Check if you can borrow what you need before you apply, with a decision in principle. It won’t affect your credit rating. 

Log on to Online or Mobile Banking, choose your mortgage and go to ‘Manage my mortgage’. If agreed, you can continue your application. 

Get online

You can get instant access to Mobile and Online Banking. You need your account details, and the mobile phone that's currently registered for One Time Passcodes (OTPs).

Mobile and Online Banking log on details are the same.

Alternatively, you can get in touch with our mortgage team.

Do you have a Flexible Offset mortgage?

With a Flexible Offset mortgage you have an agreed additional borrowing limit, at the same rate as your mortgage. You can access your additional borrowing through Online Banking and repay on a repayment or interest only basis. If you need to increase your additional borrowing limit, you can ask for a credit limit review
