Uh, the TV licence covers people who watch live TV broadcasts in the UK (including watching the internet simulcast of said broadcasts and using the BBC's iPlayer catchup service).
If your household isn't doing any of that, you don't need a TV license. The license is basically a tax on watching TV that funds the BBC. What more explanation do you need?
