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

Named targets and specialist lines

Berkshire Hathaway Specialty Insurance names staffing firms, management consultants, marketing firms and real-estate firms as Miscellaneous Professional Liability targets, while its overview separately lists law-firm size bands. Marsh McLennan Agency describes E&O placement across specialist lines including architects and engineers and lawyers professional liability, rather than presenting them as one form. If your business crosses professional categories, the distinction affects which application and wording you should request from either source. [3] [6]

Placement and actual policy terms

Marsh McLennan Agency invites organizations to work with an adviser or specialist; BHSI’s overview describes a portfolio with several product types. Neither overview establishes your final coverage, limits or availability. BHSI’s architects, engineers and consultants form includes other exposures alongside professional liability, so confirm whether that combined form is relevant before comparing it with an MMA placement for a single professional line. [6] [1]

  • Ask MMA which specialist line and carrier it would approach for your profession. [6]
  • Ask BHSI for the exact form and whether its combined design-industry coverage applies to your services. [1]
