EV Charger for InstaVolt - Corley Services


InstaVolt, a leading provider of EV charging infrastructure in the UK, partnered with Welcome Break to install EV charging units at Corley Northbound and Southbound M6 service stations. Sinewave supported InstaVolt as principal contractor completing the on-site installation.

The Technicals
  • 15 x 50kW Rapid Chargers
  • Directionally drilled under the service station roads for the point of connections
  • Principle Contractors
  • 100 + metres of trench work and cable installation
  • Concrete bases and all relevant infrastructure
  • All street furniture within the site
  • Creation of 15 new car-parking bays
  • Street lighting relocation
  • Tree removal
  • 120 metre access road construction to DNO substation
“Corley North is the largest EV charging hub on the UK motorway network. Working as principal contractor pulling together teams from internally, as well as others, was a challenge we relished. Delivering on time and on budget, and then seeing it become operational,”

George Dent



Serving as delivery partner at Corley Services Northbound & Southbound M6 allowed Sinewave to assume overall reasonability for the full project. To avoid disruption to the busy Welcome Break service station, Sinewave utilised directional drilling techniques to avoid road closures. The site remained open and functioning normally over the full construction period. Sinewave completed all work ahead of schedule and on budget, then performed a seamless client handover.


InstaVolt’s charging network continues to grow. Corley Services Northbound & Southbound M6 becomes one of the largest service station charging locations in the UK. And, the goal of improving accessibility to charging locations moves closer to reality.
