The Joseph Rowntree Charitable Trust is to increase its grant spending by more than £3m a year.
This will take the Trust’s annual grant spend up to around £10m, for the next ten years.
The number of grants given to projects outside of London will also be increased, to give the trust a greater geographic spread across the UK.
In addition, the trust is looking to make a number of large, long-term grants to charities where suitable.
The increase was decided by trustees as part of a ten-year review and in response to a steady rise in grant applications.
“We’re pleased to be able to increase our grant funding, which reaffirms our commitment to engage in philanthropy which supports people who address the root causes of conflict and injustice,” said JRCT Secretary Nick Perks.
“JRCT supports organisations and individuals who are working creatively and courageously to produce positive social change through their charitable work.
“We have decided to make more grants across the UK in recognition of the importance of devolved nations and regions and that systemic change requires many voices and experiences.
“We want to be an open and responsive funder and we know that more core or unrestricted grants are what many charities want and could greatly benefit from.”
The trust supports charitable work across five areas: peace and security, rights and justice, power and accountability, sustainable future and Northern Ireland.
Further details of the grants will be released later this year and the changes are set to be fully in place by the end of next year.
