The Controlled Functions of the Financial Conduct Authority (FCA) are simplifying code names given to various functions within the financial services and relating to the carrying on of regulated activities by a firm. These are specified, under section 59 of the Financial Services and Markets Act which still stands as the reference after the FSA split into the FCA and the PRA. The FCA is solely responsible for all applications for approval for FCA Designated Controlled Functions for all FCA solo regulated firms.
