The Fundraising Standards Board says that 225 new organisations joined the regulatory body last year.
Its annual report, published today, shows that by the end of 2013 total FRSB membership stood at 1,547 organisations. It says that 93 per cent of members renewed their membership for 2014. The regulator said that those that left had done so because of mergers or lack of funds.
Membership by fundraising suppliers, which includes companies that provide fundraising services to charities, also increased, with 94 of this type of organisation signing up in 2013.
The report says a fifth of new charity members have annual incomes of £1m or more, taking total membership in this category to 366.
The majority of members, 991, have incomes of less than £1m and the smallest category of members, 83, have incomes of more than £10m.
The largest organisations – those with incomes of £50m or more – pay membership fees of £5,000 a year, while the smallest, with incomes of up to £10,000, pay £30.
The FRSB said it did not include data on complaints in its annual report for the second year running, and that it would instead publish this information in a standalone document in June.
The accounts show that it made a surplus of almost £6,000 in 2013, down from a surplus of more than £60,000 in 2012.
Meanwhile, its administration expenses increased to about £490,000, from a little over £410,000 the year before.
The report says that in 2014 the organisation will focus on increasing membership by organisations with annual incomes of more than £1m and will attempt to build public awareness that fundraising is regulated.
These goals are a reflection of the government’s priorities as stated in its response to two reviews, conducted by Lord Hodgson and the Public Accounts Committee, of the Charities Act 2006.
"At the start of 2013, we set out to strengthen self-regulation, to resolve ambiguity over the roles and responsibilities of the sector bodies involved and to re-energise our charity membership recruitment strategy," said Colin Lloyd, chair of the FRSB. "The provision of a strong regulatory scheme for fundraising is reliant upon the development of comprehensive industry standards and a robust statutory framework for charity law."
