General liability insurance usually responds to covered third-party bodily injury, property damage, and certain personal or advertising injury claims. Professional liability insurance usually responds when a client alleges that advice, services, an error, omission, negligence, or missed deliverable caused financial loss.

In plain language:

• General liability addresses many physical risks arising from business operations.
• Professional liability addresses risks arising from the work, advice, or expertise your business provides.

Key Takeaways

• Commercial General Liability (CGL) is commonly called general liability insurance.
• Professional Liability Insurance is also commonly called Errors & Omissions (E&O) Insurance.
• CGL and professional liability address different claim triggers.
• One policy generally does not replace the other.
• Businesses with both physical operations and professional service exposures may need both.
• Contracts, regulatory requirements, operations, and policy wording should drive the decision.

Professional Liability vs. General Liability: The Key Difference

The practical difference is the nature of the allegation.

General Liability

Primary Claim Trigger: Third-party bodily injury or property damage

Example: A client trips and falls at your office

Common Gap: Professional errors are generally not covered

Professional Liability

Primary Claim Trigger: Financial loss arising from professional work

Example: A client alleges faulty advice caused a financial loss

Common Gap: General premises-related injuries are generally not covered

Businesses with Both Exposures

Many organizations face both physical and professional exposures.

Example: A consultant working at a client’s office may face:

• General liability exposure if property is damaged
• Professional liability exposure if services or advice cause financial loss

Broader Risk Review

Insurance decisions should be based on a review of your operations, contracts, and exposures, not solely on a contract checklist or policy title.

When Might a Business Need Both?

A business may require both policies if it:

• Provides professional services
• Interacts with clients in person
• Operates from physical premises
• Attends events
• Visits job sites
• Sells products
• Employs people
• Handles client property

Technology Consultant

CGL Question:
Did the consultant damage equipment at the client’s premises?

Professional Liability Question:
Did programming, advice, or implementation cause financial loss?

Was someone injured at an event or office?

Professional Liability Question:

Did advice, analysis, documentation, or a missed deadline cause financial loss?

Additional Consideration:
Regulatory bodies or client contracts may impose specific insurance requirements.

How Policy Structure Can Change the Answer

Commercial General Liability policies are often written on an occurrence basis.

Professional Liability policies are often written on a claims-made basis.

The actual policy wording governs coverage.

Important Claims-Made Considerations

• Retroactive date
• When the claim is first made
• Reporting requirements
• Whether defence costs reduce available limits
• Whether an extended reporting period is available
• Whether prior acts are covered when changing insurers

Do not cancel or replace professional liability coverage without reviewing continuity carefully. A change in retroactive dates or a reporting gap can create significant coverage issues.
