The best cash Isas – December 2022

Cash Isas may be making a comeback as rates creep up – here are the best cash Isas on the market today.

If you’re hoping to take advantage of higher interest rates coming back to the cash savings market, then you may be looking for one of the best cash ISAs to grow your money.

The best cash ISAs on the market today now offer rates of up to 4.65%, though you’ll need to be prepared to lock your money away for two years. It may also be possible to earn an even higher rate if you’re prepared to lock your money away for longer. 

While it might be tempting to lock in these high rates now, it looks as if the Bank of England will be raising interest rates further over the coming months. So, a cash ISA with unlimited withdrawals might be a good option – allowing you to switch to a higher rate if one comes along in the future.

Cash ISAs operate in the same way as an ordinary savings account, but you don’t get charged tax on any interest you earn. You can save up to £20,000 a year in one type of account or split that allowance across different types of ISA accounts – such as a stocks and shares ISA. A stocks and shares ISA may be a good option if you want to save for a longer period – five years or more. 

Some ISA accounts are also what’s known as “flexible ISAs”. This means you can withdraw money from your account and put it back in the same tax year without it affecting your annual allowance.

Below are the best cash ISA accounts available for easy access, and for 12- and 24-month fixed-rate accounts.

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.
