Aon vs 
Gallagher: How Do They Compare for Commercial Auto Insurance?
What Is Aon?
Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. 1,2
What Is Gallagher?
Gallagher’s technology specialists serve startups through global enterprises, while its executive-risk team supports IPO and M&A needs; small firms seeking one simple digital quote should compare online agencies. 4,5,6,7,8
What Is Commercial Auto Insurance?
Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. 10,11,12,13
What Are the Key Differences Between Aon and Gallagher Commercial Auto Insurance?
Vehicles and Named Protections
Gallagher’s small-business page describes third-party bodily injury and property damage, uninsured or underinsured driver protection, physical damage to owned, hired, rented, or employee vehicles, and medical costs. Aon lists Automobile Liability within its professional-services offering. For a company mixing employee cars with owned vans, ask Gallagher how each class is scheduled and ask Aon which proposed policy terms address the same vehicles. 9 3
Starting the Application
Gallagher identifies an online quote form, an advisor phone line, and a callback request as ways to start. Aon describes Automobile Liability within its professional-services brokerage and advisory practice. A small business can compare those stated entry points while asking both providers which vehicles, drivers, and states can be submitted; an intake route alone does not establish a quote or effective coverage. 9 3

Aon vs Gallagher: Commercial Auto Insurance: documented features by provider
| Criteria | Aon Automobile Liability brokerage and risk-advisory offering | Gallagher Small Business Commercial Auto Insurance |
|---|---|---|
| Role in This Line | Aon presents Automobile Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. 3Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. | Gallagher Small Business arranges commercial auto coverage with partner carriers rather than underwriting the policy itself. 9Company-reported. Gallagher Small Business's direct-to-small-business commercial auto product page. |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. 3Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement. | The commercial auto product page does not name the insurer that would issue a given business's policy. 9Not publicly disclosed. Checked the commercial auto product page on 2026-09-23. |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. 3Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement. | Gallagher recommends this coverage for businesses that use vehicles for business purposes, including owned, hired and non-owned autos, rented or leased vehicles, and employees who drive their own cars for work. 9Company-reported. Product page "Recommended for businesses that" list; actual acceptance depends on underwriting. |
| Coverage Features | Aon lists Automobile Liability in its property-and-casualty offerings for professional services firms. The page does not describe covered autos, drivers, liability limits or policy terms. 3Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage. | Gallagher describes commercial auto as covering bodily injury and property damage to third parties, accidents caused by uninsured or underinsured drivers, physical damage to owned, rented, hired or employee vehicles, and medical costs for the business owner, employees and passengers, plus theft and damage. 9Company-reported. Product page coverage list; the issued policy and its exclusions control. Gallagher's small-business team says the commercial auto market remains challenging because of social inflation and the long-tail nature of auto liability claims, and that rising repair costs from added vehicle electronics and safety features, plus supply-chain delays, are increasing claim costs. 9Company-reported. Product page market-commentary section; a general market view, not a quote for any specific business. Gallagher illustrates the coverage gap when a personal vehicle is used for business: it describes a bakery owner whose personal auto insurer refused to pay a delivery-related accident claim because she lacked commercial auto insurance. 9Company-reported. Product page hypothetical claim scenario; illustrative example, not a report of an actual claim outcome. |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. 3Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | The commercial auto product page does not publish liability limits, deductibles or premiums; it directs prospective buyers to request a quote instead. 9Not publicly disclosed. Checked the commercial auto product page on 2026-09-23. |
| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. 3Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | Gallagher offers an online quote form, a small business advisor phone line (1-833-292-9441, Monday through Friday, 8 a.m. to 5 p.m., continental U.S.), and a scheduled callback request to start a commercial auto quote. 9Company-reported. Product page "Get Covered Now" section. |
