The Institute of Fundraising and umbrella body the NCVO are urging fundraisers to become charity trustees.
The institute is writing to its members to suggest that they take up voluntary roles on the boards of other charities. It will ask them to use the NCVO's trustee recruitment service to find suitable vacancies.
Lindsay Boswell, chief executive of the institute, said its members felt trustees often did not understand fundraising and could have unrealistic expectations of fundraisers.
"Imagine if all 5,000 of our members joined boards of trustees," he said. "It would mean that the same number of trustee boards were populated by professional fundraisers, which can only be good for the sector."
Stuart Etherington, chief executive of the NCVO, said: "With the often complex legal responsibilities of trustees, fundraising can be overlooked or avoided on boards, especially because of nervousness about the complex rules relating to fundraising."
