## What Is Workers’ Compensation Insurance?

Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. [10](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [11](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [12](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [13](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Construction Practice and Workers’ Comp Services

Aon describes a global construction practice for contractors, owners, engineers and project participants. Heffernan Insurance Brokers places workers’ comp across small-business, healthcare, home-care and transportation practices. The published audiences differ: project-focused construction advice versus multiple operating-sector practices. [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")

### Claims Advocacy and Medical Triage

Heffernan Insurance Brokers describes customized claims strategy, direct carrier liaison, experience-mod analysis and 24/7 telephonic or onsite medical triage. Aon’s reviewed page describes project risk advice but not workers’ comp claim services. An employer should ask which of these services are included and who coordinates with the insurer. [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")

### Carrier and Workforce Scope

Heffernan Insurance Brokers says it does not underwrite policies and does not identify the carrier for an account. Aon likewise describes broking without a named insurer. Confirm the issuing company and service responsibilities in either proposal. [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 Workers’ Compensation Insurance Quotes

- Ask Heffernan Insurance Brokers whether triage and claims advocacy apply to the proposed policy and what they cost. [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")
- Ask Aon for the carrier and claim contact model for the construction account. [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")

## Offering Details

| Criteria | Aon Workers’ Compensation brokerage and risk-advisory offering | Heffernan Workers' Compensation Brokerage and Claims Advocacy |
| --- | --- | --- |
| 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 workers’ compensation, 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 workers' compensation among the basic coverages it places for business clients, and runs a separate claims-consulting division that works alongside the issuing carrier rather than underwriting the policy itself. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [9](https://www.heffins.com/business-insurance/claims-advocacy/ "Claims Advocacy") (Evidence: Company-reported; scope: Business Insurance Brokerage and Claims Advocacy pages 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..) | The reviewed pages do not name a specific insurer for Heffernan-placed workers' compensation policies; the healthcare and transportation practice pages instead describe relationships with 'the nation's top' or 'top transportation' carriers generically. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [8](https://www.heffins.com/business-insurance/health-care/homecare/ "Home Care Business Insurance") (Evidence: Not publicly disclosed; scope: Business Insurance Brokerage, Small Business, and Home Care pages 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 places workers' compensation for businesses of all sizes across its small-business, healthcare, home care, and transportation practices, among others. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [8](https://www.heffins.com/business-insurance/health-care/homecare/ "Home Care Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance and Home Care Business Insurance pages as read on 2026-09-23; not an exhaustive eligibility schedule..) |
| Coverage Features | Aon lists Workers’ Compensation Insurance among the construction coverage areas it brokers. The page does not describe state-specific statutory benefits, employer-liability terms or how a buyer’s policy responds. [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 workers' compensation as covering injuries to employees while on the job, and says the cost has the greatest financial impact on a home care agency's expenses among the coverages in that package. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [8](https://www.heffins.com/business-insurance/health-care/homecare/ "Home Care Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance and Home Care Business Insurance pages as read on 2026-09-23; the reviewed pages do not describe statutory limits or state-specific benefit schedules..) |
| 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..) | The reviewed pages do not publish premium ranges or experience-modification benchmarks for workers' compensation. [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 Brokerage, Small Business, and Home Care 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..) | Heffernan's Claims Advocacy division offers workers'-compensation-specific services including a customized claims strategy, direct carrier liaison, experience-mod analysis to identify cost-reduction opportunities, and 24/7 telephonic or onsite medical triage with telemedicine options. [9](https://www.heffins.com/business-insurance/claims-advocacy/ "Claims Advocacy") [8](https://www.heffins.com/business-insurance/health-care/homecare/ "Home Care Business Insurance") (Evidence: Company-reported; scope: Claims Advocacy page as read on 2026-09-23; separately, home care insurance specialists are described as advising on workers'-comp coverage and premium for that program..) |
| Claims Support | Confirm in your quote. | Heffernan says its claims consulting division has more than 25 years of experience, has managed over $1 billion in claims, and reduces claim processing time by up to 75% through its proactive and telephonic-triage approach; these are company-reported performance figures, not independently verified. [9](https://www.heffins.com/business-insurance/claims-advocacy/ "Claims Advocacy") (Evidence: Company-reported; scope: Claims Advocacy page as read on 2026-09-23; figures are Heffernan's own marketing statistics, described here as company-reported rather than adopted as verified performance..) |
