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.

Key Differences in Commercial Auto Insurance

Different Placement Audiences

Aon places Automobile Liability within a practice aimed at law, accounting, and consulting firms. Zurich's reviewed auto offering is specifically for rental fleets and describes fleet-size, vehicle, and rental-use information in its application. A professional-services company should verify that Zurich's rental-fleet scope applies before comparing it with Aon's broader brokerage listing. 3 6

Liability and Vehicle Damage

Zurich identifies state financial-responsibility liability and uninsured/underinsured motorist and no-fault personal-injury options for rental fleets, plus specified-peril, comprehensive, and collision physical damage. Aon only lists Automobile Liability and does not provide these details in its record; ask Aon for its proposed forms and scheduled vehicle protection. 6 3

Zurich’s Catastrophic Option

Zurich says its catastrophic physical-damage option requires an occurrence involving at least two insured autos and excludes collision, overturn, and conversion. Aon's record does not describe an equivalent auto option, so ask whether its proposal covers fleet-wide events and how each policy treats a single-vehicle loss. 6 3

What to Confirm in Commercial Auto Insurance Quotes

  • Does Zurich’s rental-fleet program fit your vehicle use, and how does its two-auto catastrophic trigger apply?
  • Which vehicle physical-damage options, exclusions, limits, and insurer will Aon arrange?

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

The available Zurich review evidence is mixed and comes from distinct populations: a car-rental-business editorial rating, broad global and U.S. review-platform snapshots, and a BBB business-profile grade. These are not a representative measure of every Zurich commercial policy or claim.[1][4][5][6][7]
