I find that most good art programmes on TV tend to be on BBC4 but keep an eye because other channels occasionally surprise me.
I do try to keep all this information accurate but due to human error as well as change of programming etc I cannot be held accountable for any inaccuracies. Please also note that I haven't included repeats which are usually later the same evening and often include sign language
Art on TV
If There is nothing on Live TV and you don't want to be starved of Art 'on the box', There is plenty to see on Amazon Prime, in the form of both Art films and Documentaries. Also Try BBC IPlayer for the programmes you may have missed. In addition, whilst in quarantine, Many major galleries are offering free online exhibitions.
Good Luck 👍
