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
Combined policy and professional services
Chubb underwrites Pro ERM as one policy combining professional liability, media and cyber for non-licensed professional-services firms. It expressly includes professional technology services, independent contractors and automatic client additional-insured status when required by contract. Simply Business lists consultants, IT professionals, real-estate agents and bookkeepers as possible E&O buyers, subject to carrier eligibility. Confirm whether the buyer’s licensed status or client contract changes the available form. 4 7
Defense costs and purchase route
Chubb says Pro ERM covers 100% of defense costs for covered claims worldwide and provides access to experienced professional-liability counsel, though the reviewed page does not publish a separate limit or retention. Simply Business describes attorney fees and other legal costs as potentially covered under policy wording. Ask for the defense-cost treatment and declarations limits on each proposal. 3 6
