Key Differences in Professional Liability (E&O) Insurance

Industry Options and Price References

The Hartford names accountants, consultants, interior designers, advertising and graphic-design agencies, technology firms and healthcare professionals among its E&O audiences. It publishes average minimum monthly premiums including $62 for standalone miscellaneous professional liability, $41 for an endorsement, $239 for architects and engineers, $38 for healthcare professionals and $146 for technology E&O. Nationwide describes E&O for service businesses but its overview does not publish product-specific premium references or limits. Buyers can use the Hartford figures to distinguish product categories, then compare actual quotes with the same limits and deductible. 8 4

Claims Trigger and Extended Reporting

The Hartford says many professional-liability policies are claims-made with a retroactive date and an extended reporting period commonly 30–60 days, with longer extensions available for added cost; some forms are occurrence-based. Nationwide’s overview describes professional E&O claims but does not state which trigger applies or whether a tail can be purchased. This changes how long after work a claim can be reported, so compare the specific form and extension in the quote. 8 4

What to Confirm in Professional Liability (E&O) Insurance Quotes

  • Ask the Hartford which product category and premium basis applies, and confirm the actual limit, deductible and retroactive date. 8
  • Ask Nationwide whether its proposed policy is claims-made or occurrence and whether an extended reporting period is available. 4
  • Compare defense costs, libel/slander and copyright-infringement wording across the issued forms. 8
