Professional Liability (E&O) Insurance

Protection for claims that a mistake, oversight or missed obligation in your professional services caused a client financial loss.

Professional liability, also called errors and omissions (E&O), responds to claims that your advice, design or services caused a client a financial loss. Unlike general liability, it focuses on economic harm from professional work rather than bodily injury or property damage.

Most professional liability policies are written on a claims-made basis: the policy in force when a claim is first made against you typically responds, not the one in force when you did the work. The timing rules — the retroactive date, reporting deadlines and extended reporting options — decide whether a policy can respond, so they deserve as much attention as the limit.

Forms are often built for specific professions, from consultants and technology firms to design professionals and real estate agents. We help firms across the U.S. match the form to how they actually deliver their work and what their client contracts require.

How the timing works: an example

Say your policy has a retroactive date of March 1, 2019, and it ends on June 30, 2026, when you retire. In 2027, a former client claims a mistake on a 2024 project cost them money.

If you bought an extended reporting period (often called tail coverage) when the policy ended, you can usually report that claim during the extra reporting time.
A claim about work done before March 1, 2019 usually isn't eligible, because it falls before the retroactive date.
Work you do after June 30, 2026 isn't insured by the extended reporting period — it only adds time to report claims about earlier work.

The length, cost and availability of an extended reporting period depend on the policy.

Salons, fitness and other hands-on services

"Professional liability" means different things for different occupations. Generic E&O policies for consultants and similar firms usually address financial loss from mistakes in professional services, and many exclude bodily injury.

Salons, spas, fitness instructors and similar service businesses face a different risk: a client hurt by a treatment, product or workout. Claims like these are usually addressed by professional or service liability forms written for that occupation, sometimes packaged with general liability. The appropriate form depends on the activity and the type of claim, so tell us exactly which services you provide. See also our page for retail and service businesses.

What's typically included

Exact coverage depends on the policy form, endorsements and insurance company.

Errors, omissions and negligence

Claims that a mistake, oversight or failure to perform professional services as promised caused a client financial loss.

Defense costs

Legal defense for claims within the policy's scope, even if the allegations are groundless. Whether defense costs reduce the limit depends on the policy.

Claims-made trigger

The policy in force when a claim is first made and reported typically responds, as long as the services were performed on or after the retroactive date.

Retroactive date

The earliest date your services can have been performed for a later claim to be eligible. Keeping the same retroactive date when you change insurance companies can preserve protection for prior work, often called prior acts coverage.

Extended reporting period (tail)

An option, usually chosen when a policy ends, that extends the time to report claims about services performed on or after the retroactive date and before the policy ended. It doesn't insure new work after the policy ends. Length, cost and availability depend on the policy.

Disciplinary and subpoena expenses

Some forms include sublimits — smaller limits within the policy — for responding to licensing board complaints or subpoenas related to your professional services.

Work by subcontractors

Some forms can extend to professional services performed on your behalf by independent contractors, depending on the policy wording.

What to watch for

Losing your retroactive date by switching insurance companies or letting coverage lapse, which can remove protection for past work.
Defense inside the limits, where legal costs reduce the amount left to pay a settlement or judgment.
Late reporting: claims-made policies usually require prompt notice, and notice after the policy ends may not be accepted unless an extended reporting period applies.
Contractual liability exclusions for promises beyond the normal standard of care, such as performance warranties or broad indemnity clauses.
A definition of "professional services" that doesn't match everything you do — or a bodily injury exclusion when your services can physically affect clients.
Consent-to-settle (hammer) clauses, which can shift costs to you if you turn down a settlement the insurance company recommends.

What affects price and eligibility

Profession and specific services performed, including higher-hazard work
Annual revenue and concentration in your largest clients or projects
Limits, retention and whether defense is inside or outside the limits
Claims history and any known incidents that could become claims
Contract practices such as written agreements, defined scopes and limitation-of-liability clauses
Years in business and the experience and licensing of principals

Professional Liability FAQs

What does claims-made mean?

A claims-made policy typically responds to claims first made against you and reported during the policy period, for services performed on or after the retroactive date. The policy that matters is the one in force when the claim arrives, not when the work was done.

What is tail coverage and when do I need it?

Tail coverage, or an extended reporting period, gives you extra time to report claims after a claims-made policy ends. It applies to otherwise eligible services performed on or after the retroactive date and before the policy ended — not to new work after that. It often comes up when a firm closes, sells, merges or moves to an insurance company that won't keep the prior retroactive date, and its length, cost and availability depend on the policy.

What does defense inside the limits mean?

It means defense costs reduce the limit available to pay a settlement or judgment. Defense outside the limits keeps the full limit available for damages, though availability depends on the profession and insurance company.

Doesn't general liability handle professional mistakes?

Usually not. General liability is built for bodily injury and property damage, and most forms exclude professional services. Professional liability is designed for financial loss arising from your work.

I run a salon or fitness studio. Is that the same professional liability?

Not usually. Claims from salon, spa or fitness services often involve bodily injury, which many E&O forms exclude. Forms written for those occupations address that risk differently, so tell us what services you provide and we'll discuss which type of form applies.

Should I report a potential claim before anyone sues?

Many policies allow, and some require, notice of circumstances that could lead to a claim. Reporting promptly can tie a future claim to the current policy, so ask us before your renewal or a change of insurance company.
