The NSPCC is to charge charities and voluntary groups up to £195 for accreditation under its new child safety certification scheme.
In return for the fee, charities working with children can have their child protection credentials officially recognised by the NSPCC.
Groups providing performing arts, faith-based, leisure and vocational activities for children and young people are being encouraged to sign up. The scheme costs £195 for charities and £125 for groups with fewer than five full-time staff. Commercial organisations will pay £250.
Fiona Becker, senior consultant with NSPCC Training and Consultancy, said: "We want organisations to consider implementing child protection measures before something goes wrong."
