The math behind Security System Installers Umbrella / Excess Liability premiums

For Security System Installers, Umbrella / Excess Liability premium is calculated per $1M of underlying limit. ISO maintains the rating framework that most carriers use as a starting point, with each carrier layering on its own loss-cost multiplier and credit/debit factors.

How can Security System Installers reduce Umbrella / Excess Liability premiums?

Security System Installers that consistently come in below median on Umbrella / Excess Liability pricing tend to do the same handful of things. The most effective:

• Subcontractor COI tracking and indemnity wording
• Higher deductible election ($2.5K-$5K)
• Bundling under a single carrier vs monoline placements
• Claims-free three-year run with experience mod credit

The first item on the list usually delivers the largest single credit at renewal. Combined with the second and third, it is realistic for a clean security system installer to land 15-25% below the standard premium.
