## What Are the Key Differences Between Chubb and Gallagher Umbrella and Excess Liability Insurance?

### Buying From the Insurer Versus a Program Broker

You can ask Chubb for an umbrella quote online or through an appointed agent, and its Express Umbrella tool lets brokers quote, bind and issue quickly. Mid-sized companies get excess casualty options with Chubb claims handling; large global firms get lead umbrella. Gallagher doesn't write the policy. It places umbrella and excess alongside auto, workers' comp and general and product liability, and designs custom or alternative-risk programs.

### What Gallagher Does Around the Placement

Before renewal, Gallagher meets your finance, HR, operations and risk leads. It runs a gap analysis, reviews contracts and forms, and has a claims and loss-control advocacy group. Chubb's page describes no comparable advisory work, since it's the insurer. Neither publishes limits.
