me and my sister are both at the same uni, in first year, i stayed at home and she lived in halls. we both also get full grant/loan and as far as i know i think she only gets a couple of hundred extra than me per term. basically. despite the fact i live at home i still get around £2000 per term, so i'm guessing since you're on full grant/loan as well you'll get the same. And our university gives me and my sister exactly the same bursaries.
i do think its stupid how much you can claim living at home, i get more than some of my friends who live in halls and have to pay stupidly high bills just because their parents earn a better living than mine. It's crazy, but i work as well so i don't feel so guilty getting so much.
