Key Differences in Professional Liability (E&O) Insurance

Combined coverages and target professions

Chubb underwrites Pro ERM as one policy combining professional liability, media and cyber for non-licensed professional-services firms. It adds professional technology services, independent contractors, contract-required additional insureds and disciplinary proceedings. Markel describes miscellaneous E&O for professional-services claims in targeted small-business industries and states a $2 million maximum. Compare whether one combined form fits your exposures or whether you need a separately placed E&O product. 3 7

Defense costs and counsel

Chubb says Pro ERM covers 100% of defense costs worldwide and gives policyholders access to experienced professional-liability counsel, though its page does not publish a separate limit or retention. Markel publishes a maximum but its reviewed claim does not describe comparable counsel access. For defense-heavy risks, ask how costs erode each limit and who selects counsel. 3 7

What to Confirm in Professional Liability (E&O) Insurance Quotes

  • Ask Chubb how the combined limit is shared across E&O, media and cyber and whether your profession is eligible.
  • Ask Markel for defense-cost treatment, counsel selection and the limit offered for your services.
