The Charity Commission is not regulating charities effectively and there is a gap between what the public expects of the Commission and what it actually does. The NAO has concluded that the Commission does not do enough to identify and tackle abuse of charitable status. Between 2007-08 and 2013-14, the Commission's annual budget fell 40 per cent in real terms to £22.7 million but the number of main registered charities has remained fairly constant at around 160,000. In response to budget cuts, the Commission has reviewed how it works and successfully reduced demand for its services, but it has not identified what budget it would need to regulate effectively. The Commission makes little use of its enforcement powers, for example suspending only two trustees and removing none in 2012-13. And it can be slow to act when investigating regulatory concerns. The NAO found cases where periods of several months passed during which the Commission took no action. Furthermore, the Charity Commission does not take tough enough action in some of the most serious regulatory cases. It is also reactive rather than proactive, making insufficient use of the information it holds to identify risk. The Charity Commission needs to think radically about alternative ways of meeting its objectives with constrained resources. It also needs to make greater use of its statutory powers in line with its objective of maintaining confidence in the sector; and develop an approach to identify and deal with those few trustees who deliberately abuse charitable status.
