### Aon

Role: Broker.

Broker Spot Score: **6.7/10** (partial score; 70% of this role's weighting included). Assessed 2026-09-29; review due 2026-10-29. Excluded factors: Carrier-Network Strength (The supplied evidence did not support a score for Carrier-Network Strength; this factor is excluded, not scored as zero. Canonical evidence gaps: The FCA register could not be loaded, so Aon UK Limited's FCA number and permissions are company-reported.; No NAIC, NIPR or other state producer search was completed for Aon's U.S. entities beyond the two Texas orders; current status of those Texas licenses was not re-checked.; Aon does not publish a named list of insurers behind its placements, so the network view rests on its concentration statement.; The Central Bank of Ireland, Lloyd's and other state enforcement records were not searched exhaustively.; Placement-specific compensation is not published; only the general categories are.).

## Optional Spot Service Handoff

Spot can help prepare applications, coordinate brokers, and compare proposals. If that work is needed, collect the company's task, known deadline, current broker, and open questions for a [free consultation](https://spot.insure/pricing.md). The company decides what to buy; Spot does not automatically bind coverage.

## Key Differences Between Aon and THREE

### Business Roles and Access to Insurers

Aon’s documented role shapes who handles underwriting and how you reach a policy.

Aon’s U.S. Commercial Risk terms describe Commercial Risk Solutions U.S. as broker of record for certain insurance programs. Separate electronic-delivery terms name Aon Risk Services Companies, Inc. acting for itself and licensed brokerage subsidiaries to deliver arranged policies; the terms define an insurer as the policy issuer and risk bearer. These group-level descriptions do not identify the producer or authority for a particular placement. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/about/leadership-and-governance/aon-commercial-risk-us-electronic-disclosure-and-consent-terms "Aon Commercial Risk U.S. Electronic Disclosure and Consent Terms") (Evidence: Company-reported; scope: Company-reported U.S. Commercial Risk brokerage and electronic-delivery terms; certain programs only. No specific insured, licensed producer, appointment, policy issuer, state authority or placement was matched.; verified: 2026-09-29.)

THREE documents its own insurance role and access arrangement.

THREE is the commercial brand and product form used by Berkshire Hathaway Direct Insurance Company (BHDIC), which identifies itself as doing business as THREE and names itself as issuer on the sample THREE policy. THREE’s FAQ describes THREE or THREE Insurance as the product name, not a separate insurer. The state-specific issued policy controls. [15](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [16](https://threeinsurance.com/the-policy "The Policy") [17](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: U.S. THREE commercial-insurance brand and sample policy; current company identity pages checked 2026-09-28. Company-reported legal disclosure; the state-specific issued policy controls the buyer’s contract.; verified: 2026-09-28.)

### Business Fit and Application

Compare the provider roles and application paths with your operation; neither route establishes applicant eligibility.

These entry points show how to start; they do not confirm eligibility or that coverage has been bound.

For certain U.S. Commercial Risk programs, Aon says it consults with the client about market conditions, insurers to approach and program strategy, helps prepare underwriting information and applications, and obtains the client’s instructions to bind specific programs based on Aon’s proposal. The client signs applications that require a signature.

THREE directs prospective customers to an online quote flow and says licensed Small Business Advisors can help them start or continue the process; the company’s FAQ also describes a phone quote and says an unfinished quote can be saved and resumed. This documents quote routes, not online purchase or binding by an individual customer. [15](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [17](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: U.S. business insurance quote application. Company-described online and phone process; no customer form was submitted and no binding outcome was tested.; verified: 2026-09-28.)

## What to Confirm in Quotes

Ask Aon which programs and markets are in scope and how compensation works. Ask THREE to identify the insurer and confirm whether its product covers the full operation. Ask each provider to identify the proposed insurer, exact forms and endorsements, any intermediary or account service contact, and the steps required to bind. Compare premiums only after matching limits, retentions, exclusions, policy periods, taxes and fees.
