Initiative overview
Established in November 2014 and headquartered in Sheffield, the British Business Bank (BBB) is the UK's largest investor in venture and venture growth capital funds. It delivers its mandate through a suite of programmes: equity programmes (Enterprise Capital Funds, British Patient Capital, Long-term Investment for Technology and Science/LIFTS) and debt programmes (Growth Guarantee Scheme, ENABLE portfolio guarantees, Start Up Loans). BBB does not lend directly to most businesses; instead it provides funds and guarantees to accredited fund managers and lenders, crowding in private capital. As of June 2025, the BBB's total financial capacity was increased to GBP 25.6bn, enabling annual investments of approximately GBP 2.5bn and expected to crowd in tens of billions in private capital. In 2024/25, BBB supported GBP 6.8bn of finance for smaller businesses. A new GBP 4bn British Business Bank Industrial Strategy Growth Capital initiative will be deployed across eight growth-driving sectors including digital and technologies, advanced manufacturing, and life sciences, with AI identified as a key vertical. BBB explicitly supports direct early-stage investment into UK AI companies to help keep them in the UK longer term. The LIFTS initiative channelled a GBP 250m BBB commitment alongside GBP 250m from Phoenix Group into a Schroders Capital LTAF for UK science and technology scale-ups including AI companies. In March 2026, BBB committed GBP 50m as cornerstone investor in SuperSeed Fund III, focused on physical AI applications in manufacturing, energy, and construction. Target audience: UK SMEs and scale-ups, with a focus on underrepresented founders and regions outside London.
