If we can resolve your complaint within 3 business days following the day we received it, we’ll send you confirmation of this and we’ll also let you know about the Financial Ombudsman Service (FOS) at this time.
For more complex issues, we may need more time to investigate your concerns. If this is the case:

Our final response
Once we've completed a thorough investigation, we'll give you a final response. This will outline the details of our investigation, how we reached our decision and what we’re going to do to put things right. It may also provide information about the Financial Ombudsman Service or the Business Banking Resolution Service.
We aim to resolve all complaints as quickly as possible and specific timescales apply to certain types of complaints:
Complaints relating to payments in or out of your account:
These include complaints about making or receiving payments on your Current Account, Credit Card or Instant Access Savings account.
- We’ll send you our final response as soon as we’ve completed our investigation. We have 15 days to resolve these complaints.
- If there are exceptional circumstances we may take longer than 15 days to investigate your complaint, we’ll however resolve all payment complaints within 35 days. We’ll write to you to let you know if we need longer than 15 days, we’ll also send you details about how to refer the matter the Financial Ombudsman if you would prefer not to wait for us to finish investigating your complaint.
All other complaints:
Although we have 56 days to resolve your complaint, we’ll send you our final response as soon as we’ve completed our investigation.
We’ll also keep you informed in writing along the way so you’ll know when to expect to hear from us.
If we haven’t been able to finalise our investigation by 56 days we’ll send you a letter letting you know and what steps you can take. These will include letting you know you can go to the Financial Ombudsman if you’d prefer not to wait until we’ve finalised our investigation.
