Because a donation is a gift rather than a purchase, consumer cancellation rights do not apply. That said, charities generally do refund clear errors, and the Fundraising Regulator expects them to have a policy covering:
- duplicate or mistaken payments,
- donations made by someone without authority to give,
- gifts made under undue pressure.
Contact the charity directly and quickly — refunds become harder once Gift Aid has been claimed and reported to HMRC.
To stop a recurring gift, cancel with the charity first; if that fails, cancel the Direct Debit or card mandate with your bank. Under the Direct Debit Guarantee your bank must refund payments taken in error.
