Workers' Comp Insurance for Plumbing Businesses in Tennessee

Plumbing contractors (NCCI 5183) typically face moderate workers' comp rates — much lower than roofing or framing, but higher than office-only operations. Lifting injuries and slip-and-fall claims drive most losses. Service plumbers, drain cleaning, and new-construction plumbing all use the same primary code but may have different sub-classifications in Tennessee. The Tennessee workers' compensation market is governed by NCCI, and the average rate statewide is approximately $0.97 per $100 of payroll.

Why plumbing workers' comp is tricky in Tennessee

Plumbers who do their own gas line work or HVAC ductwork may be misclassified — these activities have separate codes. Apprentices, clerical staff, and outside salespeople should be coded separately to keep your effective rate low.
