Student finance- sandwich years

I've applied to study Biomedical Science at university and i am planning on taking a sandwich year (to work in the NHS), however when applying for my degree I couldn't apply for a 4 year course, as it was only the 3 year course available (although they did recommend taking a sandwich year which you would apply for during the course). On student finance, I have to choose a course- either the three year course or the four year course (sandwich). So which would I choose, as I couldn't apply on UCAS for the 4 years, but I am planning on doing it??
