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. [14](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [15](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [16](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [17](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## What Are the Key Differences Between Berkshire Hathaway Specialty Insurance and Marsh Professional Liability (E&O) Insurance?

### Published product classes and brokerage work

Berkshire Hathaway Specialty Insurance identifies staffing, management consulting, marketing and real-estate firms for Miscellaneous Professional Liability, plus separate law-firm size bands. Marsh places professional liability for industries including finance, law, architecture, media, technology and healthcare. Its practice describes attorneys, economists and actuaries working with coverage specialists to assess exposure. A buyer with a complex professional-services risk can compare BHSI’s named product targets with Marsh’s stated multidisciplinary placement approach, then ask which markets will consider the account. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

### Coverage boundaries

Marsh says many professional-liability policies also cover privacy violations and computer-security breaches; BHSI describes a combined form for architects, engineers and consultants that includes media, technology and cyber/network-security exposures. Neither statement means every quote includes those elements. If either exposure matters, compare the policy schedule and endorsements rather than treating broad portfolio descriptions as a commitment. [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [7](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/professional-firsttm-architects-engineers-and-consultants-professional-liability/ "Professional First Architects, Engineers and Consultants Professional Liability")

## What Should You Confirm in Berkshire Hathaway Specialty Insurance and Marsh Professional Liability (E&O) Insurance Quotes?

- Ask Marsh which insurers and professional-liability forms its team proposes for your industry. [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Ask BHSI which Professional First product matches your profession and what limit is offered. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")
- Request the wording for privacy, computer-security, media and technology extensions from both placements.
