Nobody gets into electrical work because they love shopping for insurance. But one bad job without coverage puts a small shop out of business overnight. A journeyman drops a panel on a homeowner's hardwood floor. That's $15K. An apprentice falls off a ladder and breaks his back. That's $200K+ in medical bills. A fire starts from a connection you made six months ago. That's a lawsuit with six figures attached.
And beyond the risk, insurance is your ticket to work. GCs require a Certificate of Insurance before you step foot on any commercial job site. No COI, no work. Your bid doesn't matter. Your relationship with the GC doesn't matter. If your insurance isn't current, you're not getting on that site.
General liability
General liability is the foundation. This policy covers property damage, bodily injury to third parties, and completed operations claims, which are problems that show up after you've finished the job.
What GL covers:
- Damage to a client's property during work
- A visitor or client getting injured on your job site
- Claims from faulty work discovered after completion
- Legal defense costs
Typical limits: $1M per occurrence / $2M aggregate. This is the standard that almost every GC requires as a minimum. Some larger commercial GCs want $2M/$4M. But $1M/$2M gets you through most doors.
Cost range: $1,500 to $4,000 per year for a small shop with 1 to 5 employees. Your premium depends on revenue, payroll, claims history, and the type of work you do. Residential-only shops pay less. Industrial or high-voltage work costs more.
GL is non-negotiable. You do not operate without it.
Workers compensation
Workers comp is required by law in most states if you have any employees. Even one W-2 helper means you need a policy. It covers medical expenses, lost wages, and rehabilitation for employees injured on the job.
Key details:
- Rates are based on classification codes. Electricians fall under codes like NCCI 5190 for electrical wiring, which carries higher rates than office work.
- Cost is calculated per $100 of payroll. Typical range is $4 to $12 per $100 depending on your state and classification.
- A shop running $300K in annual payroll might pay $15,000 to $35,000 per year.
Even if you're solo, some GCs require you to carry workers comp or provide an exemption certificate. Without it, the GC's insurance might charge them for your coverage. They'll either pass that cost to you or find another sub.
States like California, New York, and Illinois are strict about enforcement. Running without it when required is a misdemeanor in some states, with fines starting at $10K.
Commercial auto
If your work trucks or vans are titled in your company's name, you need a commercial auto policy. Your personal auto insurance will deny any claim that happens during commercial use. And they will find out.
What commercial auto covers:
- Liability for accidents in company vehicles
- Physical damage to your vehicles
- Coverage for employees driving company vehicles
- Tools and equipment in transit, sometimes, depending on the policy
Cost range: $1,200 to $3,500 per vehicle per year. Depends on vehicle type, driver records, and coverage limits. A clean driving record across your team makes a big difference.
Even if the truck is in your personal name but you use it exclusively for work, talk to your agent. A personal policy with a business-use exclusion will leave you exposed.
Inland marine / tools and equipment
Here's one that catches a lot of electricians off guard. Your standard commercial property policy covers what's in your shop. Once your $3,000 Fluke meter, your benders, your drill kits, and your wire stock leave your building, they're not covered. You need inland marine insurance for that.
What it covers:
- Tools and equipment on job sites
- Materials in transit
- Rented or borrowed equipment
- Theft from your work vehicle, with limitations
Cost range: $300 to $1,500 per year depending on the total value you're insuring.
If you're carrying more than $10,000 in tools and materials to job sites, and most electrical contractors are, inland marine is worth every dollar. One stolen van full of tools without this coverage is a $20K+ loss out of pocket.
Professional liability
Professional liability, or errors and omissions insurance, covers claims arising from design mistakes, incorrect specifications, or professional advice that caused a problem.
Do you need it? If you're strictly doing install work from plans an engineer stamped, probably not. But if you do any design-build work, spec out panels and load calculations for clients, or provide consulting services, this protects you from claims that your design was faulty.
Cost range: $1,000 to $3,000 per year for small shops doing design-build.
Most electrical subs doing standard rough-in and trim work skip this one. But if design-build is part of your business model, don't go without it.
Umbrella / excess liability
An umbrella policy sits on top of your GL, auto, and workers comp policies. It kicks in when a claim exceeds the limits of your underlying coverage.
Why it matters: a $1M GL policy sounds like a lot. Until a serious injury claim lands on your desk. A fire in a commercial building traced back to your work generates claims north of $1M easily. An umbrella policy gives you an additional $1M to $5M in coverage.
Cost range: $500 to $2,500 per year for $1M in umbrella coverage. Cheap for that level of protection.
Consider an umbrella if you do commercial work, your projects regularly exceed $500K, or you work in multi-family residential. The exposure on these jobs justifies the extra layer.
What GCs require
Every GC has slightly different insurance requirements. Here's what you'll see on most subcontractor agreements:
- General liability: $1M per occurrence / $2M aggregate minimum
- Workers comp: Statutory limits, whatever your state requires
- Commercial auto: $1M combined single limit
- Additional insured endorsement: The GC and often the property owner must be listed as additional insured on your GL policy
- Waiver of subrogation: Your insurer agrees not to sue the GC to recover claim payments
- Certificate holder: The GC needs to be listed so they get notified if your policy lapses
Read the insurance requirements in a subcontract before you sign. Some GCs bury requirements for $5M in coverage or specific endorsements that your current policy doesn't include. Adding endorsements mid-policy usually costs $50 to $200 each. Better to know upfront than to scramble after you've committed to the job.
How to save on premiums
Insurance is expensive. There are legitimate ways to reduce your costs:
- Bundle policies into a Business Owner's Policy. Combining GL, property, and sometimes inland marine into one package saves 10 to 15% over separate policies.
- Maintain a clean safety record. Your experience modification rate directly impacts your workers comp premium. An EMR below 1.0 means lower rates. Invest in safety training. It pays for itself.
- Shop quotes every year. Loyalty doesn't get you discounts. Get three quotes annually. Your current carrier will often match a competitor's price to keep you.
- Raise your deductibles. If your cash flow handles a $2,500 or $5,000 deductible instead of $1,000, your premiums drop. Make sure you have the cash to cover the deductible if a claim hits.
- Pay annually instead of monthly. Most carriers charge 10 to 15% more for monthly payment plans.
Tracking your coverage
Certificates expire. Policies renew with different terms. You add a truck or hire an employee and forget to update coverage. A GC asks for a COI on a Friday afternoon and you're scrambling to reach your agent.
Build a system to track expiration dates, endorsements, and which GCs need updated certificates. Faraday helps you track documents including insurance certificates so nothing expires without you knowing. Whatever system you use, don't let this fall through the cracks. An expired policy is the same as no policy when a claim hits.
Insurance is not the exciting part of running an electrical business. But it's the difference between a bad day on the job and closing your doors.
