The rates on many of the best cash ISAs have disappeared alongside savings accounts after the Bank of England cut interest rates twice in 2024. So you will need to act fast to get the top rates before they get pulled.
The good news is that some cash ISAs are still returning inflation-busting rates above 4.75%, so it's worth checking if you're making full use of your £20,000 ISA allowance.
A stocks and shares ISA is a good option for long-term savings, but a cash ISA may make good sense for short-term savings.

What you need to know about the best cash ISAs
When choosing a cash ISA, there are two main factors to look out for: how long you are comfortable locking your cash up for and the interest rate.
- Easy access ISA accounts allow you to withdraw funds without incurring a penalty.
- Fixed-rate cash ISAs offer a fixed rate of return – usually higher the longer you are prepared to lock your money away. But note: if you withdraw money before the end of the term, then you are likely to be penalised, usually with a reduction in the rate of interest.
Generally speaking, the longer you leave the money untouched, the more interest you can earn. Many ISAs are classed as ‘flexible’, meaning you can replace any funds you withdraw in the same tax year without affecting your annual ISA allowance – which is currently £20,000.
