If you have the Freeview aerial plugged in I believe (as I have no way to check for you), channel 42 (or 52?), should be Great! Movies Christmas, or it will be if it hasn't changed yet from Great! Movies Classic.
Great Movies Christmas is only available on a Local mux. So basically, if you can receive Local TV on channel 7 or 8 you're in luck................ Otherwise, the answer is no.
@Radfordlc - You can check now as the channel began broadcasting again last month, September.
Great Movies - Christmas 2022
Freeview Channel 52 (TV Guide | Freeview)
Sky Cinema/Sky Cinema on demand normally start Christmas movies sometime in November. If you got Sky Cinema.
Disney + in the last few weeks has started putting up a few Christmas movies if you get that.
Netfilx and Prime Video will be due to start putting up Christmas movies soon. If you got any of them.
Channel 5 has started showing some Christmas movies on Saturday afternoons, They are showing Christmas in Dollywood staring Dolly Parton this Saturday afternoon. Seen it on Netflix last year and it is worth a watch.
Movies 24 is good at showing Christmas movies but its no longer on BT TV and is not on Now(Now TV).
I do get the local mux on Freeview but at times its a weak signal and almost unwatchable in very bad weather.
