Our success in delivering highly engineered solutions in challenging environments ensures we regularly win repeat business with major clients.

We have a reputation for successfully completing technically challenging projects involving low, high and extra high voltage infrastructure and installations such as substations, cables and overhead powerlines.

We deliver capital projects and infrastructure upgrades for UK clients, such as:

  • National Grid
  • Scottish and Southern Energy
  • Southern Electric Power Distribution
  • Electricity Alliance West
  • Electricity North West


We are regarded as one of the leading underground cabling companies in the UK having delivered some of the country’s largest HV and EHV cabling projects.

Our expert in-house delivery teams provide bespoke turnkey cable system design, installation, jointing, terminating and pre-commission testing for voltages up to 400kV.

We deliver underground cabling to networks ranging from a few hundred meters in length to connections that are hundreds of kilometres long. 


Horizontal Directional Drilling (HDD)

We are a market leader in advanced underground drilling techniques, particularly Horizontal Directional Drilling (HDD).

Our in-house teams are capable of executing the largest and most complex HDD projects including those associated with energy infrastructure in the UK. 

On our recent East Anglia One Wind Farm Project we undertook topographical surveys of all drilling locations, ground investigations, calculations of duct suitability, drilling fluid pressure calculations and temporary works designs. 

We went on to deliver 163 horizontally directionally drilled High Density Polyethylene (HDPE) ducts, ranging from 50m long and 32mm in diameter to 1,055m long and 800mm in diameter across 21 different locations.

This project won the UK Society of Trenchless Technology (UKSTT) Award for Best New Installation: Energy and Communications.
