You should be able to get a loan to cover your tuition fees, and one to cover your living expenses. I'm not quite sure what else you mean, but if you are from a household which falls below a certain income band you will be eligible for non-repayable grants and perhaps bursaries from the vet schools. I think most also offer scholarships for exceptional candidates but I wouldn't pin your hopes on getting one because sometimes you can be unpleasantly surprised with uni's decisions. Certainly it wouldn't be realistic to expect to fund your studies from a scholarship, or any other means unless you are a mature student who has worked in a well paid job for several years and saved like a monk the whole time. Tution fees are £3000 a year and living cost loans vary between £2800 and £4500 a year, so all in all a veterinary medicine degree would cost you in the region of £29,000 and £45,000 depending on whether you do the extra year at Cambridge. Most people are not expected to have access to such a colossal amount of money before they start studying so the idea is you pay it back when you are in a job and earning over £15,000.
