What Are the Key Differences Between AIG and Heffernan Insurance Brokers Professional Liability (E&O) Insurance?

Coverage Description and Placement

AIG describes a policy intended for claims alleging negligence in professional services, including third-party economic loss. Heffernan’s record describes the professional-liability coverage it brokers but leaves policy terms to the insurer selected for placement. Buyers can use AIG’s stated claim subject as a comparison point, then require Heffernan to identify the carrier, covered services and exclusions in its proposal. [1] [2]

Applying Through a Specialist

AIG markets entity-based specialty E&O that can be tailored to a service provider. Heffernan’s placement process is advisor-led, with application materials used to secure terms from insurers. That relationship can help present a complex risk, but the quote and policy determine the result. Send the same service description and contract examples to both routes for a fair comparison.
