Renting excavators, bulldozers, or track loaders? Insurance requirements can seem confusing, but they protect both you and the equipment owner. This guide explains exactly what coverage you need, how much it costs, and how to get your Certificate of Insurance (COI) approved quickly—including template emails you can send to your broker today.
What Is a COI and Why Do You Need One?
A Certificate of Insurance (COI) is a standardized one-page document that proves you carry the insurance coverage required by the rental company. It is not a policy itself—it is a snapshot of your existing policies that verifies coverage limits, effective dates, and named parties. Think of it as a receipt that says “yes, this person is insured.”
Rental companies require COIs to protect their assets. Heavy equipment is expensive—a mini excavator costs $50,000–$100,000 to replace, and a mid-size machine can exceed $200,000. Without insurance, a theft, accident, or total loss would leave the equipment owner bearing the full financial burden. The COI ensures that if something goes wrong, insurance covers it.
Required Coverage Types
Commercial General Liability (CGL)
CGL protects against third-party claims for bodily injury and property damage that occur during your use of the equipment. If someone is injured on your job site or you damage a neighbor's property while operating a rented excavator, CGL covers the claim. Most rental companies require a minimum of $2,000,000 per occurrence.
The rental company must be named as Additional Insured on your CGL policy. This means the policy extends coverage to the rental company for claims arising from your use of their equipment. Your broker adds this endorsement to your existing policy—it typically costs nothing extra if you already carry CGL.
Equipment Floater (Rented/Leased Equipment Coverage)
An equipment floater covers physical damage to the rented machine itself—theft, fire, vandalism, collision, overturning, and other covered perils. Coverage must equal the full replacement value of the equipment. For a $75,000 mini excavator, the floater must cover at least $75,000.
The rental company is listed as Loss Payee on the floater, meaning they receive the insurance payout directly if a covered loss occurs. Equipment floaters can be added to an existing contractor's policy or purchased as standalone short-term coverage. Standalone floaters typically cost $75–$200 per day depending on equipment value.
Environmental Liability (Sometimes Required)
Some owners require environmental liability coverage for fuel spills, hydraulic fluid leaks, or soil contamination. This is more common for larger machines operating near waterways or in environmentally sensitive areas. If required, your broker can add an environmental endorsement to your CGL or obtain a standalone policy.
How to Get Insurance
The process depends on whether you already have a business insurance policy or need to start from scratch.
If You Have an Existing CGL Policy
- Contact your broker and request a COI naming the rental company as Additional Insured
- Ask about adding a Rented/Leased Equipment endorsement to your existing policy
- Provide the rental company's legal name and address for the COI
- Confirm coverage dates span your entire rental period
- Turnaround: usually 24–48 hours
If You Need New Coverage
- Contact an insurance broker who specializes in contractor or equipment rental coverage
- Request a short-term CGL + equipment floater package for your rental period
- Provide details: equipment type, value, rental dates, and job site location
- Expect to pay $100–$300/day for a combined short-term package on a typical mini excavator

TEMPLATE
Subject: COI Request — Equipment Rental
Hi [Broker Name],

Common COI Mistakes to Avoid
- Wrong company name: The Additional Insured name must exactly match the legal name from your listing (equipment owner or platform where specified). Confirm the exact name with the equipment owner before requesting your COI.
- Expired dates: Ensure policy dates cover your entire rental period, including any potential extensions.
- Insufficient limits: If the rental company requires $2M CGL and your policy only shows $1M, the COI will be rejected. Confirm minimum limits before requesting.
- Missing Loss Payee: The equipment floater must list the rental company as Loss Payee, not just Additional Insured. These are different designations.
Frequently Asked Questions
What insurance do I need to rent equipment?
You typically need two types of coverage: Commercial General Liability (CGL) with a minimum of $2,000,000 per occurrence, and a Rented/Leased Equipment policy (equipment floater) covering the full replacement value of the machine. The rental company must be listed as Additional Insured on the CGL and Loss Payee on the equipment floater. Some owners also require Environmental Liability for fuel spill coverage.
How much does equipment rental insurance cost?
Short-term rental insurance costs $50–$200 per day depending on equipment value and coverage limits. A standalone equipment floater for a $75,000 mini excavator typically runs $75–$150/day. Annual CGL policies for contractors start at $500–$2,000/year. If you already have a business CGL policy, adding the rental company as Additional Insured is usually free—just ask your broker for a COI with the rental company named.
What is a COI for equipment rental?
A COI (Certificate of Insurance) is a one-page document from your insurance company that proves you have the required coverage. It lists policy numbers, coverage limits, effective dates, and names the rental company as Additional Insured and/or Loss Payee. Most rental companies require a COI before releasing equipment. Your broker can usually issue one within 24–48 hours of request.
