Aon vs Counterpart: General Liability Insurance

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

Aon construction advice and Counterpart’s professional-class channel

Aon describes a construction practice that places risk solutions and advises on project-specific transfer and mitigation. Counterpart’s GL appears through broker distribution alongside its Professional Liability product, aimed at professional classes. A contractor should ask Aon about project exposure; a professional-services firm should ask its broker how Counterpart’s paired placement fits both general and professional liability needs. [1] [4]

GL alone or accompanying professional liability

Aon characterizes GL around third-party injury or property damage connected with construction or operations. Counterpart frames GL as accompanying Professional Liability, with separate limits, rather than describing a standalone construction policy. That structure matters when a professional firm needs both premises and errors coverage: compare the two limits and ensure one policy’s terms do not leave a gap in the other. [1] [6]

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

Ask Aon which construction activities and contractual risks the proposed GL form addresses. [1] [4]
Ask the Counterpart broker whether GL is available without Professional Liability and how each coverage limit is scheduled. [1] [6]

Aon describes a construction practice that places risk solutions and advises on project-specific transfer and mitigation, while Counterpart’s GL appears through broker distribution alongside its Professional Liability product, aimed at professional classes.
