Simply sign into Online Banking, tell us how much you need and what you’re planning to use the overdraft for. 

3. Receive a response

Once you submit your application:

  • If you’re a sole trader or sole director company, it usually takes a few minutes to receive a decision. If your application is approved, you’ll receive an email to sign your overdraft contract.
  • If you’re applying as a partnership, trust or multi-director company, one of our specialist bankers will review your application and be in touch to discuss next steps.

Your overdraft will appear in your Online Banking ready for you to use. It typically takes one business day of you signing and returning the contract for the funds to appear.
