How Each UK Student Loan Plan Works in 2026-27
Understanding how interest applies across each loan plan helps clarify overall balance growth for borrowers under current UK student finance guidelines.
Plan 1 Student Loan Interest Rates
Plan 1 student loans apply to pre-2012 undergraduate borrowers. Interest is set at RPI or 1% above the Bank of England base rate, whichever figure is lower. Because RPI is 4.1%, the maximum interest rate on Plan 1 loans is 4.1%.
The official announcement confirms that the Plan 1 repayment threshold will rise to £28,005 per year for the tax year running April 6, 2027 to April 5, 2028.
Plan 2 Student Loan Interest Rates
Plan 2 covers undergraduates who enrolled between 2012 and 2023. Under the standard formula, Plan 2 interest can range from RPI to RPI plus 3%. For 2026-27, the maximum rate is capped at 6.0%.
Plan 3 Student Loan Interest Rates
Plan 3 student loans cover postgraduate master’s and doctoral students. Plan 3 interest is normally set at RPI plus 3%. For 2026-27, the maximum rate is capped at 6.0%.
Plan 5 Student Loans
Plan 5 student loans apply to undergraduate students starting higher education courses from August 2023 onwards. The interest rate matches RPI directly at 4.1%, with no additional percentage margin added above inflation.
Mortgage Style Student Loans
For older mortgage-style loans, the interest rate will equal 4.1% from September 1, 2026. The official deferment threshold for mortgage-style loans is set at £44,311 for the same period.
Key Takeaways on UK Student Finance Changes
When reviewing student loan repayment changes announced by the Student Loans Company, borrowers should note several important framework guidelines:
- Market rate protection: Statutory caps limit student loan interest rates in line with the prevailing market rate rules.
- Income-based repayments: Interest accrual affects total outstanding balances, but actual monthly student loan repayments depend strictly on income level above approved plan thresholds. Understanding these costs can also help students planning to study abroad manage their overall education budget.
- Future threshold updates: The Plan 1 threshold change to £28,005 takes effect in April 2027, maintaining predictable payroll processing via HMRC systems.
- Student loan forgiveness: Recent developments in student loan forgiveness for 500,000 borrowers highlight how changes in student debt policies can affect borrowers.
End Note
The official August 10 announcement regarding UK student loan interest rates provides essential clarity for the 2026-27 period.
With RPI set at 4.1% and a strict 6.0% cap safeguarding Plan 2 and Plan 3 borrowers, the updated framework establishes transparent standards across all student finance plans.
