## 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

### A Dedicated Page Versus One Line in a List

Heffernan names errors and omissions as one coverage among several its small-business division places for clients, without a dedicated E&O product page: [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")


Heffernan lists errors and omissions among the coverages its small-business division places for clients, shopping the line with insurers rather than underwriting it. [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; no dedicated professional-E&O product page was found..)

Gallagher instead runs a standalone Errors and Omissions Insurance page with its own coverage description, eligibility list and market-conditions section. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")

### Who Each Page Names as a Fit

Gallagher recommends E&O for small businesses in technology, insurance, accounting, tax, wealth management and legal services, naming doctors, lawyers, accountants, nurses, caregivers, counselors, social workers and engineers. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Heffernan instead says its small-business division serves sole proprietors through fast-growing companies across construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, without naming individual professions. [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### How Coverage Is Described

Gallagher describes E&O as protecting against client charges of negligence or injury tied to professional services, covering losses, attorney fees and court costs regardless of fault, and naming alleged negligence, personal injury, copyright infringement, punitive damages, and claims against past work, temporary staff or independent contractors. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Heffernan's page instead describes the coverage in one sentence, as protecting against claims for problems with a company's product or service that result in a client's financial loss, without listing specific scenarios. [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

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

- Ask Heffernan whether it will build a dedicated E&O submission for your profession, since its page groups the coverage with other small-business lines. [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Ask Gallagher whether the market conditions it describes, rate increases and more selective underwriting, affect the specific quote you receive. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")
- Neither page names an issuing insurer; ask both Gallagher and Heffernan which carrier would underwrite your policy. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Gallagher's reviewed page publishes no limit or premium figures, and Heffernan's reviewed page publishes none either; request specific figures from both. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [10](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
