The pluto list that is available below works quite well and updated a few times a day.
I do believe however that it is CAN/US only but I could be wrong.
Code:
Pluto Playlist: https://nocords.xyz/pluto/playlist.m3u
For Pluto EPG: https://nocords.xyz/pluto/epg.xml
If you wanted to start Pluto channel numbers at 5000:

** disclaimer: Info above comes from the "channels" community
If prefer to pull yourself, there is a docker image which will allow you to do just that. If I recall, the docker image will pull the channels that would be available in your region. So if you want UK channels, put it behind a VPN connected to UK. Probably not too difficult to do with a docker compose combined with a vpn docker image.

But the list does not change too frequently. I have a list from over a year ago, and at least the channels I watch, they still work from the original list.
