Not sure if you guys know about this, but you can register your address and phone number with the Mail Preference Service and Telephone Preference Service to help cut down on the amount of rubbish forced upon you...

To quote from their website:
It can take up to 6 months for the amount of (addressed) junk mail to be reduced and it seemed to work as I registered my folks place ages ago. The telephone one works too, just a shame it doesn't stop those flipping scam calls that originate outside the UK.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 Office of the Information Commissioner.
