Electrical contractors carry some of the most serious exposures in the trades. A mistake can start a fire months after the inspector signs off, and a moment of contact with an energized circuit can change a worker’s life. Owners also juggle GC contract requirements, certificates, state licensing and crews spread across several jobs.

This page explains what electrical contracting owners in North Central and Northeast Florida should understand about their insurance, written as education rather than a sales pitch.

What electrical contractors deal with day to day

  • Fire after completion. Faulty connections, overloaded circuits or a missed ground can lead to a fire long after you’ve left the job.
  • Shock and arc injuries. Working near energized parts, temporary power on job sites and lockout failures all create risk for your crew and others.
  • Falls. Ladders, lifts and work at height are part of most jobs.
  • Low-voltage and alarm work. Fire alarm, security and access control systems add a professional side: if a system fails to work, the claim may be about your design or programming, not physical damage.
  • Damage to other trades’ work. Cutting into finished walls, drilling through a water line or damaging a slab.
  • Materials and tools. Copper wire and equipment are frequent theft targets on job sites.

Typical claims in electrical work

Fire damage tied to completed work is the claim electrical contractors worry about most, because it can be large and can surface years later. Property damage during the job, like hitting a water line, is more frequent and smaller. On the workers’ comp side, falls, cuts, strains and electrical contact injuries are the common patterns. Auto accidents with work vans round out the list.

What your contracts ask for, in plain words

Most of the insurance questions electrical contractors face start in a contract, not a policy. Before you sign, read the insurance section and the indemnity section together, because one tells you what you promised to pay for and the other tells you what insurance has to back it up. These are the terms you’ll see most:

  • Minimum limits. The contract lists dollar amounts for general liability, auto, workers’ comp employer’s liability and often an umbrella. Your limits have to meet or beat those numbers on the day you start work.
  • Additional insured. The general contractor or owner wants to be covered under your policy for claims that come out of your work. Many contracts ask for this both while you’re working (ongoing operations) and after the job is done (completed operations), and the endorsement on your policy has to match what the contract says.
  • Waiver of subrogation. After your insurance company pays a claim, it normally has the right to go after whoever caused the loss. A waiver gives up that right against the party named in the contract. It usually takes an endorsement, sometimes on several policies including workers’ comp.
  • Primary and noncontributory. If the contract asks for it and your policy has an endorsement that provides it, your policy pays first for the other party’s covered claim and doesn’t ask their own insurance to share the loss. It isn’t automatic; it takes endorsement wording.
  • Per project aggregate. Some contracts want your general liability aggregate limit to apply separately to each job, so a large claim on one project doesn’t use up the limit for the others.
  • Design responsibility. On design-build or alarm jobs, check whether the contract makes you responsible for design. General liability policies usually don’t cover a pure design error, which is what professional liability is for.

If a contract asks for something your policy can’t do, the time to find out is before you sign. Send us the insurance pages of the contract and we’ll tell you how they line up with your policy and what may need an endorsement. For indemnity and other legal terms, talk with your attorney.

Certificates of insurance: what you’ll be asked for

A certificate of insurance is the one-page summary a GC, owner or property manager asks to see before your crew can start. A certificate is for information only. It doesn’t change or add coverage, which is why careful GCs also ask for copies of the endorsements behind it. Expect requests to show:

  • Policy numbers, dates and limits for general liability, auto, workers’ comp and umbrella
  • The certificate holder’s exact legal name and address
  • Additional insured, waiver of subrogation and primary and noncontributory wording, with the endorsement forms attached when the contract calls for them
  • Workers’ comp coverage, or a copy of the exemption certificate for a qualifying corporate officer or LLC member

Keep one person in your office in charge of certificates, and keep a list of which jobs need updated ones at renewal. You can send requests through our certificate request form.

Workers’ comp for your crew and your subs

Florida treats electrical contracting as construction for workers’ comp. That changes the rules in three ways owners feel directly.

  • One employee is enough. In construction, a business with even one employee has to carry workers’ comp, and an owner who is a corporate officer or LLC member counts unless they’ve filed an exemption. Most non-construction businesses don’t have to until they have four or more employees, full- or part-time.
  • Officer exemptions are narrower. Up to three corporate officers or LLC members who each own at least 10% of the business (three total across affiliated companies) can apply for an exemption through the Division of Workers’ Compensation. It costs $50, lasts two years and is renewed online. An exempt officer or member isn’t covered for their own injuries, so think about health and disability coverage too.
  • You’re responsible for uninsured subs. Under Florida law, if a sub doesn’t have coverage, the contractor above them is treated as the employer of that sub’s workers for comp purposes. That’s why you have to collect each sub’s certificate or exemption before they start, and why it has to stay current for the whole job.

Why audits bring surprise charges

Comp premium starts as an estimate based on the payroll you expect. After the policy ends, the insurance company audits the real numbers. Florida’s audit rules tell auditors to review every source of payment to employees, subcontractors and independent contractors, and to look at the certificates your subs gave you. If a sub can’t show workers’ comp coverage or a valid exemption, Florida law counts the people you paid through that sub as your employees for comp purposes, so the auditor can add those payments to your payroll and charge premium on them. Construction employers large enough to have an experience mod must be audited at least once a year.

Being uninsured is expensive too. The state can issue a stop-work order, and the penalty is two times what the employer would have paid in premium over the prior 12 months, or $1,000, whichever is more.

Report every injury to us or your insurance company right away. Florida requires the employer to report an injury to its carrier within 7 days after learning of it. Read more on our workers’ compensation page.

Your experience mod (EMR): what it is and why GCs ask

If your workers’ comp premium is large enough, your business gets an experience modification factor, often called the mod or EMR. It compares your company’s actual workers’ comp losses with what’s expected for a business of your size doing the same type of work. A mod of 1.00 is average. Below 1.00 is a credit, and above 1.00 is a debit that raises your premium. Small or new businesses that don’t meet the size threshold don’t have one.

Who calculates it in Florida

Florida uses the experience rating plan run by NCCI, the National Council on Compensation Insurance. NCCI calculates the mod, not your agent and not your insurance company. It normally uses three years of payroll and claims, and it leaves out the most recent year before the mod takes effect, because those claims are still too new to judge.

Why it matters when you bid

General contractors, owners and bid packages often ask for your mod, and some use it to prequalify electrical subs before you’re allowed to bid. A mod above 1.00 can keep you off a bid list even when your price is right, because the GC reads it as a sign of how safely you work.

Why frequency usually moves it more than one big claim

The formula weighs the first part of every claim heavily and only part of the cost above that. So a string of small injuries usually raises a mod more than one large one. Under NCCI’s experience rating plan, a medical-only claim (one with no lost-time benefits) generally counts at only 30% of its cost in your mod where NCCI’s Experience Rating Adjustment applies. Report every injury, even small ones. Florida requires employers to report an injury to their insurance company within 7 days of learning of it, and paying a claim yourself instead of reporting it can put you out of compliance and leave the worker without benefits the law gives them. Where the ERA applies, medical-only claims already count at a reduced value in the mod, so there’s little reason to pay them yourself.

What you can do about your mod

  • Run a written safety program that fits your actual work, and hold short, regular crew talks, for example on lockout and tagout, ladder use and temporary power
  • Report every injury the same day, so the claim is handled before costs grow
  • Offer light or modified duty so injured workers can come back sooner, since lost-time claims usually cost more than medical-only ones
  • Ask us for your mod worksheet each year and check it: wrong payroll, a claim that isn’t yours or a closed claim still showing reserves can all push the number up
  • Make sure each employee is in the right class code and your payroll is reported correctly, because the mod is built on those numbers

Vans, tools and equipment

Vans and trucks used for the business should be on a commercial auto policy with every driver listed. If employees drive their own vehicles for work, hired and non-owned auto coverage can respond, subject to the policy’s terms and limits, if your business is held responsible for an accident they cause. The employee’s own auto policy usually pays first, and this coverage doesn’t pay for damage to the employee’s car or protect the employee personally. We explain more in our post on employees driving personal vehicles.

Wire, fixtures and gear stored on site or in a trailer usually need inland marine coverage, because a building policy stops at your shop door. If you own or rent lifts, list them and their values; rented equipment often makes you responsible for damage under the rental agreement.

Florida licensing and bonds

Florida licenses electrical contractors through the Electrical Contractors’ Licensing Board, separate from the board that licenses general and other trade contractors. The board licenses unlimited electrical contractors and alarm system contractors, plus specialty categories set by rule. To be certified, Florida requires proof of workers’ comp coverage or an exemption and public liability and property damage insurance in amounts set by board rule.

Public work over certain amounts requires payment and performance bonds under Florida law, and many cities and counties require permit or license bonds. A bond guarantees your performance or payment to the owner; it isn’t insurance for you. See our bonds page.

See Florida contractor license insurance and bond rules for the minimum amounts, audits and bond rules.

Practical risk management steps

  • Use a written lockout and tagout procedure and make sure each worker has their own lock
  • Test before touching, every time, and treat circuits as live until proven otherwise
  • Inspect extension cords and temporary power daily on job sites
  • Locate and mark hidden lines before cutting or drilling into walls and slabs
  • Photograph rough-in and panels before walls are closed
  • Keep alarm and low-voltage programming records and customer sign-offs
  • Lock up copper and tools at the end of each day

Questions to ask before you renew

  • Does my general liability cover completed operations for the full time a fire claim could be brought?
  • Do I have any design or alarm work that needs professional liability?
  • Do my additional insured endorsements match my largest GCs’ contracts?
  • Are my tool, wire and equipment limits current?
  • What will my experience mod be, and have I checked the worksheet?
  • Are my class codes right, especially for any low-voltage or alarm employees?
  • Is my umbrella limit enough for the commercial work I’m bidding?

Frequently asked questions

Does general liability cover a fire caused by our wiring after the job is finished?

That’s typically a completed operations claim, which contractor general liability policies usually include. Read your policy for exclusions and limits, and make sure completed operations is in place for as long as your contracts require.

Do I need professional liability as an electrical contractor?

If you design systems, do design-build work or program alarm or control systems, you may have exposure that general liability doesn’t cover. Ask us to look at the kind of work you do.

Which board licenses electrical contractors in Florida?

The Electrical Contractors’ Licensing Board, under the Department of Business and Professional Regulation.

How many employees before I need workers’ comp?

Electrical contracting is construction, so one employee is enough in Florida. Qualifying corporate officers or LLC members can apply for an exemption for themselves.

Why does my GC want my experience mod?

The mod shows how your workers’ comp claims compare with similar businesses. 1.00 is average. Many GCs use it to prequalify subs.

What is a waiver of subrogation?

It’s an agreement that your insurance company won’t try to recover what it paid from the party named in your contract. It’s usually added by endorsement.

Is wire stored on a job site covered?

Usually not under a building policy. Inland marine or builders risk coverage, depending on the contract, is how materials at a job site are normally covered.
