E&O (Professional Liability) vs. General Liability
One policy responds when your work goes wrong; the other responds when someone gets physically hurt or their property is damaged. They sound similar, but a claim built on bad advice and a claim built on a bruised knee land in completely different places.
At a glance
| E&O / Professional Liability E&O | General Liability (GL) GL | |
|---|---|---|
| What it covers | Financial harm to clients from your professional services, advice, errors, or omissions | Third-party bodily injury, property damage, and personal and advertising injury |
| When it applies | When a client alleges your work was negligent, late, or fell below professional standards | When a non-employee is physically injured or their property is damaged in connection with your business |
| Typical cost | Varies widely by profession and revenue; higher-risk advisory fields cost more | Generally a lower, more predictable premium based on the type of operation |
| Key limits or exclusions | Usually written claims-made, so timing and retroactive dates matter; excludes bodily injury | Excludes professional mistakes, your own faulty work product, and financial-only losses |
| Best suited for | Consultants, agents, designers, tech firms, and other advice or service providers | Nearly any business with a physical presence or public-facing operations |
Physical harm versus a professional mistake
General liability deals in the tangible - a visitor trips over a cord, or your crew cracks a client's window. It pays for bodily injury and property damage to others. What it explicitly steps around is the quality of your professional work; if the harm is purely financial and flows from your advice or service, GL typically does not respond.
Errors and omissions coverage lives in exactly that gap. It answers claims that you were negligent in performing professional services - a missed deadline, a flawed design, a bad recommendation - where the client's loss is money, not a broken bone. Because the two policies cover different injuries, most professional firms need both rather than choosing between them.
Claims-made timing matters
Most E&O is written on a claims-made basis, meaning the policy must be active both when the work was done and when the claim is filed. Watch the retroactive date and consider tail coverage if you switch carriers or close the business, or old work can go unprotected.
The Declarations page trigger and dates
Check whether coverage is claims-made or occurrence, and on E&O note the retroactive date that sets how far back covered work reaches.
The professional services definition
E&O forms define the covered professional services; make sure the wording matches what your business actually does, or a claim can fall outside it.
The general liability exclusions
GL forms carry a professional services exclusion; reading it shows exactly where GL stops and E&O must take over.
What it looks like on a real claim
Example 1 — A consultant's flawed recommendation
A consultant advises a strategy that costs the client $120,000 in losses. No one is hurt and nothing is physically damaged.
E&O responds to the negligence claim, covering defense and the financial loss up to the limit
GL does not apply because the loss is purely financial from professional advice
Example 2 — A client injured at a meeting
During an on-site visit, a client trips over the consultant's equipment case and breaks a wrist, leading to a $30,000 injury claim.
E&O does not cover bodily injury, so it does not respond to this claim
GL covers the third-party bodily injury, paying medical costs and defense
The bottom line
Match the policy to the way you could hurt someone. If clients rely on your judgment, advice, or specialized work, E&O covers the financial fallout when that work is challenged. If people and property come into contact with your business physically, general liability covers those injuries. Most service firms carry both because each closes a gap the other leaves open.
The costly mistake is assuming general liability covers professional errors - it does not, thanks to the professional services exclusion. A second trap is the claims-made structure of E&O: let it lapse or ignore the retroactive date, and past work can end up uncovered even though you paid premiums for years.
