10 Questions to Ask Before Hiring an Electrician

Electrical work that fails inspection or violates code can burn your house down, void your insurance, and cost thousands to rip out and redo. A 10-minute conversation before signing a contract reveals whether you're dealing with a qualified electrician or someone who learned on YouTube. The following checklist covers National Electrical Code knowledge, insurance verification, and permit requirements -- the areas where unqualified contractors fall apart under questioning.

Questions to Ask

1Are you licensed as a journeyman or master electrician in this state, and can you provide your license number?

Why It Matters

Most states require a specific electrical license beyond a general contractor license. A journeyman has passed trade exams; a master electrician has additional years of supervised experience and can pull permits independently.

Red Flag

They say they work under someone else's license but that person won't be on site, or they cannot produce a license number you can verify online.

Pro Tip

A confident answer includes the license number and an invitation to verify it on your state's licensing board website. Many states let you look this up in under a minute.

2Will you pull the electrical permit, and is the final inspection included in your quote?

Why It Matters

Permitted work gets inspected by your city or county. Without a permit, you carry all liability if something goes wrong, and unpermitted electrical work can derail a future home sale.

Red Flag

They suggest skipping the permit to save money or time, or they say permits aren't required for your scope of work without explaining why.

Pro Tip

A good electrician will tell you exactly which permits are needed, factor the permit fee into the bid, and schedule the inspection as part of the project timeline.

3Have you performed a load calculation for my panel, and does it have capacity for this project?

Why It Matters

Every panel has a maximum amperage. Adding circuits for an EV charger, hot tub, or kitchen remodel without calculating existing load can overload the panel and create a fire hazard.

Red Flag

They plan to add circuits without checking your panel's existing load, or they dismiss load calculations as unnecessary.

Pro Tip

The electrician should reference a Manual J or NEC Article 220 calculation. If your panel is near capacity, they should quote a panel upgrade as part of the project.

4What is your approach to NEC code compliance, and which edition does our jurisdiction enforce?

Why It Matters

The National Electrical Code is updated every three years, but jurisdictions adopt different editions at different times. An electrician who knows your local amendments avoids failed inspections and rework.

Red Flag

They are unaware of which NEC edition your jurisdiction follows, or they dismiss code requirements as overly cautious.

Pro Tip

Look for familiarity with your local amendments. For example, many jurisdictions now require AFCI protection in bedrooms and GFCI protection in kitchens, bathrooms, and outdoor areas.

5Do you carry both general liability insurance and workers' compensation, and what are your coverage limits?

Why It Matters

If an uninsured electrician gets electrocuted in your attic or causes a fire, you could be personally liable. Workers' comp covers their injuries; general liability covers damage to your property.

Red Flag

They claim to be a sole proprietor who doesn't need workers' comp, or they cannot provide a certificate of insurance before starting work.

Pro Tip

Ask for a certificate of insurance naming you as the certificate holder. Call the insurance company directly to verify the policy is active, not expired.

6How do you handle existing aluminum wiring or knob-and-tube if you encounter it?

Why It Matters

Older homes may have aluminum wiring (1960s-70s) or knob-and-tube (pre-1950s), both of which require specific connection methods. Improper connections between aluminum and copper cause overheating.

Red Flag

They plan to connect copper to aluminum with standard wire nuts instead of approved COPALUM or AlumiConn connectors.

Pro Tip

A knowledgeable electrician will inspect your existing wiring during the estimate and flag any legacy wiring that needs special handling before starting work.

7What is your warranty on labor, and does it cover both materials and workmanship?

Why It Matters

Electrical components have manufacturer warranties, but the labor to install them is separate. If a connection fails six months later, you need to know who pays for the service call.

Red Flag

No written warranty at all, or a verbal promise with nothing in the contract.

Pro Tip

A one-year labor warranty is standard. Some electricians offer two years. The warranty should be written into the contract with clear terms about what it covers.

8Can you walk me through exactly what work you plan to do and which circuits will be affected?

Why It Matters

A detailed scope of work prevents misunderstandings about what's included. It also reveals whether the electrician has actually thought through the project or is improvising.

Red Flag

Vague descriptions like 'we'll figure it out once we open the wall' without any initial plan or contingency pricing.

Pro Tip

The best electricians provide a written scope that lists every circuit, device, and fixture involved, along with a labeled panel schedule update.

9How do you charge -- flat rate per job, hourly, or time and materials?

Why It Matters

Flat-rate pricing gives you cost certainty. Hourly or T&M can spiral if the job takes longer than expected. Understanding the pricing model upfront prevents billing disputes.

Red Flag

They refuse to give any estimate and insist on hourly billing with no cap, or the quote has no line-item breakdown.

Pro Tip

For defined projects like a panel upgrade, flat-rate is typical. For troubleshooting or discovery work, hourly with a not-to-exceed cap protects you.

10What is your timeline, and how many other jobs are you running simultaneously?

Why It Matters

Electricians juggling too many jobs often start yours, disappear for days, then return when it's convenient. A clear schedule with milestones keeps the project moving.

Red Flag

They cannot commit to specific start and completion dates, or they admit to running five or more concurrent projects.

Pro Tip

Ask for a written schedule with a start date, key milestones, and expected completion date. Include a clause in the contract addressing delays.

Bonus Tips for Hiring a Electrician

  • Get at least three written bids for any electrical project over $500. Compare scope of work, not just price -- the cheapest bid often omits permit costs or load calculations.
  • Verify the license online yourself. Every state has a searchable database. Do not rely on a photo of a license card.
  • Ask to see photos of recent completed work similar to yours. Panel upgrades, EV charger installs, and rewiring each require different expertise.
  • If the project involves opening walls, clarify who handles drywall patching and painting -- some electricians include it, many do not.
