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

Named CNA programs and WTW brokerage work

CNA identifies Epack 3, EPS Plus, miscellaneous professional liability and Technology E&O, with dedicated claims and risk-control support for those professional-liability lines. WTW’s reviewed material describes professional-liability solutions within FINEX and errors-and-omissions for residential real-estate stakeholders, rather than a specific standard policy. If you need a defined CNA product, ask for its form; with WTW, clarify which market and wording the broker is seeking for your risk. [1] [6]

What happens between quote and issued policy

WTW’s terms say an insurer quote is not confirmation: after you order binding, WTW seeks a formal insurer commitment, typically a binder, and reviews issued documents against negotiated terms. CNA’s claims describe its own programs and support but do not explain that intermediary workflow. The practical comparison is product specificity versus a broker’s placement and document-checking process. Ask WTW who the proposed insurer is and what remains before binding; ask CNA for the declarations and final policy form. [1] [8]

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

  • Which CNA product form, claims contact and risk-control services are attached to your quote? [1]
  • Which insurer is WTW approaching, and what written confirmation marks coverage as bound? [6]

CNA identifies modular E&O products and dedicated claims and risk-control support; WTW describes intermediary placement, binding and review of policy documents against negotiated terms.
