Unless you e-mailed/wrote to/phoned student finance, and got your September 2009 year nullified due to mitigating circumstances, you will need to fund the first year yourself, then the next 3 years will be funded by student finance. If you can apply for compelling personal reasons retrospectively, you will be ok, but I am in a situation where I am needing to take time out, and being advised to apply for CPR now just in case I ever need the extra year, even though I still have my +1 year of funding left.
Best thing to do is phone student finance and ask.
