The Institute of Fundraising is to survey members on whether they want the Telephone Preference Service regulations to be reviewed.
The institute has launched a survey today with fundraising consultancy Relationship Marketing asking members how they would like to carry out telephone fundraising.
The poll, which has been sent to 5,000 institute members, will also ask how they would like to use the telephone to contact donors or potential supporters, what they understand about the TPS regulations and whether the rules need changing.
The telephone preference service allows the public to choose to stop sales calls, including those from charities, to their homes.
Hugh McCaw, chief executive of Relationship Marketing, wrote a paper earlier this year about the service and the damage it could be doing to telephone fundraising by charities.
One solution, he said, might be to review the regulations so people could allow calls from charities but not commercial organisations.
Lindsay Boswell, the institute's chief executive, said: "This survey is going to help us determine whether there is an appetite for change among our members when it comes to telephone fundraising and the TPS regulations.
"We are keen to push for change if fundraisers feel that reform would mean the potential to raise more money, which is especially necessary in the current climate."
Members have until 21 August to respond.
