How to choose an EV charger installer: questions to ask, red flags to avoid
Choosing an EV charger installer is more than finding the cheapest quote. This guide covers licensing requirements, permit questions, what to ask before signing, and red flags that predict a poor installation.

Why installer quality matters more than charger brand
The charger hardware — Chargepoint, Enel X, Tesla Wall Connector, Grizzl-E — is relatively standardized and reliable. The installation is where problems happen: an undersized wire run, a breaker that trips under load, a panel connection that passes inspection but runs hot over time, or a permit that was never pulled. A poor installation can void your EV charger warranty, fail a home inspection when you sell, or in worst cases create a fire hazard. The $200 you save by hiring an unlicensed installer is not worth the risk.
Licensing and certification: minimum requirements
At minimum, your installer must be a licensed electrical contractor in your state — not just a handyman or general contractor who 'does electrical work.' Ask for their electrical contractor license number and verify it on your state licensing board's website (most have online lookup tools). EV-specific certification is a bonus, not a requirement — EVITP (Electric Vehicle Infrastructure Training Program) certification indicates the electrician has formal EV charging training, but a well-qualified licensed electrician without EVITP certification is better than a poorly qualified one who has it.
- ·Required: state electrical contractor license — verify it before signing
- ·Optional but valuable: EVITP certification (evitp.com to verify)
- ·Do NOT use a general contractor who subcontracts electrical without disclosing who does the work
- ·Ask for proof of general liability and workers compensation insurance
Permit questions every installer should answer confidently
In most jurisdictions, a permit is required to install a new 240V circuit for an EV charger. Ask your installer directly: will you pull a permit for this job? A permit-included installation means the work gets inspected by your local building department — that inspection protects you. An installer who says permits 'aren't necessary' or tries to talk you out of pulling one is a red flag. The inspection typically takes 15–30 minutes and happens after installation. Without it, you may face issues when selling your home or making an insurance claim.
- ·Permit required: most jurisdictions for a new 240V circuit — confirm locally
- ·Red flag: installer says permit 'isn't necessary' or offers to skip it for a discount
- ·Inspection: happens after installation, usually same week as permit request
- ·Permit cost: $50–$200, typically included in installer quote
Questions to ask before signing any quote
Get at least 3 quotes and ask each installer the same set of questions. A confident, detailed answer to all of these is a good sign. Vague or dismissive answers to any of them should give you pause.
- ·Are you a licensed electrical contractor in this state? (Ask for license number)
- ·Will you pull a permit for this installation?
- ·Is the permit fee included in this quote?
- ·Who specifically will do the work — you or a subcontractor?
- ·What gauge wire will you run, and how long is the run?
- ·Will you install a dedicated circuit or share with another load? (Dedicated is correct)
- ·Do you warranty the installation labor separately from the charger warranty?
Red flags that predict a poor installation
Walk away if an installer: refuses to pull a permit or says permits aren't required in your area without checking local code (they often are), offers a price dramatically below other quotes without explaining why, can't name the wire gauge they'll use for your run length, wants to share the circuit with an existing load like a dryer or HVAC, or can't provide a license number when asked. Price is a poor proxy for quality in electrical work — the cheapest quote often reflects cut corners on wire gauge, conduit quality, or permit avoidance that will cost more to fix later.
- ·Red flag: 'we don't need a permit for this' without checking local code
- ·Red flag: quote is 50%+ lower than others with no explanation
- ·Red flag: can't name wire gauge (10 AWG for 30A, 8 AWG for 40–50A runs)
- ·Red flag: proposes sharing circuit with an existing 240V appliance
- ·Red flag: won't provide license number when asked directly
Best Level 2 home chargers
Installing a Level 2 charger is the biggest convenience upgrade in EV ownership — full battery every morning.
Most homes do best with a 40–48 A charger on a dedicated 240 V circuit, but the right pick depends on your panel, connector type, and whether you want smart scheduling for off-peak utility rates.
Wi-Fi, app control, works with any EV. Most flexible amperage (16–50 A).
40 A / 240 V, UL certified, metal enclosure — no-frills workhorse.
Native NACS connector, up to 48 A. Best-in-class for any Tesla.
Plugs into 240 V dryer outlet — no install needed, take it anywhere.
Budget $800–$1,500 installed for many Level 2 setups. A short wiring run from a modern panel can be less, while older homes, long conduit runs, permits, trenching, or panel upgrades can push the project higher.
Before buying hardware, ask your electrician whether your home supports a plug-in NEMA 14-50 unit or should use a hardwired charger. Hardwired installs are often cleaner outdoors and can support higher amperage.
