What are fixed rate cash ISAs?
Fixed rate cash ISAs offer a guaranteed interest rate for a set period, typically 1-5 years, making them ideal for savers seeking stability amid fluctuating best cash isa fixed rates. These tax-free accounts lock your money away, providing higher returns than variable options in the current UK market, where average one-year fixed rates stand at 3.89% as of October 2025 (Moneyfactscompare.co.uk, accessed 2025-10-25). Unlike easy access ISAs, they prioritise security over flexibility, protecting against rate drops.
How they work
You deposit up to £20,000 annually into a fixed rate cash ISA, earning interest at a predetermined AER (annual equivalent rate), which shows the true yearly return including compounding. At maturity, your funds plus interest become accessible, though early withdrawals often incur penalties equivalent to 90-180 days’ interest. This structure suits those planning medium-term goals, like saving for a house deposit.
Benefits versus easy access ISAs
Fixed rate options deliver predictable earnings, currently topping out at 4.28% for one year from providers like Vida Savings (Moneysavingexpert.com, accessed 2025-10-25), compared to variable easy access rates around 4.52% but with no guarantees. While easy access suits emergency funds, fixed ISAs shield against Bank of England base rate cuts, offering peace of mind for risk-averse UK savers.
Eligibility and allowance
UK residents aged 18+ can open a cash ISA, with the 2025/26 tax year allowance fixed at £20,000 from 6 April 2025 to 5 April 2026 (Moneysavingexpert.com, accessed 2025-10-25). Transfers from existing ISAs don’t count towards this limit, allowing you to consolidate into better fixed cash isa rates without losing tax benefits. All eligible accounts are protected up to £85,000 by the FSCS.
