The organisation said the questions in the survey, which is being carried out by consultancy Strategy Complete, are directed at a charity audience and are not relevant to businesses.
"I am a bit concerned," said Caroline Peat, chair of the APGO, who is also national community investment manager at Business in the Community.
"The few businesses that see the survey will think 'it's not directed at us'.
"I think because it is being led by the IoF, which is a charity-led organisation, we are going to miss the opportunity to have the views of the business sector."
Megan Pacey, director of policy and campaigns at the Institute of Fundraising, said the survey was only one small part of a much larger review.
"Rest assured, we have spoken in the context of the review to professional fundraising organisations, payroll giving agencies, charities and the business community, including both employees and employers," she said.
"The review also includes a series of one-to-one interviews, focus groups and data analysis." The survey findings will be published before April.
Peat is leaving Business in the Community on 7 February, but APGO trustees voted unanimously that she should continue as chair of the organisation.
