How to choose an electrician in New Hampshire
Verify the license and insurance
Electrical work in New Hampshire must be done or supervised by a licensed electrical contractor, and the license should be in the name of the company quoting you, not a friend of the crew. Look it up on the licensing board linked below, ask for proof of liability insurance, and confirm the contractor, not you, pulls the permit and schedules the inspection.
Start with a load calculation, not a panel size
For a panel upgrade, a new 240V circuit, or any electrification project, a good electrician runs the NEC Article 220 load calculation on your home before quoting. It decides whether you need a 200 A service upgrade (which involves the utility and the meter), a panel replacement at the same service size, a subpanel, or a load-management device that avoids the upgrade entirely. A quote that jumps straight to "200 amp upgrade" without the math is a guess.
Compare written quotes on the same scope
Get at least three quotes that name the panel brand and ampacity, the number of spaces, breaker types required by code (AFCI, GFCI), the wire gauge and run length for new circuits, whole-house surge protection, drywall repair, the permit and inspection fees, and the utility coordination. Ask what happens if the inspector flags existing issues, such as aluminum wiring or a missing ground, and whether those fixes are priced in.

Your utility sets the rate your new circuits draw from, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.
