A General Contractor’s Perspective on your Future EV Purchase

EV Charging

As a general contractor that works in the Seacoast of New Hampshire, I have
regularly been asking customers if they are planning on purchasing an electrical vehicle in
conjunction when doing a larger remodeling project. The reason for asking this question is
that this future electrical demand of an EV Purchase should be evaluated when altering or expanding
a homeowner’s electrical Panel during a remodel.

Homeowners who have a 100-Amp Service at their home are likely going to have to
upgrade their Electrical Service to a 200-Amp service. In Dover, New Hampshire, I would
expect that the minimum service upgrade would be around $3,500.00 for a 200-Amp
Service upgrade.

If you’re a homeowner who has a larger square footage home; with luxury electrical
appliances such as hot tubs and mini-splits you may be a candidate for a 400-Amp Service.
Especially if two charging stations are installed in the garage that are level 2. I would
expect a 400-amp service upgrade to range from $5,500-$6,000.

Globally, the most common EV charging port installed is a Level 2, which is 240
Volts. Nationally, a Level 2, EV charger ranges in cost between $600-$1200, however
there are several variables that influence the final cost, including the charger type,
connection method, installation location, and what region of the country you live.

I would also recommend homeowners that are considering a stand-by generator and
a future EV purchase, expressing that desire when sizing the correct Kilowatt generator for

As you can tell, there are several factors to consider when evaluating an EV purchase.
