Does your student loan affect what you can borrow?
Your balance will not show on your credit report. The deduction on your payslip still lowers your maximum mortgage.
Student loans are not commercial debts, so they do not affect mortgage applications.
Your credit score ignores student loans, but lenders assess net income. Monthly loan deductions reduce the maximum loan size you can be offered.
You have probably been told that your student loan is not standard debt. In one respect, that is true.
UK student loans do not appear on your credit file. Credit reference agencies do not track the balance, and having an outstanding balance will not damage your credit score.
What that advice misses is the affordability calculation.
Lenders assess affordability—a formal check to determine whether you can maintain monthly repayments. To do this, underwriters look at your net income. Net income is your take-home pay after compulsory deductions like tax and pensions.
Your student loan repayment comes off your payslip before the cash reaches your account. Lenders classify this deduction as a committed outgoing, meaning a regular, fixed cost you cannot avoid. A lower net income reduces the total amount you can borrow.
The overall loan balance remains irrelevant to the lender. The deduction on your payslip is what counts.
Check your payslips to confirm your current repayment amount. You can review current repayment rules on GOV.UK to understand how future pay changes could alter those deductions.
