Telephone Preference Service
This is the UK's only official 'Do Not Call' register for landline and mobile number'. It allows people and businesses to opt out of unsolicited live sales and marketing calls. It is free and quick to register a telephone number.
This will not solve all your problems of 'Cold Calls' - for example calls from overseas are not covered - but it could make a big difference.

TIP If someone Cold Calls you, don't get into conversation with them. Just put the phone down.
