Mechanical Design & Installation

Looking at the market: Many regional contractors talk about scale and growth. Our focus is different: delivering right first-time mechanical installation with clear communication, predictable programmes and clean handovers. Clients choose Evans for local accountability, accredited quality, and integrated BMS/control expertise built into the core of our mechanical delivery.

Why choose Evans for your mechanical installation?

• End‑to‑end delivery: Design, install, test, commission, train and maintain—all under one roof.
• Sector expertise: New build, refurb, fit‑out and live environments.
• Programme certainty: Phased works, early risk‑reduction and responsive local teams to keep handovers on track.
• Controls integrated from day one: In‑house BMS design, panel build and commissioning to de‑risk interfaces.
• Proven in specialist environments: Cleanrooms, laboratories, healthcare and server rooms with N+1 resilience.

Core keyword focus: We handle full‑scope mechanical installation – from LTHW heating, ventilation and air conditioning to domestic water, above‑ground drainage, BMS/controls, sprinklers, insulation, and specialist lab systems.
