Basically, everyone in Uk registers with a GP (General Practicioner, sometimes called family doctor; if juts doctor is mentioned, people usually mean GP). Those who need specialist care eg a child with type 1 diabetes, will be refered by GP to a hospital clinic approprate to their needs eg not all hospital diabetes clinics / consultants (usual term for any specialist physician, who leads / co-ordinates a team of other doctors, specialist nurses, dieticians etc) deal with both adults and children, and not all deal with pumps. GPs issue prescriptions for all consumables, usually monthly, but having type 1 diabetes and being a child are both qualifying reasons for free prescriptions ie nothing to pay atthe chemist when you collect your items. However, GPs do hold budgets and may restrict items if consider excessive. I'm not sure how they would deal with someone on a pump who doesn't meet NICE guidelines - assuming you're moving to England - rules are wider for free prescriptions in Wales & Scotland, but tighter for pumps, and they have their own methods of deciding who is elligible for a pump.
