Key Facts

  • Best easy-access cash ISA rates reached around 4.75% in May 2026
  • Savings up to £85,000 per bank are protected by the FSCS
  • Some headline rates include a temporary bonus that later drops

What a good rate looks like

In May 2026 the best easy-access cash ISAs paid up to roughly 4.75% AER, with one-year fixed ISAs around 4.66%. Rates change constantly, so a figure that's competitive one month may slip the next.

Often the best rates come from less familiar banks and building societies rather than the big high-street names, because they're working harder to attract deposits. As long as they're FSCS-protected, your money is just as safe up to £85,000.

Traps to watch for

Some headline rates include a temporary bonus — for example an extra 1-2% for the first 12 months — after which the rate drops sharply. Check whether a rate is bonus-boosted and diarise when it ends so you can switch.

Also check withdrawal rules. 'Easy access' accounts sometimes limit the number of penalty-free withdrawals, and fixed ISAs lock your money away. Use comparison sites like Moneyfacts or MoneySavingExpert's best-buy tables to see the live market.

FAQ

Frequently Asked Questions

Is a cash ISA worth it if I don't pay tax on savings anyway? +
Maybe not right now, but it can future-proof your savings. The personal savings allowance lets basic-rate taxpayers earn £1,000 of interest tax-free outside an ISA, but if your savings or rates grow, or you become a higher-rate taxpayer, an ISA shelters everything. Compare the actual rates before deciding.
How often should I switch my cash ISA? +
Check your rate at least once a year, and especially when any introductory bonus ends. Loyalty rarely pays in savings — providers often quietly drop rates on older accounts. If a better deal is available, transfer using the official ISA transfer process to keep your tax-free status.
Are cash ISAs safe? +
Yes, as long as the provider is covered by the Financial Services Compensation Scheme, which protects up to £85,000 per person per banking group. Your balance won't fall in a cash ISA — you simply earn interest — so the main risk is just earning less than inflation if your rate is low.
