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 Gallagher?
Gallagher’s technology specialists serve startups through global enterprises, while its executive-risk team supports IPO and M&A needs; small firms seeking one simple digital quote should compare online agencies. 4,5,6,7,8
What Is General Liability Insurance?
General liability can protect your business when a customer or visitor claims you caused injury or damaged their property. It suits businesses serving customers or working on their premises; your own building, tools and stock need property coverage. 10,11,12
Key Differences in General Liability Insurance
Construction placements and Gallagher’s small-business policy
Aon’s practice names construction contractors, owners, developers, engineers, architects, and project financiers as clients. Gallagher’s reviewed product is specifically its Small Business General Liability Insurance. A larger or project-driven construction buyer should ask Gallagher whether the small-business form fits its exposures, while Aon buyers should get the proposed market and policy form rather than rely on the practice description. 3 9
Who the published coverage is for
Aon describes casualty protection for third-party injury or property damage connected to negligent construction or operations. Gallagher describes GL as protection against third-party injury and property-damage claims, with covered expenses set by the policy. Those high-level descriptions overlap, but do not establish matching definitions, limits, or exclusions; compare the forms for completed work and contractual liability. 3 9
