## 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. [13](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [14](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [15](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## What Are the Key Differences Between Marsh and WTW Commercial Property Insurance?

### Data-center coverage around the building

Marsh says data-center property is typically paired with equipment breakdown, business interruption, cyber, and general liability because a conventional property policy alone can leave gaps. WTW separately describes an integrated property solution for data-center construction and operations, without listing those companion lines in the reviewed claim. For a facility, compare which policies are coordinated and where physical damage, equipment failure, and interruption meet. [6](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services") [8](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector")

### Risk services and placement

Marsh McLennan Agency describes hazard assessment, valuation, loss and catastrophe modeling, claims advocacy, risk control, and alternative risk options for property clients. WTW’s record names a data-center placement solution and says its team reviews policy documents against negotiated terms. Ask Marsh what assessments apply to your facility and ask WTW to identify its placement and document-review responsibilities. [5](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [12](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [8](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector")

- Which equipment-breakdown, cyber, and business-interruption sections will Marsh coordinate with the property policy, and what dependencies apply? [6](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")
- What does WTW’s data-center solution include during construction versus operations, and which markets issue each policy? [8](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector")

It does not certify that a policy covers a claim or replace the issued wording..) |
| How to Apply | You work with an MMA property specialist directly; the page names a National Accounts Property Practice Leader and describes advisor-led placement rather than an online quote. [5](https://www.marshmma.com/us/solutions/property.html "Property Insurance") (Evidence: Company-reported; scope: MMA property insurance page..) | 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.
