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.

## What Is General Liability Insurance?

General liability can protect your business when a customer or visitor claims you caused injury or damaged their property. It suits businesses serving customers or working on their premises; your own building, tools and stock need property coverage. [10](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://www.hiscox.com/documents/partner-agent/specimen_forms/GL_Form.pdf "Commercial General Liability Coverage Form")

## Key Differences in General Liability Insurance

### Brokered construction program and primary insurer appetite

Aon’s global construction practice describes broking and placement across construction insurance lines for contractors, owners, engineers, and other project participants. Berkshire Hathaway Specialty Insurance directly markets primary general liability, with contractor broad-form coverage, gradual-pollution features, and flexible limits. A buyer comparing these routes should distinguish Aon’s access to a placement from BHSI’s stated insurer product features, then identify the actual carrier in any Aon proposal. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [9](https://www.bhspecialty.com/us-products/us-casualty/ "Casualty")

### Target classes and available limits

BHSI’s casualty guide names commercial real estate, retail and grocery, financial institutions, construction, and energy as target classes and sets a $50,000 minimum premium per policy. Aon describes a broader range of construction participants and does not publish a GL premium floor or buyer limit. BHSI’s stated minimum can matter for smaller submissions; ask Aon for the actual market and premium needed for your risk. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [8](https://www.bhspecialty.com/wp-content/uploads/marketing/Casualty-Appetite-Guide-US.pdf "Casualty Appetite Guide - U.S.")

## What to Confirm in General Liability Insurance Quotes

- Ask Aon which carrier and contractor form it proposes, including pollution terms and limits. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [9](https://www.bhspecialty.com/us-products/us-casualty/ "Casualty")
- Ask BHSI whether your exact class meets appetite and whether the $50,000 minimum applies to the quoted policy. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [8](https://www.bhspecialty.com/wp-content/uploads/marketing/Casualty-Appetite-Guide-US.pdf "Casualty Appetite Guide - U.S.")

[3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Audience described for Aon’s global construction and infrastructure practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | The casualty guide lists primary GL forms and identifies commercial real estate, retail/grocery, financial institutions, construction and energy as target classes. [8](https://www.bhspecialty.com/wp-content/uploads/marketing/Casualty-Appetite-Guide-US.pdf "Casualty Appetite Guide - U.S.") (Evidence: Company-reported; scope: US casualty appetite guide dated 2026-07-15.

| Coverage Features | Aon lists General Liability within construction liability and describes casualty protection for third-party bodily injury or property damage associated with negligent acts during construction or operations.

[3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area.

Material limitation: Minimum premium is appetite guidance, not a quoted price or guaranteed minimum for all products..) |
| Risk Services | Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies. It also describes a global construction team and market access. These are company-reported brokerage and advisory services, not coverage benefits. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Confirm in your quote. |
