It identifies differences and questions to confirm; it does not select a winner for a particular business.

## Summary

[3](https://www.aig.com/home/risk-solutions/business/casualty "Casualty Insurance - Business Casualty Risk Solutions | AIG US") [7](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. [1](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## 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. [5](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") [6](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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. [8](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [9](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [10](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [11](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Program design and brokerage

AIG describes customized structures using deductibles, self-insured retentions, captives, or retrospective programs for organizations that retain risk. Aon brokers workers’ compensation within a global construction practice serving contractors, owners, engineers, and other project participants. Ask AIG which retained-risk design may fit and Aon which carrier markets serve your project. [3](https://www.aig.com/home/risk-solutions/business/casualty "Casualty Insurance - Business Casualty Risk Solutions | AIG US") [7](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

### Project advice versus policy terms

Aon offers project risk advice to develop transfer, management, and mitigation strategies, but its reviewed page does not describe statutory benefits or a particular policy’s response. AIG lists workers’ compensation in corporate casualty and its nationwide motorsports program. Ask both for the issuing insurer, state forms, and the risk-advisory work included for your operation. [4](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance | AIG US") [7](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

## What to Confirm in Workers’ Compensation Insurance Quotes

- Ask Aon which carriers and state forms it can place for your construction workforce; ask AIG which program and risk-retention structure applies to your account. [3](https://www.aig.com/home/risk-solutions/business/casualty "Casualty Insurance - Business Casualty Risk Solutions | AIG US") [7](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample.

## Aon Reviews

Review Score: 6.1 / 10 from 3 rated sources, equally weighted.

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.
