Is your cash working as hard as it could be?

42% of UK adults hold a Cash ISA. Right now, banks are competing hard for savers' money.

Fixed-rate Cash ISAs are currently offering some of the most competitive tax-free savings rates available. We track rates weekly across UK providers – from 1-year to 5-year terms – so you always know where your money works hardest.

Easy access and fixed-rate ISAs can top 4.7%. But which is right for you?

Easy access or fixed? The plain-English version.

🔓 Easy access — Withdraw anytime, no penalties. Rates move with the Bank of England. Good for emergency funds or money you might need.

🔒 Fixed-rate — Lock away for 1–5 years for a guaranteed (usually higher) rate. Early withdrawal typically penalised.

↩️ Flexible ISA — Withdraw and replace in the same tax year without using up your allowance. Not available on all ISAs.
