Dame Stephanie Shirley, the Government's philanthropy ambassador, will chair a new panel of philanthropy advisers that will try to persuade wealthy people to give to charity.
The group will include bankers, lawyers and representatives from community foundations. Members will share knowledge with each other so they are better placed to advise philanthropists on how to give away their money.
The formation of the new group is announced in a report by think tank New Philanthropy Capital, called The Business of Philanthropy, which will be published this week. In the report, Shirley says there is too little philanthropy advice in the UK.
"Together we will ensure that philanthropy advice is promoted as widely as possible, with the highest standards of best practice, so that wealthy individuals will give more and think differently about the way in which they give for maximum reward and impact," she says.
The report says the recession has made some wealthy donors reluctant to discuss giving money away.
Bankers and lawyers are sometimes disinclined to discuss philanthropy with their wealthy clients, the report says.
