Student Loans and Mortgage Affordability
Student loan repayments are treated as a regular monthly deduction by most mortgage lenders — meaning they reduce the income available for mortgage affordability calculations.
How lenders typically treat student loans:
- Many lenders deduct actual student loan repayments from disposable income when stress-testing affordability
- Some lenders use the monthly repayment amount; others assume 9% of income above the threshold
- A higher-earning borrower on Plan 2 earning £50,000 would make repayments of approximately £173/month — this reduces the mortgage they can borrow
If you are close to the repayment threshold and know your loan balance will be written off soon (Plan 2: 30 years from April after graduation; Plan 5: 40 years), this may factor into a lender’s assessment. Speak to a mortgage broker if student loan repayments are affecting your affordability significantly.
Should You Make Voluntary Overpayments?
For most borrowers on Plan 2 or Plan 5, voluntary overpayments are generally not recommended because:
- The loan is written off after a set period regardless of the balance
- Higher-earning graduates who will repay in full may benefit from overpaying — but only if the interest rate is above alternative savings/investment returns
- Lower-to-average earners will rarely repay the full balance before write-off — voluntary overpayments effectively become a gift to the government
When voluntary overpayments can make sense:
- You are on Plan 1 (very low or zero interest rate — worth clearing if you have spare cash)
- You are a high earner on Plan 2 and your projected lifetime repayments exceed the outstanding balance
- You have a postgraduate loan at a rate above your savings rate

If You Think You Have Overpaid
Student Loan Company (SLC) overpayments happen when PAYE repayments continue after the account should have been cleared — often due to HMRC reporting delays. If you believe you have overpaid:
- Contact the SLC at slc.co.uk or 0300 100 0611
- SLC will request your repayment history from HMRC
- Refunds are typically processed within 4–6 weeks of the overpayment being confirmed
SLC is required to refund any overpayment — do not ignore it if you believe your loan should have been cleared.
