Civil engineering built for power infrastructure
Heighway Construction delivers specialist civil engineering and groundworks for the UK’s energy sector. From HV compound construction to complex ducting, structural foundations and access roads, we manage every civil component that underpins high-voltage infrastructure.
Our teams work across substations, transmission sites, and distribution networks – combining sector-specific knowledge with precise execution. With a strong focus on quality, safety, and coordination, we help major utility projects move from plan to ground with clarity and confidence.
What we deliver
Our work supports the full lifecycle of power transmission and distribution infrastructure, including:
Site preparation, excavation and trenching
Foundation systems and concrete works
HV substation civils and compound construction
Ducting, drainage and utility diversions
Temporary and permanent access roads
Environmental reinstatement and landscaping
Electrical cable pulling
We work closely with principal contractors, network operators, and DNOs to meet all civil engineering requirements with compliance and reliability.
Civil works you can rely on
Our in-house engineers and site teams understand the strict tolerances and safety requirements involved in HV projects. From preparing new grid connections to upgrading live substations, our work is structured to avoid delays and minimise risk.
Coordinated sequencing with electrical and M&E works
Full compliance with CDM and site safety regulations
Accurate setting out and as-built documentation
Collaboration with National Grid and IDNO/DNOs
Environmental protection and restoration measures
A dynamic, joined-up delivery model
As part of the Heighway Group, our Construction division works in sync with other internal teams – including Mechanical and Electrical installation (Heighway Energy) and Plant operations. It’s a joined-up delivery model that allows us to mobilise faster, stay agile on site, and maintain accountability across every stage.
