How long does commercial EV charging installation take?

A typical installation of 4–12 Level 2 chargers at a single site takes two to four weeks from permit approval to commissioning. Panel upgrades, if required, add two to four weeks. DC fast charging installations requiring transformer upgrades may take six to ten weeks. All permits, utility notifications, and ESA inspections are managed as part of the project scope.

Clear answer, explained.

Panel upgrades, if required, add two to four weeks.

DC fast charging installations requiring transformer upgrades may take six to ten weeks. For multi-site fleet programs, installations are sequenced to minimize disruption at each location.

All permits, utility notifications, and ESA inspections are managed as part of the project scope.


Key points

What this means in practice.

  • 4–12 Level 2 chargers at a single site: two to four weeks from permit approval to commissioning
  • Panel upgrades, if required, add two to four weeks to the Level 2 installation timeline
  • DC fast charging requiring transformer upgrades: six to ten weeks from permit approval to commissioning
  • Multi-site fleet programs are sequenced to minimise disruption at each location
  • All permits, utility notifications, and ESA inspections are managed as part of the project scope
  • Pre-installation planning — electrical assessment, permit preparation, utility notification — typically runs in parallel with procurement

When this applies

Best-fit environments.

  • You are planning an EV charging deployment and need to understand the timeline before committing
  • Your facility has a specific operational deadline — fleet transition, tenant move-in, event — and you need to plan backwards from it
  • You are evaluating whether panel upgrades will be required and how they affect the overall timeline
  • You are managing a multi-site fleet program and need to understand how installations are sequenced
