Insurance is Not Optional for Field Service Contractors
A single uninsured incident — a customer falling while you're on their property, a fire traced to your electrical work, a vehicle accident on the way to a job — can result in a lawsuit that exceeds everything you own. For field service businesses, insurance is the foundation of financial protection, professional credibility, and often contractual necessity.
This guide covers the four types of insurance every contractor should understand, what they cost, what they cover, and what gaps to watch for.
The Four Insurance Categories
1. General Liability (GL)
Covers third-party bodily injury and property damage caused by your business operations. If you accidentally damage a customer's property or a bystander is injured at a job site, GL pays. Most policies have a $1M per-occurrence limit with a $2M aggregate.
Typical annual cost: $500–$1,500 for a sole proprietor; $1,500–$4,000 for small crews
Required by: Most commercial clients, large residential properties, HOAs
2. Workers' Compensation
Covers medical expenses and lost wages if you or your employees are injured on the job. Most states require workers' comp the moment you hire your first W-2 employee — some even require it for owners of certain business types. As a sole proprietor you can often opt out, but getting hurt on a job without it means your personal health insurance pays (or doesn't).
Typical annual cost: 1–5% of payroll, depending on trade risk classification
Required by: Most states once you have W-2 employees; many commercial contracts
3. Commercial Auto
Your personal auto policy does not cover a vehicle used for business. If you're in an accident driving to or from a job site, a personal auto policy can deny the claim. Commercial auto covers vehicles used in the course of business operations.
Typical annual cost: $1,500–$3,000 per vehicle
Required by: Any contractor carrying business tools or equipment in their vehicle
4. Tools and Equipment / Inland Marine
Covers your tools and equipment against theft, damage, or loss — whether at a job site, in transit, or in your vehicle. Standard GL and auto policies do not cover tools. Tool theft from job sites and vehicles is one of the most common contractor losses.
Typical annual cost: $300–$800 for $10,000–$25,000 in coverage
Required by: No one — but often the right decision
| Insurance Type | What It Covers | Annual Cost Range | Priority |
|---|---|---|---|
| General Liability | Third-party injury and property damage | $500–$4,000 | Essential |
| Workers' Comp | Employee on-the-job injuries | 1–5% of payroll | Required w/ employees |
| Commercial Auto | Vehicle accidents on business use | $1,500–$3,000/vehicle | Essential |
| Tools & Equipment | Tool theft, damage, loss in transit | $300–$800 | Highly recommended |
What's NOT Covered (Common Misconceptions)
- GL does not cover your employees' injuries (that's workers' comp)
- GL does not cover faulty work — it covers damage caused by your work, not the work itself
- Commercial auto does not automatically include cargo/equipment in the vehicle
- Workers' comp does not cover 1099 subcontractors (they need their own policy)
Talk to an independent insurance broker who specializes in contractors — they can compare rates across multiple carriers and ensure you're not paying for overlapping coverage.
Key Takeaways
- Every contractor needs GL and commercial auto before starting any paid work
- Workers' comp is legally required once you hire W-2 employees in most states
- Tools and equipment coverage is inexpensive and frequently worthwhile
- GL does not cover faulty workmanship — that requires a separate contractors' errors and omissions or performance bond
- Use an independent broker who specializes in contractors to compare rates
