Unlike commercial mortgages or credit card loans, UK student loans function as an income-contingent graduate tax that automatically self-destructs after a statutory time limit. If your earnings never clear your balance before your cancellation date arrives, the government completely writes off the remaining debt. Here is when each plan writes off, how repayment thresholds work in 2026/27, and how to verify your write-off date.
- Plan 1 (Pre-2012 / NI & Wales): Threshold £26,065. Written off 25 years after the April you left university (or at age 65 if you started before September 2006).
- Plan 2 (2012–2023 England & Wales): Threshold £29,385. Written off exactly 30 years after the April following graduation. Over 75% of graduates will reach write-off without clearing their balance.
- Plan 4 (Scottish Students): Threshold £33,795. Written off 30 years after leaving course or at age 65 (whichever is earlier).
- Plan 5 (Post-Aug 2023 England): Threshold £25,000. Written off after 40 years.
- Postgraduate Master’s Loan: Threshold £21,000 (6% repayment rate). Written off 30 years after leaving course.

1. The Clock Starts: The April After You Leave University
A widespread misconception is that your student loan cancellation clock starts ticking on the day you graduate. In statutory reality, under Education (Student Loans) Regulations, you first become liable to repay in the statutory April following your departure from university.
For example, if you finished your degree in June 2020, your repayment liability officially commenced on 6 April 2021. For Plan 2 borrowers, your 30-year clock expires in April 2051, regardless of whether you worked, traveled, or were unemployed during that time.
2. Complete Write-Off Rules by Plan
| Plan Type | Qualifying Criteria | 2026/27 Threshold | Repayment Rate | Write-Off Trigger |
|---|---|---|---|---|
| Plan 1 (Pre-2006) | Started course before Sep 2006 | £26,065 | 9% | When borrower turns age 65 |
| Plan 1 (2006–2011) | Started course between Sep 2006 & Aug 2011 | £26,065 | 9% | 25 years after statutory April start |
| Plan 2 | Sep 2012 – Jul 2023 (England & Wales) | £29,385 | 9% | 30 years after statutory April start |
| Plan 4 (Scotland) | Scottish undergraduate students | £33,795 | 9% | 30 years after April start or age 65 |
| Plan 5 | Post-1 August 2023 (England) | £25,000 | 9% | 40 years after statutory April start |
| Postgraduate | Master’s and Doctoral loans (E&W) | £21,000 | 6% | 30 years after statutory April start |
3. Worked Hand-Check Example: Plan 2 on £32,000 Salary
To verify the statutory arithmetic for Plan 2 deductions in the 2026/27 tax year:
Plan 2 Hand-Check Proof:
- Gross Salary: £32,000.00.
- Plan 2 Statutory Threshold (2026/27): £29,385.00.
- Earnings above threshold: £32,000.00 − £29,385.00 = £2,615.00.
- Repayment rate: 9.0%.
- Annual Repayment: £2,615.00 × 9% = £235.35 per year.
- Monthly Deduction: £235.35 ÷ 12 = £19.61 per month.
If this borrower has a balance of £50,000 accruing RPI interest, their annual interest exceeds £2,500/year, meaning their balance will grow every year despite making payments. When their 30-year term concludes, their entire remaining balance (over £80,000) will be written off in full.
4. Why Voluntarily Overpaying Plan 2 Is Almost Always a Mistake
Because Plan 2 write-off is virtually guaranteed for middle earners, treating your student loan like a commercial credit balance is costly. Any voluntary lump-sum repayment you make comes directly out of your bank account. If your salary would never have paid off the full loan before the 30-year write-off date, your voluntary repayment does not save you a penny in future deductions — it is simply lost cash.

Frequently Asked Questions (2026/27)
Does the UK student loan ever get written off?
Yes. Every UK student loan plan includes a statutory cancellation clause where any remaining principal and accrued interest are completely cancelled (written off) by the government tax-free after a set number of years, or when the borrower reaches age 65, depending on the plan.
How many years until a student loan is wiped off?
The cancellation period depends on your specific repayment plan: Plan 1 is cancelled after 25 years (or at age 65 for pre-2006 loans); Plan 2 is cancelled after 30 years; Plan 4 (Scotland) is cancelled after 30 years (or at age 65); Plan 5 is cancelled after 40 years; and Postgraduate loans are cancelled after 30 years.
Does Plan 2 student loan get wiped?
Yes. Plan 2 loans (for undergraduate students from England and Wales who started university between 1 September 2012 and 31 July 2023) are automatically cancelled exactly 30 years after the April following graduation or course departure.
Does a UK student loan get wiped after 30 years?
Yes for Plan 2, Plan 4, and Postgraduate master’s loans. Under current Student Loans Company rules, Plan 2 and Postgraduate loans are written off 30 years after you were first due to repay. Plan 5 loans, however, have a 40-year repayment term before cancellation.
Do student loans get wiped after 25 years in the UK?
Only Plan 1 loans taken out by students who started university between September 2006 and August 2011 are wiped after 25 years. Older Plan 1 loans (pre-2006) are written off when the borrower turns 65, while newer plans require 30 to 40 years.
Are student loans written off at 65?
Plan 1 loans taken out before 1 September 2006 (students from England, Wales, or Northern Ireland) and Scottish Plan 4 loans are cancelled when you turn 65 if that occurs before the 30-year term ends. For Plan 2, Plan 5, and Postgraduate loans, write-off is based strictly on years elapsed rather than your age.
Are student loans written off after 10 years?
No. There is no UK student loan plan that writes off debt after 10 years. UK terms range from 25 years (Plan 1 post-2006), 30 years (Plan 2, Plan 4, Postgraduate), up to 40 years (Plan 5).
What happens if you never earn enough to pay back your student loan?
If your annual earnings never exceed your plan’s statutory repayment threshold (£29,385 for Plan 2, £25,000 for Plan 5, £26,065 for Plan 1, £33,795 for Plan 4), you make zero repayments. When the write-off period ends, the entire loan balance and all accumulated interest are cancelled completely, with no tax liability or negative impact on your credit rating.
What happens if you never pay off a student loan?
If you make statutory repayments through PAYE or Self Assessment but your payments do not cover the interest or principal before your write-off deadline, the remaining balance is written off by the government. The debt simply disappears and cannot be pursued.
Will I ever pay off my student loan?
Official government forecasting by the Department for Education indicates that only around 20% to 25% of Plan 2 borrowers will repay their loans in full. Most Plan 2 graduates treat repayments as a 9% graduate tax that terminates after 30 years. Conversely, around 50% to 60% of Plan 5 borrowers are projected to repay in full due to the 40-year term.
Is it ever worth paying off a student loan in the UK?
For most Plan 2 borrowers, making voluntary extra repayments is financially irrational because the loan balance will be written off anyway. Overpaying simply means giving away cash you will never get back. Paying off early is only advantageous for sustained high earners whose salary will clear the balance well before the 30-year write-off date.
Should I repay my student loan in full plan 2?
In the vast majority of cases, no. Because Plan 2 debt is written off after 30 years, paying it off in full means repaying money you would otherwise never have had to pay. Only individuals earning consistently above £65,000 to £75,000 early in their careers who are certain to clear the debt before year 30 should consider voluntary repayments.
What happens if you don’t pay back student loans in the UK?
Repayments are deducted automatically through PAYE alongside income tax, so UK employees cannot legally evade payments while earning above the threshold. If you move abroad, you must complete an overseas assessment; failure to do so can result in HMRC penalties and fixed default repayment charges.
What percent of people don’t pay back student loans?
According to the UK Government and Institute for Fiscal Studies (IFS), approximately 75% to 80% of Plan 2 university graduates will not fully repay their loan before the 30-year write-off date, leaving the government to write off tens of billions of pounds in student debt annually.
