Martin Lewis says students who enrolled after 2012 are set to repay up to £110 more each year due to Government tweaks to how student loans are handled.
Last week the Government announced student loan repayment thresholds will be frozen from April 6 after ministers scrapped plans to raise them by 4.6%.
The changes mean some graduates will repay £3,000 more over the 30 years they have to pay back their student loans.
