Guy's & St Thomas' Foundation grants: what they fund and how to apply
Guy's & St Thomas' Foundation is an independent health foundation with an endowment worth nearly £1 billion. It does not run open grant rounds. Most of its funding for outside organisations goes through Impact on Urban Health, which partners on health inequalities in Lambeth and Southwark.
What the Foundation funds
The Foundation works to improve health, with a focus on health inequalities. It does this in three main ways: investing its endowment for both financial return and health impact; running Impact on Urban Health, which tackles health inequalities in cities; and backing NHS staff and care across Guy’s, St Thomas’ and Evelina London hospitals.
For most charities, the relevant part is Impact on Urban Health. It focuses on four issues that are more common in urban areas: children’s health and food, children’s mental health, the health effects of air pollution, and financial foundations for adult health. It funds and partners with others to test and grow ideas on these themes.
How much you can apply for
There are no fixed grant bands. The Foundation funds through partnerships and tenders rather than standard awards, so the amount depends on the programme and the work involved. It does not publish a minimum or maximum figure. If you see an amount quoted elsewhere, confirm it directly before you rely on it.
Who can apply
This is not a general UK grants programme. The work centres on the London boroughs of Lambeth and Southwark. Impact on Urban Health says you do not have to be based there to talk to them, and it works with local, national and international partners. But its goal is better health in those two boroughs, so a broad grant for a charity elsewhere in the UK is unlikely to fit.
Deadlines and rounds
There are no rolling grant deadlines. Impact on Urban Health describes getting in touch as starting a conversation, not an application process. From time to time it runs tenders for specific pieces of work, each with its own timetable. Check the tenders page for anything currently open.
How to apply
For programme work, use Impact on Urban Health’s “Become a partner” page to share your idea, or respond to a live tender. For investment, property, or arts and heritage, use the Foundation’s “Partner with us” page. Read the relevant programme pages first, then set out clearly how your idea helps improve health in Lambeth and Southwark.
Tips
- Match your idea to one of the four Impact on Urban Health programmes before you make contact. A clear fit is the main thing they look for.
- Be specific about the link to Lambeth and Southwark, even if your organisation is based elsewhere.
- Watch the tenders page if you want a defined, funded piece of work rather than an open-ended partnership.
- Do not expect a standard grant form or a set award size — this funder works differently from most trusts.

Frequently asked questions
Not through an open application form. The Foundation is endowment-based and works by investing, partnering and influencing. Its grant-style funding for outside organisations runs mainly through Impact on Urban Health, which asks people to share an idea and start a conversation, and runs tenders on set programmes. There is no rolling grants scheme.
Better health and, in particular, health inequalities. Through Impact on Urban Health it focuses on four issues that hit urban areas hardest: children's health and food, children's mental health, the health effects of air pollution, and financial foundations for adult health. The Foundation also invests its endowment for both financial return and health impact.
The work centres on Lambeth and Southwark. Impact on Urban Health says you do not have to be based in Lambeth or Southwark to talk to them, and it works with local, national and international partners. But the aim is to improve health in those boroughs, so a general grant for a charity elsewhere in the UK is unlikely. Check the fit before you get in touch.
The Foundation does not publish fixed grant bands, because it funds through partnerships and tenders rather than standard awards. Amounts depend on the programme and the piece of work. Treat any figure you see elsewhere with caution and confirm directly. Checked again 11 July 2026: still no published grant sizes anywhere on the Foundation's or Impact on Urban Health's sites.
For programme work, use Impact on Urban Health's "Become a partner" page to share your idea, or reply to a live tender. For investment, property or arts and heritage, use the Foundation's "Partner with us" page. Both sites list a contact route. Read the programme pages first so your idea matches their current focus.
