Summary
The British Business Bank has confirmed the first close of British Growth Partnership Fund I at £200 million, with commitments from four cornerstone investors: pension funds Aegon UK, Cushon Master Trust, M&G, and the British Business Bank itself. The close, achieved at the end of the 2025-26 financial year, represents a significant milestone in channeling institutional pension capital into UK venture capital allocations.
The fund's investor composition is notable for two reasons: it marks the first venture capital investments for both Aegon UK and Cushon, signaling a strategic shift among major UK pension schemes toward alternative assets. Both are large defined contribution schemes and Master Trusts, institutions historically underweight in venture allocations. The British Business Bank's partnership with Mobius on a unit-linked structure specifically facilitated the Cushon investment, demonstrating structural innovation to accommodate institutional pension fund requirements.
This fundraise is significant as the British Business Bank's first capital raise involving external institutional investors beyond government funding. The participation of three major pension schemes underscores growing momentum around venture capital allocations from Mansion House Accord signatories—a UK financial services initiative promoting long-term investment in growth companies.
The fund has already begun deploying capital, with an £8 million investment in Wayve, a UK autonomous driving company, representing the first commitment from the vehicle. Fund investors now have direct access to the British Business Bank's curated pipeline of over 150 venture funds, providing diversified exposure to UK growth-stage companies through a single investment vehicle.
