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 Workers’ Compensation Insurance?
Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. 8,9,10,11
Key Differences in Workers’ Compensation Insurance
Construction account or small-business product
Aon describes workers’ comp within a global construction practice serving contractors, owners and engineers. Chubb directly underwrites the line for small businesses with one employee through $30 million in revenue, including technology classes. Construction buyers should check whether their revenue and class fit Chubb’s stated range. 3 7
Claims services and policy pairing
Chubb says the policy can pair with a Chubb BOP and describes nurse case managers, return-to-work support, pharmacy management and preferred-provider access. Aon describes project risk advice but no workers’ comp medical or claim services. Ask which Chubb services apply to the account and whether the policy can be paired. 3 7
Quote access and limits
Chubb accepts online quote requests or applications through appointed agents and brokers; it describes varied employer-liability limits without specific figures. Aon describes broking but no application flow or limits. Request the proposed limits and carrier details. 3 7
