Insurance for Electricians
Electrical claims tend to be few and large: a fire traced to a panel you upgraded, or a shock on a job you finished months ago. We shape electrician insurance around the wiring you sign off on and the contracts you work under.
Fire, shock and the work you leave behind
The CSLB defines a C-10 electrical contractor as one who installs or connects wires, fixtures, appliances, raceways, conduits and solar photovoltaic cells that generate, transmit, transform or use electrical energy. That reaches almost anything with a circuit, and the claims that follow electrical work tend to be serious ones: a structure fire, a tenant’s damaged equipment, or someone hurt by a live conductor.
Most of those claims arrive after you have packed up. A loose termination or an overloaded circuit can run for months before it fails, and a fire blamed on that wiring is a completed operations claim under your general liability. The standard form pays such claims from a products-completed operations aggregate kept apart from the general aggregate, so that figure deserves the same attention as the per-occurrence limit. Our general liability page shows how the limits fit together.
Water belongs on an electrician’s list too. Drilling into a supply pipe while fishing wire through a wall is a familiar jobsite loss, and it lands on your liability policy rather than a plumber’s.
DIR certification for the electricians you employ
In California, Labor Code section 108.2 requires anyone who works as an electrician for a C-10 contractor to hold state certification from the Department of Industrial Relations. DIR’s guidance draws the line at connections above 100 volt-amperes. The rule reaches foremen who sometimes work with tools and electricians arriving from other states, who get no grace period.
A few people fall outside it. The qualifying person on the C-10 license does not need a card, and neither does a sole owner who holds the license in their own name. Registered trainees can work only under the constant supervision of a certified electrician. Company principals who never sat the exam for the license still need a card of their own.
This matters for insurance because the CSLB enforces the certification law, and employing uncertified electricians is a violation that can lead to action against the license. Applications ask about it, and an injury or fire claim on a job where an uncertified worker made the connections invites hard questions. Keep a copy of every card with your payroll records.
Solar, EV chargers and battery storage
Solar has a license class of its own. CSLB’s C-46 solar contractor installs, maintains and repairs thermal and photovoltaic systems, and cannot take on other building trades except where the solar installation requires them. A C-10 can install solar as well, and in its battery storage rulemaking the CSLB wrote that there is no dispute that the C-10 scope covers battery energy storage systems.
Workers’ comp treats solar differently from interior wiring. The WCIRB assigns photovoltaic panel installation to class 3724(2), apart from class 5190 for electrical wiring inside buildings, so report the payroll split accurately if your electricians spend part of the year on roofs. Roof work adds fall exposure, and battery and inverter installs add a fire risk that lasts as long as the equipment does.
EV charger work carries a rule of its own. Under Public Utilities Code 740.20, chargers funded or authorized by the CPUC, the California Energy Commission or the state Air Resources Board must be installed by a licensed contractor, with at least one EVITP-certified electrician on each installation. Where a charging port supplies 25 kilowatts or more, at least 25 percent of the electricians on the job must hold that certification. Keep the card numbers in the job file.
Commercial service calls and residential work
Residential work is mostly panel upgrades, added circuits, lighting and troubleshooting in occupied homes, where the exposure is the homeowner’s property and family. Commercial service is a different risk. An outage you cause in a restaurant kitchen or a server room can spoil stock or stop a business for a day, and the owner will look to your policy for the damage and the loss that follows it.
Published insurer guidance notes that commercial work generally costs more to insure than residential work, because of project scale and the higher limits commercial contracts require. Tell us your split by revenue, name your largest commercial clients, and list the kinds of buildings you work in, such as offices, warehouses, schools or medical buildings.
Ladders, lifts and workers’ compensation
Falls from ladders and lifts, shocks, arc flash burns and strains from pulling wire are the exposures a workers’ comp underwriter weighs first for an electrical contractor. California requires workers’ compensation for any employer, even with a single employee, and Cal/OSHA requires every employer to establish and maintain an Injury and Illness Prevention Program. Payroll in class 5190 drives the cost, as the pricing section below works through.
For licensees with no employees, CSLB’s rules are in transition. SB 216 set January 1, 2026 for workers’ comp on every license, and SB 1455 later moved that date to January 1, 2028. Until then, a C-10 with no employees can file an exemption with CSLB, because C-10 is not among the classes barred from it, and the exemption ends as soon as you hire. The workers’ compensation page walks through how electrical payroll is classified.
Vans, tools, the license bond and LLC limits
An electrician’s van carries meters, benders, a cable puller, ladders on the rack and copper wire worth stealing. Commercial auto handles the vehicle and the liability of whoever drives it. The gear and the wire need tools and equipment coverage, which follows them from the van to the job and back.
Your C-10 license also needs the $25,000 contractor’s bond CSLB requires under B&P 7071.6. It answers to consumers harmed by defective work and to employees owed wages, and it pays nothing toward your own losses. An electrical contractor that holds its license as an LLC carries more: at least $1 million of liability insurance for five or fewer personnel of record under B&P 7071.19, another $100,000 for each additional person up to $5 million, and a $100,000 employee/worker bond. See contractor and surety bonds for how those are written.
Umbrella limits on commercial jobs
Commercial contracts often ask for more liability than a primary policy carries. A general contractor or building owner can require $1 million per occurrence on general liability with several million more in total, and an umbrella is how a small electrical contractor reaches that figure. It sits above general liability, commercial auto and employer’s liability, and it applies once one of them runs out.
Check two things before you bind. The umbrella should follow the additional insured and completed operations terms of the policies beneath it, and its limit should match the largest contract you expect to sign this year. Our commercial umbrella page explains the structure, and the contractor insurance guide covers the subcontract terms every trade signs.
What electrician insurance costs
Published industry data shows where small electrical businesses start, and it is not a Mithril1 quote. One national small-business marketplace reports a 10th-percentile price of $20.75 a month and a median of $37 a month for general liability sold to electricians. A second marketplace’s electrician averages, from customers who mostly have fewer than five employees, come to $61 a month for general liability at $1 million per occurrence and $2 million aggregate, $140 a month for workers’ compensation and $275 a month for commercial auto. These describe solo and very small shops at standard limits, and established electrical contractors pay well above them.
The rating basis explains how that grows. General liability follows revenue and payroll, and workers’ comp is priced per $100 of payroll in each classification. The WCIRB’s advisory pure premium rate for class 5190, electricians paid under $40.00 an hour, is $3.729 per $100 of payroll from September 1, 2026. So $200,000 of electrician payroll works out to about $7,458 before the insurer’s expense load, which pure premium rates leave out.
Premiums run higher for commercial and industrial work, solar and battery installs, service-entrance and switchgear work, larger umbrella limits and a history of fire or shock claims. They run lower for residential service and remodel wiring, a clean loss record, electricians who all hold current DIR cards, and higher deductibles. The quote sets the actual price.
A few useful answers
Common questions
Do my electricians need DIR certification if I run a small shop?
Yes, when they work as electricians for a C-10 contractor and make connections above 100 volt-amperes. The license’s qualifying person and a sole owner licensed in their own name are outside the rule, and registered trainees work under a certified electrician’s supervision.
Does general liability respond to a fire caused by wiring I installed last year?
A fire traced to your finished work falls under the products-completed operations hazard of your general liability policy, which answers for injuries and damage to other property. Rewiring your own faulty work is usually left to you.
Is solar work rated the same as other electrical work?
No. For workers’ comp, the WCIRB puts photovoltaic panel installation in its own class, and roof work changes how liability underwriters view the job. Tell us how much of your payroll and revenue comes from solar.
How much umbrella coverage do commercial contracts ask for?
It varies by project. Read the insurance exhibit in each contract and size the umbrella to the largest one you plan to sign, since the limit has to be in force on the day you start.
Do I need workers' comp if I work alone as a C-10?
Under current CSLB rules, a C-10 licensee with no employees can file an exemption until January 1, 2028. After that date the law calls for coverage on every active license, and hiring anyone ends the exemption sooner.
