Bringing your license from another state
Nothing to bring — New Hampshire's mechanical licensing is FUEL-scoped: gas fitters, fuel gas fitting trainees, oil heating technicians, domestic appliance tiers. We read the complete license-type catalog and none of it is pipefitting — an NH 'gas fitter' card is a FUEL-GAS credential. Steam, hydronic and process piping carry no New Hampshire card.
Can you work while it is pending?
Nothing pending on fitter scope. Fuel-side placements have the trainee license as the supervised entry lane.
The exam and the hours
No fitter exam exists. Fuel-gas piping runs on the Saf-Mec gas fitter ladder; plumbing scope on the journeyman plumber card. One boundary we still pin before advising on comfort-steam jobs: whether NH's plumbing definition reaches hydronic heating piping — ask OPLC on a hydronic placement.
How apprenticing works here
No fitter tier. The FUEL GAS FITTING TRAINEE is the fuel-side supervised entry; plumbing apprenticeship rides that board.
The local picture
Not checked for worker cards — no municipal fitter card is known.
If you want to contract for yourself
New Hampshire runs no general contractor licensing; the mechanical and plumbing boards' credentials anchor their own trades. Expect NO card to verify on steam and process piping crews.
Checked against the state board or statute. Rules change — confirm with the board before you travel or accept work. This is information, not legal advice.
