A one-year fixed bond at 4.35% guarantees you £435 on every £10,000 deposited, regardless of what the BoE does next. That's not exciting. But it's certain — and in a cutting cycle, certainty has value.
Consider the alternative. If you keep £10,000 in easy-access at 4.2% today but that rate falls to 3.5% by September (entirely plausible after two more cuts), your blended return for the year might be closer to 3.8%. You've given up £55 per £10,000 for the privilege of having access to money you weren't planning to spend.
The FSCS protection limit now covers £120,000 per person, per institution — up from £85,000 since December 2025. You can spread across multiple providers and still lock in competitive rates with full protection.
For those with ISA allowance remaining, the same logic applies. The best Cash ISA rates are tracking fixed bond rates down. If you're going to use your £20,000 ISA allowance before 5 April, doing it now at current rates beats doing it in April at whatever's left.

For higher-rate taxpayers, the Personal Savings Allowance drops to just £500, making the case for a cash ISA even stronger. Inside an ISA wrapper, your fixed-rate returns are entirely tax-free — a meaningful advantage when every basis point counts in a falling-rate environment.
