## 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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [10](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Negotiation and Policy Wording

Lockton says its property team negotiates directly with underwriters and can tailor proprietary manuscript policy wording to a client's needs. Aon describes brokers working with carriers to build a program but does not state that it offers manuscript wording in this record. Ask both who negotiates terms and whether wording changes can be documented in the issued policy. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

### Exposure and Retention Analysis

Lockton lists retention analysis, exposure and value stratification, catastrophe modeling, and detailed reviews of policy terms and conditions. Aon describes catastrophe modeling, risk control, and its U.S.-available Property Risk Analyzer. Compare what data each team analyzes and whether its output recommends specific retentions or limits. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

### Complex Claim Preparation

Lockton describes assistance with complex claim recovery and detailed policy-wording review. Aon lists claims advocacy among its property services and also offers risk control and catastrophe analysis. Ask each broker to describe who leads claim preparation and what support is part of your engagement. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

| --- | --- | --- |
| 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..) | Lockton's property team negotiates commercial property placements directly with underwriters rather than through a centralized broking center, and says the same team that meets a client also negotiates with the market on their behalf.

| 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..) | Lockton says it can tailor its own proprietary manuscript property policy to a client's coverage needs, rather than only placing standard-form property policies. [7](https://global.lockton.com/us/en/products-services/property "Property Insurance") (Evidence: Company-reported; scope: Property product page as read 2026-09-23. The manuscript form's actual wording and how it compares to standard forms was not published on this page..) |
