How to Value an Electrical Contracting Business

A buyer doesn't pay for the electrical contracting business you built. They pay for the cash flow they can defend after the truck has a new name on it — and for how little of it walks out the door with the master-electrician license, the key GC relationships, and you. So when an owner asks how to value an electrical contracting business, the honest answer is a two-line formula and a long list of judgment calls a buyer's analyst is going to make from your QuickBooks file.

This is the buyer's-eye version of that math for an electrical shop — plain, with the real ranges the offers.ai engine uses for electrical, and no invented numbers.

The formula every buyer is running

Value = normalized earnings × a multiple. Two levers, every argument on an electrical deal is about one of them.

• Normalized earnings. Your profit, rebuilt the way a buyer's analyst will rebuild it: a market-rate wage for you in place of your owner draw, personal spending stripped out, one-time costs removed, the service van that's actually for the business separated from the family vehicles. For most owner-run shops the resulting number is SDE (seller's discretionary earnings); for larger, manager-run companies it's EBITDA. The gap between the two is wide enough to merit its own walkthrough.
• The multiple. How many years of those earnings a buyer pays at close. It's set mostly by company size, by how repeatable and owner-independent the revenue is, and — on electrical especially — by your project-versus-service mix and your license picture.

Get either lever wrong and the number moves more than a full year of growth you fought for.

How to value an electrical contracting business: the band

Electrical service businesses transact inside the broader industrials × construction/maintenance category. Blending recent lower-middle-market closings, main-street broker sales reports, and a private-capital-markets survey, electrical shops trade in roughly this band on normalized EBITDA:

That range is what the offers.ai engine returns for electrical — the same number behind the electrical overview and the diagnostic. The very top of the band shows up in small samples but isn't representative for an owner-operated shop; don't anchor on it.

Now put earnings on the band. Illustrative: an electrical contractor with about $3M in revenue and ~$500K of adjusted EBITDA (~17% margin, project-and-service mix):

The same earnings are worth roughly $1.25M to $4.0M depending on where the company actually lands inside the band. That spread isn't luck — it's the value drivers below, and they're things you can move with 12–24 months of intent.

Smaller, owner-operated electrical shops priced on SDE (the main-street tier) sit at the lower end and below the EBITDA band — that's normal, not a slight. The whole point of the work between now and a sale is to migrate up.

Why the spread is so wide on electrical

Two facts about the trade do most of the work. First, electrical skews project-led. The engine's electrical benchmark for recurring revenue is ~15% of revenue — structurally lower than HVAC (~30%) or plumbing (~25%) — because so much of the work is new construction, build-out, or one-off commercial projects. That's a floor a buyer expects on an electrical book; the shops that clear it materially are the ones that earn the higher end of the band.

Second, electrical is more license- and owner-dependent than most trades. The master electrician's license, the estimating, and the key commercial relationships often all sit with the same person — you. A PE-backed buyer with their own qualifier on bench discounts that less, but pays less for the privilege. A search-fund or SBA-backed individual buyer can't backfill the license from a bench and underwrites the whole deal on whether the business survives your exit. Both of those buyers can be the right buyer; they just price different.

Here is what each of the three value drivers the engine scores for electrical is typically worth — illustratively, at the representative ~$500K-EBITDA shop. Your real number comes from your own books.

For reference, the electrical benchmarks the engine prices against. The further you sit from them, the more a buyer discounts.

What this means in dollars for your shop

Stack two of those drivers — a real service-contract or monitoring book and a second qualifying license-holder with documented estimating — and on a $500K-EBITDA business you are plausibly moving the price $250K–$450K, before adding a dollar of new revenue. That's the case for spending 12–24 months getting buyer-ready instead of grabbing the first unsolicited offer from a roll-up. If those calls have started, you're not alone — the smart move is to decide what your number is before you answer one.

The arithmetic is mechanical. At ~$500K of EBITDA, every 0.1× of multiple is about $50K of enterprise value. A 0.3×–0.5× lift on the license-and-people lever is $150K–$250K of value for solving the single biggest single-point-of-failure on an electrical book. Inside the same band, a customer-concentration problem can travel in the opposite direction — see how one GC relationship re-prices a deal for the long version.

For the full inventory of these levers across trades — and the language buyers actually use to discount them — the value-drivers overview is the umbrella read.

Common mistakes that cost electrical owners a turn

The buyer's playbook on an electrical book has a few familiar moves. Know them before diligence runs you over with them.

• Treating tenure as diversification. "We've worked with this GC since '02" is real and valuable, but it isn't the same word as a diversified book. Above the ~30% top-customer line on an electrical file, expect concentration to come out of the multiple — and sometimes out of the structure as an earn-out tied to that GC's retention.
• A business that's really just you and the license. If the master license, the estimating, and the largest commercial accounts are all you, a search-funder or SBA-backed buyer is underwriting whether the business survives your exit and discounts heavily for it. A second qualifier, a written estimating playbook, and retention plans for your key field leaders convert "key-man risk" into a manageable transition.
• Calling project repeat "recurring." A GC who hires you on three projects a year is repeat. A property manager paying you monthly for preventive maintenance and panel checks is recurring. A buyer pays a premium for the second and discounts the first. Against the ~15% electrical floor, every point of true recurring lifts the read.
• Margins below the benchmark with no explanation. Gross margin around 28% and EBITDA margin around 10% are what a healthy electrical book looks like. Sustained shortfalls usually trace to estimating drift or change-order leakage — a buyer prices both as risk and opportunity, and the opportunity accrues to them unless you capture it before the sale.
• A capex story you haven't documented. Trucks, bucket vans, lift gear, test equipment, and stocked inventory all wear out. A buyer normalizes maintenance capex to the replacement level — usually in the 1.5–3% of revenue range for electrical — and assumes a refresh bill early in the hold. Without a documented equipment-age and replacement plan, they assume the worst and take it off the cash flow they're paying for.
• Add-backs a buyer won't accept. Adding back your full salary when nobody else can do your job isn't an add-back; it's the real cost of running the business and a clean QoE will pull it back into EBITDA. The same goes for "one-time" items that turn up every other year.
• Quoting yourself the high end. ~8× is a manager-run electrical platform with a deep service book, a transferable license picture, and diversified customers. An owner-operated shop priced on SDE sits closer to the bottom of the range. Be honest with yourself before a buyer is.

The takeaway

How to value an electrical contracting business? Normalized earnings × a multiple that runs about 2.5×–8.0× on EBITDA, typically near 5.0× — and you control most of what sets that multiple. A service or monitoring book that clears the ~15% recurring floor, a transferable license picture and a real management layer between you and the work, customers spread under the ~30% top-customer line, and clean buyer-grade books are the levers. The number isn't fixed until you sign; the 12–24 months before you do are where it's actually decided.

This is exactly the read offers.ai produces from your real QuickBooks file — your normalized EBITDA, your project-vs-recurring split, your largest-customer share, your equipment-replacement story, and the value drivers the engine scores against the electrical benchmark.
