Chubb vs

What Is Chubb?

Key Differences in Commercial Property Insurance
Who Carries the Risk
Chubb underwrites commercial property itself. 4 Marsh McLennan Agency (MMA), Marsh's middle-market subsidiary, places the coverage as a broker; Marsh's separate technology practice arranges property coverage for digital infrastructure such as data centers. 10
How Coverage Is Presented
Chubb describes its property offering as full-limit package or monoline, primary, quota-share and excess all-risk coverage across three program tiers, without naming individual perils. 4 MMA instead names flood, hurricane and windstorm, wildfire and earthquake as distinct coverage subsections alongside general physical-asset protection. 10 For data centers specifically, Marsh says property is typically paired with equipment breakdown, business interruption, cyber and general liability coverage. 11
Services Attached to the Placement
Chubb ties Chubb Risk Consulting and a dedicated property-claims process to its policies. 4 MMA lists hazard assessment and valuation services, loss and catastrophe modeling, claims advocacy, and alternative risk solutions such as captives and parametric insurance. 10
What to Confirm in Commercial Property Insurance Quotes
- Ask which entity issues the policy: Chubb underwrites its own program, while neither MMA page names an insurer. 4 10
- If you operate a data center, ask MMA whether property is quoted alongside equipment breakdown, cyber and general liability or as a standalone line. 11
- Request published limits and deductibles from both; neither page discloses them. 4 10
- Ask MMA which named perils, such as earthquake or wildfire, are included by default versus quoted separately. 10
