What to Ask Before Hiring an EV Charger Installer in Knoxville
Five questions that separate a legitimate licensed Knoxville electrician from someone who'll cut corners — and cost you the KUB rebate in the process.
Most Knoxville electricians do good work. But EV charger installation has attracted some unlicensed operators and handymen offering cheap installs without permits. A permitted installation is required to qualify for KUB's rebate of up to $400 — and that rebate is genuinely one of the better utility EV programs in Tennessee. These five questions protect both your money and your home's electrical system.
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 contractor has their number ready and it checks out in the database.
If they can't produce a license number or wave the question off as unnecessary, move on. No amount of cheap pricing offsets the risk of unlicensed electrical work on a 240V circuit.
Question 2: Will You Pull the City of Knoxville Permit?
The permit must be pulled before work starts. Ask directly: "Will you pull the permit, and is it included in your quote?"
Some installers will offer to skip the permit to move faster or keep costs down. This is a mistake on multiple levels. Without a permit, KUB will not pay the rebate. Your homeowner's insurance may deny claims related to the electrical work. And if you sell the home, unpermitted electrical work becomes a disclosure issue. The permit costs $50 to $150 and is absolutely worth it.
Question 3: Are You Familiar with KUB's Rebate Documentation?
KUB's rebate application requires proof of purchase, proof of installation, your KUB account number, and charger details. It's a mail-in process — the form and supporting documents go to KUB at PO Box 59017, Knoxville, TN 37950 within 60 days of installation.
An electrician who's done Knoxville EV installs before knows what KUB typically needs and can give you a heads-up if anything looks like it might complicate the rebate. One nice thing about KUB's program: they don't require an ENERGY STAR certified charger. Any new Level 2 charger qualifies. A knowledgeable electrician will know this and won't steer you toward a specific model just for rebate compliance.
Question 4: What Exactly Does Your Quote Include?
Get a written, itemized quote. A solid Knoxville EV charger installation quote covers:
- Labor: The electrician's time for the full install
- Materials: Conduit, wire, breaker, boxes, mounting hardware
- Permit fee: City of Knoxville electrical permit
- What's not included: Usually the charger itself; sometimes panel upgrades if needed
Ask what would cause the price to change before the job finishes. Common variables are conduit run length, panel capacity (if unknown), and attic or wall access complexity. Getting this answer upfront prevents surprise additions to the bill.
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 — some chargers have particular mounting requirements or wiring sequences. If you're buying a ChargePoint, JuiceBox, Emporia, or Tesla Wall Connector, ask whether they've installed that brand.
Since KUB doesn't require ENERGY STAR certification, your charger options are wider than on other utility programs. You're not boxed into specific models. That said, if the electrician has strong opinions about which models install cleanly and which ones have issues, that's worth hearing.
Red Flags Summary
| What They Say | What It Means |
|---|---|
| "Permits aren't required for this type of job" | Wrong or intentionally avoiding it — both bad |
| Won't provide a Tennessee license number | May not be licensed |
| Quote is $100 to $200 all-in for a full install | Excludes materials, permit, or both |
| "This price is only good today" | Pressure tactic — walk away |
| Vague about what's included in the quote | Cost will increase before work is done |
Getting Multiple Quotes
Get two or three quotes before deciding. Labor for a straightforward Knoxville attached garage install typically runs $300 to $600. A quote significantly below that range needs an explanation — ask what's excluded. A quote significantly above it is worth asking about too, especially if the scope seems identical to other bids.

Frequently Asked Questions
Get quotes first. Your electrician may have a preferred charger based on your panel setup, or may flag compatibility issues. And since the KUB rebate starts from the installation date — not the purchase date — you have flexibility to buy the charger after you've lined up the installer.
A quote is an estimate of cost. For a fixed-price job, ask for a written contract that specifies the scope and price. For jobs where variables might change the cost (panel capacity unknown, conduit run uncertain), ask for a detailed estimate with the range and what would trigger a price change.
Ask them to show you what they found in the panel. A good electrician will explain the capacity calculation: total amps available, what's already being used, and why a new 50-amp circuit won't fit without an upgrade. If they can't explain it, get a second opinion. See the panel upgrade guide for what the assessment should look like.
Familiarity with the City of Knoxville permit process matters more than whether they're a one-person shop or a regional company. Ask whether they've pulled permits through Knoxville Codes and Building Safety before. Local experience with the permit office and KUB rebate process is a real advantage.
