Professional Liability Insurance — commonly called Errors & Omissions (E&O) — is the safety net that protects professionals and small firms from claims alleging negligence, errors, omissions, or failure to deliver promised services. For U.S.-based practices in cities like New York City, Los Angeles, Chicago, and Houston, an E&O policy can mean the difference between a manageable business disruption and a financially catastrophic legal claim.
This article (Core Definition & Fundamentals) explains how E&O works, shows concrete pricing examples from major carriers, and uses real-world (anonymized) case studies to illustrate how policies respond in practice.
What E&O actually covers (and what it doesn't)
- Covers: Allegations of negligent advice, design or service, breach of professional duty, and related legal defense costs and settlements.
- Does not cover: Intentional illegal acts, bodily injury/property damage (normally covered by general liability), and most medical malpractice claims (which require specific medical malpractice policies).

Typical coverage limits and costs in the U.S.
Most small businesses buy limits expressed as “$1,000,000/$1,000,000” (per claim/aggregate) or “$1M/$2M.” Costs vary widely by profession, location, revenue, and claims history.
- Small consultants, freelancers, and other low-risk professions often pay $500–$2,000 per year for a $1M/$1M policy.
- Higher-risk or larger firms (architects, engineers, IT firms with data exposure) can pay $2,000–$10,000+ per year.
- Carriers, underwriting classes, and state regulatory environments (e.g., New York vs. Texas) heavily affect pricing.

Example carrier pricing (published / advertised)
- Next Insurance (digital-first SMB carrier) advertises E&O policies for small businesses with some professions showing plans starting in the low monthly tens depending on occupation and location. See their professional liability page for estimates: https://www.nextinsurance.com/small-business-insurance/professional-liability/
- Hiscox often markets E&O for independent professionals with policies advertised from around $20–$40 per month for low-risk occupations (actual price depends on state and profession): https://www.hiscox.com/small-business-insurance/professional-liability-insurance
- The Hartford, Travelers, and CNA underwrite many professional accounts; their quoting often results in higher premiums for established firms, commonly $1,000+ per year for comprehensive $1M/$2M packages. See The Hartford’s professional liability overview: https://www.thehartford.com/business-insurance/professional-liability

Real-world (anonymized) examples — E&O in action
Case 1 — Marketing consultant, New York City
A small NYC marketing consultant delivered a campaign that allegedly missed a contractual milestone, leading the client to claim lost revenue. Legal defense costs and a settlement reached $120,000. The consultant had a $1M/$1M E&O policy; the insurer paid defense costs (~$40,000) plus a negotiated settlement of $80,000, less the policy deductible. Without E&O, the consultant personally faced ruinous litigation and a likely bankruptcy filing.
Case 2 — IT contractor, Los Angeles
An LA-based IT contractor made an error during a software update that exposed a client to a data breach (no physical damage, but business interruption). The client sued for remediation and lost sales; the claim exceeded $350,000. The contractor’s E&O (with technology/professional liability endorsement) covered legal defense and settlement negotiations. The insurer also funded vendor remediation work under a covered consent, protecting the contractor’s balance sheet.
Case 3 — Accountant, Chicago suburb
An accounting firm in the Chicago area missed a tax-filing deadline for a medium-size client, resulting in penalties and interest of $60,000 and legal claims for negligence. The firm’s professional liability policy covered the penalties and defense; the final insurer-payment was roughly $70,000 including defense costs. The firm avoided a major reputational and financial crisis because the policy handled settlement and defense.
These examples illustrate typical claim sizes for small- to mid-market professional liability claims in major U.S. cities — defense costs alone can quickly exceed six figures if a matter litigates.
Why location matters (NYC vs. Houston vs. LA vs. Chicago)
- Legal climate: Some states/cities have higher jury awards and litigation frequency — insurers price accordingly.
- Regulatory exposure: Professionals in New York often face stricter regulatory scrutiny, affecting underwriting.
- Average claim severity: High-cost urban markets (NYC, Los Angeles) tend to have higher average claim payouts due to greater economic activity and higher litigation expense.
If you practice in a high-exposure city, carriers will review your contracts, revenue by client, and risk-management practices before offering favorable pricing.
How to choose the right E&O policy for your practice
- Assess realistic exposure (typical client damages, contract values).
- Aim for at least $1M/$1M for solo practitioners; consider $1M/$2M or higher for firms and higher-risk professions.
- Confirm claims-made vs. occurrence basis (most E&O policies are claims-made — continuous coverage and retroactive dates matter).
- Review defense provisions — does the policy pay defense outside the limit or within the limit?
- Ask carriers about endorsements for cyber, data breach, or specific professional services.

Final checklist before you bind a policy
- Get multiple quotes (digital carriers like Next Insurance vs. traditional like The Hartford).
- Verify retroactive dates and prior acts coverage.
- Confirm whether your contracts require additional insured or waiver of subrogation.
- Ask about claims-handling reputation — defense quality matters as much as price.

If you operate a practice in the U.S., particularly in high-exposure cities such as New York City, Los Angeles, Chicago, or Houston, a tailored E&O policy is not just prudent — it’s an essential business protection strategy.
