Business insurance / Liability structure
General Liability vs. E&O Insurance
General liability and professional liability protect against different categories of liability. For a professional-service firm, understanding that boundary matters because one claim can contain both premises or property-damage allegations and allegations arising from professional advice or services.
General liability
Bodily injury, property damage and premises exposure.
A CGL policy is commonly built around third-party bodily injury, property damage and personal/advertising injury, subject to the form’s insuring agreements, exclusions and endorsements.
E&O / professional liability
Financial harm tied to professional services.
E&O is designed around allegations of negligence, errors or omissions in covered professional services. The operative definitions and exclusions vary by profession and carrier.
Why professional firms often need both.
A professional office can have ordinary premises and operations exposures even if its principal risk is professional advice. A client can slip in the office. An employee can damage property while visiting a client location. A landlord may require CGL. Separately, a client can allege that advice, documentation, design, placement, analysis or other professional work caused financial loss.
Travelers specifically distinguishes these categories: general liability does not substitute for professional liability when the alleged damage arises from advice or recommendations in professional services. Likewise, neither GL nor E&O should be assumed to cover business property or business-use automobile exposures.
Claim examples
The allegation tells you which policy to read first.
- Client slips in reception: generally a premises/general-liability question.
- Consultant gives incorrect advice: generally a professional-liability question.
- Property manager damages a tenant’s property while performing work: GL and professional-services wording may both need review.
- Real-estate broker is accused of misrepresentation: the E&O form and its professional-services definition become central.
- Employee driving to a client meeting causes an accident: commercial auto or hired/non-owned auto may be implicated.
What to review in the CGL.
- Who qualifies as an insured
- Premises and operations coverage
- Products/completed operations if applicable
- Damage to rented premises
- Additional insured requirements
- Professional-services exclusions or limitations
- Contractual liability
- Cyber/data exclusions
- Hired/non-owned auto treatment
- Umbrella eligibility and underlying limits
Policy-reading note
Do not decide coverage from the policy label alone.
Review the actual CGL professional-services exclusion, the E&O Professional Services definition, insured status, contractual liability, defense provisions and endorsements together. Mixed allegations can create allocation and coverage questions that vary materially by form.
