## THREE by Berkshire Hathaway Reviews

Review Score: 7.3 / 10 from 2 rated sources, equally weighted.

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.

A listing may be arranged through an insurer or partner. “Not listed” means this catalogue has no separate offering recorded; ask the provider whether it can quote the coverage and request the policy terms.



## 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 CNA and THREE



### Application and Ongoing Service

Compare the application and service routes 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. [3](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [36](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [36](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [45](https://threeinsurance.com/business-owners-policy "Business Owners Policy | THREE") [3](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [7](https://www.cna.com/claims-center "Report an Insurance Claim") [38](https://threeinsurance.com/faqs "FAQs: Understanding THREE") [40](https://threeinsurance.com/claims "Filing a Claim: Call to get started")

CNA directs small-business buyers to work with an agent. CNA also says its U.S. offices work with independent agents and brokers to provide policyholder service and insurance solutions. [3](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [4](https://www.cna.com/about/locations/us "United States") (Evidence: Company-reported; scope: CNA’s stated U.S. small-business route and U.S. agency relationships. These sources do not establish that every CNA product requires an agent or that buyers can complete a purchase directly online.; verified: 2026-09-28.)

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. [36](https://threeinsurance.com/ "THREE by Berkshire Hathaway — small business insurance") [38](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.)

### Servicing and Claims

CNA says CNA Central gives small-business agents access to policy documents, loss runs, and claims information. CNA’s 2022 agent guide says agents can access policy, billing, and claims information and download new-business, renewal, and endorsement documents. This describes agent access, not automatic renewal or a guaranteed renewal offer. [3](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [5](https://www.cna.com/sites/default/files/assets/28007e1c-9e6b-4606-8060-670a9fb4b465/2589-SB%2BSmall%2BBusiness%2BCNA%2BCentral%2Bguide_2022.pdf?fid= "Small Business | CNA Central Agent Guide") (Evidence: Company-reported; scope: Small-business agent servicing through CNA Central, based on the current U.S. small-business page and a guide copyrighted 2022. The guide’s detailed portal functions are historical interface descriptions; renewal-document access does not establish that every policy renews or will receive an offer.; verified: 2026-09-28.)

THREE says policyholders can submit policy-change requests through My THREE Online or contact a Small Business Advisor. Its FAQ lists account/contact and billing tasks, vehicle and location changes, and certificate requests; it says vehicle and location requests are reviewed and processed by its team. The page does not establish automatic approval or effective dates for changes. [38](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: Company-described servicing routes and request types for THREE policyholders; submitted requests may be reviewed and processed, and approval/effective dates are not established.; verified: 2026-09-28.)

CNA’s Claims Center provides an online entry point where a visitor enters a few details to learn claim-reporting options and lists phone help Monday through Friday, 8 a.m.–8 p.m. Eastern. The page does not establish complete online filing or claim outcomes. [7](https://www.cna.com/claims-center "Report an Insurance Claim") (Evidence: Company-reported; scope: CNA U.S. Claims Center page accessed 2026-09-28; policy-specific reporting instructions, completion of a claim online, and claim outcomes are not established by this page.; verified: 2026-09-28.)

THREE says policyholders can report a claim online through My THREE Online or by phone; after submission, it assigns an account manager as the contact for claim questions and updates. [40](https://threeinsurance.com/claims "Filing a Claim: Call to get started") [38](https://threeinsurance.com/faqs "FAQs: Understanding THREE") (Evidence: Company-reported; scope: Company-described claims intake and communication process. This does not establish claim outcomes, speed, or quality, and coverage remains subject to the policy.; verified: 2026-09-28.)

## What to Confirm in Quotes

Ask the CNA agent which underwriting company and coverage form they propose. Ask THREE for its named issuer and state-specific forms before comparing the two quotes. 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.
