A recent poll of 500 directors by Directorbank and the venture philanthropy charity the Impetus Trust found that the majority felt their expertise was not being used properly.
Directors said this was because of hand-to-mouth funding, a lack of project management capacity and pressure from the public that donations should be spent on the charity's cause rather than on administration.
"There is strong sense of frustration among business leaders," said Elizabeth Jackson, chief executive of Directorbank. "They want to help charities, but few feel they are making a real difference. It's a wasted opportunity for charities."
Directorbank has formed a partnership with the Impetus Trust to find directors that can assist charities the trust supports.
