Britain's Richest Individuals: A March 2026 Snapshot

How individual fortunes were built, from chemicals and discount shops to games and investment firms. This takes the 30 largest entries recorded with United Kingdom citizenship in Forbes's 2026 annual billionaire list, using its 1 March valuations. Citizenship defines eligibility, including people living abroad; it is not a ranking of UK residents. Values are estimated net worth in US dollars, with bn meaning billion. Entries labelled 'and family' are excluded. Relatives with separately attributed estimates remain separate, and equal amounts are ties, shown in the source's order. These are ownership estimates, not cash balances or company revenues. The list preserves that published snapshot rather than updating prices.
