Markel Insurance, the insurance operations within Markel Group Inc., announced a strategic collaboration with Greenhouse Specialty Insurance Services to deliver environmental casualty insurance solutions for contractors and consultants: nationwide, on paper rated A (Excellent) by AM Best.

The program pairs Markel's financial strength with Greenhouse Specialty's environmental underwriting focus: general liability, contractors pollution, professional, and site pollution coverage combined in the customizable Greenhouse Package, excess capacity up to $5M through Greenhouse Excess, and a companion admitted auto product for environmental risks.

“Environmental risks present significant complexity and challenges. Leveraging Greenhouse Specialty’s experience and innovative strategies, we have developed a program that effectively addresses these exposures.”

Jeff Lamb, President of Programs, Alliances, and Insurtech, Markel

For Greenhouse, the collaboration landed roughly two months after launch: early validation of a thesis the founders had carried for years: that a boutique, relationship-first program administrator with deep environmental expertise could earn the backing of one of the industry's most respected carriers.

“We built Greenhouse Specialty to prove that doing business the right way, putting people and purpose first, can drive exceptional results.”

Josh Rubin, Co-Founder, Greenhouse Specialty

The program serves environmental, energy, and industrial contractors and consultants across all fifty states.
