For most NHS professionals, student loan repayments represent a significant, non-negotiable monthly deduction that sits alongside tax and National Insurance. As we enter the 2026/27 tax year, the landscape has shifted with the introduction of first-time repayments for those on Plan 5 and adjusted thresholds for older plans.
Because student loan deductions are calculated on your gross pay, your total earnings before pension and tax are removed, the impact on your take-home pay can be much higher than many staff anticipate. Understanding how these plans interact with your Agenda for Change salary is the only way to avoid surprises on your monthly payslip.
The Introduction of Plan 5 Repayments
April 2026 marks a major milestone in UK student finance: the first ever repayments for borrowers on Plan 5. This plan applies to students who started undergraduate courses in England from August 2023 onwards.
Unlike previous plans, Plan 5 has a lower repayment threshold of £25,000. While the interest rate is lower, fixed at RPI inflation, the repayment period has been extended to 40 years. For a Band 5 nurse on the entry-level salary of £32,073, this means a monthly deduction begins almost immediately upon starting their substantive role.
2026/27 Thresholds for Plans 1, 2, and 4
Each repayment plan has its own buffer zone. You only pay 9% on the earnings that exceed these specific figures:
- Plan 1: For those who started their course before September 2012. The 2026/27 threshold is £26,900.
- Plan 2: For undergraduate students from England or Wales who started between 2012 and 2023. The threshold for 2026/27 is £29,385.
- Plan 4: This applies to Scottish students via SAAS. It retains the highest threshold of £33,795.
- Postgraduate Loan: If you took a Master’s or Doctoral loan, you pay an additional 6% on everything you earn over £21,000.
The Gross Pay Calculation Reality
A common point of frustration for NHS staff is that student loan repayments do not benefit from the same tax relief as pension contributions. While your NHS Pension contributions are taken from your pay before tax is calculated, your student loan is calculated on your total gross pay.
This means if you receive a High Cost Area Supplement or recruitment premiums, your student loan repayment increases. For example, a Band 6 nurse in London will pay significantly more in student loan than a Band 6 nurse in a Fringe zone, even if their basic pay is identical, because the London Weighting pushes their total gross income higher.
Stacked Loans: The 15% Deduction
If you have both an undergraduate loan, such as Plan 2, and a Postgraduate Loan, the Student Loans Company stacks the deductions.
- You pay 9% on earnings over your undergraduate threshold.
- You pay 6% on earnings over £21,000 for your postgraduate loan.
For staff in higher bands, such as 8a and above, this can result in a combined deduction of 15% of their marginal income being diverted to student finance, on top of their 10.7% or 12.5% pension contributions.
How Bank Shifts and Overtime Trigger Payments
Student loan repayments are calculated on a per-pay-period basis. This is critical for NHS staff who work irregular bank shifts or high levels of overtime.
If your substantive pay is usually below the threshold, but a busy month of extra shifts takes your gross pay for that month over the limit, your employer must deduct the student loan for that specific month.
- Overpayments: If your total annual income for the year stays below the yearly threshold, you are entitled to a refund.
- The Catch: This refund is not automatic. You must contact the Student Loans Company at the end of the tax year to reclaim the money.
Impact on Mortgage Affordability
While your student loan does not appear on your credit report, it is a significant factor in mortgage affordability assessments. Because the loan is a committed monthly outgoing, lenders subtract it from your net income when deciding how much you can borrow.
If you are planning to buy a home, it is often more important to look at the take-home figure provided by our Full NHS Pay Calculator than your headline salary, as that is the figure a mortgage lender will ultimately use to assess your lifestyle costs.
