Student Loan Refunds

Why is it that you pay your student loan back based on a monthly threshold. However, you can only get a refund if your annual income is under the annual threshold. In my example, we had some back pay in one month, which pushed me over the threshold for that month only (but wouldn't have if paid monthly), so I had to pay a student loan. I then got a pay rise, so I started paying student loan payments (fair enough). But based on my annual income, I will now have paid more of the loan than I should have, but I can't get the overpayment back as my annual income is over the threshold. In other words, they've taken too much when you look at it annually but won't give it back. Seems very unfair. Any thoughts?

Hi

We have to wait until the end of the year to check your total income received to be able to confirm if any refund is due.

Thank you
