How do I make my sole account into a joint account?

You can do so by completing our online process. Please follow our guidance here (opens in a new window) to ensure we have all of the information we require to process your account change.

If your current account holds insurance benefits you’ll need to visit our branch and will not be able to request online. Not sure which account you have? See guidance (opens in a new window).

Please ensure both applicants take in one form of photo ID and one proof of address when visiting the branch.
