Scope note: the filings tabulated above reflect NCCI class 9586 (Barber/Beauty Services) as an illustrative example of WC filing structure. Plumbing's actual WC class is NCCI 5183 (Plumbing NOC) — general plumbing contractors typically map to 5183; drain-cleaning specialists may also classify under 5188 (Plumbing — Drain Cleaning) and HVAC + plumbing combo operators may carry separate 5188/5190 classifications. Plumbing-specific advisory loss costs vary by state filing; the per-state ranges shown reflect cross-class WC mechanics rather than 5183 rates specifically. Confirm your specific class-code mapping at quote with your underwriter.
National context — Plumber insurance overview
Plumber insurance is dominated by one risk: water damage to customer property. A routine fixture replacement that leaks overnight can produce a $40K-$120K claim — flooring, drywall, cabinetry, electronics, mold remediation. General Liability is the workhorse coverage. Workers Comp under NCCI class 5183 (Plumbing NOC) typically runs $3-$7 per $100 of payroll. Service van Commercial Auto + Inland Marine for tools round out the standard stack. Sewer + drain work needs a Pollution Liability endorsement that most basic GL policies exclude.

Industry-typical market ranges (national)
Sourced from III, NCCI, ISO, NAIC, BLS, FMCSA, FDA, NRA — government and bureau publications, not from our quote form
Market ranges from published industry sources:
- General Liability: typically $1,378/year average for plumbing businesses (carrier benchmark data, 2024)
- BOP bundle (GL + Property + Business Income): typically $1,992/year average (carrier benchmark data, 2024)
- Workers Comp (NCCI 5183 Plumbing NOC): typically $3-$7 per $100 of payroll (national average $3.05; California $4.36-$8.58)
- Commercial Auto (service van): typically $1,500-$3,500/year per van (III + FMCSA)
- Inland Marine (tools + equipment): typically $200-$800/year depending on tool value (IRMI)
- Pollution Liability endorsement (any sewer or drain work): typically $500-$1,500/year — most basic GL policies exclude pollution claims
- Surety bond / contractor bond ($10K-$25K coverage typical, state-required): typically $100-$300/year
State variation is large — California, New York, and New Jersey are typically the most expensive (high tort + wage-hour exposure + earthquake-related plumbing risk). Texas, Florida, and most Midwest states are typically the least.

Industry context — what published research says about Plumber coverage
- Plumbing industry size: 480,000+ plumbers employed in the US (BLS). PHCC trade association represents thousands of plumbing + HVAC contractors. Plumbing-Heating-Cooling Contractors Association (PHCC).
- Water damage = the #1 claim driver: overflows from disconnected supply lines, leaks from worn fittings, pipe bursts during winter work, and sewer backups produce the bulk of plumbing GL claims. Typical claim severity $10K-$120K depending on flooring + cabinetry exposed. III.
- NCCI 5183 vs 5188: 5183 covers general plumbing (water, gas, steam — installation + repair). 5188 covers automatic sprinkler-system installation specifically — a different class with different rate. Mixed crews need payroll split. NCCI Atlas.
- Pollution Liability + sewer work: standard GL policies exclude pollution claims under the "absolute pollution exclusion" — including most sewer + drain backup claims that involve raw sewage. A Pollution Liability endorsement closes the gap. Plumbers doing any drain or sewer work without it have uncovered exposure. IRMI.
- Contractor licensing + bonding: most states require plumbing contractor licensure + a surety bond ($10K-$25K typical). Bonds protect customers from incomplete work + contract default — they are NOT insurance for the plumber. Verify state contractor licensing board requirements. NAIC insurance topics.
