Top 54 Cash ISA Providers Comparison

A Cash ISA works in much the same way as an ordinary savings account, except you do not pay tax on the interest you earn. This makes them an attractive option for anyone who normally pays tax on their savings. There are two main types of Cash ISA: Variable and Fixed.

What is a Cash ISA?

A Cash ISA works in much the same way as an ordinary savings account, except you do not pay tax on the interest you earn. This makes them an attractive option for anyone who normally pays tax on their savings.

There are two main types of Cash ISA: Variable and Fixed. Variable Cash ISAs pay variable rates of interest, which means that the interest you earn could go up or down. Variable Rate ISAs are flexible, which means that you can withdraw money from an ISA anytime and replace it later, without the replacement counting further towards your ISA allowance.

Fixed Rate ISAs, on the other hand, pay a fixed rate of interest for a set term, rather like a savings bond. However your money is locked away until maturity (when the fixed period comes to an end) and you cannot access it unless you are willing to pay a fee for early withdrawal. Fixed interest ISAs usually have better rates of interest than flexible ones for this reason.

How much money can I put into a Cash ISA?

You can save up to a maximum of £20,000 into a Cash ISA in the current tax year. This money will earn you tax-free interest on your savings. This has remained unchanged from the previous year. This £20,000 limit applies to each adult, so if you are married or have a civil partner you each have a £20,000 limit each year.

How many Cash ISAs can I have?

You can have multiple Cash ISAs, but you can open only one Cash ISA in each tax year. You are allowed to divide your annual allowance according to any proportion you like, which means you can split your yearly ISA allowance of £20,000 across the different types of ISA that you hold, should you wish to.
