## Summary

AIG lists broad corporate property customers and risk engineers. Lockton describes direct underwriter negotiation, manuscript policy capability, and detailed coverage and retention analysis. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [7](https://global.lockton.com/us/en/products-services/property "Property Insurance")

## 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 Lockton?

Lockton suits technology companies and larger businesses seeking a broker across cyber, D&O, property, liability and benefits; small firms wanting an instant standard quote should compare digital agencies. [4](https://global.lockton.com/us/en "Lockton United States") [5](https://global.lockton.com/us/en/technology "Technology") [6](https://global.lockton.com/us/en/terms-of-business "US Terms of Business")

## 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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [10](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Property underwriting and negotiated policy wording

AIG markets property insurance to organizations including hospitals, universities, and manufacturers, with property engineers supporting loss mitigation. Lockton says its property team negotiates directly with underwriters and can tailor a proprietary manuscript policy to a client’s coverage needs. For complex risks, customized language may address exposures that a standard form leaves unclear; ask which provisions Lockton can negotiate and compare them with the issued AIG form. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [7](https://global.lockton.com/us/en/products-services/property "Property Insurance")

### Exposure analysis and account services

AIG describes engineering collaboration and a dedicated property claims team. Lockton lists policy-wording review, retention analysis for deductible selection, exposure and value stratification, catastrophe modeling, underwriting specifications, and complex-claim assistance. Buyers should distinguish services before placement from claims support after a loss, and confirm which are provided for the particular account. Neither service list substitutes for comparing covered causes, limits, valuation, and catastrophe terms. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [7](https://global.lockton.com/us/en/products-services/property "Property Insurance")

## What to Confirm in Commercial Property Insurance Quotes

- Ask AIG which engineering, claims, and property forms are included for your account. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance")
- Ask Lockton what wording changes and retention analysis it will pursue, and which insurer will issue the policy. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance")

## Offering Details

| Criteria | AIG Commercial Property and Retail Property | Lockton Property Insurance Brokerage |
| --- | --- | --- |
| 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..) | Lockton's property team negotiates commercial property placements directly with underwriters rather than through a centralized broking center, and says the same team that meets a client also negotiates with the market on their behalf. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") (Evidence: Company-reported; scope: Property product page as read 2026-09-23..) |
| Issuing Insurer | Confirm in your quote. | The property page does not name the insurers Lockton places commercial property coverage with; it describes relationships across the global marketplace in general terms only. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") (Evidence: Not publicly disclosed; scope: Property product page checked 2026-09-23..) |
| 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..) | Confirm in your quote. |
| 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..) | Lockton says it can tailor its own proprietary manuscript property policy to a client's coverage needs, rather than only placing standard-form property policies. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") (Evidence: Company-reported; scope: Property product page as read 2026-09-23. The manuscript form's actual wording and how it compares to standard forms was not published on this page..) |
| 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..) | Confirm in your quote. |
| 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..) | Lockton lists specific property services: detailed review of coverage terms, conditions and policy wordings; retention analysis for deductible selection; exposure and stratification-of-value analysis; catastrophic modeling; preparation of underwriting specifications; and assistance with complex claim recovery. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") (Evidence: Company-reported; scope: Property product page as read 2026-09-23. These are described capabilities, not a guarantee of outcome on any specific account..) |
| 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. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

- Trustpilot: Trustpilot TrustScore 1.9 (out of 5); 252 reviews.
