ADR Chambers Banking Ombuds Office (ADRBO) reviews decisions of participating banks when the bank's customers are not satisfied with the outcome of the bank's internal Ombudsman process. An independent ADR Chambers Investigator can advise customers about whether they have been treated fairly. If a complaint requires a full investigation, an investigation will be conducted and the Investigator may make non-binding recommendations.

ADR Chambers is a private company that operates independently from the participating banks. The ADR Chambers Ombuds service is free of charge to those making the complaint.
