Smaller charities are signing up to FRSB but larger ones remain elusive.

Growing membership has led to significantly increased administration costs for the Fundraising Standards Board(FRSB), its annual report shows.

The report, out this week, shows 225 smaller organisations signed up to fundraising self-regulation last year, which created an £80,000 increase in administration costs.

Membership is now 1,547 with four out of five new member charities having an income of less than £1m a year.

Growing the sector’s public commitment to best practice and accountability...is critical

One-third of FRSB members are charities with income of between £100,000 and £1m a year, and just 83 charities turning over more than £10m are part of the scheme.

Charities reporting income above £50m per annum are subject to a £5,000 annual fee.

Just under 100 fundraising suppliers – organisations carrying out fundraising on behalf of a charity – have signed up with the FRSB

The FRSB is now attempting to address this balance and recruit more of the larger fundraising charities to its membership.

In the coming year, the FRSB says it will focus on signing up charities with income of more than £1m.

FRSB board chair Colin Lloyd added: “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.

"This continues as does the FRSB’s role in growing the sector’s public commitment to best practice and accountability which is critical.”
