## 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. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](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

### Broad Brokerage Placement and Package Category

Heffernan places E&O by shopping the coverage with insurers and serves businesses from sole proprietors to fast-growing companies across industries such as construction, food, healthcare, hospitality, technology and transportation. THREE instead lists E&O as a category inside its combined Business Owners Policy. The first route lets a buyer discuss a tailored placement across a broad business roster; the second starts with a package quote, so confirm whether E&O is selected for the specific operation. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### What the Public Pages Say About E&O Scope

Heffernan frames E&O around a product or service problem that causes a client's financial loss. THREE identifies E&O as a marketed BOP coverage category, but its public product description does not set out separate E&O eligibility rules or limits. A buyer should give both quote teams the actual services and contract requirements, then compare the written insuring agreement and line amount rather than relying on the labels. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

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

- Ask Heffernan which insurer it proposes, and request the E&O limit, retention and premium because its public page gives no figures. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Ask THREE to show E&O as included in the BOP and identify the separate limit, deductible and eligibility basis in the quote. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")
- Compare whether each form responds to the particular client financial-loss scenario arising from your services. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## Offering Details

| Criteria | Heffernan Professional Errors and Omissions Brokerage | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Heffernan lists errors and omissions among the coverages its small-business division places for clients, shopping the line with insurers rather than underwriting it. [4](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..) | THREE presents Errors and Omissions as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | Confirm in your quote. | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Heffernan's small-business division says it serves sole proprietors through fast-growing companies across industries including construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, and will custom-design a package for industries not listed. [4](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; not exclusively E&O-specific, but describes the buyer base for the page listing this coverage..) | The reviewed product page does not state separate eligibility rules for Errors and Omissions; the general quote and advisor route is not proof that a particular business qualifies for it. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Heffernan describes errors and omissions coverage as protecting against claims for problems with a company's product or service that result in a financial loss to a client. [4](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; the page does not list specific exclusions, claims-made versus occurrence form, or endorsements..) | THREE's Business Owners Policy page lists Errors & Omissions among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Errors and Omissions. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | The reviewed page does not publish limits, retentions, or premium ranges for errors and omissions coverage. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Not publicly disclosed; scope: Small Business Insurance page as read on 2026-09-23..) | The reviewed public product page does not state a separate limit or deductible for Errors and Omissions; THREE says the quote-specific insurance summary lists limits and deductibles. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| How to Apply | Heffernan directs small-business buyers to contact the firm's small-business division to request a quote and says it will research and build a custom package for industries not already listed. [4](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..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Errors and Omissions will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
