Who Is on Plan 4?
You have a Plan 4 student loan if you are from Scotland and took out a student loan from the academic year 2006/07 onwards. This includes students from other parts of the UK who attended Scottish universities if their loan was issued under Scottish rules. Check your Student Awards Agency Scotland (SAAS) account to confirm your plan type.
How Plan 4 Repayments Are Calculated
You repay 9% of your income above the repayment threshold. For 2025/26, the Plan 4 threshold is £32,745 per year (£2,728.75 per month) — the highest of any UK plan.
Example: If you earn £38,000 per year, you repay 9% of (£38,000 minus £32,745) = 9% of £5,255 = £472.95 per year, or about £39.41 per month.
When Does a Plan 4 Loan Get Written Off?
Your Plan 4 loan is written off 30 years after the April following the year you left your course. The write-off age of 65 does not apply to Plan 4 loans.
Interest on Plan 4 Loans
Like Plan 1, interest on Plan 4 loans is set at the lower of the RPI or the Bank of England base rate plus 1%. This is generally more favourable than the Plan 2 rate.
Frequently Asked Questions
I studied in Scotland — am I definitely on Plan 4?
Not necessarily. Students who studied in Scotland before 2006 may be on Plan 1. Check your SAAS account or your Student Loans Company account to confirm.
Can I have both a Plan 4 and a Postgraduate loan?
Yes. If you completed a Scottish undergraduate degree and then took out a Postgraduate loan, you will repay both simultaneously — Plan 4 at 9% above £32,745 and Postgraduate at 6% above £21,000.
