Student Funding with a retired parent

Hello, I am currently enrolled on an undergraduate course and receiving the non-means tested student loan. At the time of applying I wasn't too sure on where I would stand in terms of applying so just went for the simplest option.

My situation is that I'm 23, my father is retired and has been for about 10 years, and my mother is not in the picture and has never been my primary care giver. My father is an EU citizen and receives an Italian pension.

Would I be entitled to any extra funding given my situation and if I am, how would I go about arranging things and what proof would I need?
