On a house with capacity to spare this is a straightforward half-day job. On a house without it, it becomes a conversation about the service, and the difference between those two is a load calculation rather than a guess.
Level 2 charger installation: capacity first, then distance
Two things move the number and neither is the charger. The first is whether the service can carry a continuous 40 or 48 amp load on top of everything else. The second is how far the charger sits from the panel, because that run is most of the labour, which a wall connector install shows in detail.
Where both are favourable, expect $900 to $1,800 all in, with the wider market sitting at $749 to $2,500. Hardware is $400 to $900 of that and labour $200 to $700, over two to six hours.
Where the service cannot carry it, add $800 to $3,500 for the capacity work, and that is when the honest conversation starts. An electrical panel upgrade is one answer, a subpanel another where the box is merely full, and load management is often a third that costs nothing at all.
Fresh install
How it runs
A level 2 charger install in Buffalo, four steps
Load calculation
Totals against the demand factors. This decides whether it is a half-day job or a capacity conversation.
Route and mounting
Where the charger goes and how the run gets there. Distance from the panel is most of the labour.
Install and commission
Circuit run, unit mounted and hardwired or landed on a dedicated receptacle, then tested at full rate.
Inspection and paperwork
Permitted work, so the inspection is booked by us and the certificate comes to you.
The option not offered
Level 2 charger installation without a panel upgrade
A charger with load management watches the rest of the house and steps back when the service is busy. Overnight, when almost nothing else is running, it charges at full rate.
That matters because a plain load calculation can say no while a managed install says yes, and the difference is thousands of dollars. Any quote that jumps straight to a service upgrade without mentioning it is worth a second opinion, which is the point of the EV charging overview.
Hardwired against plug-in is the other decision. Hardwiring is required above a certain rating and is generally the tidier answer outdoors; a plug-in unit is easier to take with you.
Where the outlet is the route chosen, outlet and switch installation covers what a dedicated high-amperage receptacle needs. Whichever way it goes, this is permitted work, and permits and certificates sets out what that produces and who ends up holding it.
$900 to $1,800 all in where the service already has room, with the wider market at $749 to $2,500. Add $800 to $3,500 if capacity work is needed. Example ranges, not quotes.
Often not. Load management lets a charger step back when the house is busy, and that frequently turns a no into a yes without touching the service at all.
Hardwiring is required above a certain rating and is tidier outdoors. A plug-in unit is easier to take with you if you move. Both are fine below that threshold.
Two to six in most cases, driven by how far the charger sits from the panel rather than by the unit itself.
Yes, and most people do. Send us the model beforehand so the right breaker and cable are on the van the first time.
Further than most people expect, but distance costs. Voltage drop over a long run means heavier cable, and the cable is usually the largest single line on the quote.
