Panel Upgrade Cost in New Hampshire

Here is the honest answer first. National cost guides put a typical 100-to-200-amp electrical panel upgrade in the range of about 1,300 to 4,000 dollars, and a full service upgrade that adds a new meter base, service-entrance cable, and utility coordination runs toward the higher end of that. Your real number depends on three things: the amperage you need, the condition of your service entrance, and what kind of panel you have today. Our licensed electricians give you an exact figure after looking at your panel, and the estimate is free.

What actually drives the price of a panel upgrade?

The biggest movers are the size of the new service, how much of the service entrance has to be rebuilt, and the panel you are replacing. Swapping a modern 100-amp panel for a 200-amp panel in the same spot is a smaller job than moving from an old fuse box or a failure-prone brand, which often means a new meter base, fresh service-entrance cable, a grounding and bonding upgrade to current code, and a coordinated disconnect and reconnect with the utility.

There are also real line items that have nothing to do with the panel on the wall. A permit and inspection is one. Bringing the work up to the current National Electrical Code is another, since a service upgrade now pulls in requirements like a surge protective device on the service and arc-fault and ground-fault protection on the circuits it touches. Accessibility can matter too: a panel buried behind a finished wall, in a tight closet, or in a damp basement corner takes longer to do right than one on an open cellar wall. And if an older home in Southern NH or the Merrimack Valley has knob-and-tube or aging aluminum branch wiring that has to be dealt with at the same time, that adds to the day. We tell you which of these apply to your home before we start, so the quote you get is the price you pay.

What is the difference between a panel swap and a full service upgrade?

It is worth knowing which job you are actually pricing, because the words get used loosely. A panel swap, sometimes called a panel replacement, changes the breaker panel itself while keeping the existing service size, meter, and entrance cable. A service upgrade raises the capacity coming into the home, for example from 100 amps to 200 amps, which usually means a new meter base, a heavier service-entrance cable, updated grounding and bonding, and coordination with Eversource or Unitil to disconnect and reconnect the power. A service upgrade almost always includes a new panel, but a panel swap is not always a service upgrade. We tell you plainly which one your home needs, and we never charge you for a full service upgrade when a straightforward panel replacement is the honest fix.

What does a panel upgrade cost in New Hampshire and Massachusetts?

The ranges above are national figures meant to set expectations, not a quote for your home. National cost guides such as This Old House report that a 100-amp service commonly lands around 1,200 to 1,800 dollars, a 150-amp job in the low-to-mid thousands, and a 200-amp upgrade often between about 1,300 and 4,000 dollars once the meter, cable, and labor are counted. Whether you are in Atkinson and Salem on the New Hampshire side or Methuen and Haverhill across the Massachusetts line, the same three drivers set the price, and the free on-site estimate is how you turn a range into a real number.

One thing that does not change the honest way the quote is written is the state line. Lembo Electric's owner, Paul Lembo Jr., holds New Hampshire Master Electrician license number 13087 and Massachusetts Master Electrician license number 9058-EL-A1, and the company is licensed and insured in both states. We will not pad a number because a job sits in one state or the other. Honesty and Quality above all else is how the estimate gets written on either side of the border, and the number we write is the number you pay.

Do I need a permit, and is it different in NH versus MA?

Yes, a service or panel upgrade needs an electrical permit and an inspection in both states, and a licensed electrician is who pulls it. New Hampshire licenses electricians through the Office of Professional Licensure and Certification and follows the National Electrical Code as adopted by the state. Massachusetts adopts the NEC as the Massachusetts Electrical Code, 527 CMR 12, with state amendments, and the permit is filed with the local inspector of wires in your city or town.

The practical difference for you as a homeowner is small: the correct permit gets pulled, the work is done to that state's adopted code, and the inspector signs off. What matters is that a licensed pro does it. An unpermitted panel becomes your problem when you sell the house, when your insurer asks, or when the next electrician has to correct work that was never inspected. We handle the permit and meet the inspector as part of the job, so the paper trail is clean and the work is on record.

Why are so many Southern NH and Merrimack Valley homes upgrading right now?

A panel that was plenty for a 1980s house is often full today. Heat pumps, EV chargers, hot tubs, and a kitchen full of modern appliances all pull real load. When homeowners in Atkinson, Salem, Derry, and over in Methuen call about a new EV charger or a standby generator, the first question is almost always whether the existing service can carry it. Sometimes it can. When it cannot, right-sizing the panel now is cheaper than doing it twice, and it clears the way for the next few projects instead of blocking them.

The trend toward electrification is a big part of it. As more of the home runs on electricity instead of oil, propane, or gasoline, the service that feeds it has to grow with it. A house adding a heat pump for heating and cooling, an induction range, a heat-pump water heater, and an EV charger is asking far more of its panel than the same house did a decade ago. Getting ahead of that with one well-planned upgrade beats a string of emergency fixes.

Is a 200-amp service worth it over 100-amp?

For most homes adding load, yes. A 200-amp service gives you headroom for the panel to breathe and room for the circuits your next few projects will need, from an EV charger to a heat pump to a finished basement. That said, we will not upsell you into amperage you do not need. If your 100-amp service is healthy and your plans are modest, we say so. The right size is the one your home genuinely calls for, not the biggest number on the invoice, and a load calculation on your actual home is how that gets decided rather than a guess.

Can a rebate or utility program lower the cost?

Sometimes, indirectly. The panel upgrade itself is usually not a rebated item, but the equipment that often drives the upgrade can be. In New Hampshire, NHSaves, the program run by Eversource, Unitil, and the state's other utilities, offers incentives on qualifying heat pumps and other efficient equipment. Federal tax credits for efficiency-linked panel work (the 25C credit) ended for work placed in service after December 31, 2025; our NH electrical rebates and incentives guide, linked below, covers what is current. Across the line, Mass Save runs the comparable Massachusetts incentives. We will point you to the current programs that fit your project so you are not leaving money on the table, though we leave the paperwork math to you and the utility, since program terms change and we will not promise a number we do not control.

How do I know it is time for a panel upgrade?

Common tells are a fuse box still in service, breakers that trip often, a panel that feels warm to the touch, lights that dim when a big appliance kicks on, and no open slots for a new circuit. A known problem-brand panel is another. If any of those sound like your home, a look at the panel is the right first step, and it costs you nothing to have us come see it. There is a companion article on the five clearest signs if you want to walk through them one by one before you call.

Will you give me a real price, or just a range?

A real price. The ranges here are national figures to set expectations. We come out, look at your actual service, check the meter base and the entrance cable, count your load, and give you a written estimate for your home, and the work comes in at that number. Call for your free estimate in Atkinson, across Rockingham County, and throughout the Merrimack Valley on both the New Hampshire and Massachusetts sides.
