However some of our accounts (i.e. children's savings accounts) use different eligibility criteria.

Please check individual products for specific eligibility.

What you need to apply

  • Your addresses for the last 3 years.
  • If applying for a cash ISA, your National Insurance (NI) number.

How long applications will take

If you have all your information to hand, the application will take you roughly 10 minutes.

It will take us around 5 working days to let you know whether or not your application was successful.

Remember you can subscribe to a Co-operative Bank / Britannia Cash ISA as long as you have not subscribed to another cash ISA with another provider in the current tax year.

Savings terms explained

AER stands for Annual Equivalent Rate and shows what the interest rate would be if it were paid and added to your account each year.

Fixed interest means the rate stays the same until the account matures.

Gross is the rate of interest payable before any tax is taken off.

Tax-free means you will not pay any tax on your interest.

Tax year runs from 6 April to 5 April.

Variable interest means that it could go up or down.

Business day is usually Monday to Friday excluding bank holidays.

Any reference to tax is based on our understanding of current tax regulations which may change in the future and depends on the customer's individual financial circumstances.

The Co-operative Bank reserves the right to decline to accept any application and/or deposit.
