If never home is never home when the TV Licence inspector calls, then they have no name to send a summons to. If they have no name, then they cant send a summons. However, if you have bought a licence last year which has just lapsed, then they can send you a summons. So once you buy one TV Licence you have to buy one forever, or until you move house.
I do think Rainydays attacks on the original poster were out of order, if people cant afford it, then they should be taken as genuine. By saying its 50c per day, is stupid, you cant save your 50c for a year and then buy your licence. People are entitled to be upset if you call them spongers without knowing their circumstances.
Rainyday states that XXXAnotherPersonXXXX wants to choose what laws they obey. But some people might think it is you who is choosey. On one discussion, you slate people as spongers without a TV Licence, but on another site you berate people who object to the dirt travellers leave behind them. As dumping is clearly against the law, and you are so into upholding the law, why no call everyone who breaks the law a sponger or whatever it is. I know the travellers etc have nothing got to do with TV Licences, but I am just making the point that it is your views which change when suits.
