultural and lifestyle continuity to the UK.

Switzerland's lump-sum taxation regime, available in most cantons, allows negotiation of a fixed annual tax based on living expenses rather than income. Geneva and Zug remain the primary destinations, particularly for older HNWs prioritising banking continuity, language, and proximity to UK family.

The pattern within the pattern

What is interesting in the data is the family structure of who is leaving. It is not single individuals. It is families — typically with school-age children, multiple property interests, and existing UK business or investment exposure that has to be unwound over months or years. The relocations are major projects, not casual moves.

This is the category Atrium increasingly serves. A household relocating from London to Dubai or Milan is not making a single decision. They are coordinating tax counsel in three jurisdictions, residency applications, school placements, property acquisitions, business restructuring, and the ongoing management of UK assets that often cannot be liquidated quickly. The coordination burden is the actual challenge — the destination choice is the easy part.

What stays in London

Important nuance: most departing families retain UK property, UK business interests, and UK family ties. They are not severing the relationship with London. They are restructuring it. The new normal is multi-jurisdictional living — tax resident in the UAE, business interests in the UK, education in Switzerland, holiday property in Italy. The four-resident family is no longer unusual at this tier; it is becoming the default.

This is why the family office model — coordinating across jurisdictions through a single relationship — has become structurally necessary rather than aspirational for households at this level. The complexity is no longer optional.
