# Chubb vs Gallagher Professional Liability (E&O) Insurance

Gallagher recommends E&O for licensed professions that Chubb's Pro ERM eligibility excludes by design.

## Research Scope and Use

Use this comparison to evaluate Chubb and Gallagher for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Gallagher recommends its E&O coverage for lawyers and other licensed professions, while Chubb positions Pro ERM specifically for non-licensed professional-services firms instead.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

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

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](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

### Licensed Professions Land on Opposite Sides

Gallagher recommends E&O for lawyers, insurance professionals and other licensed businesses among the industries it names. [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Chubb positions Pro ERM specifically for non-licensed professional-services firms, naming associations, consultants and event planners as examples instead. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### What Each Says the Policy Covers Beyond Negligence

Gallagher says its E&O coverage responds to alleged negligence, personal injury, copyright infringement and punitive damages. [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Chubb's Pro ERM page also lists personal injury among its coverage features, but describes disciplinary-proceedings defense and a broadened professional-services definition rather than copyright infringement or punitive damages specifically. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Covering Contractors and Temporary Staff

Gallagher says its E&O coverage can respond to claims tied to past work, temporary staff or independent contractors. [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Chubb's Pro ERM instead builds coverage for independent contractors performing duties on the insured's behalf directly into the policy's features. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

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

- Confirm whether your business qualifies as "non-licensed" for Chubb's Pro ERM eligibility, or whether Gallagher's broader licensed-profession list fits instead. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")
- Ask Gallagher for actual limit and premium figures, since its page directs buyers to request a quote instead of publishing them. [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")
- Confirm Chubb's actual liability limit for Pro ERM, since the reviewed page names defense-cost treatment but not a limit figure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Get the issuing insurer for Gallagher's placement; the reviewed page names no carrier. [10](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")

Note this record excludes medical malpractice, which the page treats as a separate specialized coverage covered under its own line..)<br><br>Gallagher's small-business team says the E&O market has seen consistent rate increases that have started to moderate, driven by higher claim frequency, litigation costs and a more litigious environment, and that insurers are more selective and require more detailed underwriting information.

| Limits and Retentions | Chubb says Pro ERM includes coverage for 100% of defense costs for covered claims worldwide, but the reviewed page does not publish a separate liability limit or retention.

| Risk Services | Chubb says Pro ERM policyholders get access to legal counsel with extensive professional-liability experience, in addition to the general cyber-incident-response services shared with Cyber ERM.
