Finance advice for my current University situation

Hi, I am currently studying Computer Science and Mathematics BSc, I failed my first year (34%) due to circumstances beyond my control (two accepted mitigating circumstances claims) and I am thinking about resitting the entire year again with attendance. I am however thinking about how I am going to cover this financially. Last year I completed a foundation year before entering my degree, and I wish to do a masters degree after graduating.

Can somebody please explain how postgraduate funding works in contrast to undergraduate, and will I be able to claim an extra year of funding for resitting next year with attendance?

Thank you
