Endeavour FM serves Boston, Lincolnshire. It is an Ofcom-licensed community station, and this is what it publishes about taking music from artists.

What they ask for
No music submission route posted. Site-wide contact is "[contact on your sheet]" and "Text BOSTON to 80011". The Get Involved page states only that the station exists to "play the best music and bring the community closer through on-air content".
The exact submission address or form is on your sheet, not on this page. That is deliberate: a station that publishes an address for artists should not have it republished where it can be harvested.
Rotation's free sheet is U.S. radio: 1363 stations, none of which has a rule about what country you are in. A UK artist can use it as it stands.
