A text message system is being used to alert graduates that they are close to paying off their student loans.
The system follows criticism of the Student Loans Company (SLC) that graduates continue to make contributions, even after their loan has been paid off.
The texts invite people to move to a direct debit scheme, instead of money taken from a wage packet, and means that their repayments stop immediately when their loan is repaid.
"Customers should keep their contact details up to date on their online account. This means we can get in touch when they are within 23 months of repaying their balance in full to invite them onto the direct debit scheme," said Steven Darling, from the SLC.
If they continue to pay through PAYE then payments generally continue until the end of the tax year and they then get a refund of the overpayment.
The SLC texted 30,000 customers in the last month.
