What they ask for
Contact page carries a form whose subject categories are "General Enquiry", "Advertise With Us", "Show Pitch", "Technical Issue", "Press / Media", "Volunteer" and "Other" - there is no music-submission category. Studio 023 8023 50 55 and WhatsApp 07759 796 339 also listed.
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.
