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. 7,8,9,10
Key Differences in Professional Liability (E&O) Insurance
Product Structure and Business Fit
A Pro Plus buyer can combine Zurich's admitted E&O—available in most states—with other modules in one policy; Zurich names technology, manufacturing, and third-party service providers as target classes. Markel's separate miscellaneous E&O page instead describes targeted small businesses up to $5 million in revenue and publishes a $2 million maximum. A buyer comparing standalone miscellaneous coverage with a broader package should ask which modules are selected and whether the particular service falls within Zurich's listed classes. 3 6
Claims and Covered Allegations
For a disputed professional service, Zurich names negligence, mistakes, or failure to deliver as allegations and lists defense costs, court fees, settlements, and judgments among potential costs; its E&O specialists coordinate with legal counsel. Markel's page identifies covered miscellaneous E&O claims but does not describe a claims team. Ask Markel how claims are handled and compare both policies' defense-cost treatment. 6 3
Limit and Availability
A buyer's state may determine whether Zurich's admitted E&O is available; the reviewed Zurich claim does not publish a limit. Markel provides a different reference point with a stated $2 million product maximum for miscellaneous E&O. Ask Zurich for the limit and form available in your state, and confirm whether Markel's stated ceiling applies to your class and requested terms. 3 6
