Mechanical, electrical, plumbing, and fire protection contractors performing building systems installation and service.

Overview

Mechanical, Electrical & Plumbing (MEP) covers the specialty trade contractors that install and service building systems — electrical, plumbing, HVAC, and other mechanical equipment. At ~$589B across nearly 200,000 establishments, it is the largest specialty-trade segment and the single most active corner of construction for private-equity roll-ups.

Demand is driven by both new construction and the recurring service, maintenance, and retrofit of existing building systems — the recurring side (service contracts, repairs, replacements) being especially attractive. Electrification, data centers, and energy-efficiency retrofits are structural tailwinds. It is highly fragmented and consolidating fast.
