The Telephone Preference Service (TPS) helps you to make sure your telephone number is no longer available to organisations who may telephone you with offers and information you do not wish to receive.
Under Government legislation introduced on 1 May 1999 It is unlawful to make unsolicited direct marketing calls to individuals who have indicated that they do not want to receive such calls.
You can either do this by contacting companies directly and asking them not to phone you or you can register with a central service (The Telephone Preference Service) to stop all such calls.
The term individual includes consumers at their residential address, sole traders and, except in Scotland, partnerships.
It is free to register with the service.
