Commercial umbrella insurance
Commercial umbrella insurance is business liability coverage above specified underlying policies, such as commercial general liability or commercial auto. It can pay covered damages and defense costs after the underlying limits are used up, and some forms address certain coverage gaps. The declarations, exclusions, retained limit and endorsements decide the actual protection.
Also called: excess liability coverage, excess liability, commercial umbrella
A commercial umbrella is a second layer of liability insurance for a business. Your general liability insurance, commercial auto or other scheduled policy pays a covered claim first, and the umbrella pays covered damages above those limits, up to its own limit. It does not pay to repair your own building, vehicles, equipment or inventory, because it is liability coverage, not property coverage, according to the NAIC (opens in a new tab).
How an umbrella pays above your underlying policy
Contracts often set the umbrella limit. A Connecticut state construction contract ties it to contract value: $1,000,000 for contracts up to $500,000, $2,000,000 for contracts from $500,000.01 to $1,000,000, and $5,000,000 for contracts from $1,000,000.01 to $10,000,000, according to the Connecticut Department of Administrative Services (opens in a new tab). Say a business with $1,000,000 of underlying liability coverage and a $1,000,000 umbrella faces a covered $1,400,000 judgment.
Hover or tap a row to highlight it.
| Item | Amount |
|---|---|
| Covered liability judgment | $1,400,000 |
| Underlying policy pays | $1,000,000 |
| Umbrella pays ($1,400,000 minus $1,000,000) | $400,000 |
| Judgment left unpaid | $0 |
| Umbrella limit remaining | $600,000 |
If the covered judgment were $2,300,000 instead, the underlying policy and the umbrella would each pay $1,000,000, leaving $300,000 unpaid. The judgment amounts are illustrations. The real payment depends on whether the loss is covered, whether the underlying policy applies, any retained limit, how defense costs are treated, the aggregate limits and the settlement terms.
Limits, retentions and form choices
The per-occurrence limit is the most the umbrella pays for one occurrence, commonly $1 million, $2 million, $5 million or another amount you select or a contract requires. The annual aggregate caps all covered payments in the policy period, and the Connecticut construction contract requires the aggregate to be at least twice the highest per-occurrence limit. Higher limits change how much is available; underlying limits and any retained limit change when the umbrella starts paying.
The umbrella's schedule lists the underlying policies, such as general liability, auto liability and employers liability where the form permits, and the limits you must keep in force. If you let an underlying limit lapse, you may have to fund the missing layer yourself. A self-insured retention is the amount you pay before certain umbrella coverage applies. Defense costs can sit inside or outside the umbrella limit, and coverage can be occurrence or claims-made. Endorsements can add additional insureds, contractual liability, pollution or employment-practices coverage. Premium depends on operations, claims history, underlying limits, the umbrella limit, vehicles, payroll and sales.
Umbrella, excess liability and personal umbrella
Excess liability coverage generally follows the underlying policy's terms and responds after its limit runs out. An umbrella can do the same and can also cover certain gaps the underlying policy leaves, subject to its own retained limit and exclusions. The two labels are used together often enough that the policy form, not the name, tells you which you have. A personal umbrella sits over personal auto, homeowners, condo or renters policies and does not cover your business activities. Our guide on whether you need umbrella insurance covers the personal side.
Where you see the term
You meet a commercial umbrella on a quote or proposal, a binder, the declarations page, the schedule of underlying insurance, follow-form or additional insured endorsements, a renewal notice, and claim or reservation-of-rights letters. The declarations page usually shows the umbrella limit, retained limit, policy period, covered entities, scheduled underlying policies and aggregates. The standard ISO commercial umbrella form (opens in a new tab) pays the "ultimate net loss" for covered bodily injury, property damage, or personal and advertising injury in excess of the underlying insurance. A certificate of insurance is evidence of coverage and does not change the policy unless an endorsement does.
How Connecticut and New York rules apply
Neither state requires every business to buy an umbrella, but a contract can. Connecticut's state construction conditions require the umbrella or excess policy to name the State of Connecticut as an additional insured unless it follows the underlying policies on a complete follow-form basis. Our Connecticut umbrella insurance guide covers coverage in that state.
In New York, N.Y. Insurance Law § 3426 (opens in a new tab) treats a commercial umbrella written over underlying policies with at least $500,000 of aggregate coverage as an excess liability policy. The same section governs cancellation and nonrenewal, and it lets an excess liability insurer condition renewal on requirements about your underlying coverage. Commercial umbrella policies should not treat workers compensation and employers liability as underlying coverages for rating and form purposes in the circumstances described in New York Circular Letter No. 17 (opens in a new tab).
Questions to ask an agent or insurer
- Which underlying policies are scheduled, and what limits must stay in force? The umbrella may not respond until those limits are used up.
- Does the policy follow form, go broader than the underlying policies, or apply a retained limit to gaps? The word "umbrella" alone does not tell you whether an underlying exclusion is covered above it.
- What are the per-occurrence limit, annual aggregate, self-insured retention and defense-cost treatment? These decide how much the insurer pays and when.
- Are my operations, vehicles, products, locations, employees and contracts included? The schedule, definitions and exclusions decide whether your exposure matches the policy.
- What notice, consent-to-settle and reporting duties apply? Missing a condition can affect defense or payment.
Frequently asked questions
Short answers for business owners comparing umbrella coverage.
Does commercial umbrella insurance replace general liability insurance?
No. It sits above your underlying liability insurance, which pays first. The umbrella responds only as its form provides, after the underlying limit or retained limit.
How much commercial umbrella coverage does a business need?
The amount usually comes from contracts, leases, lenders, government procurement rules, your exposures and your underlying limits. Read the insurance clause in each contract and ask the agent whether the proposed policy meets it.
Why did my umbrella renewal premium go up?
The umbrella limit is only one factor. Changes in underlying limits, exposures, claims, audits and underwriting can all change renewal terms.
