Student Loans: The UK New System is mainly about Plan 5, the repayment plan now affecting many English undergraduate students who started newer courses. The key point is simple: student loan repayment is based on what you earn, not how much you originally borrowed. This guide explains how UK student loans are repaid, what happens through payroll, and what to check so you do not overpay or miss an important update.
What is the UK new system for student loans?
The “new system” usually refers to Plan 5 student loans, which England introduced for many undergraduates from 2023/24. Plan 5 sits alongside older UK student loans, including Plan 1, Plan 2, Plan 4, and Postgraduate Loans, across England today. Because rules differ across UK student loans, confirm your repayment plan before researching thresholds, interest, or write-off periods. Each plan can have different thresholds, interest treatment, and write-off periods, so confirm your plan before making comparisons. (gov.uk)
Under Plan 5, repayments do not work like a credit card, personal loan or overdraft. You do not pay a fixed instalment because your balance is large, and you do not normally have to negotiate monthly repayments yourself if you are employed in the UK. Instead, repayments are triggered by your income and collected through the tax system once you earn above the relevant threshold. (gov.uk)
This matters because the headline debt figure can look intimidating, especially when tuition fees, maintenance loans and interest are added together. For most borrowers, however, day-to-day affordability is driven by earnings. The balance still exists, interest can still be added, and voluntary repayments are possible, but your compulsory payment is calculated from income above the threshold.
How student loan repayment works in practice
Student loan repayment starts when you become due to repay and your income exceeds your plan’s minimum threshold. Employees usually make repayments through salary deductions alongside tax and National Insurance, with each deduction appearing on payslips. Self-employed borrowers and people completing a Self Assessment tax return have HMRC calculate repayments through their return directly. (gov.uk)
The process usually follows these steps:
- You finish or leave your course. You become eligible to repay from the April after you finish or leave, although Plan 5 borrowers were not expected to repay before April 2026 at the earliest. (gov.uk)
- Your income is checked against the threshold. If you earn below the threshold for your plan, no compulsory repayment is due for that pay period.
- A percentage is applied to earnings above the threshold. For Plan 1, Plan 2, Plan 4 and Plan 5, this is 9% of income above the threshold. Postgraduate Loan repayments are 6% above the Postgraduate Loan threshold. (gov.uk)
- The deduction is collected automatically if you are employed. Your employer deducts it through PAYE and HMRC passes repayment information on to the Student Loans Company.
- Your balance is updated. The Student Loans Company manages your account, applies repayments and interest, and provides annual statements and online account information. (gov.uk)
A useful way to think about this is: threshold first, percentage second, balance third. Your loan balance affects how long you may keep repaying, but it does not decide the amount taken from this month’s payslip.
Plan 5 thresholds and a simple example
For the 2026 to 2027 tax year, the Plan 5 repayment threshold is listed as £25,000 a year, £2,083 a month or £480 a week. The repayment rate is 9% of income above that threshold, not 9% of your full salary. (gov.uk)
For example, if you are on Plan 5 and earn £32,000 a year, the calculation is based on the amount above £25,000. That is £7,000 over the annual threshold. Nine per cent of £7,000 is £630 a year, which works out at about £52.50 a month before any payroll rounding.
If your salary is £25,000 or below, there would be no compulsory Plan 5 repayment based on that annual figure.
If bonus, overtime, or a higher-paid month pushes you over a weekly or monthly threshold, deduction may still happen.
You may request a refund after the tax year if annual income stays below your plan’s yearly threshold.

Why your payslip may change from month to month
Student loan deductions can move with your income. If your pay rises, your repayment can rise. If your income drops below the threshold, deductions should stop for that period. This is why graduates in commission-based, seasonal or overtime-heavy jobs may see deductions in some months and not others.
A few common situations can affect repayments:
-
-
- Starting a new job: check the starter checklist carefully so your employer uses the correct student loan plan.
- Getting a bonus: your pay for that month may exceed the monthly threshold, even if your usual salary is lower.
- Changing from employment to self-employment: your repayment may move from payroll deduction to Self Assessment.
- Having more than one loan type: postgraduate repayments can be collected alongside undergraduate repayments, because the postgraduate rate is separate.
-
Leaving the UK for more than three months: you must update your details with the Student Loans Company, as overseas repayment thresholds
Does interest mean you should repay early?
Interest is added to uk student loans, including when you are not working or your income is below the repayment threshold. GOV.UK lists current interest information by plan, and Plan 5 interest is shown separately from older arrangements. Because interest rates and thresholds can change, it is sensible to check your online repayment account before making decisions. (gov.uk)
Whether voluntary repayments are worthwhile depends on your circumstances. There is no penalty for making extra repayments, but paying more does not reduce the compulsory amount taken from your salary next month if you still earn above the threshold. Extra payments mainly reduce the balance, which may help if you are likely to repay the loan in full over time.
For many borrowers, the more important question is not “How big is my balance?” but “Am I likely to clear it before it is written off?” Plan 5 loans are written off 40 years after the April you were first due to repay. That longer period means some people will repay for much of their working life, while others may never clear the balance in full through compulsory repayments alone. (gov.uk)
What to check before you make financial decisions
The UK student loans system is designed to run in the background, but it is still worth being active about your account. Small admin errors can lead to incorrect deductions, missed updates or repayments being applied later than expected.
Use this quick checklist:
- Confirm your repayment plan through your student finance or repayment account.
- Check your payslip to make sure the deduction appears only when expected and under the right plan.
- Update your details if you move, change email address, become self-employed or go overseas for more than three months.
- Keep evidence such as payslips, P60s and Self Assessment records.
- Review before overpaying if you are thinking about voluntary repayments, especially if you have other debts or savings goals.
- Check official guidance each tax year because thresholds and rates may change.
The biggest mistake is treating student loan repayment like ordinary consumer debt without looking at the rules. It is a real financial obligation, but its income-linked structure makes it behave differently from most borrowing.
The main takeaway
Student Loans: The UK New System is best understood as an income-based repayment system, not a fixed debt repayment schedule. If you are on Plan 5, you repay 9% of income above the relevant threshold, usually through PAYE if employed or through Self Assessment if self-employed. Your balance and interest matter, but they do not directly set your monthly repayment.
Before you act, check your repayment plan, review your latest payslip or online account, and compare any voluntary repayment decision with your wider budget. If anything looks wrong, update your details with the Student Loans Company or speak to your payroll team so your student loan repayment is being handled correctly.
