Mechanical/Plumbing & Gasfitting

The NH State Fire Marshal’s office (NHFMO) administers licensing and certification for over 10,000 plumbing, gas, oil and water treatment tradespeople. Here you can learn about licensing requirements for the state. We also conduct municipal inspections.

Our highly qualified, in-house mechanical inspectors are also available to help municipalities with compliance inspections, answer code questions, and conduct inspections. Please note that while our building is currently closed to the public, we continue to serve you.

Plumbing Apprenticeship Information

To become a plumbing apprentice, the process starts with the Apprentice/Trainee Application Packet, located under our Mechanical Application and Forms section. Please note that there are separate packets for plumbing or gas, so make sure you’ve got the right one.

If you are interested in a career in plumbing and already have some knowledge, you may be eligible to bypass year 1 of the plumbing apprentice education requirement. We now have a first year bypass test available through the State of New Hampshire. Check our website for requirements, testing agencies and availability.
