What Is Professional Errors and Omissions (E&O) Insurance?

Professional E&O insurance addresses claims that a mistake in your advice or services caused a client financial loss.

What Does Professional Errors and Omissions (E&O) Insurance Cover?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. 1,2,3,4

Professional Services and Financial Loss

Ask how the quote addresses a client’s financial loss from professional services, and compare its treatment of bodily injury and property damage. 1,2,4

How It Differs From General Liability

Separate injury or property-damage exposures from allegations that professional advice or services caused a client financial loss. 1,2,3

Who Needs Professional Errors and Omissions (E&O) Insurance?

Consider professional E&O if customers pay for your advice or services and a mistake could cost them money. 4,1,3 4,1

Coverage Examples

These are examples, not coverage guarantees. Your policy terms and the facts of the claim determine what is covered.

What happened

A Client Says Your Advice Cost Them Money

A client alleges that an error in your professional advice caused a financial loss.

How coverage may help

Professional E&O may pay defense costs and covered damages. The service you provided must fit the work insured, and defense spending may reduce the limit. 1,2,3,4

What happened

An Old Project Leads to a New Claim

A former client brings a claim after you've switched insurers.

How coverage may help

Protection for earlier work depends on the retroactive date and reporting terms. An extended reporting period may help with later claims when earlier coverage ends. 1,2,3,4

How Does It Compare With Related Coverage?

Technology Errors and Omissions

Confirm whether the quote schedules professional services under professional errors and omissions (E&O) coverage, or uses a separate technology errors and omissions form for technology products or services. 4,2,5

Medical Malpractice

Medical malpractice is a specialized professional-liability product for health care; do not treat a general professional E&O quote as a substitute for it. 5,2,4

Business Owner’s Policies

Do not assume a business owner’s policy includes professional liability; check the proposed coverage and whether you need a separate policy. 2,6

How Do You Compare Coverage and Costs?

Claims-Made Timing

Ask whether the quote is claims-made, when a claim must be made and reported, and whether an occurrence form is available instead. 2,1,4

When replacing claims-made coverage, compare the retroactive date and reporting terms with your current policy. Earlier work may need to remain covered, and known circumstances must be disclosed. A new start date alone doesn't establish continuity for advice or services you delivered in the past. 4,1

If you change insurers or stop buying claims-made coverage, ask about an extended reporting period for later claims arising from earlier work. 2,4,1
Timing questionWhat to ask
Claims-made or occurrenceWhen must the claim be made and reported, and is an occurrence form available instead?
Retroactive dateDoes prior work count, and have you disclosed known circumstances that could become claims?
Changing insurers or stopping coverageIs an extended reporting period available for later claims that arise from earlier work?
2,1,4 4,1 2,4,1

Defense, Limits and Scheduled Services

Check the insurer’s duty to defend, whether defense expenses reduce the available limit, and any consent-to-settle terms. 4,1,2 Compare the each-claim limit, the aggregate limit, and the deductible or retention. 4,2 Confirm the named businesses and people insured and the professional services the quote actually schedules. 4,1

Exclusions

Ask how the quote treats bodily injury, property damage, dishonest acts, intellectual-property claims and failure to protect confidential information. 4,2

What Do You Need for a Quote?

Services and Contracts

Prepare a description of the professional services you sell, who performs them, and the clients or contracts that require proof of insurance. 4,1,3

Claims History and Current Terms

Have information on prior claims, incidents and known circumstances that could become claims ready for the discussion. 4,1 Bring current professional-liability terms, the retroactive date and any existing extended-reporting or tail arrangement. 4,1
PrepareHow to use it
Services you sell, who performs them, and contracts that require proof of insuranceMatch the scheduled services and insured names to the work you actually do.
Prior claims, incidents and known circumstances that could become claimsGive the broker a concrete history instead of a generic “no losses.”
Current professional-liability terms, retroactive date, and any extended-reporting or tail arrangementCompare continuity if you are changing insurers or stopping a claims-made policy.
4,1,3 4,1 4,1

Key Terms in Plain English

Professional Services

The work named in the quote. Confirm it matches the services you actually sell and the people providing them. 4,1

Extended Reporting Period

Extra time to report eligible claims about earlier work after claims-made coverage ends. 2,4,1

Frequently Asked Questions

Is Professional Liability Included in a BOP?

Not automatically. Check whether professional liability is included, added or quoted separately. 2,6

What if a Claim Arrives After I Stop Buying Coverage?

An extended reporting period may provide a way to report later claims about earlier work. Discuss it before ending or replacing claims-made coverage. 2,4,1

Do I Need Professional E&O if I Already Have General Liability?

The policies address different exposures. General liability concerns injury and property damage; professional E&O concerns allegations that your services or advice caused a client financial loss. Compare the actual terms before treating one as sufficient for both. 1,2,3 1,2,3,4

Can Professional E&O Cover Work Done Before the Policy Started?

It may, depending on the retroactive date and prior-work terms. Confirm those terms and disclose known circumstances that could become claims instead of assuming all earlier work is included. 4,1
