The reviewed WTW sources do not identify an issuing insurer for a specific professional errors omissions placement. 12,11,10Not publicly disclosed.

Who It’s For

Coverage Features

Product page coverage description; the issued policy and its exclusions control. Note this record excludes medical malpractice, which the page treats as a separate specialized coverage covered under its own line.

Gallagher's small-business team says the E&O market has seen consistent rate increases that have started to moderate, driven by higher claim frequency, litigation costs and a more litigious environment, and that insurers are more selective and require more detailed underwriting information. 6Company-reported. Product page market-commentary section; a general market view, not a quote for any specific business.

WTW's FY2024 annual report describes professional-liability solutions within FINEX; its residential practice lists errors-and-omissions among financial lines for residential real-estate stakeholders. 11,10Company-reported.
