If you're already using Online Banking to manage your credit card or another banking product, you don't need to register again for your current account. However, you won't be able to access your current account straight away.
Once your current account is open, you can add it to your Online Banking Overview using your credit card login details.
Log in to Online Banking and enter your current account details in the Add my account section on the Online Banking Overview and follow the instructions.
You'll now be able to access and manage both your current account and your credit card using your credit card login details.
