## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [9](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [10](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [11](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [12](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

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

### Underwriter or broker placement

Travelers says it underwrites E&O as a standalone policy written for the buyer’s profession; Aon describes a global brokerage and advisory practice. Ask Travelers which issuing entity appears on the policy, and ask Aon which insurer will take the placement. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")

### Separate professional products

Travelers lists E&O products for accountants, design professionals, lawyers, real estate and other professions. Aon names law, accounting and consulting firms as its practice audience. If your occupation is specialized, ask both providers how the offered form addresses its particular work. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")

### Profession-specific coverage wording

Travelers says its E&O coverage can be customized to profession-specific risks and describes defense and settlement costs for allegations of inadequate work or negligent service. Aon says it tailors coverage structures but does not enumerate the same allegations. Compare the forms against client contract duties. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")

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

- Ask Aon to confirm the quoted policy form, retroactive date and covered allegations; its offering says 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")
- Ask Travelers to confirm the quoted policy form, retroactive date and covered allegations; its offering says e&O as covering the costs of client allegations of inadequate work, negligent actions or failure to meet the expected level of service, including legal defense and settlement costs, and says coverage can be customized to the risks of a specific profession.

## Aon vs Travelers Professional Liability (E&O) Insurance Compared

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Travelers Errors and Omissions Insurance |
| --- | --- | --- |
| Role in This Line | 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | Travelers underwrites errors and omissions insurance as one of several management and professional liability products, sold as a standalone policy written for the buyer's profession rather than bundled with other lines by default. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") [8](https://www.travelers.com/business-insurance/professional-liability-insurance "Management and Professional Liability Insurance") (Evidence: Company-reported; scope: E&O and management-liability product pages, as read on 2026-09-23..) |
| Issuing 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: 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 E&O page's footer names Travelers Casualty and Surety Company of America and its property-casualty affiliates, but Travelers also states the material does not amend any issued policy, so the exact issuing entity for a given E&O product depends on the policy. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: Footer disclosure on the errors-and-omissions page..) |
| Who It’s For | 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | Travelers offers separate E&O products by profession, including accountants, design professionals, lawyers, real estate professionals, insurance professionals, life/accident/health insurance agents, managed care organizations, financial institutions and a miscellaneous professional liability option for other client-facing professionals. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: Product-selection list on the E&O page..) |
| Coverage Features | 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: 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..) | Travelers describes E&O as covering the costs of client allegations of inadequate work, negligent actions or failure to meet the expected level of service, including legal defense and settlement costs, and says coverage can be customized to the risks of a specific profession. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: E&O overview and video transcript; exclusions and limits are not detailed on this page and depend on the policy as issued..) |
| Limits and Retentions | 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | The reviewed E&O page does not publish limit or retention amounts for any of its professional-liability products. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Not publicly disclosed; scope: Errors-and-omissions page as read on 2026-09-23..) |
| Risk 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. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Confirm in your quote. |
| How to Apply | Confirm in your quote. | Travelers directs buyers to talk to an independent agent to place E&O coverage, and tells agents to use its management-and-professional-liability applications and forms library. [7](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") [8](https://www.travelers.com/business-insurance/professional-liability-insurance "Management and Professional Liability Insurance") (Evidence: Company-reported; scope: E&O page CTA and video transcript..) |
