Some labels do organise tours but it is unlikely that they will do this for a band that is unknown to them - so I wouldn’t rely on that avenue. I’d also be wary of it because there are a few shady companies who will be looking to make a tidy profit and screw you over on this sort of thing. First point is, as it’s been mentioned, don’t expect to make any money. Bands who have been touring the UK for years barely make any money…UK shows generally do not pay well at all for bands below the headliners.
Additionally, if you are fresh out the blocks and don’t already have any established links to the UK (either fans, friends or other bands) I think to be honest you may struggle to get gigs at all - with the live music climate how it is at the moment, I think many promoters would be wary of putting on a band from another country without an obvious fanbase.
You may get lucky but I think your best way through is trying to make some contacts first, get people interested in your music in the UK and then see if you can get them to help you. 99% of promoters will ignore emails from bands they haven’t already heard of, sadly, because they get so many of them.
If you want to dm a link to your music I can have a listen and see if I know anyone I can put you in touch with.
