Insurance Curator Professional Liability Insurance—commonly called Errors & Omissions (E&O) insurance—is a specialized policy that protects professionals and their businesses from claims alleging negligent acts, errors, omissions, or failure to deliver services as promised. For U.S.-based professionals, E&O is often the difference between keeping a practice open after a lawsuit and facing crippling legal and settlement costs.
Why E&O Matters for U.S. Professionals
Professional services are judged not just by outcomes but by expectations. When a client claims financial loss due to your guidance, design, or deliverable, a professional liability claim can allege:
- Negligence or failure to meet professional standards
- Misrepresentation or breach of contract terms related to professional services
- Omitted or incorrect advice that caused client losses
E&O focuses on financial harm caused by professional services—not property damage or bodily injury (that’s general liability).
Core Coverage Components
Typical E&O policies for U.S. professionals include:
- Defense costs (attorney fees, court costs) — often the largest expense
- Settlements and judgments (up to policy limits)
- Claims-made vs. occurrence coverage trigger rules (see next section)
- Rectification and mitigation costs in some policies
Common exclusions:
- Intentional illegal acts or fraud
- Known claims or circumstances at policy inception
- Employee dishonesty (typically covered under separate fidelity bonds)
Claims-Made vs. Occurrence: Know the Trigger
Understanding the coverage trigger is essential:
- Claims-made: Policy in force when the claim is reported to the insurer covers the claim. Most E&O policies are claims-made. Prior acts coverage (retroactive date) and extended reporting periods (tail coverage) matter a lot.
- Occurrence: Pays for incidents that occur during the policy period, regardless of when reported. Rare for professional liability.
For U.S. professionals switching insurers, buying tail coverage (or a nose policy from new insurer) is a must to avoid coverage gaps.
Who Needs E&O? (Short List — U.S. Examples)
While many professions should strongly consider E&O, common U.S. buyers include:
- Consultants and management advisors
- IT and software developers (including SaaS providers)
- Accountants and bookkeepers
- Architects and engineers
- Real estate brokers and appraisers
- Healthcare non-clinical providers (e.g., counselors, therapists — clinical providers often need separate malpractice policies)

Estimated annual premium ranges for a small professional firm (typical $1M/$1M policy):
| Insurer (example) | Typical U.S. annual cost (small firm) | Notes |
|---|---|---|
| Hiscox | $300 – $900 | Online-friendly underwriting; small-business focus. See Hiscox E&O product pages. |
| The Hartford | $500 – $1,200 | Broad small-business distribution, bundling with other coverages. |
| Travelers | $400 – $1,000 | Competitive in professional lines; varies by profession and state. |
| Market average (Insureon/NerdWallet synthesis) | $500 – $1,000 | Many small firms fall in this band for $1M/$1M limits. |
Actual quotes vary: a solo consultant in Dallas may pay a few hundred dollars/year, while a San Francisco software consultant with similar revenue could pay the higher end due to local claim frequency and carrying higher policy limits. For precise quotes, insurers (Hiscox, The Hartford, Travelers, CNA) offer online tools or agency consultations.

Location Matters — Examples from U.S. Cities
Legal environment, state-law factors, and claim frequency affect premiums:
- New York City, NY: generally higher premiums for financial and consulting services due to higher jury awards and litigation intensity.
- San Francisco / Silicon Valley, CA: higher for tech consultants and developers because of complexity and higher client revenue exposure.
- Chicago, IL; Houston, TX; Miami, FL: costs vary—Texas and Florida can have more favorable premium levels for some professions, but industry-specific exposures dominate.
Always get state-specific quotes: insurers rate by state and often by ZIP code.
Choosing Limits and Deductibles
Common limit structures:
- $1,000,000 per claim / $1,000,000 aggregate (standard for many small firms)
- $2,000,000 / $2,000,000 or higher for higher-risk professions or larger revenue
Higher limits increase premiums but reduce catastrophic risk. Typical deductible ranges: $0–$10,000; higher deductibles lower premium.
Buying Tips for U.S. Professionals
- Match limits to contract requirements: many clients require a minimum (often $1M).
- Check claims-made retroactive date: gaps can leave prior acts uncovered.
- Bundle other policies (general liability, cyber) for premium discounts.
- Maintain clear client contracts and documentation—reduce claim frequency and defense cost exposure.
- Compare carriers: Hiscox, The Hartford, Travelers, CNA, and regional brokers each underwrite differently.

Real-World Example (Illustrative)
A marketing consultant in Miami missed a campaign deadline. The client claimed $150,000 in lost revenue and sued for negligent service delivery. Defense costs topped $40,000 before settlement. With a $1M E&O policy, defense and settlement were covered (minus deductible); without E&O the consultant faced severe financial distress and potential bankruptcy.

Common Misconceptions
- “General liability covers professional mistakes.” False — GL covers bodily injury and property damage, not professional financial harms.
- “I’m small; I don’t need it.” False — even solo consultants and freelancers face claims; defense costs alone can be ruinous.
- “E&O will cover all disputes.” False — intentional wrongdoing, contract penalties, and some statutory fines may be excluded.
