Professional Liability Insurance (Errors & Omissions, or E&O) is the baseline risk-transfer tool for consultants and advisors who provide professional services, strategic advice, technical design, or implementation work. This article explains, with U.S.-focused details and pricing examples, what service-specific coverage typically looks like for consultants and advisors, what it excludes, and how location and provider choice affect cost and scope.
At a glance: What E&O is designed to protect
Professional Liability / E&O covers claims alleging that a consultant’s or advisor’s professional services caused a client’s financial loss. It generally covers:
- Alleged negligence, errors, omissions, or failure to deliver promised services
- Defense costs (subject to policy language — see “defense inside vs. outside limits”)
- Settlements and judgments up to the policy limit
- Claims-made incidents that occurred after the policy’s retroactive date and are reported during the policy period

Service-specific examples: What consultants and advisors should expect
E&O policies are tailored around the specific services you provide. Below are common consultant/advisor types and how E&O responds to typical exposures.
Management & Strategy Consultants
- Coverage focuses on allegations of faulty advice, poor recommendations, or failure to achieve projected results.
- Common claims: poor strategic guidance that results in lost revenue or failed initiatives.
- Typical limits requested: $1M/$1M or $2M/$2M.
IT, Software, and Security Consultants
- Claims often involve failed implementations, data loss, downtime, or inadequate cybersecurity measures.
- Higher exposure to defense costs and larger settlements — premiums are usually higher.
- Consider cyber E&O endorsements or separate cyber liability; E&O alone may not cover data breach regulatory fines.
Marketing, Branding, and Creative Consultants
- Typical claims: missed deliverables, misrepresentation of campaign performance, copyright infringement (often excluded unless added).
- Lower premiums than IT, but endorsements like intellectual property coverage may be necessary.
Financial, Tax & Investment Advisors (non-licensed vs licensed)
- Licensed financial advisors are often under specialty regulatory schemes (FINRA, SEC) and require specific professional liability programs.
- Independent financial consultants (non-licensed) still face high risk due to fiduciary exposure; premiums and exclusions vary.

Key policy terms every consultant must know
- Claims-made vs. occurrence: Almost all E&O policies are claims-made — coverage is triggered when a claim is first made and reported while the policy is active (or if a prior acts retroactive date applies).
- Retroactive date: Critical for prior-acts coverage; if a claim arises from work before the retro date, it may be excluded.
- Limits of liability: Often shown as “$1M/$1M” (per claim/aggregate). Higher-risk consultants may need $2M or $5M limits.
- Defense costs: Can be paid within the limit (reducing the available limit for settlement) or outside the limit (not reducing the limit). For more on this, read: Defense Costs and Professional Liability Insurance (Errors & Omissions): Who Pays What?.
- Deductible/Retention: Typically ranges from $0 to $10,000+ depending on insurer and risk class.
Pricing reality (U.S. market examples)
Premiums vary widely by service type, revenue, employee count, claims history, and location. Typical annual ranges for small consulting firms in the U.S.:
- Low-risk consultants (marketing, HR): $400–$1,200 per year
- Mid-risk consultants (management, general IT services): $800–$2,500 per year
- High-risk consultants (cybersecurity, specialized IT, financial advisory): $1,500–$5,000+ per year
Insurance vendors and advertised starting rates:
- Hiscox advertises professional liability coverage starting at roughly $39/month for qualifying small businesses (about $468/year) depending on industry and limits: https://www.hiscox.com/small-business-insurance/professional-liability-insurance
- The Hartford shows sample small-business E&O pricing and notes that many small consulting businesses can see annual premiums in the $500–$1,500 range, varying by risk: https://www.thehartford.com/business-insurance/professional-liability
- Market analyses such as Insureon report that typical small-business E&O premiums commonly fall between about $400 and $1,500 per year for many consultants, but can rise for specialized exposures: https://www.insureon.com/small-business-insurance/professional-liability-insurance
Note: these figures are illustrative; obtain quotes for precise pricing. City and state differences (see below) will materially affect these numbers.
How location in the U.S. affects coverage and cost
Jury awards, local regulatory frameworks, litigation frequency, and state law (punitive damages caps, for example) drive regional premium differences. Examples:
- New York City / NY state: Generally higher premiums for consultants due to larger potential damages and higher litigation frequency.
- San Francisco Bay Area / Los Angeles (California): Elevated rates for IT and cybersecurity consultants because of concentration of tech businesses and larger breach-related exposures.
- Chicago / IL and Houston / Dallas (Texas): Premiums vary; Texas can be more litigious in certain sectors (e.g., energy consulting), increasing costs.
Provide city-specific quotes when applying — carriers often adjust pricing by jurisdiction.
Common exclusions and endorsements to consider
Exclusions you’ll commonly see:
- Intentional illegal acts and fraud
- Known prior acts not reported at inception
- Most policies exclude bodily injury/property damage (that’s general liability)
- Regulatory fines/penalties and punitive damages in some jurisdictions
Endorsements and add-ons to consider:
- Cyber liability / network security (often required for IT consultants)
- IP infringement endorsement (for creatives and marketers)
- Contractual liability (to cover hold-harmless agreements)
- Prior acts (retroactive date) buyback

Sample comparison table: consultant types, exposures, and typical 1M/1M premium ranges
| Consultant Type | Primary Exposure | Typical 1M/1M Annual Premium (U.S.) | Common Add-on |
|---|---|---|---|
| Marketing / Creative | Missed deliverables, IP claims | $400–$1,200 | IP infringement endorsement |
| Management / Strategy | Poor advice, failed initiatives | $600–$1,800 | Contractual liability |
| IT / Software / Security | Implementation failures, breaches | $1,200–$5,000+ | Cyber liability / tech E&O |
| Financial / Investment (non-licensed) | Fiduciary loss, inaccurate analysis | $1,500–$4,000+ | Regulatory/legal defense cover |
(Prices are indicative ranges for the U.S. market; actual quotes will vary by revenue, claims history, city, and insurer.)
Claims scenarios — what’s typically covered and what isn’t
Covered examples:
- A client sues a management consultant for a faulty rollout plan that caused lost revenue; defense + settlement covered up to policy limits.
- An IT consultant’s software update causes downtime and measurable client financial loss; E&O responds to negligence allegations.
Not covered without endorsement:
- A ransomware breach causing data loss — usually requires cyber liability.
- Intentional fraud or criminal acts.
- Bodily injury or property damage (covered by general liability, not E&O).

How to choose the right policy (practical checklist)
- Confirm the policy is claims-made and check the retroactive date.
- Decide appropriate limits (start with $1M/$1M for many consultants; increase for higher exposure).
- Ask whether defense costs are inside or outside the limits.
- Review exclusions and ask about endorsements for cyber, IP, and contractual liability.
- Shop multiple carriers (Hiscox, The Hartford, and specialty carriers) and obtain city-specific quotes. See insurer resources: Hiscox, The Hartford, Insureon (links above).
Final takeaway
For U.S.-based consultants and advisors, E&O is a business-essential policy that must be tailored to the services you provide and the jurisdictions where you operate. Premiums for small consulting firms commonly range from a few hundred to several thousand dollars per year, driven by service type, location (e.g., New York, San Francisco, Houston), and the limits you choose. Be proactive: match endorsements to your service-specific exposures (cyber for IT, IP for creatives, fiduciary protection for financial advisors) and confirm key policy mechanics like retroactive dates and defense-cost handling.
