Professional Liability Insurance

Also known as errors and omissions (E&O) — protection against claims that your professional advice, services, or work caused a client financial harm.

  • Liability coverage
  • Common across 6+ industries

What this coverage is

Professional liability insurance, often called errors and omissions (E&O), helps respond when a client alleges that your professional services, advice, or work were negligent, contained errors, or failed to deliver as promised, resulting in financial loss.

Unlike general liability, which focuses on physical injury and property damage, professional liability addresses the economic harm that can flow from professional mistakes. These policies are commonly written on a claims-made basis, so timing and continuous coverage matter.

Who commonly needs it

Businesses and individuals who provide expertise, advice, or specialized services for a fee commonly carry professional liability. Many client contracts specifically require it.

Where this coverage commonly fits

Contract-driven — coverage that is often required by contracts, clients, landlords, or lenders. Professional liability commonly fits service and advice businesses, and client contracts frequently require it.

  • Consultants and agencies
  • Technology and software providers
  • Accountants, financial professionals, and advisors
  • Healthcare and allied-health providers
  • Architects, engineers, and design firms

What it may cover

  • Claims of professional negligence, errors, or omissions
  • Failure to deliver promised professional services
  • Defense costs for covered claims, subject to policy terms
  • Certain claims arising from work performed before the claim, within the policy period
  • Settlements or judgments up to selected limits

What it typically excludes

  • Bodily injury and property damage, which general liability addresses
  • Intentional, fraudulent, or criminal acts
  • Claims known before the policy began
  • Employment-related disputes, which EPLI addresses
  • Cyber incidents, which cyber liability addresses

Hypothetical claim scenarios

These illustrative examples are for general understanding only. Coverage depends on the specific policy terms, conditions, and exclusions.

Missed deadline causes loss

A consultant misses a critical filing deadline and the client alleges financial harm. Professional liability may help respond to the claim and defense costs, subject to policy terms.

Software error

A client says a software provider's error disrupted operations and caused losses. The policy may help address the negligence allegation, subject to terms and exclusions.

Design oversight

A design firm is accused of an oversight that required costly rework. E&O coverage may help respond to the resulting professional-liability claim.

What commonly affects cost

  • Profession and the complexity of your services
  • Annual revenue and client contract sizes
  • Claims history and risk-management practices
  • Selected limits, deductibles, and retroactive date
  • Whether coverage is claims-made and continuously maintained

How much does it cost?

On average, many businesses pay roughly $500–$2,000 per year for many small firms for professional liability insurance. That figure is a general national average only — your actual premium is set during underwriting.

Frequently asked questions

What is the difference between E&O and general liability?

General liability commonly addresses physical injury and property damage, while professional liability (E&O) addresses financial harm from alleged mistakes, negligence, or failure to perform professional services.

What does claims-made mean?

Claims-made policies generally cover claims that are both made and reported while the policy is active, subject to the retroactive date. Maintaining continuous coverage helps avoid gaps.

Who commonly needs professional liability?

Consultants, technology firms, financial and healthcare professionals, and design firms commonly carry it, and many clients require it by contract.

Does it cover intentional wrongdoing?

No. Intentional, fraudulent, or criminal acts are generally excluded. Coverage focuses on alleged negligence and errors in professional services.

What is a retroactive date?

The retroactive date sets how far back covered work can reach. Work performed before that date is generally not covered, which is why continuous coverage matters.
