What to Ask Before Hiring an EV Charger Installer in Chattanooga
Five questions that separate a legitimate licensed Chattanooga electrician from someone who'll cut corners and cost you the EPB rebate and Night Shift TOU benefits in the process.
Most Chattanooga electricians are straightforward and do good work. But EV charger installation has attracted some unlicensed operators who offer cheap jobs without permits. A permitted installation is required by Tennessee law, required for the EPB rebate, and protects your homeowner's insurance. These five questions take a few minutes and filter out problems before you hire.
Question 1: Are You Licensed with the Tennessee TDCI?
Tennessee requires electricians to be licensed through the Department of Commerce and Insurance (TDCI). Ask for their license number and verify it at tn.gov. A legitimate licensed electrician has this number ready immediately.
If they can't produce a license number, claim it's not required, or give you something that doesn't verify, move on.
Question 2: Will You Pull the Permit?
Ask specifically: "Will you pull the permit, and is the permit fee included in your quote?" The permit must be filed before work starts. In Chattanooga city limits, it goes through the City of Chattanooga Office of Permits and Inspection. In unincorporated Hamilton County (parts of Hixson, East Brainerd, Signal Mountain), it goes through Hamilton County Building Inspection. Your electrician should know which applies to your address.
Some installers will suggest skipping the permit. That's a mistake on multiple levels. It forfeits the EPB rebate, risks insurance coverage, and creates home sale disclosure problems. Don't accept it.
Question 3: Do You Know EPB's Rebate and Night Shift TOU Plan?
This tells you quickly whether the installer does regular EV work in the Chattanooga market. EPB's setup is specific: a $50 rebate applied for at epb.com, plus the Night Shift TOU plan (lower rates 9 PM–6 AM) that EV owners should enroll in separately.
A knowledgeable Chattanooga electrician will mention these or at least know the answers when you ask. They'll also confirm there's no charger model requirement for the EPB rebate. Any Level 2 charger qualifies. If the installer is totally unfamiliar with EPB's EV programs, they probably haven't done many Chattanooga EV installs.
Question 4: What Exactly Does Your Quote Include?
Get a written, itemized quote. A solid Chattanooga EV charger quote covers:
- Labor: Electrician's time for the full installation
- Materials: Conduit, wire, breaker, mounting hardware
- Permit fee: City of Chattanooga or Hamilton County permit
- Exclusions: Usually the charger itself; panel upgrades if needed
Ask what would cause the price to change. Chattanooga-specific variables: panel capacity in older homes, hillside or elevated lot layouts that affect conduit routing, attic access in Chattanooga's older housing stock, and detached garage distances. Get this answer before any work starts.
Question 5: Have You Installed This Specific Charger Before?
Most licensed electricians can install any Level 2 charger. But experience with your specific model matters. If you're buying a ChargePoint, JuiceBox, Emporia, or Tesla Wall Connector, ask whether they've installed that brand. If not, ask them to review the manufacturer's installation manual ahead of time.
For the EPB Night Shift rate advantage, you want a smart charger with built-in scheduling. Make sure the electrician can confirm your charger supports scheduling and knows how to set it up, or at minimum can point you toward how to configure it.
Red Flags Summary
| What They Say | What It Means |
|---|---|
| "Permits aren't required for this" | Wrong or avoiding it. Both are problems. |
| Can't provide a Tennessee TDCI license number | May not be licensed |
| Never heard of EPB's Night Shift plan | Hasn't done many Chattanooga EV installs |
| Quote is $100 to $150 all-in | Excludes materials, permit, or both |
| "You need to decide today for this price" | Pressure tactic. Walk away. |
How Many Quotes to Get
Two to three. Labor for a standard Chattanooga attached garage install runs $300 to $600. Quotes outside that range without explanation need scrutiny. See the full cost guide for current Chattanooga-area pricing.
Frequently Asked Questions
Get quotes first. Your electrician may have charger preferences based on your panel and setup. There's no ENERGY STAR requirement for the EPB rebate, so your charger options are wide. Line up your installer before you buy so you can confirm charger compatibility.
Ask them to explain what they found. A good electrician walks you through the capacity calculation. If you're uncertain, get a second opinion before agreeing to the upgrade. See the panel upgrade guide for what a legitimate panel assessment looks like.
What matters most is Tennessee TDCI licensing, familiarity with City of Chattanooga or Hamilton County permit processes, and knowledge of EPB's programs. A Nashville electrician unfamiliar with Chattanooga's permit office and EPB may have a slower process. Local experience counts for something.
A quote is a good-faith estimate. For a fixed-price job, ask for a written contract specifying the scope and price. For jobs where cost variables are uncertain, ask for a written range and what would trigger a change. Get this in writing before the job starts.
