What Are the Key Differences Between Aon and Nationwide General Liability Insurance?

Project placements and Nationwide’s listed GL buyers

Aon’s construction practice serves contractors, owners, developers, engineers, and architects. Nationwide’s GL overview names its own target classes. A construction buyer should check both class fit and project requirements instead of reading either practice description as a promise of eligibility; Aon’s material is specifically organized around construction placement. [1] [5]

Advisory work and policy details

Aon describes project-specific risk advice to develop transfer and mitigation strategies. Nationwide’s GL overview addresses coverage and buying details, not the same advisory scope. Ask Nationwide for the policy language that applies to your contracts and ask Aon which advisory work is included, then compare the concrete deliverables and policy terms separately. [1] [5]

  • Ask Aon which markets and project risk services apply to your construction submission. [1] [5]
  • Ask Nationwide to confirm your class, form, and contractual-liability terms in writing. [1] [5]
