Electrical work is unforgiving of shortcuts, and nearly all of it hides inside walls and panels where you will never see a mistake. So vetting an electrician isn't about judging their tool skills. It's paperwork: a license you can verify, insurance you can see, a permit that gets inspected, and a quote in writing. The twelve questions below take about ten minutes, and they're the same screening logic you'd use for any trade — this guide to what to check before hiring a contractor uses it for general work.
1. Are you licensed, and what's the license number? States license electricians, usually in tiers — an apprentice works under supervision, a journeyman is fully qualified, and a master can design work and pull permits. The company doing your job should hold the license and the insurance, even when the person at your door is their journeyman. A real license number gets offered without drama. Verify it on your state licensing board's website; the lookup is free and takes two minutes.
2. Are you insured? Two policies matter. General liability covers damage to your home if something goes wrong. Workers' compensation covers an electrician hurt on your property — without it, an injury can become your financial problem. Ask for a certificate of insurance: pros send them routinely, and anyone evasive about proof has answered the question.
3. Who will actually do the work? Sometimes the person who quotes the job never touches a wire. Employees, apprentices, and subcontractors are all normal in this trade — what matters is that the work happens under the licensed company's name, insurance, and supervision, and that you know who is coming into your house. Get a name, not a shrug.
4. Does this job need a permit, and who pulls it? Panel replacements, new circuits, service upgrades, and hot tub or EV charger circuits typically need one, though rules vary by city. Normally the electrician pulls the permit in their name and an inspector signs off at the end. That inspection is free quality control — it's protecting you. If an electrician suggests skipping the permit to save money, or asks you to pull a homeowner permit for work they're doing, end the conversation.
5. Have you done this exact job before? Specifics beat general experience. Replacing a panel is a different day than troubleshooting a dead outlet, and some older panels — certain brands from decades past are widely flagged by inspectors as fire risks — need an electrician who recognizes them on sight and tells you plainly what that means for scope and price. "I've done forty of these," with an example, is what you want to hear.
6. Will I get a written, itemized quote? In writing, with the scope spelled out: the work, the materials, and what's excluded — patching and painting after a panel swap, for instance, usually isn't included. Know whether the price is flat for the job or hourly with a cap. A verbal number for serious work is a guess you'll both remember differently.
7. What happens if you find something worse? Opening a panel or a wall sometimes reveals damage or code violations that have to be corrected before your job can proceed legally. Ask how surprises are handled. The answer you want: they stop, show you, quote the extra in writing, and wait for your approval. Work that quietly doubles on the invoice is the oldest story in home repair.
8. How does payment work? For small jobs, many electricians simply bill when the work is done. For bigger work, a modest deposit with the balance due at completion — ideally after the inspection passes — is the normal shape. Paying the full amount up front, especially in cash, removes every bit of leverage you have. If the schedule they propose front-loads most of the money, that's information.
9. What warranty do I get? Two parts: the manufacturer's warranty on the equipment, and the electrician's own warranty on their labor. Labor coverage of at least a year is common for reputable shops; some offer more. Get it in writing — a warranty that lives in a handshake expires with the conversation.
10. How long will the job take — and how long is my power off? A panel replacement usually means most of a day without power. Plan the fridge, freezer, work-from-home, and any medical equipment around that window — and get the window in advance, not at 9 a.m. on the day.
11. Do you clean up and label everything? Hauling away the old panel and debris should be part of the job, and so should an updated panel directory — every breaker labeled with what it controls. A labeled panel is a safety feature for everyone who touches that box afterward, including the next electrician.
12. Can I talk to a recent customer? Ask for one or two references from jobs like yours, done recently. Plenty of homeowners skip making the call, but making the ask is still useful: watch the reaction. A pro with happy customers produces names the way they produce a license number — immediately, without a pause.
| Question | Reassuring Answer | Red Flag |
|---|---|---|
| License | Number given on the spot, verifiable online | "We don't need one for this kind of work" |
| Permit | "I pull it; the inspection is part of the job" | "Permits just slow things down and cost you" |
| Quote | Written and itemized, exclusions stated | A firm price over the phone for panel work |
| Payment | Modest deposit, balance after inspection | Full payment up front, cash only |
Pressure to sign today because a discount "expires." A price dramatically below two other written quotes — far below usually means something's missing from the scope, and it'll surface later as a change order. No physical address or company name you can look up. And urgency about problems you can't see, with no offer to show you. Real hazards do exist — the signs on this list of electrical warning signs are worth knowing — but a pro shows you the evidence instead of asking for your word on it.
Ask the twelve, listen less to the polish than to the paperwork: license and insurance without hesitation, a permit where one's required, a written itemized quote, staged payment, and a warranty on paper. An electrician who clears that bar will usually do the same quality of work once the panel cover comes off. The same sequence works, incidentally, for the other expensive trades — the list of questions to ask before hiring a plumber follows the identical pattern. The same goes for heating and cooling, the other big-ticket trade: keep this list of questions to ask before hiring an HVAC company handy when a furnace or AC replacement quote lands in front of you.
Go to your state licensing board's website and search by the license number or the company name. It's free, takes a couple of minutes, and shows whether the license is current and whether there are complaints or disciplinary actions on record. Do this before the work, not after a problem.
For genuinely small tasks, sometimes — but the line is drawn by local law, and in most places a handyman cannot legally replace a panel, add circuits, or do other permitted work. That's licensed-electrician territory. If the job needs a permit, it needs an electrician.
Often, yes. Many electricians charge a service or diagnostic fee to come out, troubleshoot, and quote — and frequently credit it toward the job if you hire them. A refusal to quote in writing afterward is a different matter.
It varies, but the pattern to look for is proportion: little or none for a small job billed on completion, a modest deposit on larger work, and the final payment tied to completion — after the inspection passes, when there is one. One hundred percent up front is never the right shape.
Plenty of work doesn't — like-for-like swaps of fixtures and devices often fall outside permit rules. The point of asking isn't to demand one; it's that a good electrician knows the local line cold and tells you plainly which side your job falls on.
