I just looked it up on Money Saving Expert:
If you don't watch or record live TV or BBC iPlayer and only use other catch-up services or streaming services, you may not need a TV licence at all.
TV licences are only needed to watch or record TV at the same time as it's broadcast, or to watch the iPlayer.
So watching catch-up or on-demand TV using services such as Netflix, Amazon or Now TV, or catch-up services such as All 4 or the ITV Hub, doesn't require a TV licence.
The exceptions are if you're watching the iPlayer, or using other catch-up services to watch live TV.
