    Find a branch


    When you close your account, we will provide you with up to 5 years of payment transaction history in an electronic format. If you have Online Banking, it’s already available by downloading your previous statements from your document store.


    If you don’t have Online Banking, an electronic copy of your payment transaction history is still available, but you’ll need to request Online Banking log on details to be able to view and download this information. Visit the Online Banking page to find out how to sign up.


    If you don’t want your payment transaction history right now you can still ask for it for up to 5 years after closing your account, but we will only provide your payment transaction history for that period when your account was open in the 5 years before your request. For example – if you request it:

    • three years after you closed your account, we’ll provide two years of payment transaction history
    • two years after you closed your account, we’ll provide three years of payment transaction history etc.


    If you would like your payment transaction history in another format, you can request this by calling us on 0800 9 123 123 or visiting your local branch.


    We’re not required to provide payment transaction history at account closure if your current account has been closed due to:

    • fraud or other unlawful activity;
    • the death of an account holder; or
    • the account has not been used for five or more years (which means there is no payment transaction history).
  • Your bond maturity date can be found on the bond certificate that was issued to you when you opened the account.

  • The easiest way to change your address and contact details (including your telephone number and email address) is to do it via Online Banking. It will be changed instantly.

    If you have a joint account you can only change your own name and/or address within Online Banking. If both names and/or addresses need to be changed, both account holders must log on to their own Online Banking and change their own details.

    You can also change it by telephone or in branch.

      Log on and update your details instantly from within the "My Details & Settings" tab.

      • Choose 'Change personal details' from the left hand menu and then click 'Change address'.

      • Enter your new details (including postcode) and follow the onscreen instructions.

      • Please note: You will need to enter a One Time Passcode (OTP) to complete this change, so make sure you have your mobile phone to hand.
