bin doing it for years.

Put on the envelope - return to sender, not known at this address. They pay for the return charge. And send any replied paid cards back blank. They get the message eventually. (Oh - obscure your own address - the postie is not always that alert!)

Of course you have to be invisible on the electoral register, ex-directory, on the TPS register and MPS register and it sure helps if you move to a new address and do all of that from the off. Oh and don't publish your address on the web - use a webform for contacts and hide the e-mail address properly (ask me and I will give you a clue or two).

But you cannot list Mrs Occupier or Mr Householder as a resident.

I still get cold calls - they try all numbers not on the list. They get an earfull and the time it takes is their time.
