British billionaire David Reuben has left the UK for Monaco, putting renewed attention on the increasing number of wealthy Britons relocating overseas.
The 88-year-old property tycoon, who once topped The Sunday Times Rich List, reportedly moved from west London to Monaco this summer.
Here are several things to know about David Reuben’s move and his billionaire fortune.
1. David Reuben has moved to Monaco
A report suggested Reuben has relocated from his home in Holland Park, London, to Monaco. His younger brother, Simon Reuben, has already been residing in the principality for around four decades.
A spokesperson confirmed David Reuben’s move; however, further details remain under wraps.
2. The Reuben brothers are worth nearly £28 billion
David and Simon Reuben ranked second on the 2026 Sunday Times Rich List, with their combined net worth projected at nearly £28 billion.
Their fortune has been built via investments spanning property, commodities, private equity and data centres.
3. Monaco has become a billionaire hotspot
The significant underscores Monaco’s appeal to wealthy Britons. The principality generally has no personal income tax, capital gains tax and inheritance tax.
Nearly £77 billion of wealth on this year’s Rich List is controlled by UK citizens living in Monaco.
4. UK tax reforms are under the spotlight
Reuben’s relocation comes amid significant changes to Britain’s tax rules for wealthy residents.
The UK abolished its long-standing non-dom regime in April 2025, while changes involving inheritance and capital gains taxation have ignited concerns among some wealthy persons.
5. His UK business empire remains intact
Despite leaving Britain, Reuben is not abandoning his UK interests. The family persists to own significant London property assets, while the brothers also hold a stake in Newcastle United.
Additionally, David Reuben is also involved in significant restoration projects involving historic London buildings.
The move adds a new chapter to the debate over whether Britain’s changing tax environment is encouraging billionaires to look elsewhere.
