Best 2-year fixed rate ISAs for secure medium-term savings
The best 2-year fixed rate ISA locks in competitive interest at around 4.16% AER, providing tax-free growth for your savings over the medium term.

Providers like Shawbrook Bank and Yorkshire Building Society lead with top rates, beating easy-access alternatives for those committed to a two-year term.
Fixed rate ISAs offer stability by securing a rate at the outset, protecting against drops in the Bank of England base rate. Unlike variable easy-access cash ISAs, which currently top 4.51% but could decline, a 2-year fixed rate isa ensures predictable income. For the 2025/26 tax year, you can invest up to £20,000 in a cash ISA, with interest compounding tax-free.
What is a 2-year fixed rate ISA and how does it work?
A 2-year fixed rate ISA is a tax-free savings account where your money is locked for two years at a set interest rate, typically paid annually or at maturity. The core benefit is certainty: your funds grow at the agreed AER without exposure to rate changes. This differs from stocks and shares ISAs, which carry investment risk but potential for higher returns, or easy-access cash ISAs that allow withdrawals but lower fixed yields.
Interest is calculated daily but credited yearly, with AER accounting for compounding to show the true return. For example, on a £10,000 deposit at 4.16% AER, you’d earn about £852 tax-free over two years. Eligibility requires UK residency and being 18+, with transfers from existing ISAs possible to maximise your allowance.
Key benefits for medium-term growth
- Guaranteed returns lock in current high rates before potential cuts.
- Tax-free status shields interest from personal savings allowance limits.
- Medium-term commitment suits goals like home deposits or retirement boosts.
Tip: Maximise your ISA allowance
Combine a 2-year fixed rate ISA with other ISA types to use your full £20,000 limit. As Martin Lewis from MoneySavingExpert advises, don’t leave cash in low-rate accounts—transferring could add hundreds in interest. Always check penalties before committing.
