The Institute for Voluntary Action Research (“IVAR”) is a small research charity who works with other charities, foundations, and public bodies.
They have recently launched a new report with the title ‘The holy grail of funding – Why and how foundations give unrestricted funding’ and you can download it using the link at https://www.ivar.org.uk/publication/the-holy-grail-of-funding/
It showcases 12 trusts and foundations that offer unrestricted funding, and analyses the benefits to both the trusts and the charities they support.
If you apply for unrestricted funding, this should help your case for support be even more persuasive.
