I'm in the same position at the moment, it's pretty much a case of doing the exact same thing as last year. SFE fund up to (I think) 4 years, so as long as you've only done a year and it's a 3 year course, there's no problem with that. I've literally just started filling in a new UCAS form and messaged the tutor of my current course, and it seems pretty straightforward from there. I know a few of my friends did a year on one course and simply asked to change onto another course in their university, so if you're wanting to study at the same uni, it might be simpler? However, if it's a popular course as was said above, UCAS is probably the better route to go down.
