Britain's New Billionaires: The 2026 UK Rich List Reveals 17 New Entrants
From property technology to pharmaceutical breakthroughs, 17 British entrepreneurs crossed the billion-pound threshold this year
Britain has welcomed 17 new billionaires in 2026, according to the annual Sunday Times Rich List, bringing the total number of UK billionaires to a record 186. The new entrants made their fortunes across a diverse range of sectors, with artificial intelligence, property technology, healthcare diagnostics, and sustainable energy producing the largest number of new names.
The Newest Members of the Club
The largest new fortune belongs to Dr. Catherine Aldridge, whose AI-powered drug discovery company, Helix Genomics, was acquired by a US pharmaceutical major for £3.4 billion. Aldridge, who founded the company with two Cambridge colleagues in 2018, retains a 34% stake that values her personal holding at approximately £1.16 billion.
Second on the new entrants list is Marcus Webb, who built HouseSimple, a property technology platform, from a seed-funded startup to a business processing over £12 billion in annual transaction value. His stake was valued at £1.08 billion following a secondary share sale earlier this year.
The Sectors Leading the Way
Artificial intelligence and machine learning contributed four new billionaires — more than any other sector. Healthcare technology produced three. Sustainable energy and climate technology accounted for two. Property technology, fintech, and e-commerce each produced one or two new billionaires.
The dominance of technology sectors in this year's new entrant list reflects a broader pattern: the most significant wealth creation in Britain over the past decade has increasingly come from technology rather than from the financial services and property that dominated earlier generations of the Rich List.
