Yes and no, as with most long term plans (4 years+ in this case) I have a few options in mind but it really does depend on the circumstances a few years from now. The most important thing, in my opinion, is that you get the opportunity to spend 4 years in a thought provoking environment, maybe make new friends or at least meet other people also out to make a positive change in their lives.
As for the post graduation options I have in mind, without actually investigating if the university can provide relevant placements (which I believe Kingston does as part of a sandwich year for Biology), I believe the NHS and some other institutes do have relevant research positions for biology graduates.
Then there is the option of going into medicine, but at a later stage due to having already studied a lot of overlapping material. However most medical courses will require own finances for tuition fees, so that will need to be considered at the time, I think there are some national shortage courses that are NHS/government funded but naturally that changes periodically.
There's also quite a few graduate schemes, or you could always get into further post graduate education, you might have to contribute some finances but there is a lot of financial help available in the form of scholarships and bursaries.
