Cost in New Hampshire
The line items below are national 2026 planning ranges for this work. Local variation in New Hampshire comes from labour rates, permit fees and access — not from the job description.

What the work involves
- Panel-mounted SPD sized to the service and installed on a dedicated breaker
- Correct grounding and bonding verification, since SPD performance depends on it
- Point-of-use protection recommendations for sensitive electronics
- Testing and documentation of the installation for insurance purposes
- Explanation of what protection does and does not cover
What drives the price in New Hampshire
Surges come from inside the house far more often than from lightning: motors and compressors switching on and off create repeated small events that degrade control boards over years.
An SPD is only as good as the grounding system it connects to, which is why a grounding inspection is part of a proper installation.

Whole-House Surge Protection in New Hampshire — FAQ
Does whole-house surge protection need a permit in New Hampshire?
Permit requirements depend on the job and on your city or county, not just the state. Work involving a panel, a service change, new circuits or wet locations almost always needs one, and the inspection is carried out locally. Ask the contractor to confirm and to file it.
Do you charge for estimates?
Many contractors give a free estimate on planned work such as a panel replacement, charger install or rewire, while diagnostic visits for an unknown fault usually carry a trip fee that is often credited toward the repair. The exact policy varies by contractor, and it should be confirmed on the phone before anyone travels.
How much does an electrician cost per hour?
Licensed residential electricians generally charge in the $50 to $150 per hour range in 2026, plus a service call fee of roughly $75 to $200. Most companies now price common jobs flat-rate rather than hourly, which means the number you are quoted is the number you pay if the scope does not change.
What should I do while waiting for an electrician?
For an urgent fault, switch the affected circuit off at the panel and leave it off. If the panel itself is hot, smoking, sparking or wet, do not touch it and keep everyone away from it. Never pull a meter or open a panel, and never pour water on anything electrical.
Who does whole-house surge protection in New Hampshire?
Whole-house surge protection in New Hampshire is performed by licensed electrical contractors working within their own local service areas. The network covers 147 ZIP codes here, and requests are routed by address rather than by city name.
Do you handle both homes and small businesses?
Most local electrical contractors take residential work and light commercial work such as retail, restaurant and office premises, including three-phase distribution, lighting retrofits and dedicated equipment circuits. Larger commercial projects are quoted from a site survey.
What does whole-house surge protection cost in New Hampshire?
The national 2026 range for this work is $300 to $900. Expect New Hampshire pricing to sit somewhere in that band, adjusted for local labour rates, permit fees and how accessible the wiring is. Ask for a flat price per task rather than an hourly estimate.
Which cities in New Hampshire request this most?
The highest volume comes from Manchester, Nashua, Concord, Portsmouth, Rochester and the surrounding suburbs, which is where the densest housing stock and the oldest wiring systems tend to be.
