There are many streams of funding for organisations within our community. As the previous post indicates the best source of information is the yearly accounts, if you what to see who fund whom.
Usually there are a mix of funding streams. Direct from government i.e. Department of Health, Primary Care Trusts & local councils, established trust's and "Joe public's" pocket.


It also help to look at the annual accounts from GMFA, stonewall and other organisations on how funding is received and spent on projects relevant to the HIV & GLBT community.
