What Are the Key Differences Between Aon and THREE by Berkshire Hathaway General Liability Insurance?

Aon’s construction placements and THREE by Berkshire Hathaway’s bundled GL

Aon’s construction practice is aimed at contractors, owners, engineers, architects, and other project participants. THREE by Berkshire Hathaway lists GL as part of its combined Business Owners Policy rather than as a standalone public product. A construction buyer should compare the project placement Aon can arrange with the small-business package route THREE by Berkshire Hathaway describes and verify that GL appears in the actual quote. [1] [2]

Project fit and actual package selections

Aon describes casualty protection for construction operations, while THREE by Berkshire Hathaway’s product page markets GL within its package without separate line terms. The page does not establish whether GL appears in every quote or how a claim responds. That makes the declarations and coverage schedule especially important: do not treat the package category list as a promise of a specific limit or coverage grant. [1] [2]

  • Ask Aon which insurer, construction form, and limits are proposed. [1] [2]
  • Ask THREE by Berkshire Hathaway to identify the GL coverage, limits, deductibles, and issuer in the quote-specific insurance summary. [1] [2]
