If a person is legally licence free it is astonishing they have to make any kind of effort to escape TV licence worry.
The original question is about the new "calendar deadline letter"......and what to do about it.
Well if they watch live signals its up to them to get a licence.
If they dont ................... do not feel obliged to contact anyone.
Anyone with no TV/ receiving/ recording equipment daft enough to fill in a "opt out" form will also use the 0300 numbers on the letters.
[ And you will be pleased to hear the calls cost no more than the national rate ]
Get on the blower and ask to be put through to the " I have nothing better to do with my money " department.
