In the specific scenario where an insurer has accepted a claim but disputes the valuation of the monthly benefit payment, the FOS would assess the complaint based on what is, in the opinion of the Ombudsman, “fair and reasonable” in all the circumstances of the case (DISP 3.6.1R, DISP 3.6.2G and, in relation to the FOS’ compulsory jurisdiction, FSMA 2000, s 228(2)). If the complainant challenges the valuation, the FOS would consider all the submitted evidence (which would presumably include any contracts with the insurer) and relevant industry practices
