Guy's and St Thomas' Foundation

Guy's and St Thomas' Foundation is an independent charitable foundation with over 500 years of roots tied to London's historic Guy's and St Thomas' hospitals, now backed by a £700 million endowment making it one of the UK's largest health-focused funders. Its mission is to advance health equity and wellbeing, enabling everyone to stay healthier longer by tackling root causes of inequality, especially in Lambeth and Southwark, while scaling insights nationally. Guided by equity, optimism, collaboration, and evidence, it blends direct grants to its NHS Trust partner with strategic investments in systems change, research, policy influence, and impact investing.

The foundation prioritizes urban health determinants like poverty's health impacts, childhood obesity, multiple long-term conditions, air pollution, and place-based factors through its Impact on Urban Health flagship programmes. It funds frontline healthcare, preventative interventions, community co-design, population-level research, capital projects (e.g., equipment, neonatal care), and economic initiatives addressing food insecurity or air quality, favoring structural, scalable solutions over short-term projects.

Eligible applicants are UK-registered charities, academic institutions, NHS Trusts, or partnerships with strong local capacity for systemic impact, primarily operating in Lambeth/Southwark (with selective wider London or national reach); it prefers medium-to-large organizations without strict income limits. Unsolicited applications are not accepted—funding is invitation-only or via targeted online form calls with specified deadlines (e.g., patient experience initiatives). Typical grants range £10,000–£1,000,000 (often £25,000–£100,000 locally, larger for multi-year collaborations), awarded ad hoc through strategic partnerships. Distinctively place-based and collaborative, it avoids emergency relief or isolated projects, emphasizing transparency, co-design, and national learning from South London tests.
