Chubb vs 
The Hartford Professional Liability (E&O) Insurance
The Hartford publishes average minimum premiums by product; Chubb's Pro ERM page states only 100% worldwide defense-cost coverage.
What Is Chubb?
Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company. 1,2,3
What Is The Hartford?
The Hartford is the brand of The Hartford Insurance Group, Inc., whose subsidiaries underwrite property-and-casualty insurance and employee benefits. Small-business buyers can start online or by phone or work through independent agents, while the issuing company and state eligibility still have to be confirmed on a quote. 5,6,7
What Is Professional Errors and Omissions (E&O) Insurance?
Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. 9,10,11,12
Key Differences in Professional Liability (E&O) Insurance
Published Pricing
Chubb's Pro ERM page states only that defense costs are covered 100% worldwide, without a comparable premium table. The Hartford instead breaks out pricing by product on its professional liability page:
The Hartford publishes average minimum monthly premiums by product: Misc. Professional Liability Standalone $62, Misc. Professional Liability Endorsement $41, Architects and Engineers Professional Liability $239, Healthcare Professionals Professional Liability $38, and Errors & Omissions Insurance for Technology Companies $146. The page does not publish standard coverage limits or retentions; cost and limits are set at quote. 8Company-reported. Company-reported pricing as of 2026-09-23 (page last updated by The Hartford May 4, 2026); premiums are not coverage limits.
Bundled Cover Versus Separate Products by Profession
Chubb's Pro ERM combines professional liability with media and cyber exposures in one policy for non-licensed professional-services firms. The Hartford instead sells professional liability as separate standalone products, including a miscellaneous professional liability standalone policy, an endorsement version, and named lines for architects and engineers, healthcare professionals, and technology companies. 3 8
Policy Trigger
The reviewed Chubb page does not state whether Pro ERM is written on a claims-made or occurrence basis. The Hartford says many of its professional liability policies are claims-made with a retroactive date and an extended reporting period typically 30 to 60 days, extendable to a year or more for an added cost, though some are written on an occurrence basis. 8
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Chubb for the Pro ERM liability limit and retention, since only worldwide defense-cost coverage is published. 3
- Ask The Hartford whether your specific profession's product is claims-made or occurrence, and what extended reporting period it includes. 8
- Confirm which named Hartford product matches your business, since it sells separate policies by profession rather than one bundled form. 8
- Ask Chubb whether your business fits its non-licensed professional-services eligibility for Pro ERM. 3
