Chubb vs 
HUB International Umbrella and Excess Liability Insurance
Chubb underwrites umbrella by company segment; HUB brokers the layer for transportation, healthcare, hospitality and other casualty industries.
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 HUB International?
HUB International is a North American insurance brokerage that arranges business insurance, employee benefits and related risk services through local offices and specialist practices. Smaller commercial accounts may be sent to Insureon for an online quote; other programs are handled by HUB advisors, with policy terms set by the insurers they use. 6,7,8
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. 10,11
Key Differences in Umbrella and Excess Liability Insurance
Who Carries the Risk Versus Who Places It
Chubb underwrites umbrella and excess liability. HUB International brokers umbrella and excess through its casualty practice rather than underwriting the coverage. The insurer on a HUB placement varies by client and program; HUB’s casualty page does not name that insurer. 4 9
How Each Splits the Audience
Chubb structures umbrella and excess casualty into options for large global and national companies, mid-sized companies, the energy industry, and construction. HUB says its casualty expertise, which includes this layer, spans transportation, construction, healthcare, hospitality, manufacturing/distribution and real estate. Construction appears in both descriptions; HUB’s list also names healthcare and hospitality, which Chubb’s reviewed segment list does not. 4 9
Claims and Risk Services Around the Layer
HUB says it applies risk-services, claims, litigation and analytics expertise across its casualty programs, which include umbrella and excess placements. For mid-sized companies, Chubb describes excess casualty alternatives with claims handling and timely service; for large global and national companies it specializes in lead umbrella and excess liability. Neither reviewed page publishes numeric umbrella or excess limits. 9 4
