The ICM poll of 1,160 adults also found that almost half of donors give directly to charity at Christmas, donating an average of about £46 to good causes.
The survey revealed that 81 per cent of those who donate at Christmas will give around the same amount this year as they did in 2011. Eight per cent of respondents will give more and nine per cent said they would give less.
The commission and FRSB have launched a Safer Giving Christmas campaign to highlight the risk of fraud to donors and charities, issuing tips advising people how they can give with confidence. These include asking a collector for their ID or checking the commission’s online register.
Only 11 per cent of people surveyed check for the FRSB ‘give with confidence’ branding, which indicates that a charity’s fundraising is regulated.
Alistair McLean, chief executive of the FRSB, said increasing numbers of public complaints to the organisation questioned the legitimacy of fundraising appeals. "Where charity fraud occurs, it not only diverts much-needed funds from the nation’s charities, but it comes at an even greater cost of damaging public trust and future giving," he said.
Sam Younger, chief executive of the Charity Commission, said: ‘While it is encouraging to see many people do take steps to check whether a charity is registered before giving, this poll shows there is still much to be done to raise awareness of charity fraud to donors and charities."
