How to Verify a Tesla Certified Installer Before You Hire

Why verification matters for EV charger and Powerwall work

A home charger or battery system is a long-duration electrical load connected to your panel. The quality of the installation affects how reliably it works, whether it passes inspection, and whether your warranty and insurance hold up if something goes wrong.

The word "certified" is also easy to use loosely. Some companies say "Tesla-approved" or "Tesla-ready" when they simply install Tesla products. Those phrases are not the same as being part of Tesla's certified installer network, which is why a few minutes of checking is worth it.

Step 1: Ask which Tesla program the installer belongs to

Start with a direct question: "Are you a Tesla Certified Installer, and for which products?" Certification can apply to different product lines, such as Wall Connector charging or Powerwall energy storage, so ask about the specific product you want installed.

A legitimate installer can tell you how they became certified and which of their team members do the work. Vague answers, or a pivot to "we install them all the time," are a signal to keep asking.

Step 2: Confirm the listing through Tesla's official channels

Use Tesla's official website and support resources to confirm that the company appears in Tesla's installer network. Search for the company by its legal name and the area it serves, not just by a brand name used in marketing.

If you ordered your charger or Powerwall through Tesla, your order and account pages may also direct you to installers. If an installer cannot be found through any official Tesla channel and cannot explain why, treat the certification claim as unconfirmed until Tesla or the company provides proof.

You can also ask the installer to show their certification documentation. Reputable companies are used to this request.

Step 3: Verify the electrical license

Tesla certification does not replace a state or local electrical license. These are separate things, and you want both.

Licensing rules differ by state and sometimes by city, so the licensing board in your area is the authority on what is required.

• Ask for the license number of the company or the responsible electrician.
• Look that number up on your state's contractor or electrical licensing board website, which is typically public.
• Confirm that the name matches, the license is active, and it covers the type of work being done.

Step 4: Check insurance and ask for proof

Ask for a certificate of insurance showing general liability coverage, and ask whether the crew is covered by workers' compensation where required. Certificates can be requested directly from the insurer or the installer's agent, and the document should list the policy period.

This matters because work happens inside your home and on your electrical system. A licensed and insured installer protects you if property damage or an injury occurs on the job.

Step 5: Ask how permits and inspections are handled

Most charger and battery installations require a permit and an inspection from your local authority. Ask the installer:

An installer who suggests skipping the permit to save time or money is raising a serious red flag. Unpermitted electrical work can create problems with insurance claims, utility interconnection for Powerwall, and the sale of your home.

• Who pulls the permit, the installer or you?
• Will the work be inspected, and will they be present?
• Can they show examples of recently permitted work in your area?

Step 6: Expect an in-home assessment

A trustworthy quote starts with a look at your actual setup. Panel capacity, available breaker space, wire run length from the panel to the garage or wall, and the condition of existing wiring all affect what the job involves. Costs vary by those factors, so be cautious about a firm price given sight unseen with no questions asked.

A good assessment should end with a written, itemized estimate that explains what is included, such as the equipment, labor, permit fees, and any panel work if it turns out to be necessary.

Red flags to watch for

One item on this list is not always disqualifying, but several together usually mean you should look elsewhere.

• No license number offered, or a reluctance to share it.
• Certification claimed but not verifiable through any official Tesla source.
• Pressure to sign today or pay the full amount up front.
• A quote that is far lower than others with no explanation of what is left out.
• No mention of permits or inspection.
• No written warranty on workmanship.
• Reviews that are only on the company's own site, or that look copied.

How to compare quotes fairly

When you collect two or three estimates, compare scope rather than just the bottom line. Check whether each includes the same charger or battery model, the same circuit size and wiring route, permit and inspection fees, and any panel or service upgrade. Ask each installer what would cause the price to change after work begins.

Also compare workmanship warranties and who you would call if something needs service after installation.
