Complaints Handling

When we receive a complaint from you it is our policy to respond to you in writing to confirm that the complaint has been received and is being handled.

Where possible, our aim is to resolve your complaint within 3 business days. If this can be done, we will send you a summary resolution document to confirm how the complaint has been resolved and subsequently closed.

If this is not possible and further investigation is required, we will confirm this to you in writing and provide you with a point of contact at our Bank. We will keep in contact with you to update you on progress while we investigate and will send you a final response within eight weeks, at latest.

If you are not satisfied with our final response you have the right to refer your complaint to the Financial Ombudsman Service (FOS). This is an independent public body who can review your complaint on an impartial basis and make a final decision on the matter.

If you wish to refer to the FOS, you will need to do so within six months of receiving the final response from us.
