Why CGL Matters
Commercial General Liability insurance is the most fundamental coverage in commercial insurance. Nearly every business needs it. Most leases require it. Many contracts demand it. It is often the first policy a new business purchases and the last one they would cancel.
For agents building a commercial book, CGL knowledge is not optional — it is the foundation of your expertise. Clients expect you to understand what their CGL covers, what it does not cover, and what additional coverages they need to close the gaps.
The Three Coverages in a CGL Policy
Coverage A: Bodily Injury and Property Damage Liability
This is the core of the CGL policy. It covers your legal liability when your business operations cause physical injury to someone or damage to someone else's property.
Examples:
- A customer slips on a wet floor in your store and breaks their hip
- Your product causes injury to a consumer (products liability)
- A contractor's work damages a client's existing property
- Your employee accidentally damages a customer's vehicle while loading equipment
Coverage A is written on an occurrence basis — meaning it covers events that occur during the policy period, regardless of when the claim is actually filed. This provides long-term protection that claims-made policies do not.
Coverage B: Personal and Advertising Injury Liability
This covers non-physical injuries caused by your business activities:
- Libel and slander: Making false statements that damage someone's reputation
- False arrest or detention: Wrongfully detaining a suspected shoplifter
- Invasion of privacy: Using someone's image without permission in advertising
- Copyright infringement: In your advertising materials (with limitations)
- Wrongful eviction: For landlords who improperly evict tenants
Coverage C: Medical Payments
Medical payments coverage (MedPay) pays for minor medical expenses when someone is injured on your premises or by your operations — regardless of fault. The limits are small (typically $5,000-$10,000) and the purpose is to handle minor injuries quickly without a lawsuit. Think of it as goodwill coverage — paying for a customer's emergency room visit before they decide to sue.
What CGL Does NOT Cover
Understanding CGL exclusions is just as important as understanding what it covers. Major exclusions:
- Automobile liability: Any claim arising from the use of a vehicle is excluded. This is why hired and non-owned auto coverage is critical.
- Workers compensation: Employee injuries on the job are excluded — covered by workers comp instead.
- Professional errors: Mistakes in your professional services (design errors, bad advice) are excluded — covered by E&O insurance.
- Your own property: Damage to property you own, rent, or have in your care is excluded — covered by commercial property insurance.
- Pollution: Most pollution claims are excluded under the absolute pollution exclusion. Environmental liability requires separate coverage.
- Intentional acts: Deliberate harm is never covered by liability insurance.
- Contractual liability: Limited — CGL covers liability assumed under an "insured contract" but not all contractual obligations.
Understanding CGL Limits
CGL policies have a multi-layered limit structure that agents must understand:
- Each Occurrence Limit: Maximum per single event (standard: $1,000,000)
- General Aggregate: Maximum for all claims during the policy period (standard: $2,000,000)
- Products/Completed Operations Aggregate: Separate aggregate for product liability and completed work claims (standard: $2,000,000)
- Personal & Advertising Injury: Per-person/organization limit (standard: $1,000,000)
- Damage to Rented Premises: Per-premises limit (standard: $100,000-$300,000)
- Medical Expense: Per-person limit (standard: $5,000-$10,000)
The critical concept: once the general aggregate is used up, there is no more coverage for the rest of the policy period. A business with multiple claims in one year can exhaust their aggregate and be left unprotected. This is why umbrella/excess coverage exists — to provide additional limits above the CGL.
Key Endorsements Agents Should Know
- Additional insured: Adds other parties (landlords, general contractors, clients) as insureds on your policy. One of the most commonly requested endorsements in commercial insurance.
- Waiver of subrogation: Prevents your carrier from recovering claim payments from another party. Often required in construction contracts.
- Per-project or per-location aggregate: Changes the aggregate from policy-wide to per-project or per-location, providing higher effective limits for businesses with multiple sites or projects.
- Employee as additional insured: Extends coverage to employees for their personal liability arising from business activities.
CGL in Practice
For agents building commercial books, CGL expertise sets you apart:
- Review every client's CGL policy for adequacy — not just limits, but endorsements and exclusions
- Understand industry-specific CGL needs (contractors need different endorsements than retailers)
- Know when to recommend higher limits or umbrella coverage
- Explain coverage gaps clearly — clients trust agents who educate rather than just sell
- Present CGL as part of a comprehensive commercial package, not a standalone policy
The agents who deeply understand CGL — and can explain it in plain language to business owners — are the ones who build the strongest, most trusted commercial relationships.
