Can we just clear up a pointh here. You don't need a TV licence to own a TV receiver. You need a TV licence to watch TV programmes at the point they are broadcast i.e. watching the 6pm news at 6pm, or to watch content via BBC iPlayer. That's it.
I have a TV but have not paid the licence fee for 6 years as I do not watch either iPlayer or TV at the time it is broadcast. I am quite happily entitled to play on my PS4, stream content from All4 and Netflix and watch DVDs and such like without a TV licence.
Yes I have had the Crapita goons round on a couple of occasions, but a swift "p**s off" is all it takes to make them go away.
