Aon vs 
Chubb: 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 Chubb?
Chubb fits technology firms seeking DigiTech ERM or small businesses with up to $30 million in revenue seeking a BOP; buyers wanting an instant direct purchase should compare online carriers. Agents can quote eligible small accounts, with a faster cyber route. 4,5,6
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. 9,10,11,12
What Are the Key Differences Between Aon and Chubb Commercial Auto Insurance?
Who Carries the Policy
Chubb says it underwrites commercial auto directly, either as a standalone policy or as an add-on to its small-business package. Aon’s page describes a global Professional Services Practice that helps arrange or advise on Automobile Liability; it does not identify the insurer for a client’s placement. A company wanting a direct underwriting submission can ask Chubb about its standalone route, while an Aon client should confirm which insurer and producing entity would appear on the quote. 7 8 3
Endorsements and Vehicle Terms
Chubb lists a broad-form endorsement with rented-auto and fellow-employee enhancements where allowed, plus a high-value-vehicle agreed-value endorsement. Aon’s reviewed description names Automobile Liability but gives no vehicle-level coverage or endorsement list. For leased vehicles, employee rentals, or high-value cars, ask which Chubb options are available in the state and ask Aon for the matching insurer forms and declarations. 7 3
