Best Cash ISAs

A Cash ISA (Individual Savings Account) is similar to a regular savings account, but you earn tax-free interest on your savings.

As long as you don't exceed the annual contribution limit, you can technically have as many Cash ISAs as you like. You can have Cash ISAs with different providers, although some will only let you have one Cash ISA with them.

As of the 2025/26 tax year, the annual ISA allowance is £20,000. This is the maximum amount you can save in any ISAs you have, and this isn't restricted to just one ISA. You can save up to £20,000 in Cash ISAs, Stocks and Shares ISAs, and one Lifetime ISA in a single tax year.
