How to Choose an EV Charger Installer (Without Getting Burned)

A bad EV charger installation doesn't just mean inconvenience. It can mean tripped breakers at 2 AM, melted wire insulation behind your drywall, a voided charger warranty, or — in the worst case — an electrical fire. The difference between a good installation and a dangerous one comes down to the person you hire.

Here's how to make sure you hire the right one.

Start With the Non-Negotiables

Before you compare prices or read reviews, make sure any installer you're considering meets these baseline requirements. These aren't preferences — they're requirements.

Valid Electrical License

This should go without saying, but: verify the license. Every state requires electricians to be licensed, but the specifics vary. Some states license at the state level; others delegate to counties or cities. Ask for the license number and verify it with your state's licensing board (most have online lookup tools).

You're looking for a master electrician or a journeyman electrician working under a master's license. An apprentice shouldn't be running your job unsupervised. A handyman, no matter how capable, is not an electrician.

Insurance

The installer needs general liability insurance and workers' compensation coverage (if they have employees). If an uninsured electrician causes damage to your home or gets injured on your property, guess who's on the hook?

Ask for a certificate of insurance. A legitimate contractor will provide one without hesitation. If they get cagey about it, move on.

Permit Pulling

A proper EV charger installation requires an electrical permit in virtually every jurisdiction. The installer should pull this permit as part of the job — it's their responsibility, not yours. The permit triggers an inspection by the local building department, which is your safety net.

Any electrician who says "we don't need a permit for this" or "permits just slow things down" is telling you they're willing to cut corners. Hard pass.

EV-Specific Experience Matters

Installing a Level 2 EV charger is not exotic electrical work, but it has nuances that a general electrician might miss. An electrician who's done 200 EV charger installations will handle the job differently than one who's doing their first.

Things an experienced EV installer handles naturally:

Continuous load derating (a 48A charger needs a 60A breaker, not a 50A)
NEC Article 625 compliance for EV-specific requirements
Load calculations that account for future electrical needs
Optimal charger placement for cable reach and daily use
Knowledge of different charger brands and their installation quirks

When you call for a quote, ask directly: "How many EV chargers have you installed?" There's no magic number, but if the answer is "this would be my first," you might want to keep looking — or at least pair that information with the rest of your evaluation.

EVITP Certification: A Strong Signal

The Electric Vehicle Infrastructure Training Program (EVITP) certifies electricians specifically for EV charger installation. It's not legally required for residential work, but it means the installer has completed coursework and passed an exam on EV-specific electrical code, safety, and best practices.

There are roughly 2,000 EVITP-certified contractors in the U.S. If one is available in your area, that's a strong point in their favor. Some utility rebate programs even require EVITP certification.

What to Ask During the Quote Process

When an installer comes out for a site assessment (and they should come out — more on that below), ask these questions:

"Will you pull a permit for this work?" The answer should be an immediate yes. If they hesitate, explain why not, or offer a discount for skipping it — walk away.

"Will you do a load calculation?" A proper installer will calculate your panel's existing load to determine whether it can handle the new EV circuit. This takes 15–30 minutes and tells you whether a panel upgrade is needed. Anyone who skips this step is guessing.

"What's your warranty on the installation?" The charger has a manufacturer's warranty, but the installation work should carry its own warranty from the contractor. A year is standard; some offer two. Get it in writing.

"What exactly is included in the quote?" The quote should be itemized or at least clearly spell out: charger cost (if they're supplying it), labor, materials, permit fee, and any additional work like panel upgrades or trenching. A vague "it'll be about two grand" is not a quote.

"How long will the installation take, and when can you schedule it?" A standard install is half a day. If a panel upgrade is needed, it might be a full day. Lead times vary — some installers can come next week, others are booked out a month.

Red Flags That Should Make You Walk Away

I've heard enough horror stories to compile a reliable list of warning signs:

No site visit before quoting. An electrician who gives you a final price over the phone without seeing your panel, your garage, and the proposed charger location is guessing. Phone estimates are fine for ballpark figures, but the binding quote should come after a site visit.

Cash-only pricing. An installer who only accepts cash (or offers a suspiciously large "cash discount") is likely not reporting the work, which usually means no permit, no insurance, and no accountability.

No written estimate. Verbal agreements are worthless when things go sideways. Get a written quote with scope of work, materials, timeline, and total cost. Every time.

Pressure to decide immediately. "This price is only good today" is a sales tactic, not a sign of a busy professional. Good electricians are busy, but they don't need high-pressure tactics to fill their schedules.

Unfamiliarity with your charger brand. If you've already purchased a specific charger and the installer has never heard of it, that's a yellow flag. They don't need to be brand experts, but basic familiarity with major brands (Tesla, ChargePoint, Grizzl-E, JuiceBox, Emporia) is expected.

No clean-up plan. Professional electricians leave your garage cleaner than they found it. Ask what they do with debris, wire scraps, and drywall dust. It's a small thing, but it tells you about their professionalism.

Get Three Quotes

This is standard advice for any contractor work, and it applies here too. Get quotes from at least three installers. This gives you:

Price comparison. You'll quickly see if someone is way out of line — high or low.
Scope validation. If two out of three say you need a panel upgrade and one says you don't, that third opinion needs scrutiny.
Gut check. You'll get a feel for who's professional, responsive, and knowledgeable versus who's just trying to fill a slot.

Don't automatically pick the cheapest quote. The lowest price often means something is being left out — maybe the permit, maybe proper materials, maybe care. The middle quote is often the sweet spot, but judge on the full picture: experience, professionalism, scope of work, and price.

A Bad Installation Is Expensive to Fix

I want to emphasize this point because it's the one that gets overlooked in the rush to save money. Fixing a botched installation costs more than doing it right the first time. Always.

An improperly sized breaker might work for months before it overheats and fails. Undersized wire buried in a wall means someone has to open that wall up to replace it. An unpermitted installation means you'll need to get it permitted retroactively (which often means partially redoing the work to meet code) when you sell the house.

I've seen homeowners pay $3,000 to fix a $1,200 installation that was done wrong. It's not worth the savings.

Where to Find Good Installers

A few resources:

ChargeInstaller directory — our whole purpose is connecting EV owners with vetted, experienced installers. Search by zip code, check ratings, and find installers who specialize in this work.
EVITP.org — search their directory for EVITP-certified contractors in your area.
Your utility's website — many utilities maintain approved contractor lists for their rebate programs.
Charger manufacturer referrals — Tesla, ChargePoint, and others maintain installer networks.
Word of mouth — if your neighbor has an EV, ask who installed their charger and whether they'd use them again.

The Short Version

Hire a licensed, insured electrician who pulls permits, has EV installation experience, provides a written quote after a site visit, and can answer your questions without getting defensive. Get three quotes. Don't pick the cheapest one by default. And remember that the installation is a one-time cost for a charger you'll use twice a day for the next decade. It's worth doing right.
