Update your contact details

Your contact details are your address, phone number, email and marketing preferences. How you change them depends on the type of product you have, and whether you have access to the Internet Bank. If you don’t have online banking, you can download our change of address form and post it to us, or drop it into your local branch. Or you can call Customer Services and speak to an adviser.
