The best cash Isas – March 2023

Easy access and notice ISA rates are now at their highest since 2009. Here are the best cash ISAs on the market today.

Easy access and notice ISA rates are now at their highest since 2009 as providers look to bring in new customers ahead of the new tax year.

The average easy-access ISA rate stands at 1.96%, according to Moneyfactscompare, and some easy access accounts are offering as much as 3.2%.

The Bank of England’s latest interest rise means providers are not holding back when it comes to increasing these rates - which is good news for savers looking to park their cash into the tax free wrapper. 

While MW readers know too well a stocks and shares ISA may serve you well for long-term savings, for anyone looking to hold on to cash for the short-term or held back by the market volatility, a cash ISA may make good sense. 

You can also park your cash within your investment ISA, but MoneyWeek recently revealed that interest rates on these platforms can be dismal, so grabbing a higher rate on cash ISA can be a good idea if you have yet to make use of this year’s £20,000 allowance.

To help you, we have rounded up the best cash ISA rates on the market today.

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.
