What Is Umbrella and Excess Liability Insurance?
Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. 9,10,11,12,13
Key Differences in Umbrella and Excess Liability Insurance
Underwriting and Placement Route
Chubb says it underwrites umbrella and excess liability directly, with options spanning small and midsized companies through global organizations. Its Express Umbrella platform lets appointed brokers reserve, quote, bind, and issue business online. Insureon markets commercial umbrella through its small-business quote channel and offers an online request, but its overview does not identify the insurer. If you need a broker to place directly with a named carrier or need a carrier identity early, ask how each route handles that step. 4 4 8 8
Segmented Casualty Options
Chubb describes separate umbrella and excess casualty options for large and national companies, mid-sized firms, energy, and construction, with its small-business Total Account Solution offering an additional liability layer. Insureon’s overview addresses businesses seeking additional liability protection but does not publish segment-specific eligibility or limits. A construction or energy buyer can ask Chubb which program matches its exposure; an Insureon applicant should confirm the underwriter and fit in the resulting quote. 4 5 8
