## 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.

## What Is Gallagher?

Gallagher’s technology specialists serve startups through global enterprises, while its executive-risk team supports IPO and M&A needs; small firms seeking one simple digital quote should compare online agencies. [4](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance") [5](https://www.gallaghersmallbusiness.com/technology-services/ "Insurance for Technology & IT Businesses") [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") [7](https://www.gallaghersmallbusiness.com/legal-information/ "Legal Information") [8](https://www.ajg.com/merger-partners/woodruff-sawyer-is-now-gallagher/ "Woodruff Sawyer Is Now Gallagher")

[Gallagher profile](https://spot.insure/insurance-providers/gallagher)

## 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. [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [13](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Property and Damage Examples

Gallagher describes repair or replacement of buildings, equipment, and store fixtures after events such as fire, windstorm, or break-in. Aon describes property and contents protection from fire, natural catastrophe, theft, and vandalism, with possible business-interruption coverage. Ask Gallagher whether income protection is included and compare each policy's scheduled property and causes of loss. [9](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

### Risk Services

Aon describes catastrophe modeling, risk control, and its U.S.-available Property Risk Analyzer. Gallagher's small-business page focuses on coverage and adviser intake, while its larger property practice separately lists appraisal and global placement services. Ask whether Gallagher's appraisal services apply to your account and compare them with Aon's modeling scope. [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") [10](https://www.ajg.com/insurance/property-insurance/ "Property Insurance")

### Who Should Explore the Line

Gallagher recommends property coverage for businesses that own or rent premises, hold inventory, or rely on valuable tools and equipment; Aon describes service for organizations seeking to protect property and inventory without a published eligibility schedule. If a landlord owns the building, Gallagher notes that tenant property is not insured by that landlord's policy, so confirm both parties' schedules. [9](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

## What to Confirm in Commercial Property Insurance Quotes

- Does Gallagher’s quote cover tenant contents separately from a landlord’s building policy, and is business income included?
- Which Aon carrier, property values, and catastrophe modeling services apply to your schedule?

| Role in This Line | 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. [3](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..) | Gallagher Small Business arranges building and property insurance with partner carriers rather than underwriting it; its larger property practice separately brokers property programs with underwriters for bigger accounts.

| Who It’s For | 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. [3](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..) | Gallagher recommends this coverage for businesses that own or rent a building, store or office, own or rent expensive equipment or tools, hold inventory, or depend on other valuable business assets. [9](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") (Evidence: Company-reported; scope: Product page "Do you need Building and Property Coverage?" list; actual acceptance depends on underwriting..) |
| Coverage Features | 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. [3](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..) | Gallagher describes building and property coverage as paying to repair or replace stolen, lost or damaged business property, including the building, equipment and store fixtures, after events such as fire, windstorm or a break-in.

[9](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") (Evidence: Company-reported; scope: Product page context; specific lender or landlord requirements vary by lease and loan agreement..) |
| Limits and Retentions | 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. [3](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..) | The buildings-and-property product page does not publish limits, deductibles or premiums; it routes buyers to an advisor inquiry form instead.

| Risk Services | 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. [3](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..) | Gallagher's group-level property practice lists appraisal services and global program placement among its property offerings, though these are described at the practice level rather than tied to the small-business product page.
