The Treasury is conducting a review of student loan repayment after a row over terms.
The government will issue more straightforward guidance on repayments in England.
The review follows a dispute over loan conditions and repayment obligations.
Burnham has opposed Budget reforms.
Labour has left the door open to a repayment U-turn after a widely reported £200bn mis-selling scandal.
The reported figure comes from claims that borrowers were given misleading information about their borrowing.
No final decision has been announced.
The review is still under way.
