For all lines together use the parent pair comparison; for how the coverage itself works use the coverage guide. **Questions this page answers:** - AIG vs WTW for Commercial Property Insurance: how do they differ? - Which is better for Commercial Property Insurance, AIG or WTW? - What does AIG or WTW publish about Commercial Property Insurance (limits, eligibility, claims, add-ons)? - What should I confirm in a quote for Commercial Property Insurance from AIG or WTW? **Key facts:** - Line: Commercial Property Insurance. Providers: AIG and WTW. - Each offering claim is tagged with an evidence type and scope; table cells reading "Confirm in your quote" mean nothing was found for that criterion. - Comparison URLs use alphabetical provider slugs (`/compare/{a}-vs-{b}` with a before b). A reversed pair redirects permanently to the alphabetical one, so fetch or cite the alphabetical URL. **Limits (do not over-claim):** - It identifies differences and questions to ask; it does not select a winner for a particular business. - "Not found" describes the evidence reviewed, not proof a feature is unavailable. - Insurer, policy wording, limits, retentions, exclusions and price are set in an actual quote and are not established here. **Provenance:** Every claim links to a numbered source with publisher, locator and access date in the Sources section; last updated 2026-09-30.

AIG describes property insurance for broad audiences; WTW documents programs for residential real estate and data centers. ## Research Scope and Use Use this comparison to evaluate AIG and WTW 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 names hospitals, universities, and manufacturers among property customers. WTW describes property placements for residential real estate and an integrated data-center solution.

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 WTW? WTW is an insurance broker whose documented services include manufacturing risk-program design and specialist property and cargo programs. Its marketed property scope includes residential real-estate stakeholders and a separate integrated data-center program; other named capabilities vary in date and geography.

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.

AIG markets commercial property insurance for organizations across several industries. WTW’s cited materials identify property programs for residential real-estate stakeholders and an integrated solution for data-center construction and operations. A specialized data-center buyer should ask how the WTW solution coordinates property exposures across construction and operating phases; AIG’s public description is broader and does not specify that same program structure. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [5](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector") ### AIG names hospitals, universities, and manufacturers among property customers. WTW describes property placements for residential real estate and an integrated data-center solution. Binding and document review [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") ## What to Confirm in Commercial Property Insurance Quotes - AIG describes property risk engineers and a dedicated claims team. WTW’s North American terms say an insurer’s quote is not confirmation of coverage; after a client orders binding, WTW seeks a formal commitment, typically a binder, and reviews policies and endorsements against negotiated terms. Buyers need to track that step before assuming coverage is bound and should compare the final binder against the requested property protections. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") - Ask AIG for account-level engineering access and the insurer’s binding confirmation. [5](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector") ## Offering Details | Criteria | AIG Commercial Property and Retail Property | WTW Commercial Property 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..) | Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Terms for applicable North American Corporate Risk & Broking engagements. WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement..) | | Issuing Insurer | Confirm in your quote. | The reviewed WTW sources do not identify an issuing insurer for a specific commercial property placement.

Confirm the carrier on the quote and issued policy..) | | 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..) | WTW describes property placements for residential real-estate stakeholders and an integrated property solution for data-center construction and operations. [5](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW") (Evidence: Company-reported; scope: These are separately scoped industry solutions. They do not establish terms or eligibility for every commercial-property placement..) | | 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 sources do not state a buyer-specific commercial property limit, retention, or deductible.

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..) | WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Broker document-review process under the cited terms, when WTW handles this line's placement. It does not certify that a policy covers a claim or replace the issued wording..) | | How to Apply | Confirm in your quote. | WTW's North American terms say an insurer quote is not confirmation of coverage; if the client orders binding, WTW seeks a formal insurer commitment, typically a binder. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Applies to placements governed by the cited North American Corporate Risk & Broking terms. It does not establish a self-service quote route or promise coverage availability for this line..) | | 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.

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.
