Student finance gone up for second year

Do you now have any siblings at uni?

Nope! My sister has just finished her third year in fact, but I don't think that had a great deal of impact on my loan previously as it was an NHS course and she was living at home with a load of bursaries

I must also add the rise in size of loan is because they have now given me a grant. I didn't have one last year.

If your household income has decreased a little, you'd get a bit more. But not a huge amount. I assume that you weren't living at home last year and decided to move out ths year? That would only impact on the amount of loan you can get.
