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

Broad construction brokerage and environmental-service package

Aon’s construction practice serves a wide project ecosystem, including contractors, owners, engineers, and developers, and places liability solutions across construction lines. Beazley’s published GL is narrower: it is part of BeazleyOne Environmental for engineering, consulting, project-management, remediation, and contracting firms that provide environmental services. A non-environmental construction company should treat Beazley’s described package as a specialized fit to test, not a general contractor offer. [1] [2]

Eligibility and occurrence wording

Aon describes casualty protection for third-party injury or property damage tied to negligent construction or operations but does not state a policy trigger. Beazley says its environmental package GL may be claims-made or occurrence, subject to eligibility. Ask Beazley which trigger applies to your quote and Aon to identify the form; the practice descriptions alone do not decide prior-acts or completed-operations treatment. [1] [2]

What Should You Confirm in Aon and Beazley General Liability Insurance Quotes?

  • Ask Beazley whether your specific environmental activities qualify and which trigger the quote uses. [1] [2]
  • Ask Aon for the proposed GL form, occurrence basis, and project-specific limits for the operations being insured. [1] [2]
