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.
Corinthian Service Company Limited (FRN 1046642) is an AR of ACRISURE RE CORPORATE ADVISORY & SOLUTIONS LIMITED (FRN 964339). When you use Corinthian Service Company's services, the FCA authorisation sits with the principal firm.
Example: if you take financial advice from Corinthian Service Company, 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.
