What does this mean?
  • An appointed representative (AR) can carry out regulated financial services, but is not directly authorised by the FCA. A principal firm holds the authorisation and is legally responsible for the AR's conduct.
  • Costco Online UK Limited (FRN 1056750) is an AR of Costco Wholesale UK Limited (FRN 735258). When you use Costco Online UK's services, the FCA authorisation sits with the principal firm.
  • Example: if you take financial advice from Costco Online UK, complaints and compensation usually follow the same rules as dealing with the principal, but this depends on the product and your circumstances.
  • Before you proceed, confirm contact details match the official FCA register for both firms. Scammers sometimes clone legitimate AR names and FRNs but use fake phone numbers and websites.
