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

Construction placement compared with Chubb package choices

Chubb’s public offer places GL inside BOP, Benchmarq, or Customarq packages, or combines it with pollution cover through GL Plus. A buyer seeking a construction placement should ask Aon which insurer fits the project; a Chubb buyer should first identify which package or GL Plus structure is being quoted. [1] [3]

When pollution coverage enters the GL discussion

Aon describes construction casualty protection for third-party bodily injury or property damage tied to negligent acts, without publishing policy wording. Chubb GL Plus adds affirmative products pollution and scalable premises pollution liability to GL, with umbrella pairing available. If pollution is a material site or product exposure, ask Chubb to show those components and ask Aon whether its proposed form addresses the same exposure. [1] [4]

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

  • Have Aon identify the carrier, construction operations insured, and any pollution coverage in the proposal. [1] [3]
  • Ask Chubb whether GL Plus or a commercial package is quoted and request the pollution limits and exclusions. [1] [4]
