Errors & Omissions Insurance in California
Professional liability coverage for consultants, contractors & service businesses · (619) 489-3751
What Is Errors & Omissions (E&O) Insurance?
Errors and omissions (E&O) insurance — also called professional liability insurance — protects your business from claims that your professional services caused a client financial harm. If a client alleges you made a mistake, gave bad advice, or failed to deliver your services as promised, E&O covers your legal defense costs and any settlement or judgment against you. General liability insurance does NOT cover these types of claims.

How Much Does E&O Insurance Cost in California?
E&O insurance costs in California vary widely by profession. IT consultants typically pay $800–$2,000/year for $1M in coverage. Real estate agents pay $400–$1,500/year. Higher-risk professions like architects or financial advisors pay more. Ready Lane works with specialty markets to find competitive E&O rates for California businesses and professionals.
E&O vs. General Liability — What’s the Difference?
General liability (GL) covers physical injury and property damage — if someone is hurt at your office or you damage a client’s property. E&O covers financial harm from professional mistakes. Most California businesses that provide professional services need both GL and E&O. Ready Lane can bundle both policies to save on premium. Call (619) 489-3751 or get a quote below.
