Appointed representative
This firm does not hold FCA authorisation of its own, and acts under a principal firm, which is legally responsible for its regulated business.
Responsible principal firm
NEWLINE UNDERWRITING MANAGEMENT LIMITED Reference number: 204958 View firm →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.
- Newline Underwriting Limited (FRN 402981) is an AR of NEWLINE UNDERWRITING MANAGEMENT LIMITED (FRN 204958). When you use Newline Underwriting's services, the FCA authorisation sits with the principal firm.
- Example: if you take financial advice from Newline Underwriting, 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.
