## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them.

## Key Differences in Umbrella and Excess Liability Insurance

### Chubb documents an online broker workflow

Chubb says appointed brokers can reserve, quote, bind, and issue umbrella business through Express Umbrella. Liberty Mutual lists umbrella/excess in its commercial catalogue and as an option for wholesale businesses, but directs buyers through brokers and agents without describing a digital platform in the reviewed claims. Ask your broker whether your account can use Chubb Express Umbrella and what placement route Liberty Mutual offers. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [8](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")

### Chubb separates business segments

Chubb describes tailored umbrella/excess options for global and national firms, mid-sized companies, energy, and construction, as well as small-business coverage in Total Account Solution. Liberty Mutual names wholesale distribution as one target industry and also lists the line in its broader commercial catalogue. Share your industry and size with each broker to identify the right underwriting team and form. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [7](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions")

### Limits depend on which Chubb route you use

Chubb's small-business package describes umbrella as an additional layer but does not publish its limit there; its larger and mid-market offerings are described separately. Liberty Mutual's reviewed product pages likewise do not state umbrella limits or attachment points. Ask both for the available limits over your scheduled underlying policies, and ask Chubb whether the small-business package can meet your required amount. [5](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business") [8](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Chubb whether Express Umbrella is available through your broker and whether the quoted route is a small-business add-on or standalone placement. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")
- Ask Liberty Mutual's representative for attachment points, available limits, and which underlying policies qualify. [8](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")
