Electrical contractor: New Hampshire Requirements

Electrical contracting covers everything from service calls and panel upgrades to new construction and EV chargers. It is one of the most tightly licensed trades, and most owners start as licensed electricians. Permits, inspections and code compliance shape nearly every job.

New Hampshire requirements for this business

  • New Hampshire's Electricians' Board licenses master, journeyman and high/medium voltage electricians, and registers apprentice electricians and high/medium voltage trainees. [source]
  • Licensing covers electrical installations for heat, light and power regardless of voltage; the board says signaling circuits such as fire alarms currently require no license. [source]
  • Journeyman reciprocity under the NERA agreement requires holding a New Hampshire journeyman license for at least one year, 8,000 hours of practical experience and at least 600 hours of electrical schooling. [source]

Equipment and supplies

  • Multimeter, clamp meter and non-contact voltage tester

  • Conduit benders, fish tapes and wire pullers
  • Drills, hole saws and reciprocating saw
  • Fiberglass ladders
  • PPE rated for electrical work
  • Service van with wire and parts storage

Licenses and registration

  • If you form an LLC or corporation, register it with your state; if you use a business name other than your own, file a trade name (DBA) where your state requires it (in some states that's the county).
  • Most states license electricians individually (often apprentice, journeyman and master levels), and many also require a separate electrical contractor license for the business; in some states licensing is handled by cities or counties — check your state licensing board and your city.
  • Most electrical work needs a permit and inspection from the local building department; check which version of the electrical code your area enforces.
  • EPA's Renovation, Repair and Painting (RRP) rule names plumbers and electricians among the special trade contractors it covers: firms paid for work that disturbs paint in homes and child-occupied facilities built before 1978 must be certified, even sole proprietorships, unless an exemption such as minor repair (6 square feet or less per room inside, 20 square feet or less outside) applies. [source]
  • Some states run their own lead-based paint (RRP) program instead of EPA; if yours does, certify with the state. [source]
  • If you have employees, OSHA safety rules apply, including rules for electrical safety and ladders.
  • Commercial clients and general contractors often ask for a certificate of insurance, a W-9 and proof of license.
  • Get a free Employer Identification Number (EIN) from the IRS if you will hire employees or form an LLC or corporation. Beware of sites that charge for this. [source]
  • To find your state's business registration office, use the SBA's state-by-state registration lookup. [source]

Insurance to consider

  • General liability (fire and property damage claims)
  • Commercial auto for work vans
  • Tools and equipment (inland marine) coverage
  • Workers' compensation once you hire
  • Contractor license bond if your state or city requires one

Get quotes from several carriers or an independent agent; coverage needs depend on your contracts, state and staff.

Financing options

  • SBA 7(a) loans — the SBA's main guaranteed loan program, made through participating lenders. [source]
  • SBA Microloans — smaller loans delivered through nonprofit intermediary lenders. [source]
  • SBA Lender Match — a free tool that connects you with interested SBA lenders. [source]
  • Free counseling from your local SBDC or SCORE chapter can help you build the business plan lenders ask for. [source]
