Does General Liability Insurance Cover Professional Mistakes?

No. General liability insurance does not cover professional mistakes. GL covers physical bodily injury and property damage to third parties. A professional mistake, meaning an error, omission, or negligent act in the performance of professional services, requires errors and omissions insurance, also called professional liability or E&O coverage.

This is a significant coverage gap for consultants, accountants, IT professionals, designers, financial advisors, and anyone else who provides advice or professional services as part of their business.

What GL Covers

General liability covers:

• Bodily injury: a customer, visitor, or third party is physically injured by your business operations
• Property damage: you or your employees damage third-party property
• Advertising injury: defamation, copyright infringement, or unfair competition claims from your advertising

GL is built for tangible, physical harm. A contractor who drops a tool through a client's skylight has caused physical property damage covered by GL. A customer who slips on a wet floor in your store has suffered bodily injury covered by GL.

What Professional Liability (E&O) Covers

Professional liability covers:

• Errors: mistakes in work product, advice, or services you deliver
• Omissions: failing to do something you should have done as part of your services
• Negligent acts: acts of professional negligence in delivering your services

E&O pays for legal defense and damages when a client claims your professional services caused them financial harm.

Examples:

• An accountant files an incorrect tax return and the client owes penalties
• A financial advisor recommends an investment that performs poorly and the client claims negligence
• An IT consultant misconfigures a system and the client loses data
• A marketing consultant runs a campaign with a factual error that damages the client's reputation
• A lawyer misses a filing deadline and the client loses their case

None of these scenarios involve physical injury or tangible property damage. They involve financial harm from professional services. GL does not cover them.

The Professional Services Exclusion in GL

Most GL policies include a professional services exclusion. This exclusion explicitly removes coverage for claims arising from the rendering or failure to render professional services. The exclusion applies broadly to advice, recommendations, instructions, and any services that require professional skill or judgment.

For businesses that provide both physical services and professional advice, the line matters. A plumber who installs a pipe incorrectly (physical work that causes water damage) has a GL claim. A plumber who advises a client on the wrong pipe specification (professional recommendation) that later causes a problem is in E&O territory.

When You Need Both

Many businesses need both GL and professional liability:

• An architect needs GL for bodily injury and property damage on a job site and E&O for design errors
• A web developer needs GL for premises liability at their office and E&O for code errors that cause client losses
• A management consultant needs GL for general business operations and E&O for advice that clients claim was negligent

Some industries face mixed claims where both policies may be relevant. An engineer who advises on a structural design and a component fails, causing physical property damage, may have both a GL claim (physical damage) and an E&O claim (negligent professional advice) arising from the same incident. Having both policies avoids a coverage gap.

Professional Liability vs. E&O vs. Malpractice

These terms refer to the same type of coverage for different industries:

• Errors and Omissions (E&O): used in technology, consulting, insurance, real estate, and most non-medical professional services
• Malpractice: used in medical, legal, and accounting contexts
• Professional Liability: the general term covering all of the above

The coverage structure is similar across contexts. The specific policy language is tailored to the industry.

Frequently Asked Questions

I provide consulting services and I have GL. Am I covered for a mistake in my advice?

No. The professional services exclusion in your GL policy removes coverage for claims arising from your consulting advice. You need errors and omissions insurance to cover professional advice claims.

A client claims my bad recommendation cost them money. Which policy covers that?

Professional liability (E&O) covers financial loss claims from errors or negligence in professional services. GL does not. If you only have GL, this claim is likely excluded.

Do I need E&O if I also have a contract with a limitation of liability clause?

A contract clause limits your contractual liability but does not prevent a client from suing you for negligence outside the contract. E&O covers the defense costs and any judgment or settlement even when you believe you are contractually protected. Defense costs alone for a professional liability claim can reach $50,000 to $150,000 before any verdict.

What industries typically need both GL and E&O?

Architecture, engineering, technology, marketing, accounting, legal, insurance, financial services, and real estate all typically carry both. Any business that provides advice or professional services alongside physical business operations should have both policies.

How much does E&O insurance cost?

E&O premiums vary significantly by profession, revenue, and claims history. A small consulting firm might pay $800 to $2,500 per year. Technology companies with software liability exposure pay more. Medical malpractice premiums are substantially higher than most other E&O categories.
