In order to assist us in resolving any complaint you may have, please provide us with the following information:

  • Your name and address
  • Your account number
  • A description of your complaint
  • Your contact details (telephone, mobile, email) and a convenient time to call you


 How we will deal with your complaint           

Step 1:

Upon receipt of your complaint, the bank will issue a ‘Letter of Acknowledgement’ within 1 business day.

Step 2:

If we are able to resolve your complaint within the 3 business days we will send you a ‘Summary Resolution Communication’ (subsequent to the resolving of your complaint) informing you of how your complaint was resolved. If we are unable to resolve your complaint by this time step 3 will apply.

Step 3:

Within 4 weeks, we will write to you and inform you of our “final response” detailing our explanations and any offer of redress. If we are unable to do that, we will let you know at what stage our investigations are at.

Step 4:

Within a further 4 weeks (a total of 8 weeks since acknowledging your complaint), we will send you our “final response” detailing our explanations and any offer of redress. If we are unable to do that, we will let you know at what stage our investigations are at.

If at this stage we have not sent you our “final response” or you are dissatisfied with our “final response” and you are an eligible customer, you can refer your complaint to the Financial Ombudsman Service for an independent review but within 6 months of the date of our “final response”.
