Don’t they get loans for the uni fees ?
They do. It's not the fees but the living costs that are crippling. Both of ours got minimum loans but their rent was £2500 / year more than the loan without food, books, expenses on top. Then deposits for the next year's housing, paid at about Xmas, plus half rent during the summer when no maintenance loan paid etc etc.
We still help our son out financially now because he's done a PGCE and now in his NQT year, living away from home but earning nowhere near enough to live on. We've resigned ourselves to it now. We're worse off than when they both lived here because we are supporting 3 households right now.
