# Alliance Risk vs Chubb Umbrella and Excess Liability Insurance

Alliance Risk brokers illustrative $1M–$25M layers; Chubb underwrites umbrella and excess by segment, including energy and construction, through appointed brokers.

## Research Scope and Use

Use this comparison to evaluate Alliance Risk and Chubb for Umbrella and Excess Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Alliance Risk places umbrella and excess rather than underwriting it, with typical limits from $1 million to $25 million or more. Chubb underwrites umbrella and excess casualty directly, with separate options for large global accounts, mid-sized companies, energy and construction, plus an Express Umbrella platform for appointed brokers.

## What Is Alliance Risk?

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Umbrella and Excess Liability Insurance?

Commercial umbrella insurance can provide additional liability limits above scheduled underlying policies for covered claims. Don't assume umbrella and excess liability are the same coverage — the labels aren't proven synonyms. [9](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide")

## Key Differences in Umbrella and Excess Liability Insurance

### Arranging the Layer Versus Writing It

Alliance Risk places umbrella and excess that sit above a client’s underlying GL, auto or employer’s liability. Chubb underwrites umbrella and excess casualty itself, spanning smaller and mid-sized companies through global multinationals, and also offers umbrella as an add-on inside its small-business Total Account Solution. [3](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") [7](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [8](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")

### Construction as a Shared Industry, Different Role

Both firms mention construction. Alliance Risk lists construction firms among buyers who commonly need the layer. Chubb structures a dedicated construction-industry option alongside energy, mid-sized and large global/national programs, and says it specializes in lead umbrella and excess for large global and national companies. Alliance Risk publishes typical limits of $1 million to $25 million or more; Chubb’s reviewed casualty page does not publish attachment points or limit amounts. [3](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") [7](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")

### How a Quote Starts

Alliance Risk’s umbrella page uses the same “Get a Quote” contact form as its other products and does not describe a line-specific checklist. Chubb offers Express Umbrella so appointed brokers can reserve, quote, bind and issue, and also lets you request a quote online or through an appointed agent. [3](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") [7](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance")

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

- Ask whether you are buying Chubb paper (lead umbrella, mid-sized excess, energy or construction) or an Alliance Risk placement with another carrier. [7](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [3](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance")
- Get numeric limits from Chubb; Alliance Risk’s $1–$25 million figures are illustrative ranges, not your quote.

- If you are a small account, ask Chubb whether umbrella is inside Total Account Solution or a standalone casualty placement. [8](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")
- Confirm who your appointed broker is for Express Umbrella versus Alliance Risk’s contact form.
