HUB says its brokered policies are typically claims-made, may include prior acts or tail coverage and can cover contractors and temporary staff. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage")

[1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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")

## Key Differences in Professional Liability (E&O) Insurance

### Coverage and Policy Design

Aon describes professional liability as a structure tailored to firms’ needs, but does not specify a claims trigger or reporting period in its overview. HUB says the E&O policies it arranges are typically claims-made, with per-claim and aggregate limits, and can include prior-acts coverage to a retroactive date or tail coverage for an extended reporting period. HUB also says coverage can extend to contractors and temporary staff. Those options matter when switching carriers or staffing flexibly. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage")

### Buying Route and Terms

HUB names accounting, law, medical, financial-advisory, real-estate, architecture, engineering, consulting and contracting firms among typical E&O buyers, while Aon’s professional-services practice names law, accounting and consulting. HUB directs prospects to a broker and customizes for business size, industry, location and desired limits; Aon likewise describes advisor placement. Compare the retroactive date, tail price and insured-person wording on the actual policies. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask HUB for the retroactive date, tail options and whether your contractors are insured for their work. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage")
- Ask Aon to specify claims-made terms and coverage for temporary staff in the proposed form. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage")

## Offering Details

| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | HUB International Professional Liability (E&O) Insurance Brokerage |
| --- | --- | --- |
| 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..) | HUB brokers professional liability, which it also calls errors and omissions (E&O) insurance, rather than underwriting the coverage itself. [7](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: Professional liability and E&O product pages as read 2026-09-23; neither names an issuing insurer..) |
| 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..) | Neither the professional liability nor the E&O product page names an issuing insurer; HUB places this coverage with insurers that vary by client and placement. [7](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Not found in reviewed sources; scope: Checked both pages on 2026-09-23; no carrier is disclosed on either..) |
| 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..) | HUB names accounting, law, medical, financial-advisory, real estate, architecture and engineering, consulting, and contracting businesses as typical E&O buyers, and separately lists technology among nine industries its E&O practice serves. [7](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: Combined professional-liability and E&O industry lists; not a published underwriting appetite by state..) |
| 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..) | HUB says professional liability/E&O policies it arranges can cover defense costs, judgments, settlements and fines from allegations of misrepresentation, breach of professional services, wrongful business practices, misleading advice and conflict of interest, plus libel, slander or lost-profit claims; intentional acts and employment claims are typically excluded. [7](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") (Evidence: Company-reported; scope: Product-page coverage description; the issued policy and its exclusions control an actual claim..)<br><br>HUB says E&O policies are typically claims-made with per-claim and aggregate limits, can be structured with prior-acts coverage back to a retroactive date, and can offer tail coverage for an extended reporting period; coverage can extend to independent contractors and temporary staff performing work for the business. [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: E&O product-page structure description; specific limits and retroactive dates are set on the quote and declarations..) |
| 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..) | Confirm in your quote. |
| 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. | HUB directs prospects to connect with a broker; the pages describe professional liability/E&O policies as customized to business size, industry, location, risk base and desired limits, without an online quote flow. [7](https://www.hubinternational.com/products/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Brokers") [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: Product-page call to action and customization description as read 2026-09-23..) |
| Claims Support | Confirm in your quote. | HUB's E&O page tells policyholders to notify their broker and carrier as soon as possible after an incident and submit documentation including a narrative of the events leading up to the claim. [8](https://www.hubinternational.com/products/business-insurance/errors-and-omissions/ "Errors and Omissions (E&O) Insurance Coverage") (Evidence: Company-reported; scope: E&O product-page claims-notification guidance; a general process description, not an outcome measurement..) |
