Extra funding

Hi, I'm aware that for funding it's length of course +1year. A couple years back I studied at uni and dropped out after a couple months. Now I'm back studying a degree with a foundation year included so 4 years. However, I'm not particularly fond of this uni and plan on completing my foundation year but was wondering if I were to switch to a different uni next year and then start from year one would I then be only eligible for 2 years funding? Would compelling reasons for extra finance still be valid even if I'd completed my foundation year and hadn't dropped out?
