What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 8,9,10,11
Key Differences in Professional Liability (E&O) Insurance
Defense and Policy Structure
Chubb’s Pro ERM bundles professional liability with media and cyber and says it covers 100% of defense costs for covered claims worldwide. Zurich describes E&O in its modular Pro Plus suite, where coverage may include defense costs, court fees, settlements, and judgments. Ask both for the applicable limit and whether defense erodes it; the reviewed descriptions do not establish a direct limit comparison. 3 3 7 7
Eligible Professional Services
Chubb targets non-licensed professional-services firms, including consultants, event planners, marketing firms, staffing companies, and trustees. Zurich names technology, manufacturing, and third-party service providers for E&O. A licensed professional should check eligibility carefully: Chubb’s stated audience excludes licensed firms, while Zurich’s record names specific industry classes rather than a broad all-profession rule. 3 7

The available Zurich review evidence is mixed and comes from distinct populations: a car-rental-business editorial rating, broad global and U.S. review-platform snapshots, and a BBB business-profile grade. These are not a representative measure of every Zurich commercial policy or claim.[1][4][5][6][7]
