General liability vs professional liability — what each actually covers
The difference fits in one line: general liability covers accidents; professional liability covers mistakes. A customer slipping on your wet floor is general liability. A client losing money because your advice was wrong is professional liability.
The confusion comes from the gap between those two — real incidents don't announce which policy they belong to, and buying the wrong one means paying premiums for years and discovering at claim time that you bought cover for the wrong failure mode. Here's how the line is actually drawn.
What general liability covers
General liability (GL) responds when your business operations injure someone else's body or property — people who aren't your employees, property that isn't yours. It's the policy behind almost every certificate of insurance a landlord, event organizer or general contractor demands.
- Bodily injury: a customer slips in your salon, a mower throws a stone at a passerby, a guest trips over your power cable
- Third-party property damage: paint on a client's carpet, a flooded ceiling below your plumbing work, a fryer fire at a rented venue
- Products: someone gets sick from food you sold (product liability usually rides along with GL for food businesses)
- Advertising injury: claims of slander, libel or copying a competitor's ad
What professional liability covers
Professional liability — also sold as errors & omissions (E&O) — responds when your service or advice itself causes a financial loss or harm, even with no accident in sight. Nobody fell, nothing burned; the work was just wrong, late or negligent.
- A consultant's recommendation costs the client money and they sue
- A web developer misses a launch deadline and the client claims lost revenue
- An esthetician's chemical peel scars a client (the *treatment* caused the harm — this is professional liability territory, not GL)
- A bookkeeper's error triggers a client's tax penalty
- Defense costs for accusations that turn out to be groundless — usually the real value of the policy
The same incident, two different policies
The dividing question adjusters ask: did the harm come from your operations and premises, or from the professional service itself? The table shows how it splits in practice:
| Scenario | Policy that responds |
|---|---|
| Client trips over your laptop bag during a meeting | General liability |
| Your advice in that meeting loses the client $50k | Professional liability |
| Salon customer slips on a wet floor | General liability |
| Salon color treatment burns a customer's scalp | Professional liability |
| Your ladder falls and dents a car | General liability |
| You inspected the roof and missed the leak that ruined the attic | Professional liability |
Who typically needs which
Trades and physical businesses (cleaning, lawn care, salons, food, contractors) get asked for GL constantly — it's the certificate everyone demands — and add professional liability when their work involves treatments or judgment calls that can go wrong without an accident.
Advice and service professionals (consultants, designers, IT, marketing, bookkeepers) are the reverse: professional liability is the policy that matches how they actually get sued, and a small GL policy covers the office-and-meetings risk around it.
Many small businesses end up with both, often via a business owner's policy (BOP) — but note: a BOP bundles GL with commercial property, not with professional liability. E&O is almost always a separate line item; assuming your BOP includes it is one of the classic claim-time surprises.
What they cost
Both are among the cheaper commercial lines. Published carrier averages: The Hartford reports ~$67/month average for GL; NEXT says about half its GL customers pay under $25/month; MoneyGeek's 2026 sample priced Hiscox GL at ~$114/month. Professional liability for low-risk consultants commonly lands in the $30–80/month range depending on revenue and industry.
Price differences of a few dollars matter less than claims behavior — the policies only exist for the day you use them. Every insurer selling these lines is on our compare tool with its NAIC complaint record next to its price.
Common questions
Is professional liability the same as E&O?
Yes — errors & omissions (E&O) and professional liability are the same coverage under different names. Some industries say malpractice (medical, legal); it's the same concept: financial harm from professional services.
Does general liability cover my own injuries or property?
No. GL is strictly third-party — other people, other people's property. Your own gear needs property or tools & equipment coverage; your own injuries need health/disability cover, and employees need workers' compensation.
Does a BOP include professional liability?
Almost never by default. A business owner's policy bundles general liability with commercial property. Professional liability/E&O is bought separately or as an add-on line.
Can I be required to carry both?
Yes — client contracts frequently demand GL certificates, and contracts for advice-based work (consulting, IT, design) increasingly require proof of professional liability too, typically $1M per occurrence.
