A guide to 1 year fixed rate ISAs

At a glance

  • Earn a higher rate of interest than on a notice or easy access cash ISA
  • Make sure you can commit your money for a year
  • You can only usually make one deposit and/or transfer to the fixed rate ISA

Why should I choose a one-year fixed rate ISA?

One-year fixed rate ISAs are an excellent way to get a better rate of interest than might be possible with a notice or easy access account. Of course, if you do decide to invest in a one-year fixed rate ISA it’s important to be sure that you won’t need to access those savings for a whole year. While early access might be possible you’ll penalised with a hefty, if not total loss of interest.

How does a 1 Year ISA work?

In the 2019-20 tax year (a tax year runs from 6 April to the following 5 April), you can deposit up to £20,000 into a cash ISA. You are only allowed to open one new cash ISA per tax year, so if you opt for a 1-year fixed rate ISA, you will not be able to open another cash ISA until the next tax year. The only exception to this is if a provider allows you to ‘share’ your ISA allowance across their range of cash ISAs.

You may only be able to make a single deposit and/or transfer in to your 1-year ISA when you open the account. You might be permitted to make further deposits into the ISA, but this is only while the product remains on general sale. However, as soon as the fixed rate ISA is withdrawn from sale to new customers, you won’t be able to put any further money into it.

Although you will be able to transfer money out of your ISA, there will usually be a hefty interest penalty to pay. If you think you’ll need access to your money within the 1-year term, look instead at an ISA that will allow easy access, or penalty-free access after a notice period has been served.
