Process
How long does an EV charger installation take?
The wiring is a morning's work. Everything that makes it take three weeks happens before and after the electrician is in your garage.

Two answers to this question are both true: half a day, and a month. The first is time on site; the second is time from deciding to charging. Knowing which stages are slow lets you start them earlier.
Stage by stage
| Stage | What happens | What makes it slow |
|---|---|---|
| Quotes | Site visit or photos, load calculation | Getting two or three electricians to respond |
| Permit | Application to the local authority | Jurisdictions differ enormously |
| Scheduling | A slot in the electrician's calendar | Busy seasons, and popular installers book out |
| Installation | Breaker, run, mount, terminate, test | Distance, wall type, attic and crawlspace access |
| Inspection | The inspector signs off the work | Scheduling, and any corrections |
| Utility step | Only where a program or meter change applies | Utility timelines are their own thing |
What actually happens on the day
- Power off at the panel, and the new breaker goes in.
- The run is pulled from the panel to the charger position, through walls, an attic or conduit.
- The charger or receptacle is mounted and terminated.
- Everything is tested: voltage, polarity, ground, and a live charge with your car.
- Clean-up and a walkthrough, including how to set the charging current.
For an attached garage with the panel on a shared wall, that is a short morning. The same list in a finished basement with a long fished run is a full day.
What makes it take longer
- Panel work. A service or panel upgrade is its own day, with the power off for much of it. Panel upgrades.
- A detached garage. Trenching and a feeder is a multi-day job in most yards. Detached garages.
- Finished walls. Fishing cable through drywall without damage is slow, careful work.
- Outdoor runs. Conduit, weatherproofing and depth requirements all add time. Outdoor installation.
- Waiting on parts. The charger, a specific breaker, or a receptacle that has to be ordered.
How to keep it short
- Send photos with the quote request -- the panel label, the open panel, the parking spot and the proposed wall.
- Pick the charger before the visit, so the electrician sizes the circuit once. How many amps you need.
- Ask whether the permit is handled for you. Most electricians do it; confirm rather than assume.
- Clear the space around the panel and the wall before they arrive.
- Be home for the walkthrough, so the current setting and the app are sorted while somebody who knows the unit is standing there.
Who schedules the inspection
On most jobs the electrician pulls the permit and books the inspection, and the inspector visits after the work is finished. You can normally use the charger in the meantime, but confirm that with whoever pulled the permit rather than assuming it. If a correction is required, it is usually small and the second visit is short.
The fast case and the slow case
| Fast | Slow | |
|---|---|---|
| Panel | Room and capacity to spare | Full, or a failed load calculation |
| Run | Short, through an unfinished wall | Long, fished through finished rooms |
| Location | Attached garage | Detached building, or outdoors |
| Permit | Handled by the electrician, routine | A jurisdiction with its own timetable |
| Charger | In your hands before the visit | On order, arriving whenever |
| On-site time | A few hours | A day, or two visits |
What to do while you wait
- Use the cordset that came with the car. Level 1 covers a surprising amount of daily driving overnight. Level 1 charging.
- Decide where the charger goes, properly, with the car parked where it lives. Where to mount.
- Read your car's onboard charger rating, so the amperage decision is already made when the electrician asks.
- Check whether your utility has a program worth enrolling in before the work is done. Time-of-use charging.
One last thing worth planning for: the first charge. Watch it start before the electrician leaves. A fault that shows up on the first session is far cheaper to fix while the van is still outside. If it will not charge.
