Firms are reminded that new FCA complaints handling rules in the Dispute Resolution: Complaints sourcebook (DISP) come into force at the end of June which relate to:  (i) extending the "next business day rule" (under which firms are permitted to handle complaints less formally, without sending a final response letter) to the close of three business days after the date of receipt: (ii) reporting all complaints, including those handled by the close of three business days after the firm receives them; (iii) raising consumer awareness of the FOS by sending a "summary resolution communication" following the resolution of complaints handled by the close of the third business day after receipt; and (iv) introducing an improved complaints return, requiring firms to send data on the number of complaints they receive to the FCA, twice a year.
