Key Differences in Commercial Property Insurance
Coverage and Valuation
Lockton says it can tailor a proprietary manuscript form to a client’s property needs and lists review of policy terms, deductibles, exposure values, and catastrophe modeling. MMA describes arranging coverage around an organization’s stated property risks but does not specify manuscript forms or modeling services. Complex portfolios should ask how wording and deductibles will be shaped to their locations. 4 7
Placement and Buyer Service
Lockton says the same property team that meets a client negotiates with underwriters directly. MMA routes property buyers to an adviser or specialist. Ask who will negotiate the wording and then review the issued policy against the negotiated terms; this is especially useful when locations share a layered program. 4 7
What to Confirm in Commercial Property Insurance Quotes
- Ask Lockton which manuscript clauses, retentions, and catastrophe models apply to the proposed portfolio. 4
- Ask MMA whether the quote uses standard or manuscript forms and who checks policy wording after binding. 7
- Ask both to identify the insurer, scheduled locations, valuation basis, limits, deductibles, and exclusions. 4 7
