# Gallagher vs Marsh Commercial Property Insurance

Gallagher and Marsh McLennan Agency both split commercial property into a general small-business tier and a specialized practice for larger or technical risk.

## Research Scope and Use

Use this comparison to evaluate Gallagher and Marsh 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

Gallagher's small-business site arranges building and property coverage through partner carriers, while its group-level practice separately offers appraisal and global placement services. Marsh McLennan Agency places property for middle-market clients, and Marsh runs a separate technology-industry practice that bundles property with equipment breakdown, business interruption and cyber for data centers.

## What Is Commercial Property Insurance?

Commercial property insurance addresses physical business assets, including buildings, equipment, furniture and inventory, subject to the policy’s covered property, causes and terms. [14](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)")

## Key Differences in Commercial Property Insurance

### How Each Firm Segments the Product

Gallagher Small Business's product page arranges building and property coverage with partner carriers for owners renting or holding a building, store or office, while a separate group-level Gallagher practice brokers property programs directly with underwriters for larger accounts. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [7](https://www.ajg.com/insurance/property-insurance/ "Property Insurance") Marsh splits along a similar line but by industry rather than account size: Marsh McLennan Agency (MMA) places property for middle-market clients generally, and Marsh's technology-industry practice separately structures coverage for digital infrastructure such as data centers. [12](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [13](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")

### What the Base Coverage Bundles

Gallagher's small-business description covers repair or replacement of stolen, lost or damaged property, including the building, equipment and fixtures, after events like fire, windstorm or a break-in. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") For data centers specifically, Marsh says property coverage is typically paired with equipment breakdown, business interruption, cyber and general liability to close gaps a standalone property policy would leave open:

For data centers specifically, Marsh says property coverage is typically paired with equipment breakdown, business interruption, cyber and general liability coverage to close gaps that a conventional property policy alone would leave open. [13](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services") (Evidence: Company-reported; scope: Data center insurance page FAQ..)

### Property-Specific Services

Gallagher's group-level property practice lists appraisal services and global program placement among its offerings, though these are described at the practice level rather than confirmed for the small-business tier. [7](https://www.ajg.com/insurance/property-insurance/ "Property Insurance") MMA's property practice names hazard assessment and valuation, loss and catastrophe modeling, claims advocacy, and alternative risk solutions such as captives and parametric insurance. [12](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What to Confirm in Commercial Property Insurance Quotes

- Ask which Gallagher or Marsh entity would actually place your account, since both split their offering by account size or industry. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [12](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- Neither company names an issuing insurer on its property pages; ask for the carrier before comparing terms. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [12](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- If you run a data center or similar infrastructure, ask Marsh whether the bundled equipment breakdown, cyber and general liability components are priced together or separately. [13](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")
- Ask Gallagher whether appraisal and global placement services apply to your account size or are reserved for the larger property practice. [7](https://www.ajg.com/insurance/property-insurance/ "Property Insurance")
- Get published limits and deductibles from both; neither page discloses them upfront. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [12](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
