These two policies sound similar and are often confused, but they protect against very different types of claims. Buying the wrong one — or only one when you need both — can leave significant gaps in your business coverage.
What General Liability Covers
General liability (GL) insurance protects your business against claims of bodily injury and property damage caused to third parties. The classic examples: a client slips and falls in your office, a contractor accidentally breaks a pipe and floods a building, or your product causes an injury.
GL also typically covers personal and advertising injury — meaning claims of libel, slander, copyright infringement, or false advertising. If you run ads, have a website, or publish any content, this matters.
Think of GL as protecting against physical and reputational harm your business causes to others in the real world.
What Professional Liability Covers
Professional liability — also called errors and omissions (E&O) or malpractice insurance — protects you against claims that your professional advice, services, or work caused a financial loss. No physical injury required.
Examples: a financial advisor gives incorrect guidance that costs a client money, an accountant makes a filing error, a consultant's strategy recommendation leads to a business loss, a real estate agent misrepresents a property. These claims wouldn't be touched by a GL policy — they're pure economic harm arising from professional services.
The Critical Difference
General liability is about what happened physically. Professional liability is about what you said or did professionally. A contractor who drops a tool on a client's roof (property damage) has a GL claim. A contractor who gives incorrect load-bearing guidance that causes a structural failure may have a professional liability claim — because the damage arose from professional advice, not a physical act.
Many businesses need both. Some primarily need one.
Who Needs General Liability
Almost every business that has physical operations, a physical location, or interacts with clients in person should carry GL. This includes retailers, contractors, restaurants, landlords, service businesses, and most small businesses. It's often required by leases and client contracts.
Who Needs Professional Liability
Any business that provides professional advice, expertise, or services should carry professional liability, including:
- Consultants and coaches
- Accountants and bookkeepers
- Real estate agents and property managers
- IT professionals, developers, and designers
- Healthcare providers
- Architects and engineers
- Insurance agents (yes, we carry it too)
If your clients pay you for your knowledge, judgment, or recommendations — professional liability belongs in your program.
When You Need Both
Many businesses operate in a space where both physical and professional risks exist. A marketing agency might have a client visit their office (GL) and make a campaign recommendation that performs poorly (professional liability). An IT firm might damage hardware during an on-site visit (GL) and make a software configuration error that causes downtime (professional liability).
Getting both doesn't have to be expensive — many carriers bundle them or offer favorable pricing when placed together. That's one advantage of working with an independent agent who can package your coverage across the market.
A Note on Business Owner Policies (BOPs)
A Business Owner Policy typically includes GL and commercial property coverage, but not professional liability. If you're buying a BOP and you provide professional services, you'll likely need to add a separate professional liability policy. See our guide on how to choose the right BOP for more detail.
