About Guy’s & St Thomas’ Foundation
We are an independent foundation investing in a healthier society. We focus on backing people and ideas to drive more equitable health. For over 500 years, we have been a constant in London’s ever-changing landscape, at the leading edge of health.
Health is a collective outcome, created by the environments around us, supported by the agency of individuals and communities, and maintained through access to quality healthcare.
Our work as a foundation is active across each of these areas. We pioneer original approaches to health. We learn what works where and why. We then share that widely with those who have the ability to affect change systemically. In doing so, we work with a multiplicity of partners, among them funded partners including our local NHS partners through which we support the incredible staff and patients across Guy’s and St Thomas’ NHS Foundation Trust, policymakers, opinion formers, peers and commercial organisations.

Where we work
Our work takes place in the South London boroughs of Lambeth and Southwark – it is a place that combines enduring inequalities and solutions that have shaped the world. In the heart of the capital, Lambeth and Southward are two densely populated boroughs.
Our boroughs are vibrant and have a rich social and ethnic mix. The proportion of Black residents is amongst the highest in the country, with a long-established Caribbean community. Our boroughs are also home to more recent migrants from Africa, Europe and Latin America.
How we are set up
The Foundation is focused on three core business areas of urban health, investments and charitable fundraising and funding, achieving impact through five external brands, and supported by internal, enabling functions:
