Industrial Equipment Repair Insurance: GL, Completed Operations, Commercial Auto, and Workers Comp
Industrial equipment repair is classified as high-risk by insurance underwriters — and with good reason. A failed repair in a manufacturing facility can cause production downtime worth tens of thousands of dollars per hour, personal injury from equipment malfunction, and property damage to expensive machinery. The right insurance package protects your personal assets, satisfies customer vendor qualification requirements, and allows you to sign service contracts with confident liability language. This guide covers every coverage type your industrial repair business needs and what it will cost.

The Quick Answer
Your industrial repair insurance package should include: General liability ($1M per occurrence, $2M aggregate) — required by most industrial facility vendor qualification processes; Completed operations endorsement (covers damage caused by your work after you leave — critical for industrial repair); Commercial auto ($1M combined single limit for your service van or truck); Workers compensation (required in most states once you have employees, often required by customers even for sole proprietors); and Errors and omissions / professional liability ($1M, covers negligent advice or recommendation that results in equipment damage). Total annual cost for a solo operator: $4,000–$9,000 depending on your state, revenue, and niche.
General Liability: Your Foundation Coverage
Commercial general liability (CGL) insurance covers third-party bodily injury and property damage claims arising from your operations. For industrial repair, the key coverages within a GL policy are: premises and operations (coverage when you're at a customer facility doing work), products and completed operations (coverage for damage caused by your work after the job is complete — this is where most industrial repair claims originate), and personal and advertising injury (less relevant for industrial B2B, but included in standard GL). Industrial customers typically require $1M per occurrence and $2M aggregate — request these limits from your broker, not the minimums. Some large industrial accounts require $2M per occurrence and $4M aggregate — umbrella/excess liability ($1M–$5M on top of your GL) is the cost-effective way to meet these requirements ($800–$1,500/year for a $2M umbrella). When a customer requires you to name them as an additional insured on your GL policy, your insurance broker issues a Certificate of Insurance (COI) with an additional insured endorsement — standard practice, typically free.
Completed Operations: The Most Important Coverage for Repair Businesses
Completed operations coverage is part of most commercial GL policies, but verify it explicitly with your broker — some stripped-down contractor policies exclude it. Completed operations covers claims that arise after you've finished the job and left the premises. In industrial repair, the most common completed operations claim scenario: a motor you rewound fails 3 weeks later, causing the motor-driven equipment to shut down and damaging downstream product or processes. Without completed operations coverage, that claim is uninsured. With it, your GL carrier defends and pays (up to your limits). Completed operations coverage typically continues for 2–3 years after the work is completed — verify the tail period with your broker. Your service agreement's liability limitation clause (limiting your total liability to the repair cost) works alongside — not instead of — insurance to cap your exposure.
Commercial Auto: Covering Your Service Van
A personal auto policy does not cover your service van when it's being used for business purposes — the insurer can deny claims. Commercial auto insurance is required from day one of operating a business vehicle. For a single service van, a commercial auto policy ($1M combined single limit) costs $1,800–$3,600/year depending on your state, driving history, van value, and geographic coverage area. If you carry tools and equipment in your van (which you will), add an inland marine floater (tools and equipment coverage) — this covers theft, accidental damage, and loss of tools in the van. An inland marine policy for $10,000–$30,000 of tools costs $400–$800/year. Without it, tools stolen from your van are not covered by your commercial auto policy. Most commercial auto policies include hired and non-owned auto coverage (covers you when driving a rented vehicle or an employee's personal vehicle for business) — verify this is included.
Workers Compensation and High-Risk Industrial Classification
Workers compensation insurance is legally required in most states once you have any employees (requirements vary — some states exclude sole proprietors and partners, some require it for all). Industrial repair falls into high-risk workers comp classification codes: NCCI class code 3724 (machinery installation or repair) and 3726 (electrical machinery installation or repair) are the most common classifications for industrial repair technicians. High-risk classification codes carry higher rates — expect $8–$18 per $100 of payroll for industrial repair technicians, compared to $2–$4 for office workers. Even as a sole proprietor, some industrial customers require a workers comp certificate as a condition of vendor approval (they don't want to be liable if you're injured on their property and have no WC coverage). A sole proprietor WC policy (owner-only) costs $1,000–$3,000/year. As you hire technicians, your WC premium scales with payroll — factor it into your employee cost calculations.
Professional Liability and Contractual Risk Management
Errors and omissions (E&O) or professional liability insurance covers claims that your professional service or advice caused financial harm. For industrial repair, this applies to: recommending a repair approach that makes the problem worse, miscalculating the capacity of a repaired component resulting in equipment failure, or providing a maintenance assessment that overlooks a significant defect. E&O policies for industrial service companies run $800–$2,500/year for $1M limits. Pair your insurance with a strong service agreement: your liability limitation clause (capping your total liability to the repair amount) and your warranty disclaimer (limiting labor warranty to 30 days) are the contractual risk management tools that complement your insurance coverage. Your attorney and your insurance broker should review each other's work — the contract should align with the insurance coverage so there are no gaps.

FREQUENTLY ASKED QUESTIONS
How much does industrial equipment repair business insurance cost per year?
For a solo operator with one service van, a complete insurance package runs $4,000–$9,000/year: GL ($1,200–$2,500), commercial auto ($1,800–$3,600), inland marine/tools ($400–$800), E&O ($800–$1,800). Workers comp adds $1,000–$3,000 as a sole proprietor or $8–$18 per $100 of payroll for employees. A $2M umbrella adds $800–$1,500. These are 2026 estimates — rates vary significantly by state, niche (motor rewinding at height vs. general repair), and claims history.
Does my homeowner's insurance cover tools stolen from my van at home?
Most homeowner's policies exclude business property (tools, equipment used for business purposes) even when stored at home. Your commercial inland marine (tools and equipment) policy covers tools wherever they are — in your van, at a job site, or in your home workshop. Do not assume your homeowner's policy covers business tools. Verify in writing with your homeowner's insurer if you're uncertain.
What is completed operations coverage and why do I need it?
Completed operations coverage protects you from claims that arise after you've finished a job and left the customer's facility. In industrial repair, most claims come 1–90 days after the repair — a seal that fails, a winding that shorts out, a belt that breaks prematurely. Without completed operations coverage, these post-job claims are uninsured. Most commercial GL policies include completed operations, but verify with your broker — some stripped-down contractor policies exclude it to lower premiums. Never waive completed operations coverage in industrial repair.
