Will I be entitled to student finance for a foundation year if I've already graduated

Title doesn't allow me to explain the whole situation. I'm thinking about doing a foundation course at a different university once I graduate but am worried about finances. I've received the full maintenance loan for my current uni, does this mean if I applied for foundation somewhere else that I wouldn't be entitled to funding? I don't plan to drop out of my current course, I was thinking of doing the foundation after I graduate. I know student finance doesn't fund a second degree but I don't know if that's different for foundations? If anyone knows how it works I'd greatly appreciate an explanation because it will impact which uni I pick because my family aren't financially stable and student finance has been my life saver so far
