For investment service providers

Thank you for your interest in the Endowments Investing Challenge (EIC) 2026.


The EIC brings together a group of values-led charitable foundations to select an investment service provider (ISP) to manage a collective mandate that prioritises positive impact for future generations. This process offers a unique opportunity to compete for a substantial investment mandate, gain visibility at a high-profile event, and help shape the future of responsible investing in the UK.


Shortlisted ISPs (expected to be five) will be invited to present their investment solutions at a live event on Wednesday 25 March 2026 at the Barbican, London, attended by investors, foundations, the Future Generations Panel and sector leaders.


In the previous challenge, an investment mandate of £33.5 million now belongs in a fund that has grown to over £750 million in assets under management — demonstrating the potential scale and visibility this process can offer.
