Chubb vs 
Gallagher Umbrella and Excess Liability Insurance
Chubb underwrites lead umbrella and excess casualty; Gallagher places customized excess programs with gap analysis and loss-control advocacy.
What Is Chubb?
Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company. 1,2,3
What Is Gallagher?
Gallagher is a business-insurance broker and risk-management consultancy. Its technology practice serves startups through global enterprises, alongside a separate small-business offering for IT professionals and an executive-risk practice covering D&O and transaction-related coverages. Woodruff Sawyer is now part of Gallagher. 6,7,8,9,10
What Is Umbrella and Excess Liability Insurance?
Commercial umbrella insurance can provide additional liability limits above scheduled underlying policies for covered claims. Don't assume umbrella and excess liability are the same coverage — the labels aren't proven synonyms. 12,13
Key Differences in Umbrella and Excess Liability Insurance
Writing Company Versus Casualty Broker
Chubb underwrites umbrella and excess liability across smaller firms through global multinationals. Gallagher’s Casualty practice places umbrella and excess with outside carriers as one line in a broader casualty program and does not underwrite the policy. Gallagher’s page does not name the issuing insurer; Chubb is the underwriter in its own description. 4 11
Lead Umbrella Language Versus Alternative-Risk Design
For large global and national companies, Chubb specializes in lead umbrella and excess liability; for mid-sized companies it offers excess casualty alternatives with claims handling. Gallagher groups umbrella and excess with automobile, workers’ compensation and general/product liability and offers customized excess casualty program design and non-traditional alternative risk programs, without describing attachment points. 4 11
Broker Tools and Client Services
Chubb offers Express Umbrella so appointed brokers can reserve, quote, bind and issue, and buyers can request a quote online or through an appointed agent. Gallagher describes pre-renewal meetings with finance, HR, operations and risk stakeholders, gap analysis and contract/form review, and a claims and loss-control advocacy group. Neither page publishes specific limit amounts. 4 11
