UK Budget 2026: £20.4bn Capital Boost Planned for National Wealth Fund and British Business Bank

Split between the two lenders
Britain will provide £20.4 billion of additional capital to the state's business lender and infrastructure bank in next week's Budget, the Financial Times reported on Friday, citing the Treasury. Reuters reported the same figures on 24 October 2026. The Treasury will allocate £15.4 billion more to the National Wealth Fund and £5 billion more to the British Business Bank over roughly half a decade.
A Treasury spokesperson told the Financial Times: "This additional capital will help more British businesses fulfil their potential, while getting investment behind the industries, infrastructure and places that create good jobs and drive lasting growth across the country." The Treasury did not immediately respond to a Reuters request for comment outside regular business hours.
Jobs and sectors in focus
The Treasury said the funding would help support around 100,000 jobs by 2035 in sectors including artificial intelligence, defence and green energy, according to the report. That jobs figure is a Treasury estimate linked to the investment, not a count of jobs already created.
The measures are expected to be announced in finance minister John Healey's Budget on Wednesday. The Budget documents will be the place to check the timing of the capital, any conditions attached to it, and how the National Wealth Fund and the British Business Bank will deploy the extra money alongside private investment.
