The earliest you’ll start repaying your loan is from the April after you leave your course and only then if your annual income is over the minimum threshold (currently £26,575). The amount you'll repay will depend on your earnings and not the amount borrowed.
You'll repay 9% of your annual income over £26,575 or more per year. If your income falls below £26,575 a year, for any reason, repayments will stop until your income rises above the threshold again.
If you want to make additional repayments you can do so at anytime by debit card, cheque, postal order or direct debit and will not incur any additional charges for doing so.
