There is no honest flat number for a solo electrician's general liability premium — carriers price it on your revenue and payroll, the limits you buy, your mix of work, and your claims history, so two solos in the same county can pay very different amounts. What you control is the structure: buy the per-occurrence and aggregate limits your contracts demand, keep your classification accurate, and shop through an agent who writes trades. Anyone quoting an 'average cost' without asking your revenue is guessing.
Every solo electrician googles "how much is GL insurance" and lands on pages that confidently print a number. Here's the uncomfortable truth from someone who's bought this coverage for fifteen years: the number is made up. Not because premiums are secret, but because yours is built from inputs those pages don't have. So instead of a fake number, here's the machine that produces the real one — and the certificate logistics that matter more than the premium once you're taking sub work.
What the premium is actually built from
- Exposure base — usually your revenue and payroll. GL for trades is typically rated on gross receipts and/or payroll. Bigger book, bigger premium. This is also why the number scales with you instead of being a flat fee.
- The limits you buy. Per-occurrence and aggregate limits are the biggest structural choice; higher limits, higher premium — though rarely proportionally.
- Work mix. Residential service and repair prices differently than new construction, commercial, or anything structural. Carriers ask exactly what you do; answer precisely, because the classification drives the rate and a wrong one bites at audit or, worse, at claim time.
- Subcontracting, in both directions. Whether you hire subs, and how much of your revenue comes from working as one, both show up on the application.
- Claims history and years in business. A clean record and a track record both earn better pricing; a fresh entity with no history pays for the uncertainty.
Two takeaways. First, when a solo asks "what do you pay?" at the supply house, the answer tells him almost nothing — different revenue, different mix, different limits. Second, the inputs are levers: an accurate (not padded) revenue estimate and a precisely described work mix are the legitimate ways to avoid overpaying.
The structure: what you're actually buying
A GL policy quotes two headline numbers: the per-occurrence limit (the most the policy pays for a single incident) and the aggregate limit (the most it pays across the policy year). In my experience the boilerplate ask on sub agreements and commercial work is $1 million per occurrence with a $2 million aggregate — read your own contracts, because the requirement lives there, not in any statute. Beyond the limits, ask your agent to walk you through exclusions that matter for electricians — care/custody/control of the customer's property, damage to your own completed work, anything touching new construction if that's in your mix. This is exactly the "how it generally works" territory where your agent's answer beats any blog post, including this one.
The audit: the bill after the bill
Because the premium is rated on revenue, it starts as an estimate and gets trued up. A labeled hypothetical to show the shape: say you bind a policy estimating $150,000 of receipts, and the year goes well — you actually do $250,000. At audit the carrier recalculates on the real number and sends an additional premium bill for the difference. Nothing went wrong; that's the design. Budget for it in a growth year, keep clean books so the audit is fast, and don't lowball the estimate on purpose — you're not saving money, you're deferring an invoice and irritating the underwriter.
Certificate logistics: the part sub work actually runs on
Once you take subcontract work, the document that matters day to day isn't the policy — it's the certificate of insurance (COI), the one-page proof your coverage exists. The requests that come with it:
- Additional insured. The GC or hiring party asks to be named on your policy for the work you do for them. Standard ask; your agent handles it via endorsement.
- Primary and noncontributory / waiver of subrogation. Common contract wording that changes whose policy responds first and who can chase whom afterward. Don't sign contracts promising endorsements your policy doesn't have — hand the insurance section to your agent before you sign, not after.
- Speed. The COI request always lands the day before mobilization. Before you bind coverage, ask the agent one question: "How fast can you issue a certificate naming an additional insured?" If the answer isn't "same day," keep shopping.
This is also where networks live. At Loadside, verified insurance is part of the bar for joining — one certificate up front, and then you never re-prove it job by job the way you do bidding to a new GC every month. It's one of the quiet ways a job network differs from a lead platform: the platform sells you an introduction and leaves the paperwork dance to you; the network does the vetting once, on both sides.
How to shop it without getting soaked
- Use an independent agent who writes trades. Contractors' GL is a specialty; an agent who insures electricians and plumbers all day knows which carriers actually want your class of work this year.
- Get quotes on identical specs. Same limits, same classifications, same revenue estimate — otherwise you're comparing noise.
- Ask about a package. A business owner's policy or package that bundles GL with tools coverage (inland marine) can beat separate policies. Remember GL covers neither your tools nor your truck — those are inland marine and commercial auto, and the truck one is not optional to get right.
- Re-shop at renewal when something changed. Revenue jumped, mix shifted, a claim aged off — that's when the market moves for you.
Where this sits in the bigger picture of running your shop — licensing, workers' comp, pricing, pipeline — is the pillar post: running a one-truck shop in Northern Virginia.
The standing caveat: this is how contractor GL generally works, written by an electrician who buys it — not insurance advice. Your policy's actual terms and your state's actual requirements come from your agent and the official sources, in that order.
