More than 500 charities have signed up to the MyDonate online fundraising service since its launch in April, according to BT.

Charities that have already signed up include Citizens Advice, Save the Children and Scope, joining founding partners Cancer Research UK, NSPCC, Changing Faces, KidsOut, and Women’s Aid.

The MyDonate platform charges neither charities nor donors a subscription or set up fee, and does not take a commission on donations.
