Insurance Curator Professional Liability Insurance (Errors & Omissions or E&O) is often the single most important policy a consultant in the United States can buy. This guide explains what E&O covers for consultants, realistic limits and pricing, and contract clauses that matter when you're negotiating client agreements in markets such as New York City, San Francisco, Los Angeles, Chicago, Dallas and Houston.
What E&O (Professional Liability) Covers — and What It Doesn't
E&O insurance protects consultants against claims that allege:
- Negligent advice, missed deadlines, design errors or incomplete deliverables
- Breach of contract tied to professional services (when alleged to be negligent)
- Failure to deliver expected results, scope creep disputes, and misrepresentation of services
E&O typically does NOT cover:
- Intentional wrongdoing or fraudulent acts
- Bodily injury/property damage (that’s General Liability)
- Employee-related claims (employment practices liability is separate)
- Contractual liabilities that are beyond the insurer’s willingness to defend (unless negotiated)
Understanding exclusions up front reduces surprises when a claim emerges.
Claims-Made vs. Occurrence Policies
Most consultant E&O policies in the U.S. are written on a claims-made basis:
- A claim is covered only if the policy in force (or its tail/retroactive date) covers the time the services were performed and the claim was first reported during the policy period (or an extended reporting period).
- When you switch insurers, avoid gaps in retroactive dates and consider purchasing a tail (extended reporting period) if you are canceling or switching from a claims-made policy.
Recommended Limits by Consultant Type
- Independent solo consultants / freelancers: $1M per occurrence / $1M aggregate (commonly written as $1M/$1M)
- Small consulting firms working with mid-market clients: $2M/$2M
- Consultants handling sensitive client systems/data, or with large enterprise contracts: $3M–$5M+
Why these numbers? Many clients now require a minimum of $1M/$1M for contractors; enterprise contracts often require $2M+ and may ask for higher limits with low caps on vendor liability.
Typical Cost Ranges (USA) — Real Examples
Annual premiums vary by revenue, services, claims history, and location. Below are typical starting ranges and examples from insurers active in the U.S. market:
| Insurer | Typical Starting Pricing (U.S.) | Common Entry Limit |
|---|---|---|
| Next Insurance | From roughly $20–$50/month for many small consultants (≈ $240–$600/yr) | $1M/$1M |
| Hiscox | Individual quotes often start around $300–$600/year for consultants with modest revenue | $1M/$1M |
| Insureon (marketplace) | Small consultant policies commonly $300–$1,200/year depending on practice area and revenue | $1M/$1M – $2M/$2M |

Note: Quotes depend heavily on yearly revenues, whether you store client data, contract indemnity obligations, prior claims and the states where you operate (NY/CA can push premiums higher due to claim severity).
Choosing Limits & Deductibles — Practical Rules
- Start with $1M/$1M if your annual revenue is under $250k and clients only require basic coverage.
- Upgrade to $2M/$2M when you start engaging enterprise clients, handling regulated data, or when contract language includes large indemnity clauses.
- Choose a deductible you can comfortably pay out of pocket — common deductibles range from $0–$5,000 for smaller firms. Lower deductibles usually increase premium.
Contract Clauses That Affect Coverage — What to Watch For
Insurers often deny coverage if the contract pushes the vendor beyond what the policy will cover. Before signing:
- Indemnity Clause: Avoid broad, unlimited indemnities. Negotiate to limit indemnity to claims arising from your negligence or willful misconduct.
- Hold Harmless / Duty to Defend: Try to avoid an obligation to defend the client. If unavoidable, limit duty to defend to claims arising from your negligence.
- Limitation of Liability (LoL): Push for a mutual LoL or a cap tied to the contract value (e.g., fees paid under the contract) instead of open-ended exposure.
- Additional Insured: Clients often require “additional insured” status — many E&O policies do not grant that easily. Negotiate scope and ensure your insurer will endorse the client if required.
- Waiver of Subrogation: If required, confirm your insurer will accept a waiver; often acceptable for small amounts but can increase premium or be declined for high-risk exposures.
- Cyber/Data Breach: If you handle client data or run SaaS tools, E&O alone may not cover data breach. Add cyber/privacy liability coverage or a technology E&O endorsement.
Always submit proposed client contracts to your broker or insurer for a “pre-review” to confirm coverage and reduce the chance of a claim denial.
State-Specific Notes (U.S.)
- California & New York: Higher claim frequency and defense costs — expect slightly higher premiums and stricter underwriting when you operate primarily in these states.
- Texas & Florida: Watch for contract enforcement nuances and statutory caps on certain liabilities (varies by claim type).
- Interstate Work: If you contract nationwide, ensure your policy’s territory clause covers all states where you deliver services or where clients are located.
How to Buy — Practical Checklist
- Prepare revenue figures, service descriptions, past claims history, and standard contract templates.
- Compare online insurers (Next Insurance, Hiscox) for speed and competitive pricing; use a broker for complex risks or enterprise-level contracts.
- Request endorsements for client-required language (additional insured, primary/non-contributory, waiver of subrogation).
- Reassess limits annually when revenue, client base or contract requirements change.
Quick Comparison — When to Use Which Vendor
| Best For | Example Vendor | Why |
|---|---|---|
| Fast, digital quotes for solo consultants | Next Insurance | Competitive entry pricing, easy online bind & download COI |
| Niche, boutique protection & tailored endorsements | Hiscox | Focus on small firms and flexible endorsements |
| Marketplace & multiple carriers for complex risks | Insureon | Aggregates carriers, useful if you have prior claims |
Final Contract Negotiation Tips
- Get the insurer to confirm in writing that a contract requirement is covered before signing.
- Add an explicit carve-out that the insurer must consent to any indemnity wording that broadens coverage.
- If a client insists on very broad indemnities, seek project-specific excess or umbrella limits to bridge the gap.
- When dealing with large enterprises (San Francisco tech, NYC financial services), budget for higher limits and tailored endorsements — negotiating limits is often easier if you demonstrate risk controls and documented processes.
