Key Differences in Commercial Property Insurance
Coverage and Valuation
Gallagher’s small-business property page describes repairing or replacing buildings, equipment, and store fixtures after fire, windstorm, or a break-in. MMA says it tailors property placement to an organization’s industry and risks but does not publish specific peril terms. A tenant or owner should compare the scheduled building and contents against the causes of loss shown in the proposed policy. 6 10
Placement and Buyer Service
Gallagher’s intake asks about the company, business description, additional coverage interests, employee count, and revenue; it also names appraisal and global placement services in its larger property practice. MMA asks buyers to contact an adviser or specialist, without a published quote checklist. Ask whether the property values will be appraised or modeled for replacement cost. 6 10
What to Confirm in Commercial Property Insurance Quotes
- Ask Gallagher whether the quote includes tenant contents, inventory, and the building or only the insured party’s property. 6
- Ask MMA for the proposed peril list, appraisal basis, and any separate flood or catastrophe terms. 10
- Ask both to identify the insurer, scheduled locations, valuation basis, limits, deductibles, and exclusions. 6 10
