Summary Box for Co-operative Bank Fixed Rate Cash ISA
Account name
The Co-operative Bank Fixed Rate Cash ISA
What is the interest rate?
Interest paid annually
3.93% tax-free / AER for a 1 year Fixed Rate Cash ISA
3.75% tax-free / AER for a 2 year Fixed Rate Cash ISA
Interest is calculated daily and is paid annually on the anniversary of the start of the fixed term. If this date doesn’t fall on a Business Day, it will be paid on the next available Business Day.
Your fixed term will start from the date we receive and accept your initial deposit, or the date we receive the transfer value for your existing cash ISA — whichever is earlier.
Interest can either be paid into this account or another account of your choice, with us or another provider.
The fixed rate you receive will be the rate on offer for the term you select on the date your application is received.
Can The Co-operative Bank change the interest rate?
No, the interest rate is fixed. It won’t change until the account matures at the end of your term.
What would the estimated balance be after 12 months based on a £5,000 deposit?
Balance at end of fixed term
£5,196.50 would be the balance after a 1 year fixed term
£5,382.03 would be the balance after a 2 year fixed term
This calculation is for illustrative purposes and assumes:
- You haven’t made any additional deposits or withdrawals
- You’ve chosen to add your interest to the account.
How do I open and manage my account?
Open an account
To open an account you must be a UK resident aged 18 or over. Please note: this account can only be opened as a sole account.
You can open an account:
- Online
- In branch
- By post.
How much can I deposit?
The minimum deposit is £5,000, but if you’re transferring in previous tax years’ ISA allowances only – then the minimum deposit is just £1.
The maximum deposit if you are using your annual ISA allowance is £20,000 per tax year. But if you’re transferring in ISAs from previous tax years’ ISA allowances, the maximum balance is £1,000,000.
The maximum account balance is £1,000,000.
You’ve got 30 days from when we open your account to pay in the minimum deposit. You can do this in one lump sum or through multiple payments up to the maximum amounts above. If after 30 days you haven’t met the minimum deposit, we’ll close the account and return any funds to you. No further deposits are allowed after 30 days from account opening.
How do I pay into this account?
If you’re using your annual ISA allowance
You can pay your initial deposit(s) into this account by cash, cheque or transfer from another account held with us or another provider. You can also pay cheques in at the Post Office®.
If you’re transferring an existing cash ISA you have (with us or elsewhere) to this account
You can do this by providing us with a completed Cash ISA Transfer Authority Form. You’ll receive the form with your welcome letter so just complete it, return it to us and we’ll arrange the transfer on your behalf.
You must not withdraw the funds yourself to transfer to this account as they will lose their tax-free status.
How do I manage this account and get in contact?
You can contact us, and manage this account:
- Online
- Over the phone
- In branch
- By post.
Can I withdraw money?
Yes — however, if you withdraw before your maturity date, you’ll be charged the value of 180 days’ interest on the amount you withdraw (using the account’s interest rate). This charge will be taken from interest you’ve earned, but hasn’t been paid. But if you haven’t earned enough interest to cover this charge, some of it will come out of your original deposit(s).
Any money that you withdraw from your ISA will lose its tax-free status, and, if repaid back into an ISA, it will count towards your current tax year's ISA allowance.
So, for example, if you have deposited £10,000 and then withdraw £1,000, you will only be able to deposit a further £10,000 in that tax year.
You can withdraw money:
- In branch
- By telephone
- By requesting a bankers cheque — there is a charge for this.
At the end of the fixed term, your account matures and your money will be put into a variable rate instant access cash ISA — unless you provide us with other maturity instructions.
We’ll send you a letter before your maturity, to remind you of your maturity date and to let you know what options are available to you (such as re-investing or withdrawing).
On maturity, you can access your money in branch, over the phone, by post, through online banking and through our mobile app, if registered.
Additional information
This is a limited issue product and may be withdrawn without notice at any time.
If you are or have previously been made bankrupt, you are eligible to apply.
Interest earned from this account will not count towards any of your available Personal Savings Allowance.
All interest earned from your ISA will be tax-free.
You cannot pay into a cash ISA with us if you have already paid in the full annual ISA allowance in this tax year.
For more information about ISAs in general, please read our ISA Allowances and information guide.
Transferring an existing cash ISA
If you like, you can transfer money from an existing cash ISA into a Co-operative Bank Fixed Rate Cash ISA. Your existing ISA might be with us, or another provider.
If your existing cash ISA is with another provider, they may have restrictions relating to ISA transfers — we recommend checking this before requesting a transfer to us.
You must not withdraw the money and transfer it to us yourself, as it will lose its tax-free status.
I want to open and transfer money to a new Co-operative Bank Fixed Rate Cash ISA
If you wish to transfer an existing cash ISA held with us or another provider to a new Fixed Rate Cash ISA, you’ll need to:
- Apply for a new Fixed Rate Cash ISA
- Complete the Co-operative Bank Cash ISA Transfer Authority form, which’ll arrive with your welcome letter or download it
- Return the completed form to us.
Apply in branch
If you’d rather not apply online, you also have the option to apply in one of our branches.
