Professional Liability (E&O) vs General Liability: Do You Need Both?

Service businesses often need both: General Liability covers injury and property damage, and Professional Liability (E&O) covers a client's financial loss from your mistakes. For consultants and service firms.

What do General Liability and Professional Liability each cover?

General Liability pays when your business hurts someone (bodily injury) or damages their things (property damage). It also usually includes limited coverage for claims over your own advertising, such as libel. It is not built for claims over content you create for clients. Ad, publishing and web design firms often need media liability or Professional Liability for that.

Professional Liability (E&O, for Errors & Omissions) pays for claims that your services caused a client a financial loss. Contracts often list both in the same clause:

• Per occurrence or per claim: the most the policy pays for one event or one claim.
• Aggregate: the most the policy pays for all claims in a policy year. See Professional Liability limits explained.
• When coverage applies: General Liability is usually occurrence, meaning it covers events that happen during the policy year. Professional Liability is almost always claims-made, meaning the claim must be made and reported while the policy is active. It also only covers work done after its retroactive date, the earliest work date it will cover. See claims-made vs occurrence.
• Separate limits: a General Liability limit never counts toward a Professional Liability requirement, and the reverse is also true. Each policy needs its own limit.

Which policy would respond in a simple example?

These examples are hypothetical.

1. A General Liability claim: a marketing consultant visits a client's office and knocks over a monitor stand. A client employee is hurt and the monitor breaks. That points to General Liability.
2. A Professional Liability claim: the same consultant delivers a financial model with a formula error. The client relies on it, makes a poor decision and loses money. No one was hurt and nothing was damaged, so this points to Professional Liability.

A claim that a website you built exposed a client's data is less clear, and the outcome depends on the policy wording and the facts.

Who usually needs both General Liability and Professional Liability?

Service businesses with client contracts often do, such as:

• Consultants who meet clients in person or work on client sites
• IT and software firms, which usually buy Technology E&O (Professional Liability for tech work), often paired with cyber coverage (help with the costs of a data breach)
• Marketing, design and media agencies, which may need media liability (coverage for claims over the content you create)
• Architects and engineers (A&E), who usually buy A&E Professional Liability
• Real estate brokers, agents and property managers, who usually buy real estate E&O

Lawyers and medical providers usually buy their own malpractice forms.

How do General Liability and Professional Liability fit together?

You can buy the two as separate policies or as a package. A Business Owner's Policy (BOP) bundles General Liability with property coverage. A BOP usually does not include Professional Liability, and many exclude professional services.

Some insurers sell both coverages in one package. If it shares one limit across both, it may not meet a contract that asks for separate limits.

A commercial umbrella (extra limit that sits on top of your other policies) adds limit above General Liability, but it almost never covers Professional Liability. See does an umbrella cover Professional Liability.

What will underwriters ask for?

Underwriters (the insurer's coverage decision makers) often want:

• Your revenue, split by type of service
• How often you visit client sites
• Your client agreement and the contract that sets the requirement
• Loss runs, which are reports showing your past claims
• Your current policies, including the Professional Liability retroactive date

What affects the cost?

• Your services and the risk of client financial loss
• Your revenue and number of employees
• The limits each contract requires
• Your claims history on each policy
• Your retention, the amount you pay on a claim before the policy pays

Frequently asked questions

Does General Liability cover a mistake in my consulting work?

Usually not. Many General Liability policies exclude professional services. A claim that your work cost a client money usually needs Professional Liability.

Do I need both General Liability and Professional Liability?

Often, yes. Service businesses with client contracts may need both, and many contracts ask for each. A remote consultant who never meets clients may still be asked for General Liability by contract.

Can one certificate show both policies?

Often, yes. A certificate of insurance is a short summary of your coverage. It usually lists each policy in its own row with its own limits, but the layout depends on how your policies are written.

If I switch my Professional Liability policy, what should I watch for?

Make sure the new policy keeps your retroactive date and prior acts coverage (coverage for work you did before the new policy starts) where the market allows. Report any known incidents to your current carrier before it ends, since a new policy usually excludes matters you already knew about.
