"If you watch live TV over iplayer or on a website, you still need a license though. I'd imagine if you have a TV with a tuner in it capable of picking up telly signals the effort in convincing the TV licensing bods you don't watch any live TV is probably more effort than the £145 saving. Pointing out you don't watch live telly to the bailiffs or the chaps in the court when the summons arrives is probably a lot of aggro too?"
Thing is, I don't actually bother convincing them of anything; thanks to the presumption of innocence, it's THEIR job to prove their case through some sort of judicial process, not mine. I probably could make their lives easier by being a bit more open, but I like the idea of wasting the time of an organisation of which I disapprove.
I don't have a TV (not really relevant anyway), but they don't know that. I've had them come to the door, and the response is "No thank you, I don't need one.", before turning off the intercom, which takes seconds. Hardly worthy of the term "effort".
The threatening letters (full of "could"s, "may"s, "up to"s, etc., nothing formal like a court summons) get filed in the recycling. They can't be bothered taking anything further when there are easy victims who actually invite the inspectors in, or answer their questions.
