Electrical panel upgrades on Long Island are the most common residential electrical job we do — and the most consequential. Most Long Island homes built before 1980 still have original 100A service or, worse, Federal Pacific Stab-Lok panels that fail silently without tripping. A 200A panel upgrade is not optional when you add an EV charger, heat pump, or induction range — the math simply doesn't work at 100A.
Our panel upgrade process: we coordinate the PSEG disconnect, swap the meter pan, install the new panel (Eaton BR or Square D QO — no off-brand panels), land every circuit, label every breaker, and schedule the Nassau or Suffolk County electrical inspection. You get a green inspection tag before we leave. Most 100A-to-200A upgrades are completed in a single day. 400A service — for homes with whole-home generators, hot tubs, and EV chargers running simultaneously — typically runs two days.
Electrical panel upgrade cost on Long Island: A 100A service upgrade runs $1,800 – $3,200. A 200A panel upgrade is $2,800 – $5,200. A 400A service runs $6,500 – $12,000. These numbers include the permit, PSEG coordination, new meter pan, new panel, and all circuit reconnections. Nassau County towns (Hempstead, Levittown, Massapequa, Hicksville) and Suffolk County towns (Huntington, Babylon, Smithtown, Bay Shore) are all in our service area with no trip charge. Any electrician quoting under $2,800 – $5,200 for a 200A upgrade should be asked what they're omitting — most commonly it's the permit.
| Panel Upgrade Type | Cost Range (Long Island) | Timeline |
|---|---|---|
| 100A panel upgrade (new meter pan, panel, circuits) | $1,800 – $3,200 | 1 day |
| 200A panel upgrade (full service, permit, PSEG) | $2,800 – $5,200 | 1 day |
| 400A service upgrade (dual-panel, large home) | $6,500 – $12,000 | 2 days |
| 200A + subpanel add (garage, addition) | $2,800 – $5,200 + $800–$1,800 | 2 days |
| Federal Pacific Stab-Lok full replacement | $2,800 – $5,200 + $400–$900 | 1–2 days |
We don't chase HVAC, plumbing, or general handyman calls. We upgrade panels, install EV chargers, set generators, and rewire Long Island homes — and we've gotten pretty good at it.
Every Nassau and Suffolk town wants a filed permit and a passed inspection on electrical work. We handle it. If you'd rather talk to a licensed electrician than fill out a form, here's the number.
Every one of these is a Long Island house we worked on. "Before" is the panel the day we pulled up. "After" is the panel we handed to the inspector. No staging, no filters.
Your neighbor's guy doesn't. We file with Nassau or Suffolk, schedule the inspector, and hand you the green tag at the end. Your homeowner's insurance wants this. Your real-estate attorney will ask for it.
We don't do HVAC, plumbing, or handyman work. Just electrical. A journeyman on his 700th panel swap works differently from one on his 10th, and you'll see it in the torque marks on every lug.
We quote you a number. That's the number. No 'today only' discount, no manager call, no pressure to sign tonight. If you need a week to think, take a week.

No chatbot. No call center. Call Mon–Sat 7am to 7pm and you get Donna in dispatch or Frank in the truck. Nights and weekends, leave a message, we call back before the next morning.
Every person on our trucks lives on Long Island. Frank grew up in Hempstead. Kevin runs the Suffolk service truck. When we say we know Nassau and Suffolk, we mean we know which PSEG foreman handles which route.
“We called four electricians. Frank was the only one who actually looked inside the panel on the first visit. He showed us the burned neutral bar and explained why the dryer kept tripping. Pulled the permit, finished in a day, passed inspection first try. Hired them again a month later for the Tesla charger.”
“I got four quotes, read every Google review twice, and called two of their references. LI Electric Co. was not the cheapest. They were the ones who answered the phone, showed up when they said they would, and the price didn't move after we signed. Generator fired up two weeks later during a nor'easter. Worth every dollar.”
“Our 1952 cape still had some of the original knob-and-tube. Two electricians told us to 'live with it'. Frank walked us through the full rewire plan, pulled the permit, coordinated with the drywall guys, and finished in 8 days. House is finally safe and we can run a microwave and toaster at the same time.”
Our shop is on Fulton Avenue in Hempstead, smack in the middle of the island, so no address on Long Island is more than an hour from our front door.
Every other electrician website makes you fill out a form and wait. We built actual calculators so you can see a real ballpark and plan the job before you ever call us.
Every one of these is a real question we hear weekly on the phone, at walk-throughs, or at the Home Depot contractor desk. No corporate hedging, just the answer.
See all FAQsElectricians Long Island homeowners trust for serious work — panel upgrades, generator installs, EV chargers, whole-home rewires — share four credentials: (1) A Master Electrician license. New York State requires a Master Electrician to pull permits for service changes and generator hookups in Nassau and Suffolk. Ask for the license number. (2) A Nassau County and/or Suffolk County Home Improvement Contractor (HIC) license — each county requires its own, and a contractor licensed in one cannot legally pull permits in the other. (3) PSEG coordination experience. Panel upgrades and generator installs in Nassau and Suffolk require PSEG utility coordination for the disconnect and reconnect. Electricians Long Island who do this every week know the right contacts and can complete the process in a single day. (4) An active general liability certificate ($1M+) and workers' compensation on every crew member — not a blanket policy that excludes your job. Long Island Electric Co. holds both Nassau and Suffolk HIC licenses, employs a Nassau-licensed Master Electrician on every permit job, and is a Generac PowerPro Elite dealer for generator installations.
