What Are the Key Differences Between Chubb and WTW Professional Liability (E&O) Insurance?

E&O within a cyber, media and professional form

Chubb's Pro ERM combines professional liability, media and cyber for non-licensed professional-services firms, adding E&O features such as independent-contractor coverage and professional disciplinary proceedings. WTW's record identifies professional-liability solutions in FINEX and E&O for residential real-estate stakeholders, but does not describe a comparable combined form. Ask Chubb whether your work is treated as professional services and ask WTW which standalone or combined placement it proposes. [1] [9]

Defense costs and organization type

Chubb says Pro ERM covers 100% of defense costs for covered claims worldwide and targets non-licensed firms, including consultants, designers, staffing and travel businesses. WTW's source record gives a segment-specific residential E&O example within its broader FINEX practice. If you are a licensed professional, ask Chubb whether its eligibility restriction applies; for either quote, confirm whether defense costs reduce the limit. [1] [9]

What Should You Confirm in Chubb and WTW Professional Liability (E&O) Insurance Quotes?

  • Ask Chubb to confirm your licensing status, defense-cost treatment and the limit and retention on the issued form. [1]

  • Ask WTW which policy form and defense-cost structure apply to your profession and whether it is claims-made. [8]
