New account numbers for a small group of customers

Attention: open in a new window. Print

As a part of our system preparation we have identified a small group of customers who will need to have one of their account numbers replaced with a new one before we move to our new core banking system.

We’ve placed these customers into two groups ‘no-impact’ and ‘some impact’.

Click here for further details on these customers and the approach.

Please note: there are teams managing this step by step in the back office, you will only be required to answer enquiries and open a new savings account if the customer requests it immediately (before our team have a chance to process this).

Letters will start to be received by customers from mid next week, to assist, please find the below FAQs. If you have any questions or require any new FAQs please send them through to
