I applied for student finance in June but I got a letter through the post the other day saying I wasn't getting any loans, so I think I must have filled it out incorrectly. How do I change my application so I get the student fees and accomadation loans?

yes it many be some incomplete form or due to some missing information.So you have to consult with bank officers.

Call your financial aid officer and request a meeting to discuss your application. While you are waiting for a meeting, review your copy of your FAFSA to see if you see any mistakes. If need be, you can appeal.

Which country are you in?

Consult the person who you had applied and then ask for the application, tell him to find out if there are any errors present.Ifno ask the reason why it was not sanctioned and ask him the process how to sanction it.
