The London 2018 World Chess Championship live coverage sources Which TV channels are going to stream the WCC? Preferably with English commentary. (With live video from the playing board, not only the moves).
I believe the live video footage is restricted to the official broadcast and you probably have to pay to get access to it.
The footage aside, the games will be broadcasted live on chess24 for free (even without an account) with a phenomenal team of commentators, namely, Peter Svidler, Sopiko Guramishvili, Alexander Grischuk, Anish Giri for the English commentary and there will also be separate commentaries in Spanish and German covering each round.
