As I understand the BBC licencing website I do not need a licence if I do not watch live TV.
From BBC website:
"No TV? Not watching live TV on any channel or service, or BBC programmes on iPlayer? Empty property? You can let us know here by completing a No Licence Needed declaration.
The law says you need to be covered by a TV Licence to:
watch or record programmes as they’re being shown on TV, on any channel
watch or stream programmes live on an online TV service (such as ITV Hub, All 4, YouTube, Amazon Prime Video, Now TV, Sky Go, etc. )
download or watch any BBC programmes on iPlayer.
This applies to any device you use, including a TV, desktop computer, laptop, mobile phone, tablet, games console, digital box or DVD/VHS recorder."
