Business Owners Policy for Plumbers

Q: Is a BOP the same as general liability for plumbers?

No. A BOP includes general liability but also adds commercial property coverage — and typically business income/extra expense — in one bundled package. Standalone general liability is just the CGL portion.

Q: Can I add my apprentice or helper to a BOP?

No. Employee injuries are covered by workers' compensation, not a BOP. If you have employees — even part-time or casual helpers — most states require you to carry workers' comp.

A plumbers business owners policy (BOP) bundles general liability and commercial property coverage into one affordable package designed for small-to-mid-size plumbing contractors. Most plumbing shops with fewer than 100 employees and under $5 million in annual revenue qualify. Premiums typically range from $1,200 to $3,800 per year, depending on payroll, revenue, and operations.

Who this is for: Licensed plumbing contractors — sole proprietors, partnerships, and small LLCs — who want foundational coverage in a single policy rather than buying general liability and property separately.

TL;DR — Key Takeaways

A BOP combines general liability (third-party bodily injury and property damage) and commercial property (your tools, office, and equipment) in one policy, usually at a lower combined premium than buying each separately.
Standard BOP limits for plumbers start at $1M per occurrence / $2M aggregate for liability, with property coverage sized to your business personal property value.
A BOP does not include workers' compensation, commercial auto, or professional liability — those require separate policies.
Plumbing-specific endorsements — like contractor's errors & omissions and tools and equipment floaters — can be added to fill common coverage gaps.
Most carriers can bind coverage and issue a certificate of insurance (COI) same day or next business day.

What Does a BOP Cover for a Plumbing Business?

A standard BOP issued on an occurrence form combines two core insuring agreements:

1. Commercial General Liability (CGL) Covers third-party claims for bodily injury or property damage caused by your operations, products, or completed work. For plumbers, this typically includes:

A customer slipping on standing water while you're on the job
A pipe you installed leaking and damaging a finished basement
A fire caused by a torch during soldering work

Completed Operations coverage — included in most BOPs — extends protection to work you've already finished if damage surfaces weeks or months later.

2. Commercial Property Covers your owned or leased business property against covered perils (fire, theft, vandalism, certain water damage). For a plumbing company this means:

Office contents, computers, and records
Tools and equipment stored at a fixed location
A small shop, warehouse, or yard

Coverage Component	What It Covers	What It Does NOT Cover
GL — Premises & Operations	Injury/damage during active work	Your own employees' injuries
GL — Products & Completed Ops	Damage from finished work	Intentional acts, professional errors alone
Business Personal Property	Tools/equipment at your location	Tools in transit or at job sites (needs floater)
Business Income / Extra Expense	Lost income after a covered property loss	Income loss from a liability claim
Medical Payments	Minor injuries without litigation	Injuries to employees

Coverage gap to know: A standard BOP property form covers tools at your shop — but tools in your van or on a job site are typically excluded. A Contractor's Equipment Floater (sometimes called a Inland Marine policy) fills this gap.

How Much Does a BOP Cost for Plumbers?

BOP premiums for plumbing contractors are underwritten primarily on annual revenue, payroll, years in business, claims history, and state. The table below shows representative annual premium ranges for illustrative purposes — your actual quote may differ.

Business Profile	Annual Revenue	Estimated Annual BOP Premium
Solo plumber / sole proprietor	Under $300K	$1,200 – $1,800
Small shop (2–5 employees)	$300K – $750K	$1,800 – $2,800
Mid-size contractor (6–15 employees)	$750K – $2M	$2,800 – $4,500
Larger plumbing company	$2M – $5M	$4,500 – $8,000+

Factors that raise premiums: - Residential new construction work (higher completed-operations exposure) - Gas-line or medical/industrial plumbing - Prior liability or property claims in the last three to five years - Working in high-cost states (CA, NY, FL)

Factors that lower premiums: - Five-plus years in business with clean loss history - Commercial maintenance or service work only (lower severity) - Bundling BOP with workers' comp or commercial auto under one carrier

What a BOP Does NOT Cover — Plumber-Specific Gaps

Coverage You Still Need	Why Plumbers Need It	Typical Separate Policy
Workers' Compensation	Required in most states once you have employees [verify state]; covers job-site injuries	Standalone WC policy
Commercial Auto	Vehicles used for work are excluded from BOP property and liability	Commercial Auto
Professional / E&O Liability	Design errors, spec mistakes on plumbing systems	Contractor's E&O endorsement or standalone
Contractor's Equipment Floater	Tools and equipment off-premises or in transit	Inland Marine / Equipment Floater
Umbrella / Excess Liability	General contractors often require $2M–$5M limits; BOP base may be insufficient	Commercial Umbrella
Pollution Liability	Sewage backup, chemical releases — typically excluded from CGL	Contractor's Pollution Liability

How to Get a BOP as a Plumbing Contractor — 5 Steps

Gather your business information. Pull together your annual gross revenue, payroll (split by employee class), a list of the types of plumbing work you do (residential, commercial, new construction, service/repair), your state contractor's license number, and any prior claims for the past three to five years.
Identify your property values. Estimate the replacement cost of your business personal property — tools, office equipment, inventory of materials kept on hand. This sets your property limit.
Confirm what limits your contracts require. General contractors and property managers often require $1M per occurrence/$2M aggregate minimum, plus additional insured status. Review your contracts before quoting.
Request quotes from multiple carriers. An independent agency (like Morrow) will shop your account across multiple admitted and non-admitted carriers. BOP eligibility rules vary — some carriers won't write plumbers doing new construction; others specialize in contractors.
Review the policy form and endorsements before binding. Confirm the occurrence form, check exclusions for subsidence and faulty workmanship, and add any needed endorsements (tools floater, E&O, additional insured blanket form) before you sign.

Real-World Example: Completed-Operations Claim for a Texas Plumber

Scenario (illustrative — not a guarantee of coverage or outcome):

A licensed plumbing contractor in Austin, Texas replaces a water heater and reconnects supply lines for a residential customer. Six weeks after the job is complete, a compression fitting fails overnight, flooding the home's first floor. The homeowner submits a claim for $38,000 in flooring, drywall, and contents damage, plus $9,500 in additional living expenses while repairs are underway.

The plumber's BOP included Products and Completed Operations coverage at $1M per occurrence.
The carrier accepted the claim under the completed-operations insuring agreement.
After a $1,000 occurrence deductible, the carrier paid $46,500 in covered damages — well within the per-occurrence limit.
The plumber's experience modifer (EMR) was not impacted because the claim was on a general liability policy, not workers' comp.

What would NOT have been covered: If the plumber had also damaged a nearby gas line during the job, a resulting pollution or combustion claim could have triggered the pollution exclusion in the standard CGL form — a strong reason to discuss a Contractor's Pollution Liability rider with your broker.

Frequently Asked Questions

Q: Is a BOP the same as general liability for plumbers? No. A BOP includes general liability but also adds commercial property coverage — and typically business income/extra expense — in one bundled package. Standalone general liability is just the CGL portion.

Q: Do I need a BOP if I'm a solo plumber with no employees? A BOP still makes sense for most solo plumbers. You have tools and equipment to protect, and any job site accident can generate a six-figure liability claim. Many general contractors and property managers will not hire you without documented general liability coverage.

Q: Will a BOP cover my plumbing van? No. Commercial vehicles are excluded from BOP coverage for both property (physical damage) and liability purposes. You need a separate commercial auto policy for any vehicle used in your business — including personal vehicles driven for work purposes.

Q: How quickly can I get a certificate of insurance (COI)? Most BOP carriers can issue a COI within 24 hours of binding coverage, and many independent agencies can turn around a COI the same day. If a general contractor needs proof of insurance before you start a job Monday morning, binding Friday is typically sufficient.

Q: What liability limits does a general contractor usually require from a plumbing subcontractor? The most common minimum requirement in commercial construction subcontracts is $1M per occurrence / $2M general aggregate, often with the GC named as an additional insured. Some large commercial projects require a $5M umbrella in addition to the BOP limits. Always review subcontract insurance requirements before bidding.

Q: Can I add my apprentice or helper to a BOP? No. Employee injuries are covered by workers' compensation, not a BOP. If you have employees — even part-time or casual helpers — most states require you to carry workers' comp. Working without it where required can expose you to fines and personal liability for injury claims [verify state].

Q: Does a plumbers BOP cover water damage I accidentally cause? Yes — accidental water damage to a third party's property caused by your active operations or completed work is a standard CGL covered cause. However, the BOP will not pay to repair or replace your own faulty work itself (the "your work" exclusion in the CGL form). Coverage pays for the resulting damage, not the cost to redo the work.

Q: How does my BOP interact with a homeowner's insurance claim? If a homeowner's carrier pays a water damage claim and believes your work caused the loss, they can subrogate (step into the homeowner's shoes) and sue you for reimbursement. Your BOP's completed-operations coverage responds to such subrogation claims. A waiver of subrogation granted by the homeowner in your favor (typically arranged through your customer contract) can prevent this in some contractual situations — ask your broker if it's required in your contracts.
