The number of organisations applying for charitable status was 27 per cent higher in October 2010 than in October 2009, according to the Charity Commission.
Figures released by the commission before its open board meeting in Liverpool today showed that the regulator received 571 applications in October 2009, compared with 728 in the same month this year.
In his report, to be presented at the meeting, Sam Younger, the regulator's chief executive, said there was "no obvious reasons for this increase".
The report also revealed that the commission plans to set up a new panel of independent complaints reviewers. Its existing independent complaints reviewer, Jodi Berg, will step down next month after 10 years in the role.
Under the new system, the report said, one person from the panel would be called upon each time a new case needed to be investigated.
The board papers said the commission was "running a competition" to select members of the panel and there had been strong interest in this. The panel will be appointed in December.
They also showed that the High Court case to hear the Independent Schools Council's objections to the commission's interpretation of public benefit law was expected to be heard in May next year.
