What Is Professional Liability Insurance (E&O) and Who Needs It?

Informational only. This article does not constitute insurance, legal, or financial advice. Coverage terms vary by carrier, policy, and jurisdiction. Full disclaimer.

General liability covers accidents. Professional liability covers something different — claims that your professional advice, service, or skill caused a client financial harm or physical injury. If you provide a service where a mistake in your work could hurt someone, you likely need it.

Also called: Professional liability goes by several names depending on the industry: errors & omissions (E&O), professional indemnity, malpractice insurance (for medical professions), and technology E&O (for tech businesses). They're all variations of the same coverage type.

What professional liability covers

What professional liability does NOT cover

Who needs professional liability?

You need it if clients could claim your work or advice caused them harm:

Business typeWhy professional liability matters
Personal trainers, yoga instructorsInstruction technique claims, injury from exercise programming
Estheticians, lash techsChemical burns, skin reactions, service-caused damage
Wedding photographersLost files, missed shots, failure to deliver
Event planners, DJsVendor no-shows, failed event execution claims
Dog trainersTraining methods causing behavioral harm claims
Swim instructors, coachesImproper instruction causing injury
Bookkeepers, consultantsBad advice resulting in financial loss
Tip: Many carriers bundle GL + professional liability into a single policy for common service businesses. The combined cost is typically $100–$300 more per year than GL alone — and completely changes what you're protected against.

How it's different from GL

The key distinction: GL covers what happens during the physical delivery of your service (accidents, damage, injury). Professional liability covers claims about the quality or outcome of your service (you did it wrong, you didn't deliver, your advice caused harm).

Example: A yoga instructor's student trips on a mat block during class — GL claim. The same student claims the instructor's adjustment technique caused a back injury — professional liability claim.

The most common mistake: Businesses in high-skill service professions (instructors, coaches, consultants, creative professionals) buy GL and think they're covered. They're not covered for the claims most likely to actually happen to them. Get both.
Bottom line: If you teach, train, advise, design, or deliver a skilled service, professional liability is not optional. It covers the claims that matter most to your type of business — and GL won't help you when those claims arise.
