The survey, which follows a similar exercise two years ago, will feed into the commission's attempts to fulfil its new statutory objective of increasing public trust and confidence in charities. The tender for a specialist in quantitative surveys is going out today.
Rosie Chapman, director of policy and effectiveness at the regulator, said the new study would allow the commission to see how things have changed since 2005.
"It will be interesting to see whether things have shifted," she said. "We're also hoping to look at perceptions in more detail and see how age, gender and ethnic background affect people's views of charities."
The 2005 survey revealed that trust in the sector was grounded in assumptions rather than rational observations. Asked to rate their trust of charities on a scale of one to 10, respondents awarded an average of 6.3.
Chapman said the survey should take place in January and that results should be ready by April.
