About us
An independent voice when claims get complicated.
C. Lewis & Company is an independent forensic accounting firm. We provide advice on claims and disputes in the insurance industry and beyond, working with insurers, policyholders, lawyers and risk managers who need a rigorous, defensible view of the numbers.
Our clients are world leaders in their fields, and we have built a reputation for providing real solutions to complex situations. We are routinely instructed on claims and disputes, from small sole-trader losses to claims well in excess of £1 billion, and we provide litigation support and expert witness services outside of the insurance industry too.
