E&O vs General Liability Insurance: What's the Difference?

These two policies get confused constantly, and the confusion is expensive — because the claim a business assumes is covered often lands in the gap between them. The clean distinction: general liability covers physical harm to others; E&O covers financial harm from your work. One guards against accidents in the physical world, the other against failures in your professional judgment. Most service businesses need both.

General liability: the physical world

General liability (GL) responds when your business causes bodily injury or property damage to a third party. A client trips in your office. Your team knocks over and breaks equipment at a job site. An ad you ran is alleged to be defamatory. The harm is physical or reputational, and it happens to someone outside your business. What GL covers.

E&O: the professional world

E&O (errors and omissions, a.k.a. professional liability) responds when your work, advice, or service causes a client a financial loss. No one got hurt; nothing broke. A consultant's strategy lost the client money. An IT firm's implementation failed and cost the client business. An accountant's error triggered a penalty. The harm is economic and tied to the quality of what you delivered. What is E&O.

Side-by-side

| | General Liability | E&O / Professional Liability | |---|---|---| | Covers | Bodily injury, property damage to others | Financial loss from your work or advice | | Trigger | A physical accident | An alleged error, omission, or negligence | | Example claim | Client slips in your office | Client says your work cost them money | | Policy structure | Usually occurrence-based | Usually claims-made | | Required by | Landlords, most clients | Clients buying expertise |

General liability vs professional liability.

Two examples that show the gap

A marketing agency. A client visits the office and trips over a cord, breaking their wrist — that's general liability. Separately, the agency runs a campaign that underperforms and the client claims the agency's strategy cost them six figures in lost sales — that's E&O. Same agency, same client, two unrelated risks. The GL policy won't pay the campaign claim; the E&O policy won't pay the trip-and-fall. Carry only one and half your exposure is naked.

An IT consultancy. An employee damages a client's server rack while installing hardware — general liability (property damage). The system they configured later fails and disrupts the client's operations — E&O (professional error). Different policies, no overlap.

Why you likely need both

If your business has any physical footprint — an office clients visit, work you perform on-site, equipment you handle — you have GL exposure. If you also sell advice, services, or expertise, you have E&O exposure. Most service businesses sit on both sides of that line, which is why most need both policies. Buying one and assuming it covers the other is among the most common and costly insurance mistakes. Common business insurance mistakes.

The analogy

GL and E&O are like a car's airbags and its warranty. The airbag protects against a crash — a sudden physical event (general liability). The warranty protects against the engine being built or serviced wrong — a failure in the work itself (E&O). Both protect the same car, but one is useless against the other's failure. You wouldn't skip the warranty because you have airbags. How to choose the right policy.

Which do you need?

• Physical premises, on-site work, or handling others' property → general liability.
• Selling advice, services, or expertise → E&O.
• Both → both policies, which is most service businesses.

A broker can look at what you actually deliver and confirm where your exposure sits — usually on both sides. How brokers help.
