Aon vs Baldwin: Professional Liability / E&O Insurance

What Are the Key Differences Between Aon and The Baldwin Group Professional Liability (E&O) Insurance?

Coverage Structure and Evidence

Aon describes professional liability as addressing professional-services firms’ liability exposure and says its advisors tailor structures to firm needs. The Baldwin Group names accountants, architects, engineers, financial advisers, lawyers, consultants and surveyors among its professional-services clients, but its reviewed page does not define covered errors, insured services or claims-made conditions. A firm in one of those professions can ask Baldwin to identify the applicable policy form; Aon’s description offers a tailoring discussion without specifying the form either. [1] [5]

Buyer Fit and Placement

Both are broker/advisory routes rather than identified policy issuers, and neither reviewed record states a buyer-specific limit, deductible or exclusion schedule. Baldwin describes tailored insurance and risk-mitigation guidance, while Aon cites industry knowledge, data and tools for professional-services decisions. These service descriptions do not establish broader coverage. Ask each broker to show the insured services definition and compare limits, retroactive date, defense treatment and exclusions in the actual quote. [1] [5]

What Should You Confirm in Aon and The Baldwin Group Professional Liability (E&O) Insurance Quotes?

Ask Baldwin which professional services are insured and request the form, limit and retroactive date. [1] [5]
Ask Aon to identify the carrier and show how the proposed terms match your client contracts. [1] [5]

Aon says it tailors professional-liability structures for professional-services firms. The Baldwin Group serves accountants, architects, advisers, lawyers and other professionals but does not publish E&O triggers or limits.
