Hello - while you’re welcome to post here, please be aware that most users in the UK communicate using other methods.
For GB (England, Scotland, and Wales) most traffic is at https://lists.openstreetmap.org/listinfo/talk-gb and IRC irc://irc.oftc.net/osm-gb .
For the island of Ireland, https://lists.openstreetmap.org/listinfo/talk-ie is the relevant mailing list for both the Republic of Ireland and Northern Ireland, although Telegram is also frequently used there.
HTML front-ends for all of the above also exist - for example, via https://irc.openstreetmap.org/ .
