Introducer appointed representative

This firm can only introduce you to its principal, and cannot give financial advice, recommend products, or arrange deals alone.

What does this mean?
  • An introducer appointed representative can only pass your details to its principal firm. It cannot recommend products, give financial advice, or arrange deals on its own.
  • UNITED KINGDOM NATIONAL NUCLEAR LABORATORY LIMITED (FRN 972329) introduces customers to Cycle Solutions (Cycle to Work) Limited (FRN 722968). Any regulated advice or arranging is done by the principal, not UNITED KINGDOM NATIONAL NUCLEAR LABORATORY.
  • Example: if UNITED KINGDOM NATIONAL NUCLEAR LABORATORY refers you to a financial adviser, the advice should come from the principal firm, not from UNITED KINGDOM NATIONAL NUCLEAR LABORATORY itself.
  • 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.
