Statewide license

Issued by New Hampshire Mechanical Licensing Board, Office of Professional Licensure and Certification (OPLC)

New Hampshire issues a statewide Master Plumber license through the same OPLC Mechanical Licensing Board that licenses journeyman and trainee plumbers. The published two-year master plumber fee is $330 (OPLC fee table; Plc 1002.25). RSA 153:28, V lets the board enter mutual reciprocity agreements for plumbers, but the board publishes none. Since 3 May 2024, masters licensed in the jurisdictions OPLC lists under Plc 313.34 (Colorado, Connecticut, Delaware, Florida, Louisiana, Michigan, Rhode Island, Utah and Vermont) may be licensed by endorsement instead. Out-of-state masters who are not in a qualifying jurisdiction remain eligible for the New Hampshire plumbing examination upon proof of licensure (Mec 302.12).
