[3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")

## 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. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](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

### Package Category and Broker Placement

THREE presents E&O as a category inside its combined Business Owners Policy and directs small businesses to an online quote or licensed advisor. WTW's North American Corporate Risk & Broking terms describe WTW as the client's insurance intermediary; E&O appears within its financial-lines practice and residential real-estate offering. A buyer comparing these approaches should clarify whether WTW is arranging a standalone placement for the exposure, while THREE is quoting its BOP package. [3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [1](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K")

### Binding and Policy Document Review

WTW says an insurer quote alone does not confirm coverage; after the client orders binding, WTW seeks a formal insurer commitment, typically a binder, and reviews the binder, policy and endorsements against negotiated terms. THREE says the issued declarations, forms and endorsements govern its sample-based policy illustration. In both cases the buyer should wait for issued evidence, but WTW specifically documents an intermediary review step that can be checked against negotiated terms. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [2](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 WTW which insurer will issue the placement, what limit and retention apply, and whether it will review the binder and policy against negotiated terms. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")
- Ask THREE to identify E&O in the BOP quote and supply the issuer, line limit, deductible and final endorsements. [3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [2](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")
- Confirm the WTW engagement is governed by the North American terms reviewed here, and request the relevant professional-services form before comparing wording. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW")

## Offering Details

| Criteria | THREE Business Owners Policy | WTW Professional Errors and Omissions Brokerage |
| --- | --- | --- |
| Role in This Line | 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. [3](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..) | Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Terms for applicable North American Corporate Risk & Broking engagements. WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement..) |
| Issuing Insurer | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [2](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..) | The reviewed WTW sources do not identify an issuing insurer for a specific professional errors omissions placement. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW") (Evidence: Not publicly disclosed; scope: This is a gap in the cited marketing, annual-report, and brokerage materials; it does not mean WTW lacks insurer markets. Confirm the carrier on the quote and issued policy..) |
| Who It’s For | 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. [3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [1](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..) | Confirm in your quote. |
| Coverage Features | 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. [3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [2](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..) | WTW's FY2024 annual report describes professional-liability solutions within FINEX; its residential practice lists errors-and-omissions among financial lines for residential real-estate stakeholders. [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW") (Evidence: Company-reported; scope: The report is historical and group-level; the residential E&O reference is segment-specific and based on retained official indexed text. Neither establishes current terms or eligibility outside that segment..) |
| Limits and Retentions | 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. [3](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [2](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..) | The reviewed sources do not state a buyer-specific professional errors omissions limit, retention, or deductible. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW") (Evidence: Not publicly disclosed; scope: No limit or deductible is inferred from general marketing or WTW's brokerage role; the insurer's quote and issued forms control..) |
| Risk Services | Confirm in your quote. | WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Broker document-review process under the cited terms, when WTW handles this line's placement. It does not certify that a policy covers a claim or replace the issued wording..) |
| How to Apply | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [1](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..) | WTW's North American terms say an insurer quote is not confirmation of coverage; if the client orders binding, WTW seeks a formal insurer commitment, typically a binder. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Applies to placements governed by the cited North American Corporate Risk & Broking terms.
