Mail Preference Service Online.
The Mailing Preference Service (MPS) is a free service set up 20 years ago and funded by the direct mail industry to enable consumers to have their names and home addresses in the UK removed from or added to lists used by the industry. It is actively supported by the Royal Mail and all directly involved trade associations and fully supported by The Information Commissioners Office.
The Post Office have an excellent page of advice and links on SCAM MAIL
If you still receive unsolicited mailings despite your registration with the Mailing Preference Service you can use their complaint handling service.
Telephone Preference Service Online.
The Telephone Preference Service (TPS) aims to help make sure your telephone number is no longer available to organisations, including charities and voluntary organisations who may telephone you with offers and information you do not wish to receive. These are the main headings
Register your home or business numbers
Make a complaint,
What is corporate tps?
Check you are registered
Ofcom consumer guide
Or contact TPS
Basically you can do everything you need to do but sadly lots of companies just ignore the TPS and so you still get calls! However as soon as you say you are registered callers usually ring off immediately
The Telephone Preference Service is designed to help to stop unwanted telephone calls. You just submit your number and preferences and you are supposed to be protected for 4 years. Good luck! I have never found that it works but perhaps it does stop some unwanted calls - so why not do it! The only thing that I have found is that if you tell any SPAM callers that you are on the TPS registry they either ring off immediately or apologize profusely - as they are breaking the law.
Facsimile Preference Service Online.
Under Government legislation introduced on 1 May 1999 it is unlawful to send an individual an unsolicited sales and marketing fax without prior permission. Businesses have the opportunity to register fax numbers on which they do not wish to receive direct marketing faxes.
You can do this by registering with the Fax Preference Service. Although this Service is primarily aimed at businesses, as individuals have protection under the legislation, individuals may also register their fax numbers if they wish.
