Aon vs CFC: How Do They Compare for Professional Liability (E&O) Insurance?

Aon presents Professional Liability / E&O as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. ³Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement.

CFC sells professional errors & omissions as a modular package policy it calls "Professional services" (branded on the brochure as "Miscellaneous professional liability"), which pairs E&O with optional general liability, property and cyber add-ons rather than selling E&O alone. ^8,9Company-reported. Professional liability product page's "Professional services" tile and the miscellaneous professional liability brochure.

The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. ³Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement.

The reviewed professional liability page and brochure describe CFC as the policy designer and point of contact but do not name the insurer that carries the risk for this product. ^8,9Not publicly disclosed. Professional liability product page and professions brochure as read on 2026-09-23. CFC's own materials describe it as an underwriting manager rather than a risk-bearing insurer, so a specific carrier for this product would need to come from the quote or declarations.

Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. ³Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement.

CFC says it favors business, educational, environmental, food, HR, market-research, quality-assurance, security and traffic consultants, event organisers, freight brokers, loss adjusters, private investigators and trade associations, and ordinarily declines debt collectors, financial advisors, health and safety consultants, insurance agents, lawyers, mortgage brokers, pre-purchase home inspectors, stockbrokers, tour operators and valuers. ⁹Company-reported. Brochure's "What we love" and "What we ordinarily decline" lists; actual acceptance depends on individual underwriting.

Aon describes professional liability as addressing professional-services firms’ liability exposure and says it tailors coverage structures to a firm’s needs. It identifies E&O as a commonly used name for professional-liability insurance; actual policy terms are not stated. ³Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage.

CFC says the E&O cover includes breach of contract, bodily injury, property damage, vicarious liability of subcontractors, IP infringement, pollution liability, libel, slander, defamation, document loss and withheld fees, with worldwide legal cover. ⁹Company-reported. Brochure's "Comprehensive errors & omissions cover" and "Comprehensive legal cover" sections; exact wording and exclusions are set by the policy as issued.

Businesses can add a separate commercial general liability limit, property, and cyber and privacy liability to the E&O policy, plus optional umbrella liability that sits over the E&O and CGL layers. ⁹Company-reported. Brochure's "Modular package policy" and "Umbrella liability" sections; availability depends on underwriting.

The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. ³Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed.

CFC's brochure lists maximum limits of $10,000,000 for E&O, $6,000,000 for CGL and $5,000,000 for umbrella, with a $0 minimum deductible, minimum premiums starting at $475-$500 depending on the coverage part, and no revenue threshold for eligibility. ⁹Company-reported. Brochure's "Limits, deductibles, premiums, revenue threshold" section; the terms actually issued depend on underwriting.

Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. ³Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated.
