## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Coverage and quote access

Gallagher arranges E&O with partner carriers for small businesses providing services, including technology, accounting, tax and legal work. It describes protection for negligence, copyright infringement and claims involving past work or contractors, and offers an online quote form, adviser phone line or callback. Markel describes miscellaneous E&O for targeted industries and states a $2 million maximum, while its reviewed page does not detail the same quote channels. A buyer can weigh Gallagher's listed contact options against Markel's stated cap and actual form. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [9](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

### Market conditions and underwriting

Gallagher says E&O insurers have become more selective and request more underwriting information, with rate increases beginning to moderate. Markel's reviewed claim gives a target revenue scope up to $5 million but does not discuss current underwriting conditions. Prepare service descriptions, claims history and revenue details before comparing offers. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [9](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

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

- Ask Gallagher which partner carrier will issue the policy and whether past work, contractors and copyright allegations are included.
- Ask Markel for appetite, limits and quote requirements for your profession and revenue.
