A guide to the fundraising preference service. The Fundraising Preference Service (FPS) is a website-based service operated by the Fundraising Regulator. It allows members of the public to end direct marketing communications from specified charities. The service has been developed to give the public greater control over the communications that they choose to receive from charities. A supporting helpline is also available to help those who cannot access the service online: 0300 3033 517.
