## Summary

Aon places general liability through its construction practice, which works across projects and uses a global network, while Liberty Mutual lists GL risk services alongside a marketed general-liability product. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability")

## 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. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

## What Is Liberty Mutual Business Insurance?

Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms.

## 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. [7](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://www.hiscox.com/documents/partner-agent/specimen_forms/GL_Form.pdf "Commercial General Liability Coverage Form")

## Key Differences in General Liability Insurance

### Construction placement or Liberty Mutual’s GL services

Aon places general liability through its construction practice, which works across projects and uses a global network. Liberty Mutual lists GL risk services alongside a marketed general-liability product. For a contractor, the practical question is whether those services address project-specific exposures or the buyer needs a broader construction-market placement; neither provider’s description establishes a particular carrier or account terms. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability")

### Coverage description and quote specifics

Aon describes casualty protection for third-party bodily injury or property damage tied to negligent construction or operations. Liberty Mutual’s reviewed page describes GL coverage and its target businesses but does not publish policy limits or full terms. A construction firm should compare the actual quote forms for covered operations, aggregates, and contractual requirements rather than infer those details from either overview. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability")

## What to Confirm in General Liability Insurance Quotes

- Ask Aon which insurer, construction form, and project limits it proposes. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability")
- Ask Liberty Mutual to state available limits and exclusions for your class and named operations. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://business.libertymutual.com/commercial-solutions/general-liability/ "General liability")
