I remember a few major problems.
First time, I bought one for my room within my student flat on direct debit. They started double-billing me for the first six months, and I didn't notice, which led to me having to pay an overdraft charge. I then stopped payments after six months (having paid for a year) and they started pestering me immediately. No action taken, but a lot of paper wasted on annoying letters.
Second time, I bought a licence for the communal room (meaning the kitchen) because I was the only one in the flat with a telly and there was an aerial point there. Of course, everyone else in the flat watched it, but nobody chipped in... :roll: Anyway, the licensing agency immediately started demanding that I get a licence for my room (where the telly wasn't). At first, I ignored it, then they started threatening to send an inspector round. I rang them to explain, and they backed off for a bit, but then started again. No inspector turned up, but I wonder what they would have done if they turned up to find nothing. An expensive waste of time. At least I paid by cheque this time.
There was a repeat performance the next year, for the same flat.
Finally, I tried to buy one for my room when I did my masters' (different type of flat). They assumed I was buying one for the whole house, and I just ignored it. There was no further action, and I was free to move the telly from room to room.
SO
How do they know which room it's in?
What if somebody borrows it for one night?
If they do an inspection and find that everything is in order (no television or anything else in the flat) do they charge you?
