I just noticed those idiots at PlutoTV have removed there British Comedy Channel. A better alternative is XPTV'S: XPTVUK
It can be viewed on the Stream on the budget showcase app on ROKU and go to XPTV.
Among the line up: Fawlty Towers, Benny Hill, Only fools and horses, Father Ted, Are you being served? , Monty Python just to name a few.

It’s ashamed that Pluto TV decide not to continue broadcast the channel of UK sitcoms

XPTVUK is much better anyway and they don't air the same flipping ad's every 5/10 minutes constantly.
