  • Be a UK resident (for tax purposes).
  • Be aged 16 or over.
  • This account can only be opened as a sole account.

How do I apply for this account?

  • Through online banking existing customers can easily apply through the 'Products' section within online banking.

The minimum opening balance is £1.

The maximum balance is £1,000,000.

  • You've got 30 days from when we open your account to pay in the minimum balance of £1. If after 30 days you haven't met the minimum balance, we may close the account immediately and return any funds to you.

How do I make deposits into this account?

If you're using your annual ISA allowance for the current tax year - you can pay money in by:

  • Electronic transfers from another account held with us or another provider (such as by using their app or setting up a standing order).
  • Cash or Cheques
  • Visiting any Post Office® in the UK where you can pay in cheques.
  • The maximum you can pay into the Cash ISA in the 2018/2019 tax year is £20,000.

    If you're transferring your cash ISA to us - you can do this by providing us with a completed ISA transfer authority form. You'll receive the form in your welcome pack so just complete it, return it to us and we'll arrange the transfer on your behalf.

How do I contact you to discuss this account?

By telephone or in branch.

Can I withdraw money?


Yes - whenever you want as this account has no restrictions on the number of withdrawals. However, as this cash ISA is not a flexible cash ISA, any withdrawn money that you want to replace will count towards your ISA subscriptions for the current tax year, and you are only allowed to deposit up to the maximum ISA limit in a tax year.

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 make withdrawals through the following ways:

  • Online and Mobile Banking through electronic transfers to other accounts with us or another provider.
  • Telephone Banking through electronic transfers to other accounts with us or another provider.
  • Branch withdraw cash over the counter and/or make electronic transfers to other accounts with us or another provider.
  • You can also request a Banker's cheque withdrawal over the phone or in branch, however there is a charge for this.

Additional information


If you are or have been previously made bankrupt, you are eligible to apply.
