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.
  • AMENTUM CLEAN ENERGY LIMITED (FRN 1034694) introduces customers to Cycle Solutions (Cycle to Work) Limited (FRN 722968). Any regulated advice or arranging is done by the principal, not AMENTUM CLEAN ENERGY.
  • Example: if AMENTUM CLEAN ENERGY refers you to a financial adviser, the advice should come from the principal firm, not from AMENTUM CLEAN ENERGY 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.
