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.
  • Onex Partners Advisor UK LLP (FRN 731740) is an AR of Carne International Financial Services (UK) Limited (FRN 823316). When you use Onex Partners Advisor UK's services, the FCA authorisation sits with the principal firm.
  • Example: if you take financial advice from Onex Partners Advisor 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.

Website, phone number and address

Compare these against whatever you were given. Scammers clone real firm names and reference numbers but use their own phone number and website, so a detail that does not match the register is the clearest warning sign there is.
