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

### Different professional audiences

Berkshire Hathaway Specialty Insurance’s Professional First overview names Lawyers Professional Liability and Miscellaneous Professional Liability alongside Technology E&O and Media Liability. Liberty Mutual’s specialty-program portfolio identifies a Physicians & Surgeons Professional program marked “PL Only.” A law firm, technology service business or medical practice therefore should not assume these listings address the same professional class; start by matching your occupation to the named program before reviewing policy terms. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") [10](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

### Program access and terms

Liberty Mutual says its specialty programs are managed by program administrators and provides inquiry details, whereas BHSI presents Professional First as a portfolio with class-specific products and target segments. Neither catalogue excerpt by itself gives the form, limit or exclusions for your quote. Ask the program contact or BHSI underwriter to identify the issuing entity and attach the applicable wording so you can compare the protection that would actually be offered. [10](https://business.libertymutual.com/commercial-solutions/programs/ "Programs") [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

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

- For Liberty Mutual, confirm whether the Physicians & Surgeons program fits your specialty and request its form, limits and exclusions. [10](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")
- For BHSI, identify the applicable Professional First product for your profession rather than relying on the portfolio list. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")
- Ask both contacts who administers the program and which insurer issues your specific policy. [10](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")
