Isio advises the British Business Bank on new British Growth Partnership fund

20 November 2025 : Isio, one of the fastest growing UK pensions, investments, employee benefits and wealth advisory businesses, has advised the British Business Bank on the development of its first British Growth Partnership fund. The British Business Bank is establishing the British Growth Partnership to encourage more UK pension fund and other institutional investment into the UK’s fastest growing, most innovative companies. 

The fund is currently seeking to raise hundreds of millions of pounds to invest in some of the highest potential opportunities in the Bank’s venture capital pipeline. It follows the Government’s Mansion House reforms to encourage more Defined Contribution (DC) and Local Government Pension Scheme (LGPS) investment in productive finance assets, including promising, high-growth UK companies which are the bedrock of economic growth.

Isio has supported the British Business Bank in the development of the fund, helping the Bank leverage its strengths and resources to develop a proposition that aligns its expertise and deal pipeline with institutional investors’ needs.

Leading DC pension fund investors, subject to final terms and relevant approvals, and an LGPS pool have already agreed to work with the Bank on the launch of the British Growth Partnership.

Helyne Slade, Director and Head of DC Investment at Isio, said: “This fund is an excellent proposition for institutional investors seeking new and diverse sources of attractive return. Fully aligned to the Government’s productive finance agenda, it enables investors to benefit from some of the most groundbreaking, high-growth business in the UK and, in doing so, support the domestic economy. The British Business Bank has extensive access and expertise, making this an exciting opportunity for a broad range of investors.”

Ajith Nair, Head of Research at Isio, said: “We are very glad to have been part of this project where we have utilised our venture capital knowledge, and our expertise working with investment managers in building new, high-quality propositions for institutional investors, to help the Bank deliver a product which is a true reflection of their expertise and market reach.”

Ian Connatty, Managing Partner at the British Growth Partnership, said: “The British Growth Partnership is expected to connect some of the highest potential opportunities in the Bank’s venture capital pipeline with the UK’s leading institutional investors, leveraging the Bank’s capability and market access to a range of promising high growth UK companies.

Our work with Isio to develop this fund and refine the offer has helped us to create and refine an investment proposition designed to give pension funds efficient access to the UK’s growth economy.”
