You need a UK TV licence for any live TV - not matter which UK company transmits it.
Not sure where the line is drawn if you only use satellite, or live streaming, to watch stations originating outside the UK. I suspect you still need a TV licence.
However it was said the other day that the change will only apply to BBC iPlayer. Apparently it will NOT require a licence for the ITV, C4 etc catch-up services.
