Transmission and Distribution

We deliver specialist civil and underground infrastructure that supports the transmission and distribution of energy, enabling resilient connections between generation assets, substations and end users. Our capability spans high-voltage transmission corridors, substations, utility diversions and underground service routes, delivered within complex operational and regulatory environments.

Our works include the construction of foundations, duct banks, cable corridors, sea outfalls, trenchless crossings, tunnels and HDD drives, alongside all associated enabling works. These projects frequently require careful coordination with existing utility networks and operational infrastructure, where asset protection, sequencing and stakeholder engagement are critical to maintaining continuity of supply.

We have proven experience delivering large-scale trenchless solutions for energy infrastructure, including works associated with the Dogger Bank Wind Farm, where we installed HDD infrastructure supporting the world’s largest offshore wind development. This project demonstrates our ability to deliver precision underground works in support of nationally significant renewable energy schemes, managing ground risk, environmental sensitivity and programme constraints.

Sustainability sits at the core of our energy sector delivery. We actively pursue lower-carbon construction methodologies, efficient plant utilisation and innovative design approaches that reduce environmental impact without compromising safety or quality. Our recent accreditation to ISO 50001 Energy Management reflects our commitment to structured energy performance improvement, both within our operations and across the projects we deliver.

We continuously trial and implement innovative methods, materials and tools to improve efficiency and reduce embodied and operational carbon. From optimised trenchless alignments to reduced surface disruption and efficient spoil management, our solutions are designed to support the transition to cleaner and more resilient energy networks.

By combining engineering-led planning, trenchless expertise and a strong sustainability focus, we provide a trusted transmission and distribution capability, supporting the delivery of critical energy infrastructure across the UK and international markets.
