# Chubb vs Heffernan Insurance Brokers Professional Liability (E&O) Insurance

Chubb underwrites a combined professional liability, media and cyber policy; Heffernan places E&O as one line in a custom small-business package.

## Research Scope and Use

Use this comparison to evaluate Chubb and Heffernan Insurance Brokers 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

Chubb underwrites Pro ERM, a single policy bundling professional liability with media and cyber cover for non-licensed professional-services firms. Heffernan's small-business division places errors and omissions as one coverage among several, without a dedicated product page or published limits. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## 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. [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

### Who Carries the Risk

Chubb underwrites Pro ERM itself, combining professional liability, media and cyber exposures in one policy built for non-licensed professional-services firms. Heffernan's small-business division shops errors and omissions coverage to outside insurers as part of a broader package, rather than issuing the policy. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### What the Product Covers

Chubb names specific Pro ERM features beyond a base E&O form: personal-injury claims from professional services, a broadened definition of professional services that reaches technology work, coverage for independent contractors, automatic additional-insured status for clients when a contract requires it, and coverage for professional disciplinary proceedings. Heffernan's reviewed page describes only the general purpose of the coverage, protecting against claims tied to problems with a company's product or service that cause a client financial loss, without listing comparable features. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### Who Each One Serves

Chubb names a specific set of non-licensed professional-services buyers for Pro ERM: associations, consultants, business process administrators, event planners, interior and graphic design firms, marketing and PR firms, printers, staffing firms, travel agents and trustees. Heffernan's small-business division describes its buyer base more broadly, spanning sole proprietors through fast-growing companies in construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, and offers to custom-design a package for industries not already listed. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

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

- Ask Chubb for the Pro ERM liability limit and retention; the reviewed page states 100% defense-cost coverage worldwide but does not publish a separate limit figure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Heffernan which insurer it would place the policy with and what limits that insurer offers, since the small-business page names neither. [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Confirm whether your business qualifies as "non-licensed" under Chubb's Pro ERM eligibility criteria, since licensed professionals may need a different Chubb product. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Heffernan whether your industry is already on its coverage list or would require a custom-designed package, and how that affects turnaround time. [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
