## Research Scope and Use

Use this comparison to evaluate AIG and Aon for Commercial Property Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

AIG lists property insurance for organizations across sectors and a dedicated claims team. Aon describes broker-built property programs with business-interruption and catastrophe-risk services. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property 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. [4](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") [5](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## What Is Commercial Property Insurance?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [9](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Property insurer and claims team versus broker-built programs

AIG markets commercial property insurance for organizations including hospitals, universities, and manufacturers, and describes a dedicated Property claims team. Aon says its brokers work with insurers to build property programs for buildings, contents, and inventory, including potential business-interruption coverage after property damage. AIG’s page describes an insurance product; Aon’s describes brokerage and consulting. A buyer comparing them should identify the insurer and policy form behind any Aon placement, then compare it with the proposed AIG wording. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

### Engineering and risk-analysis support

AIG describes property risk engineers who collaborate with clients on mitigation. Aon lists catastrophe modeling, risk control, claims advocacy, and a U.S.-available Property Risk Analyzer for estimating potential losses and program options. These services can inform property values and risk planning, but do not themselves set policy limits or promise payment after a loss. Ask each provider how the service applies to your locations and whether its recommendations affect the quote or renewal. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

## What to Confirm in Commercial Property Insurance Quotes

- Ask AIG to identify the policy issuer and confirm how its engineering team supports your locations. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance")
- Ask Aon which insurer, business-interruption terms, catastrophe assumptions, and model outputs are reflected in a proposed placement. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

## Offering Details

| Criteria | AIG Commercial Property and Retail Property | Aon Commercial Property brokerage and risk-advisory offering |
| --- | --- | --- |
| Role in This Line | AIG markets commercial property insurance and identifies Retail Property as a product area. For domestic and global corporate and risk-management clients, the page describes both risk-transfer insurance and non-risk-transfer fronting or captive solutions; those structures are not the same as an insurance policy issued by AIG. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: AIG’s U.S. Commercial Property page. It does not identify the insurer or fronting company for a particular buyer’s placement..) | Aon describes property brokerage and consulting and says brokers work with insurance carriers to build a property program. Aon is marketing a brokered placement and risk-management service; the page does not name the insurer for an individual placement. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Company-reported; scope: Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance..) |
| Issuing Insurer | Confirm in your quote. | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Not found in reviewed sources; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available..) |
| Who It’s For | AIG names businesses including hospitals, universities and global manufacturing among the varied organizations for which it has property options. The page does not provide a complete eligible-class list or state-by-state availability schedule. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: Illustrative customer types on AIG’s U.S. Commercial Property page; examples do not establish an applicant’s eligibility..) | Aon describes property-risk services for organizations seeking to protect property, buildings, contents and inventory. Its page is a global capability description and does not define an applicant eligibility schedule. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Company-reported; scope: Audience stated by Aon on its global capability page; this does not establish a specific applicant’s eligibility or placement availability by U.S. state..) |
| Coverage Features | AIG describes commercial property insurance as protecting business physical property against unexpected events such as storm damage, theft and vandalism, and says coverage can extend to certain work-related contents such as office equipment, furniture, fixtures and inventory. These are examples; actual coverage depends on the facts and each policy’s terms, conditions and exclusions. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: General property description on AIG’s product page, not a summary of a specific policy or all covered causes of loss..) | Aon describes commercial property insurance as protection against loss of property, buildings and contents or inventory from perils such as fire, natural catastrophe, theft and vandalism; it says insurance can also provide business-interruption coverage after property damage. These are general descriptions, not terms of a buyer’s policy. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control..) |
| Limits and Retentions | The reviewed page does not state standard property limits, deductibles or retentions for a buyer. Confirm those amounts, covered causes and conditions in the quote and issued policy. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Not publicly disclosed; scope: AIG’s U.S. Commercial Property marketing page reviewed 2026-09-30; no buyer-specific quote or policy form was reviewed..) | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Not publicly disclosed; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed..) |
| Risk Services | AIG says property risk engineers help clients identify and mitigate loss and that its engineers collaborate with clients on solutions tailored to risk factors. The page does not state that these services are included for every account or guarantee reduced losses. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: Company-described commercial property risk engineering; account-specific service availability is not stated..) | Aon describes property brokerage and consulting for business interruption, captive integration, claims advocacy, catastrophe modeling, risk control and terrorism/crisis management. Its US-available Property Risk Analyzer models potential losses and insurance program options; tool availability does not establish placement availability. [6](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") (Evidence: Company-reported; scope: Company-reported brokerage and advisory services. Account-specific service terms are not stated..) |
| Claims Support | AIG describes a dedicated Property claims team and a claims promise intended to enable prompt resolution. The page does not publish a service-level deadline or claim outcome guarantee. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: AIG’s company-reported general property claims description; no account-specific claims handling terms were reviewed..) | Confirm in your quote. |

## 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.
