Graduates have been paying back extra on their student loans due to a Student Loans Company error.
Student loan repayments have continued for some ex-students even though they have completed their payment plan.
Over £15 million has been overpaid by ex-students to the Student Loans Company, according to new research revealed by Which?
The study found that almost 60,000 people are awaiting refunds from the SLC after payments were taken from their accounts despite that fact that they had paid back their student loans in full. Some ex-students were even making repayments up to 11 months after their loan has been repaid.
