Aon vs Beazley: Professional Liability / E&O Insurance

An accounting firm falls inside Aon's named audience but outside Beazley's MediaTech form, which excludes accountants and architects; Beazley fits small tech and media businesses wanting E&O bundled with cyber.

Kearny Risk organizes these comparisons for firms whose advice, content or technology creates professional exposures.Research updated 2026-09-30

Aon describes tailored professional-liability structures without naming terms. Beazley’s MediaTech form bundles professional services with tech E&O, media and cyber, and defines covered wrongful acts.

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

Form and Coverage Scope

Aon says it tailors professional-liability structures to a firm’s needs, but does not name a policy form or specify covered acts. Beazley places professional E&O inside MediaTech, a small-business form that also includes technology E&O, media and cyber. Its sample form covers negligent acts, errors, omissions, misstatements or unintentional contract breaches in fee-based services. A buyer choosing the bundle should check whether those services match its actual work. [1] [3]

Buyer Fit and Policy Terms

The Beazley sample excludes professional services by several licensed occupations, including accountants, architects, healthcare providers, lawyers and insurance agents. Coverage is claims-made and reported, defense costs reduce the limit, and the policy aggregate is shared with media and cyber unless declarations separate it. Aon’s overview does not state comparable triggers or exclusions. Ask Aon to provide the form and limit structure before comparing it with MediaTech. [1] [3]

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

  • Ask Beazley whether your licensed services are excluded and whether a separate aggregate is declared. [1] [3]
  • Ask Aon for the covered-services definition, reporting terms and interaction between E&O and other policies. [1] [3]

Areas of coverage

Aon

  • role: 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. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement.company-reportedSource ↗
  • eligibility: 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. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗
  • services: 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. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated.company-reportedSource ↗
  • insurer: 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. 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.not-foundSource ↗
  • limits: 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. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed.not-disclosedSource ↗

Beazley

  • role: Beazley sells professional errors and omissions coverage bundled inside MediaTech, a single small-business form that also includes technology E&O, media liability and cyber coverage. It is not sold as a standalone professional-liability policy for this segment. US small-business MediaTech product page; does not address any larger-account professional liability program Beazley may write separately.company-reportedSource ↗
  • insurer: Beazley's posted Digital MediaTech Application names Beazley Insurance Company, Inc. as the insurer on its cover page. The actual issuing entity for a given policy is confirmed on the quote and declarations, not the blank application. Application form F00859, 042022 edition; not a regulator record and not evidence of the entity for every state or route.company-reportedSource ↗
  • coverage: The sample MediaTech form covers a Tech & Professional Services Wrongful Act: a negligent act, error, omission, misstatement or unintentional breach of contract in rendering Professional Services, defined as services performed for others for a fee. Sample policy form F00731, 022019 edition, insuring agreements and definitions; the issued policy's wording and any endorsements control.company-reportedSource ↗
  • coverage: The sample form's definition of Professional Services excludes services performed as an accountant, architect, surveyor, health care provider, lawyer, insurance or real estate agent or broker, or civil or structural engineer, so those licensed professions are not covered by this professional E&O trigger. Sample policy form F00731, 022019 edition, Professional Services definition; a business in one of these excluded professions would need different coverage even if it buys MediaTech.company-reportedSource ↗
  • limits: Coverage is claims-made and reported: it responds only to claims first made and reported during the policy period (or a purchased Optional Extension Period), and defense costs reduce the available limit. A buyer can purchase an Optional Extension Period (a tail) for additional premium after non-renewal or cancellation. Sample policy form F00731; application form repeats the same notice; specific tail pricing and duration are set in the declarations, not disclosed publicly.company-reportedSource ↗Source ↗
  • limits: Unless the declarations list a separate amount, each insuring agreement in the sample form (including the professional-liability trigger) shares the same Policy Aggregate Limit of Liability with the policy's media and cyber coverages rather than carrying its own dedicated limit. Sample policy form F00731, 022019 edition, Limit of Liability and Coverage section; actual sublimits depend on what is purchased and shown on the declarations.company-reportedSource ↗
  • application: Beazley's MediaTech application asks applicants to describe the professional and technology services they perform, disclose employee count and multi-year US and non-US revenue, and state whether written client contracts include scope-of-work, damages-cap and consequential-damages-disclaimer provisions. Application form F00859, 042022 edition, General Information, Revenue Information and Contractual Controls sections; a completed application does not establish acceptance.company-reportedSource ↗
  • claims: Beazley says its cyber and tech claims team, including experienced litigators, has handled thousands of E&O claims, which it describes as including implementation errors alongside software failures and IP disputes. MediaTech product page claims paragraph; outcome and volume figures are Beazley's own description and not independently verified.company-reportedSource ↗
