Im sorry to say this but the only thing you need a TV licence for is the channels that dont have breaks (like the BBC channels) i know this as just 2 days ago i had a tv licence guy come over and we had a good long chat about this and i asked him this and i quote "what exactly is a tv licence needed for, is it just for the channels that dont have adverts?" tv guy "Yes, thats exactly it" me "so me living with my ex best friend haveing a tv just to play computer on wouldnt need a tv licence?" tv guy "yes exactly that, but we would have to make several checks to make sure you were not watching the aformentioned channels" me "ok thanks" obviously the reason i asked is there for you to see.
