Sector organisations have stepped in to support the ImpACT Coalition after the Institute of Fundraising decided to reduce its £50,000 annual grant.
The institute said it would be cutting the amount it gives to the coalition, which works to improve charities' transparency and accountability, but said the figure was under review and could not say how much funding it would provide.
The Charities Aid Foundation has given £15,000 to the initiative, and the Charity Finance Directors' Group and the Public Fundraising Regulatory Association have each agreed to provide £5,000. The grants came into effect on 6 April.
A spokesman for CAF said its grant was a one-off donation to make the project sustainable, given what it called "significant reductions in income from the institute's strategic grant".
Lindsay Boswell, chief executive of the Institute of Fundraising, said it was looking for a "more sustainable funding model" for the coalition. He said the initiative was not only about fundraising: "We're keen that ImpACT's funding model reflects its delivery model."
The CFDG said it gave its grant in response to a direct request for financial support. Keith Hickey, chief executive of the umbrella body, said: "It is important we make sure the coalition is sustainable."
Richard Marsh, director of the coalition, said he welcomed the more diversified funding arrangements.
