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. 1,2
What Is Harper Insurance?
Harper suits hard-to-place businesses such as contractors, care providers, manufacturers and transportation firms; standard small businesses seeking direct quotes should compare online carriers. Its workers’ compensation service helps classify payroll for audits. 4,5
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. 8,9,10
Key Differences in Commercial Property Insurance
Valuation Description
Harper summarizes commercial property as covering buildings, equipment, and inventory at replacement cost. Aon describes property insurance for buildings and contents but does not specify a valuation basis in its reviewed record. Ask both for the valuation method, coinsurance terms, and scheduled values; those details determine how a loss is adjusted. 6 3
Quote and Placement Route
Harper offers an online intake where a buyer selects property and supplies state, revenue, and business details; its form lists all 50 states and Washington, D.C. for quote requests. Aon describes brokers building programs with carriers and does not publish a comparable digital application. A request in either channel is not a guarantee of eligibility or binding. 6 3
Risk Analysis
Aon describes catastrophe modeling and its U.S.-available Property Risk Analyzer for potential loss and program options. Harper’s reviewed property claims describe replacement cost, its quote intake, and bundled equipment breakdown for manufacturers, not catastrophe modeling. If modeling informs your decision, ask Harper what property analysis is included and Aon what data it needs. 3 7
What to Confirm in Commercial Property Insurance Quotes
- For Harper, does the quote use replacement cost for every property class, and can equipment breakdown be included?
- For Aon, which locations and catastrophe scenarios will be modeled, and what carrier terms result?

Aon vs Harper: Commercial Property Insurance: documented features by provider
| Criteria | Aon Commercial Property brokerage and risk-advisory offering | Harper Commercial Property Insurance |
|---|---|---|
| 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. 3Company-reported. Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance. | For commercial property, Harper describes calling the insurance companies that write the coverage and presenting the customer with the resulting options to choose from, rather than issuing a commercial property policy itself. 6Company-reported. Homepage 'What we cover' introduction and coverage list, where commercial property is one of the enumerated lines. |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. 3Not found in reviewed sources. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available. | Harper's public pages do not name the insurer or insurers that would underwrite a commercial property policy; the homepage shows an unlabeled panel of insurer logos it says it works with, describing the rest as 'specialists who cover the work the big names turn down.' 6Not publicly disclosed. Checked the homepage insurer-logo panel on 2026-09-23; no carrier names accompany the logos in the page text. |
| 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. 3Company-reported. 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. | Harper's quote-intake form lists all 50 states and Washington, D.C. as selectable, indicating it takes commercial property quote requests nationwide, though eligibility for a specific building or business depends on underwriting review not described on the page. 6Company-reported. Homepage quote-intake state selector. |
| 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. 3Company-reported. 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. | Harper's homepage summarizes commercial property insurance as covering a business's buildings, equipment and inventory at what it costs to replace them. 6Company-reported. Homepage 'What we cover' blurb; the issued policy and declarations would control actual valuation method and terms. On its manufacturing industry page, Harper bundles property coverage with equipment breakdown, describing it as covering the building, the production line and machinery that cannot be down for a week. 7Company-reported. Manufacturing industry page; this is a manufacturer-specific bundle of property and equipment breakdown, not necessarily how Harper packages commercial property for other industries. |
| 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. 3Not publicly disclosed. Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed. | The reviewed pages do not publish commercial property limits, deductibles or valuation methods such as replacement cost versus actual cash value; those terms are not shown until a specific quote is issued. 6,7Not publicly disclosed. Checked the homepage and manufacturing industry page on 2026-09-23. |
| 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. 3Company-reported. Company-reported brokerage and advisory services. Account-specific service terms are not stated. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | You can start a commercial property quote through Harper's online intake by selecting the 'My building, equipment, and inventory (property)' checkbox alongside the business's state, estimated annual revenue and a description of what it does. 6Company-reported. Homepage quote-intake form. |
