What Are the Key Differences Between HUB International and THREE by Berkshire Hathaway Professional Liability (E&O) Insurance?

Claims-Made Structure and Prior Work

HUB says E&O policies are typically claims-made, can include prior-acts coverage back to a retroactive date, and may add tail coverage for an extended reporting period. It also says the policy can extend to independent contractors and temporary staff doing work for the business. THREE markets E&O within its BOP but does not explain a separate trigger or prior-acts treatment on the public product page. This distinction matters when work predates the policy or a contractor delivers client services: compare dates and insured-person wording in the proposed forms. [5] [1] [3]

Claims Notification Route

HUB instructs policyholders to notify both broker and carrier as soon as possible and submit a narrative of events with supporting documents. THREE describes reporting claims online or by phone, followed by an assigned account manager for questions and updates. The practical check is who receives notice first and what deadline applies under each issued policy. [5] [3]

What Should You Confirm in HUB International and THREE by Berkshire Hathaway Professional Liability (E&O) Insurance Quotes?

  • Ask HUB for the retroactive date, tail options, contractor and temporary-staff treatment, and carrier contact for notice. [5]
  • Ask THREE to identify E&O's reporting trigger, retroactive date, limit and deductible in the issued package documents. [1] [3]
  • Compare the notice deadline and required incident narrative with HUB's broker-and-carrier instructions and THREE's online or phone route. [5] [3]

Areas of coverage

HUB International

  • role: HUB brokers professional liability, which it also calls errors and omissions (E&O) insurance, rather than underwriting the coverage itself. Professional liability and E&O product pages as read 2026-09-23; neither names an issuing insurer.company-reportedSource ↗Source ↗
  • coverage: HUB says professional liability/E&O policies it arranges can cover defense costs, judgments, settlements and fines from allegations of misrepresentation, breach of professional services, wrongful business practices, misleading advice and conflict of interest, plus libel, slander or lost-profit claims; intentional acts and employment claims are typically excluded. Product-page coverage description; the issued policy and its exclusions control an actual claim.company-reportedSource ↗
  • eligibility: HUB names accounting, law, medical, financial-advisory, real estate, architecture and engineering, consulting, and contracting businesses as typical E&O buyers, and separately lists technology among nine industries its E&O practice serves. Combined professional-liability and E&O industry lists; not a published underwriting appetite by state.company-reportedSource ↗Source ↗
  • coverage: HUB says E&O policies are typically claims-made with per-claim and aggregate limits, can be structured with prior-acts coverage back to a retroactive date, and can offer tail coverage for an extended reporting period; coverage can extend to independent contractors and temporary staff performing work for the business. E&O product-page structure description; specific limits and retroactive dates are set on the quote and declarations.company-reportedSource ↗
  • insurer: Neither the professional liability nor the E&O product page names an issuing insurer; HUB places this coverage with insurers that vary by client and placement. Checked both pages on 2026-09-23; no carrier is disclosed on either.not-foundSource ↗Source ↗
  • claims: HUB's E&O page tells policyholders to notify their broker and carrier as soon as possible after an incident and submit documentation including a narrative of the events leading up to the claim. E&O product-page claims-notification guidance; a general process description, not an outcome measurement.company-reportedSource ↗
  • application: HUB directs prospects to connect with a broker; the pages describe professional liability/E&O policies as customized to business size, industry, location, risk base and desired limits, without an online quote flow. Product-page call to action and customization description as read 2026-09-23.company-reportedSource ↗Source ↗

THREE by Berkshire Hathaway

  • role: 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. Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗Source ↗
  • insurer: The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. 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.company-reportedSource ↗
  • application: THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. 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.company-reportedSource ↗
  • limits: 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. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible.not-disclosedSource ↗Source ↗
  • eligibility: 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. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms.not-disclosedSource ↗Source ↗

HUB brokers E&O and describes claims-made structures with retroactive dates, tail coverage, and potential coverage for temporary staff and contractors. THREE lists E&O within its Business Owners Policy but leaves separate line terms to the quote and issued form.
