Insurance requirements for electrician subcontractors
What policies to require, what limits to set, and what to look for on the COI before an electrician starts work.
Electrical work is one of the most closely inspected trades on any project. A wiring error can cause a fire years after the job is complete, which means completed operations coverage is not optional. It needs to survive past the project end date.
Most GC contracts require a minimum of $1 million per occurrence and $2 million aggregate on general liability, plus workers' compensation and commercial auto. On larger commercial or industrial projects, umbrella limits of $2 million or more are common. Here is what to collect and what to verify.
Policies to require
Policy
Typical limit
Why it matters
General Liability
$1M per occurrence / $2M aggregate
Covers third-party bodily injury and property damage; completed operations covers post-project claims from faulty wiring.
Workers' Compensation
Statutory limits
Required in nearly every state for any sub with employees. Electricians have a moderate-to-high injury rate; confirm the policy is not limited to a narrow class.
Commercial Auto
$1M combined single limit
Covers vehicles used to transport tools and crew to your site.
Umbrella / Excess Liability
$1M to $2M+ (project-dependent)
Sits above GL and auto; commonly required on commercial and government projects.
Professional Liability (E&O)
$1M per claim
Required if the electrician provides any design, engineering, or design-build services. Not standard for pure install work.
Typical limits reflect common GC contract requirements as of 2026. Actual requirements vary by contract, project size, owner, and jurisdiction.
What to verify on the COI
When you receive the certificate of insurance from a electrician, check each of the following before approving the document.
Named insured matches the legal entity name in your subcontract
Certificate holder lists your company name and address
Your company is endorsed as additional insured on the GL policy
GL policy dates cover the full project duration, including a completed-operations tail if the project spans renewal
GL limits meet your contract minimums (check per-occurrence AND aggregate)
Workers' comp policy number is present; if absent, verify whether the sub qualifies as a sole proprietor exclusion
Auto policy covers all owned, hired, and non-owned vehicles
Common gaps and watch-outs
Residential vs commercial classification
Some electrician GL policies are classified for residential work only. They may not cover commercial or mixed-use projects. Ask for the full declarations page or confirm the class code covers your project type.
Completed operations expiration
Standard COIs show the policy period, not whether the completed-operations extension is in force. If the project runs past the policy renewal, you need confirmation the new policy also includes completed operations, not just the certificate dates.
Workers' comp class codes
Workers' comp premiums are based on class codes. An electrician doing switchgear installation carries a different rate than one doing residential rough-in. Verify the class code actually covers the work being performed on your project.
Design-build without professional liability
If you are asking an electrician to design a system and install it, their GL does not cover the design error. That requires a professional liability (E&O) policy. Confirm before the scope is set.

What insurance does an electrician subcontractor need?
At minimum: general liability ($1M/$2M), workers' compensation (statutory limits), and commercial auto. Larger commercial projects typically add an umbrella policy. Design-build scopes also require professional liability.
Do I need to be listed as additional insured on an electrician's policy?
Yes. The additional insured endorsement extends the sub's GL coverage to protect you if someone makes a claim that involves your site or project. Without it, the sub's insurer can decline to defend or indemnify you.
What is completed operations coverage and why does it matter for electricians?
Completed operations is the part of general liability that covers claims arising after the work is finished. Electrical defects often cause fires or failures months or years later. Confirm it is included and that it will not lapse at renewal while your project is still under warranty.
Can a sole proprietor electrician waive workers' comp?
In most states a sole proprietor with no employees can legally waive workers' comp for themselves. If they are injured on your site, however, they may still pursue a claim through other channels. Know your state's rules and consider requiring a written waiver.
