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.
  • G&HZ Limited t/s Sloan Block Management (FRN 1062029) introduces customers to GAD Corporation Ltd (FRN 1007422). Any regulated advice or arranging is done by the principal, not G&HZ Limited t/s Sloan Block Management.
  • Example: if G&HZ Limited t/s Sloan Block Management refers you to a financial adviser, the advice should come from the principal firm, not from G&HZ Limited t/s Sloan Block Management 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.

This company holds another FCA record

A company can hold several FCA records, covering different parts of its business, and each one carries its own permissions and protection. The reference number you were given decides which record applies to you.

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.
