How do i stop advertising, research companies etc phoning my home phone in the UK?

Simple, you need to go to the TPS (telephone preference service) and register your details with them. Ofcom regulations say that companies cold calling need to check all numbers with the TPS and if you are on it then you should not get calls.

Some smaller companies might not check this so you should complain when they call and ask to be added to their “Do Not Call List” manually. Companies can also get around this if you’ve purchased something from them in the past and class you as an existing customer, therefore will not need to use the TPS, however, as above just ask to be added to their “Do Not Call List”.

This will all help to halt the calls but will not be immediate.
