## Summary

Aon’s construction practice serves contractors, developers, owners, engineers, architects, and investors, while Heffernan’s GL page describes its eligible buyers and offers standard and on-demand brokerage roles. [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://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

## 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. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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. [9](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://www.hiscox.com/documents/partner-agent/specimen_forms/GL_Form.pdf "Commercial General Liability Coverage Form")

## Key Differences in General Liability Insurance

### Project market focus alongside Heffernan’s GL audience

Aon’s construction practice serves contractors, developers, owners, engineers, architects, and investors. Heffernan’s GL page describes its eligible buyers and offers standard and on-demand brokerage roles. The distinction can affect where a submission goes: construction participants can ask Aon about project markets, while Heffernan buyers should confirm which service model applies to their account. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### Placement roles and insured operations

Aon describes GL in the context of casualty protection for construction operations; its practice page does not establish the buyer’s exact policy form. Heffernan distinguishes its standard and on-demand brokerage roles, but the reviewed line summary does not resolve each carrier or limit for an individual buyer. Ask both to connect the proposed coverage to your actual operations and contracts. [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://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

## What to Confirm in General Liability Insurance Quotes

- Ask Aon for the insurer, form, and any project-specific endorsements. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Ask Heffernan which brokerage role applies, who issues the policy, and what limit is available.

## Offering Details

| Criteria | Aon General Liability brokerage and risk-advisory offering | Heffernan General Liability Insurance |
| --- | --- | --- |
| Role in This Line | Aon says its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For general liability, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. [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 global construction and infrastructure practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | Heffernan lists general liability among the basic coverages it places for business clients through its standard commercial-insurance brokerage, shopping insurers rather than underwriting the policy itself. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") (Evidence: Company-reported; scope: Business Insurance Brokerage page as read on 2026-09-23..)<br><br>Separately, Heffernan has partnered with Thimble Insurance Services to distribute an on-demand general liability product bought directly online, a distinct and narrower distribution model from its standard commercial brokerage placement. [8](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23..) |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | For the Thimble-partnered on-demand product, Heffernan says policies are underwritten by A-rated insurers, naming Markel Insurance Company. The reviewed pages for Heffernan's standard commercial general liability placements do not name an insurer. [8](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Short-Term General Liability page for the named insurer; Business Insurance and Small Business pages for the standard-placement gap, as read on 2026-09-23..) |
| Who It’s For | Aon describes its global construction and infrastructure practice as serving contractors, owners, developers, engineers, architects, designers, financiers and investors, and says it works with organizations of varied sizes and complexity. [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..) | Heffernan's small-business division says it serves sole proprietors through fast-growing companies across industries including construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, plus named specialty programs. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; no minimum size or exclusion was published..) |
| 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. A policy’s actual insureds, triggers, exclusions and conditions are not stated on this practice page. [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. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | Heffernan describes general liability as covering bodily injury and property damage caused by a company, whether by its people or its products. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; the reviewed pages do not list specific exclusions or endorsements..) |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | Heffernan's Thimble-partnered on-demand product advertises $1 million or $2 million general liability limits, with pricing starting at $5 for short terms. [8](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23; Thimble's own disclaimer says eligibility, pricing, and coverage vary by state, activity class, and other factors..)<br><br>For its standard commercial general liability placements, Heffernan's reviewed pages do not publish limit, retention, or premium ranges. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Not publicly disclosed; scope: Business Insurance and Small Business Insurance pages as read on 2026-09-23..) |
| 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..) | For standard commercial clients, Heffernan says it provides claims services, loss control, HR consulting, and risk-management and assessment services alongside placed coverages such as general liability. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") (Evidence: Company-reported; scope: Business Insurance Brokerage page as read on 2026-09-23; not general liability-specific and not described for the Thimble-partnered on-demand product..) |
| How to Apply | Confirm in your quote. | The Thimble-partnered product is bought directly online with no paper forms, producing an ACORD certificate of insurance in under 30 seconds according to Heffernan's page. [8](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23..) |
