Use the FCA’s Financial Services Register to search the firm’s name or Firm Reference Number, then check that its details and permissions cover mortgage advice or arranging. Make sure the contact details match the firm you are dealing with, as scammers sometimes copy authorised businesses’ details. If the firm is an appointed representative, check the principal firm listed and ask who is responsible for its activities. PoundWise is an independent information site, so contact the FCA or a regulated mortgage professional if you are unsure whether a firm is authorised.
