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 Umbrella and Excess Liability Insurance?
Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. 8,9,10,11,12
Key Differences in Umbrella and Excess Liability Insurance
Construction Placement and Small Business Focus
Aon places umbrella and excess within a global construction practice serving project participants across organizations of varied size and complexity. TechInsurance describes umbrella as especially relevant where a business must carry more than $2 million or faces high liability risk, such as a storefront. A construction buyer should ask whether its project account fits TechInsurance’s stated small-business framing or Aon’s construction practice. 3 7
Multiple Policies or One Policy
TechInsurance says umbrella can extend liability over general liability, employer liability and commercial auto, while excess generally raises the limit on one policy. Aon lists umbrella and excess separately but does not describe the attachment structure for a specific account. Ask each route to map coverage to the same underlying schedule. 3 7
Active Underlying Coverage
TechInsurance says umbrella requires an active underlying policy. Aon’s practice page lists coverage areas without an account-specific underlying policy requirement. A buyer with multiple project policies should confirm which lines must remain active and how each one is scheduled. 3 7
