Excess Liability

Hamilton’s Excess Liability product, offered in both a lead and excess position, provides follow form coverage and financial security. The excess product provides protection from catastrophic events covered in the underlying liability program.

Our flexible approach to Underwriting in conjunction with the ability to write excess of Hamilton Environmental or other carriers allows the insured to model how the product compliments their risk management profile.
