Compare Cash ISAsWhat to compare in 2026

Cash ISAs let eligible savers earn tax-free interest within ISA rules, but the right product depends on access, fixed terms, transfer rules, minimum deposits, withdrawal penalties and whether the rate is variable or fixed.

Quick answer

Atom, Kroo, TSB, Metro Bank, Virgin Money, Co-operative Bank, First Direct, Barclays, Lloyds, HSBC, Nationwide and other reviewed banks are relevant Cash ISA comparison points. Do not compare Cash ISAs by headline AER alone; check access rules, transfer rules and penalties too.
