Child of Migrant Worker age

Hello,

I currently get the EEA child of migrant worker maintenance loan. However, I am soon turning 21 and I am unsure what's going to happen next year. In order to receive the maintenance loan in this situation, do I need to prove my dependency on my parents next year? Or is it enough that I was under 21 on the first academic day of my course (1s year)?

And if I have to prove financial dependency, is proving that my dad pays for my student halls enough?

Thank you
