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. 8,9,10,11
Key Differences in Professional Liability (E&O) Insurance
How E&O Sits With Other Coverage
Chubb describes Pro ERM as one policy combining professional liability with media and cyber exposures for non-licensed professional-services firms. THREE instead lists Errors & Omissions among the coverage categories in a combined Business Owners Policy. Buyers seeking E&O alongside cyber and media can compare Chubb's named combination with THREE's broader package, but should check which categories appear on the actual quote. 3 7
Defense and the Limit Shown
Chubb says Pro ERM covers 100% of defense costs for covered claims worldwide, although its reviewed page gives no separate liability limit or retention. THREE's public E&O page likewise does not publish a separate E&O limit or deductible; it says those figures appear in the quote-specific summary. A buyer can compare defense-cost treatment only after seeing the proposed forms and figures together. 3 6
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Chubb which liability limit and retention apply to Pro ERM and whether worldwide defense costs are inside or outside that limit. 3
- Ask THREE for the quote summary showing E&O's separate limit and deductible, and verify E&O is selected in the BOP. 6 7
- Compare the specific cyber and media protections in Chubb's combined policy with the coverage categories and forms THREE proposes. 3 7
- Confirm which Pro ERM applicant profile fits your business: Chubb describes it for non-licensed professional-services firms, while THREE does not publish separate E&O eligibility rules. 3 7

The inspected sources report separate measures: NerdWallet’s 4.0/5 editorial rating is excluded from the source-rating average; Trustpilot displayed 2.5/5 from five user posts and BBB displayed 4.8/5 from 265 reviews. Trustpilot and BBB include different purchase, service and agent/intermediary interactions, not a verified common policyholder cohort. BBB separately lists complaints. Any source-rating average weights eligible platforms equally and is not a pooled, representative customer-experience estimate or a claims-quality measure.[4][3][1][2]

Chubb vs THREE by Berkshire Hathaway: Professional Liability (E&O) Insurance: documented features by provider
| Criteria | Chubb Pro ERM (Professional Enterprise Risk Management) | THREE Business Owners Policy |
|---|---|---|
| Role in This Line | Chubb underwrites professional errors and omissions coverage through Pro ERM, a single policy combining professional liability, media and cyber exposures for non-licensed professional-services firms. 3Company-reported. Cyber Insurance Coverage & Products page, Professional Enterprise Risk Management section. | 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. 7Company-reported. 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. 6Company-reported. 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 | Chubb says Pro ERM is available to non-licensed professional-services firms of all sizes, naming examples including associations, consultants, business process administrators, event planners, interior and graphic design firms, marketing and PR firms, printers, staffing firms, travel agents and trustees. 3Company-reported. Pro ERM Target Clients list. | 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. 7,5Not publicly disclosed. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms. |
| Coverage Features | Beyond the Cyber ERM base, Chubb says Pro ERM adds E&O coverage including personal injury from professional services, a broadened definition of professional services that expressly includes professional technology services, coverage for independent contractors performing duties on the insured's behalf, automatic additional-insured status for clients when required by contract, and coverage for professional disciplinary proceedings. 3Company-reported. Pro ERM Product Features list; subject to the policy as issued. | 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. 7,6Company-reported. 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 | 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. 3Company-reported. Pro ERM Product Features list. | 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. 7,6Not publicly disclosed. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible. |
| 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. 3Company-reported. Pro ERM Product Features list. | Confirm in your quote. |
| How to Apply | Agents and brokers can quote Pro ERM through Chubb's Cyber Central or Marketplace quoting platforms. 3Company-reported. Cyber Insurance Coverage & Products page quoting section. | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. 5Company-reported. 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. |
