Umbrella or excess insurance can add liability limits above selected underlying policies when a covered claim exceeds them; compare the schedule and any gaps. ## Umbrella and Excess Liability Insurance Summary 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.

An umbrella’s high limit can still leave gaps for specialty claims, including employment-practices or professional-liability allegations. Ask which exposures the quote excludes by name. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) Umbrella insurance can add liability limits above selected policies when a covered claim exceeds their limits. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### Additional Limits for Covered Claims Ask what the quote calls umbrella or excess coverage, and compare its underlying policies, attachment terms and any additional coverage. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [3](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm) [4](https://www.coverdash.com/coverage) ## Who Needs Umbrella and Excess Liability Insurance? Consider extra liability limits when a large claim could exceed your primary coverage or a contract requires higher limits. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [5](https://kinro.com/products) ## Umbrella and Excess Liability Insurance Coverage Examples ### A Claim Reaches Your Primary Limit A covered liability claim uses up the limit of your primary policy. An umbrella or excess layer may provide additional limits if that policy is scheduled underneath it and the claim meets the attachment terms. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [5](https://kinro.com/products) [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### Your Primary Policy Excludes a Claim A claim is excluded by your primary policy, and you turn to the umbrella. The umbrella may not fill the gap. Any broader protection depends on its own coverage terms, exclusions and self-insured retention. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [3](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm) [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) ## How Do You Compare Umbrella and Excess Liability Insurance Coverage and Costs? ### Underlying Policies, Attachment and Gaps Confirm which policies are listed as underlying insurance and at what limits. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [5](https://kinro.com/products) The extra layer begins paying according to its attachment terms. It may respond after a single occurrence uses up the primary limit, after the primary aggregate is exhausted, or on another stated basis. Confirm the terms for each underlying policy, including auto if you need it covered. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [6](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/business-vehicle-insurance) [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [5](https://kinro.com/products) Ask whether the quote can respond when an underlying policy does not, and what self-insured retention would apply in that case. [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [3](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm) | Quote detail | Ask the insurer | | --- | --- | | Underlying schedule | Which policies and limits must sit underneath this coverage? | | Attachment | Does the excess layer attach after an occurrence limit, an aggregate or another threshold? | | Response without underlying | Can it respond when an underlying policy does not, and what retention applies? | | Additional coverage | What claims does this layer cover that the underlying policies do not? | ### Auto, Specialty Exclusions and Contract Limits For auto claims, ask whether the commercial-auto or trucking liability policy is listed as underlying insurance. [6](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/business-vehicle-insurance) Ask whether employment-practices, professional-liability, product-recall and similar specialty exposures are included or excluded. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) Compare the extra limits with any contract-required liability limits and with the underlying limits those contracts assume. [5](https://kinro.com/products) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## How Does Umbrella and Excess Liability Insurance Compare With Related Coverage? An umbrella discussion does not replace checking the underlying general-liability, auto or employers-liability terms.

No. The underlying schedule identifies the policies and limits beneath it. Check that each policy you want covered is listed. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [5](https://kinro.com/products) ### Does It Always Fill a Gap in Primary Coverage? No. Any broader protection depends on the umbrella's terms and exclusions, and a self-insured retention may apply. [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [3](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm) ### When Do Commercial Umbrella Limits Start Paying? Check the attachment terms: the additional limits may apply after a covered occurrence exhausts an underlying limit, after an aggregate is exhausted, or on another stated basis. The quote should identify the required underlying limits. [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [1](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance) [2](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) [5](https://kinro.com/products) ### Can a Commercial Umbrella Sit Above Trucking or Auto Liability? It can, but check that the commercial-auto or trucking liability policy is listed as underlying insurance. Review the umbrella and primary policy terms together to establish how the additional limits apply.

It suits businesses serving customers or working on their premises; your own building, tools and stock need property coverage. - [What Is Commercial Auto Insurance?](https://thegeneralaverage.com/coverage/commercial-auto) — Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. - [What Is Trucking Insurance?](https://thegeneralaverage.com/coverage/trucking) — Trucking coverage can address liability, damage to your trucks and cargo losses, but one quote may not include all three. If you haul goods for customers or yourself, compare those protections and check whether the quote needs motor-carrier or other commercial auto coverage. ## Which Insurance Providers Offer Umbrella and Excess Liability Insurance? ### [AIG](https://thegeneralaverage.com/insurance-providers/aig) AIG Excess Casualty (lead umbrella and mid/high excess) ### [Alliance Risk](https://thegeneralaverage.com/insurance-providers/alliance-risk) Alliance Risk arranges umbrella and excess liability insurance. ### [Amelia Risk](https://thegeneralaverage.com/insurance-providers/amelia-risk) Amelia Risk arranges umbrella and excess liability. ### [Aon](https://thegeneralaverage.com/insurance-providers/aon) Aon lists umbrella and excess within construction liability coverage areas; ask whether either applies to your project and jurisdiction. ### [Berkshire Hathaway Specialty Insurance](https://thegeneralaverage.com/insurance-providers/berkshire-hathaway-specialty-insurance) BHSI lists lead umbrella and excess casualty within its U.S. casualty products. ### [biBerk](https://thegeneralaverage.com/insurance-providers/biberk) ### [CFC](https://thegeneralaverage.com/insurance-providers/cfc) CFC offers excess professional liability, general liability and cyber limits for small and micro businesses. ### [Chubb](https://thegeneralaverage.com/insurance-providers/chubb) Chubb offers umbrella and excess liability insurance. ### [CNA](https://thegeneralaverage.com/insurance-providers/cna) ### [Corgi](https://thegeneralaverage.com/insurance-providers/corgi) Corgi lists commercial umbrella liability insurance. ### [Coverdash](https://thegeneralaverage.com/insurance-providers/coverdash) Coverdash lists umbrella and excess liability insurance. ### [Founder Shield](https://thegeneralaverage.com/insurance-providers/foundershield) Founder Shield lists umbrella insurance. ### [Foxquilt](https://thegeneralaverage.com/insurance-providers/foxquilt) Foxquilt lists Umbrella/Excess in its primary-coverages list and has a current Umbrella Insurance page that distinguishes umbrella from excess.
