Civil Engineering Works

Get Started

Our mechanical teams bring heat networks to life. We install pre-insulated steel pipework, flexible pipe systems and all associated plant and equipment. With coded welders, rigorous pressure testing and full traceability of materials, we ensure every joint and connection performs reliably for decades. From energy centre plant through to individual hydraulic interface units, we handle the complete mechanical scope.

Mechanical Installation

Get Started

We add value from the earliest project stages. Our design capability covers feasibility studies, hydraulic modelling, route optimisation and detailed construction drawings. We work with industry-standard software and integrate seamlessly with your existing design team or BIM environment. Need support with funding applications? We provide the technical input to strengthen your case.

Design & Consultancy

Get Started

Energy centres are the heart of any district heating scheme. We provide the civil and building works needed to house your generation plant, including groundworks, foundations, structural frames and building envelopes. We coordinate closely with M&E contractors to ensure smooth plant installation and commissioning, delivering facilities that are built to perform.
