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

A construction placement practice alongside Relm’s GL market

Aon serves a broad construction audience, including contractors, owners, architects, engineers, and developers. Relm’s GL record identifies its own eligibility and coverage boundaries. A buyer with unusual or project-heavy operations should ask Relm whether those operations fit, while asking Aon which markets it can approach for the account. [1] [5]

Project advice and stated policy boundaries

Aon describes project advice on risk transfer and mitigation but leaves policy terms to the insurer. Relm’s offering describes GL coverage and exclusions, which buyers should review against their actual work. This is not an apples-to-apples comparison of policy breadth until Aon identifies the proposed form; use Relm’s published boundaries as questions for both quotes. [1] [5]

  • Ask Aon for the policy form, insurer, and construction exclusions in its proposal. [1] [5]
