Log into your online banking and select 'Alerts' on the top left hand side. This will take you to your Alerts home page where you need to select 'Manage my Alerts.' This will take you to the page shown where your current settings are displayed. To change these select 'Amend these alerts settings.'
Use the drop down bar on the right hand side of each alert to select off, email or text. For balance alerts enter the value to wish to be alerted at. Select next once you are happy with the alerts set up.
This screen asks you to review all of the alerts and select confirm if you are happy. If you do want to make amendments select back.
The final step is the confirmation screen telling you all your alerts are active. You will receive new alerts from this point. You can review and change your alerts anytime online.
