The Nuts and Bolts

We’re up front with our customers about everything. We’ve created this handy summary of our Instant Access Cash ISA's key features so you can see the important information from the get-go.

Interest rate Save from Annual tax free allowance Interest paid


0.20% AER*


£1 £20,000 for 2022/23 Annually

*AER stands for annual equivalent rate. It shows how much the interest rate would be if the interest was worked out once a year. You can use it to compare different financial products.


You can apply to open an account if:

  • You’re aged 16 or over
  • You have a National Insurance number
  • You’re resident in the UK. You’ll also need to provide proof of your identity and address. If you’re not a UK, EU, EEA or Swiss national you’ll need a valid visa/residence permit. Here’s a list of what you need.

Annual tax free allowance and interest

You can only subscribe to one cash ISA in a tax year. The amount you can save into an ISA in the 2022/23 tax year is £20,000. Interest on your ISA will be paid annually on or around 5th April.

Withdrawals and notice periods

Unlimited access to your money. No notice needed. Funds withdrawn can be replaced in the same tax year.

Transfers in

You can transfer money from an ISA with another bank or building society to our Instant Access Cash ISA. And you’ll earn interest on this money before it even arrives in your account – we start paying interest from the date we receive your transfer request.

This doesn’t apply to transfers from accounts where you have to give notice to take money out. It also doesn’t apply when you’re transferring money from a stocks and shares ISA.

If you want to make a transfer in, you’ll need to do it within 30 days of opening your Instant Access Cash ISA.

You can transfer as many previous years’ funds as you like.

Charges for banking services

We’ll charge you for issuing a banker’s cheque. Each cheque costs £15.

What does tax-free interest mean?

We give you interest on the money you put away in your cash ISA. You don’t have to pay UK income tax or capital gains tax on this interest. It doesn’t count towards your Personal Savings Allowance and you don’t need to put it on your tax return.

Since 6 April 2016, you can earn up to £1,000 a year on your savings tax-free if you pay the basic rate of tax and up to £500 a year if you pay the higher rate of tax. This is called your Personal Savings Allowance. Interest on your savings is now paid without tax being taken off. The interest from ISAs doesn’t count towards your Personal Savings Allowance.

Can I take money out of an Instant Access Cash ISA?

Yes. You can take money out whenever you like. If you can afford to put some money away for longer, you might be interested in our Fixed Rate Cash ISA

Can I transfer a stocks and shares ISA to a Fixed Rate Cash ISA?

Yes. You just need to fill in a stocks and shares ISA transfer form in store.

Can I replace money I’ve taken out of my Instant Access Cash ISA in the same year?

Yes – but however much you take out, your total payments in can’t go over the ISA allowance for the tax year. This is £20,000 for 2022/23. 

Where can I find the rate for my Metro Bank account that’s now closed to new savers?

You can find the rates for any account that is not listed on the current rates page set out in Rates for Closed Products.
