Step 3: Detailed design, grid connection and pre-construction

Grid connection application process

Some sites may require a grid upgrade to deliver EV charging. You can identify your local DNO via the Energy Networks Association (ENA) website. National Grid outlines the detailed process for applying for a grid connection. The grid connection process follows a clear sequence from early enquiry to final switch‑on. This is a summary of what they advise:
