transferring university?

Im starting first year Radiotherapy at UWE however would like to see if there is any possibility at all transferring to a RG university for 2nd year? Im trying to look into rules for transferring into Cardiff university as it is close and cheaper to live there however I cannot find anything. I understand that quite a few universities do not allow transfers for health profession degrees so this is more like a what if I could situation.

Not a hope. Its an accredited degree and the whole degree has to be done at one Uni to ensure you have covered the entire syllabus - because different Unis may do topics in a different order, have different placement timings etc.
There is no 'better' Uni for Radiotherapy. You will do exactly the same degree wherever you go - and the NHS wont care where you trained and neither will your future patients.
