How to Bid Electrical Jobs (Without Leaving Money on the Table)

A good electrical bid does two jobs: it wins the work you want, and it makes money on the work you win. Most contractors who struggle are good at one and not the other. They either bid tight to win and lose money in the field, or they bid safe and win only the jobs nobody else wanted.

To bid an electrical job, decide whether the job is worth chasing, read the whole bid package, take off every item, price material and labor at your burdened rate, add job costs, overhead and margin, then send a proposal with clear exclusions and follow up. This guide walks through each step the way experienced estimators do it, then works a residential and a commercial bid with real numbers you can compare against your own.

Step 1: Decide whether to bid

The most profitable bids are often the ones you don't submit. Before spending hours on a takeoff, answer these questions:

• Is it your kind of work? Service-upgrade specialists who bid a hospital wing are guessing.
• Who's the customer? Check the GC or owner's payment history. Slow pay can erase your margin.
• How many bidders? Ten bidders on a public job is a price war. Three invited bidders is a relationship.
• Can you staff it? Winning a job you can't man costs more than losing it.
• Is there enough time to bid properly? A rushed bid is a risky bid.

Track your hit rate by customer and job type. If you win 5% of a GC's invitations, the relationship may not be worth the estimating hours. The guide to finding electrical jobs to bid has a bid/no-bid scorecard and the math on what each estimate costs you.

Step 2: Read the whole bid package

Scope hides everywhere. Read:

• Electrical drawings and specifications (Division 26, plus 27 and 28 if low-voltage and fire alarm are included).
• Mechanical, plumbing and architectural sheets. Equipment connections, water heaters, pumps, motorized doors, signage and kitchen equipment often appear only there.
• Addenda. Missing an addendum is one of the most common bid disqualifiers.
• General conditions: bonding, insurance, retainage, liquidated damages, schedule, working hours.

Write down every question, and submit RFIs before the deadline. Note anything unclear as a clarification or exclusion in your proposal.

On larger jobs, also check the spec sections that quietly add cost: approved manufacturers (no substitutions means no cheaper fixture package), testing and commissioning requirements, as-built and O&M manual requirements, temporary power and lighting responsibility, and who furnishes and who installs owner-provided equipment. Each one is a line in your estimate or a line in your exclusions. It should never be neither.

Step 3: Do the takeoff

The takeoff is the count of everything you'll install:

• Devices: receptacles, switches, data outlets, by type.
• Lighting: fixtures by schedule tag.
• Distribution: panels, transformers, disconnects, switchboards.
• Branch circuits and feeders: home runs, conduit and wire lengths, by size.
• Equipment connections, fire alarm, low voltage, and temporary power if included.

Count by area or floor so you can check your work and so the field can use it later. Digital takeoff tools let you click or auto-detect symbols on the PDF, which is faster and leaves a record of what you counted. See how to estimate electrical work for a room-by-room takeoff checklist, and electrical takeoff software for how automated counting works.

Mark every counted symbol on the plans (a highlighter on paper, a color on the PDF). The uncounted symbols that remain are your missed scope.

Step 4: Price materials

Apply current supplier prices to every item. Copper prices move, so date your quote and send the material list to at least two suppliers on large jobs. Add waste: typically 5–10% on wire and small parts, less on counted devices.

Get lighting and gear quotes in writing, and read what they exclude: lamps, drivers, freight, lead time and quote expiry. On bid day, a switchgear quote that expires before the award date is a risk you are carrying for free.

Step 5: Calculate labor

Labor is the biggest risk in an electrical bid, typically a third to a half of the total. Use:

• Labor units: hours per item, from your own job-cost history or a published source like the NECA Manual of Labor Units. See NECA labor units explained.
• Adjustments: height, access, existing conditions, occupied buildings, weather, overtime and learning curve on repetitive work.
• Labor rate: your burdened cost per hour, including payroll taxes, workers' compensation, benefits, and non-productive time. Not the wage.
• Supervision: foreman time is usually priced on top of installation units, either as a percentage of labor or as the foreman's hours across the schedule.

Step 6: Add job costs, overhead and profit

• Direct job costs: permits, equipment rental (lifts, trenchers), dumpsters, temporary facilities, travel, bonds.
• Overhead: your share of office, trucks, insurance, software, and management salaries. Know your real overhead as a percentage of revenue from last year's books.
• Profit: price by margin, not markup. A 20% margin requires a 25% markup on cost. Use the electrical bid calculator to check the math, and the profit margin guide to set the target.

Step 7: Write the proposal

A clear proposal wins more jobs at the same price. Include:

• Scope summary, drawing and addenda list you bid from.
• Price, with alternates and unit prices if requested.
• Inclusions, exclusions and clarifications (for example: "Excludes utility company charges," "Excludes patching and painting," "Assumes existing panel is in serviceable condition").
• Schedule assumptions and payment terms.
• Validity period (copper pricing makes 30 days common).

Use the electrical bid proposal template as a starting point. It includes sample exclusion, escalation and change-order wording.

Step 8: Follow up and learn

Call after the bid opens. Ask where you landed and why. Log every result: job type, customer, your number, the winning number if known, and your estimated vs. actual hours on jobs you won. That record is how your next bid gets better.

Worked example 1: residential kitchen remodel

A homeowner is remodeling a kitchen with the walls open to the studs. Scope: 5 new circuits with home runs, 6 countertop receptacles, 8 recessed lights, under-cabinet lighting, 4 switches and dimmers, and panel terminations. Illustrative units and prices; use your own.

• Labor: 22 hours × $52 burdened = $1,144
• Material, including waste: $1,180
• Permit: $175
• Direct cost: $2,499
• Overhead at 22% (residential remodel carries more drive time and small-job overhead): $2,499 × 1.22 = $3,048.78 break-even
• Price at a 20% target margin: $3,048.78 ÷ 0.80 = $3,810.98, quoted at $3,850, which yields a 20.8% margin.

The homeowner sees one price with a clear scope and exclusions (patching, fixture selection above an allowance, any panel replacement found necessary). The electrical bid calculator walks through a second residential example, a basement finish, with the same method.

Worked example 2: small commercial tenant fit-out

A 4,000 ft² office tenant improvement. Scope: new lighting and controls, receptacles, data rough-in, one new 225 A panel fed from existing switchgear, HVAC equipment connections.

Rounded up, the bid is $78,430. If the job runs 10% over on labor (41 hours, or $2,542), the margin falls to about 9.5%. That sensitivity is why labor units and job-cost tracking matter more than any other part of the process.

Check your number before you submit

Before the price goes out, run it through a few sanity checks. None of them proves the estimate is right, but each one catches a class of error.

Compare each ratio with your own completed jobs of the same type, not with a number from someone else's market.

Bid-day checklist

Commercial bids are usually due at a fixed hour, and the last few hours are when mistakes happen. Work through this list the day before, then again once late quotes arrive:

1. All addenda received, read, priced and acknowledged by number.
2. Every material quote received, dated and valid past the expected award date. Missing quotes replaced with a documented plug number.
3. Labor extended and adjusted; supervision included once, not twice.
4. Job costs checked: lifts, permits, bonds, temporary power, dumpsters, parking, travel.
5. Overhead and margin applied; final number rounded and entered on the GC's bid form exactly as requested (lump sum, breakouts, alternates, unit prices).
6. Exclusions and clarifications reviewed against the bid form. Some GCs reject qualified bids, so know which exclusions you can defend.
7. Bond, insurance certificate and any required forms attached.
8. Proposal sent early, with a call or email to confirm receipt.

How GCs compare your number

On commercial work, the GC's estimator levels the bids: they put every electrical number side by side and adjust for scope differences. If your exclusions remove fire alarm and a competitor's number includes it, the GC will add a plug for fire alarm to your price before comparing. That means a vague exclusion can make your bid look higher than it is, and a missing exclusion can win you work you didn't price. A clean scope sheet that matches their bid form is the easiest way to be compared fairly.

Pricing alternates and unit prices

Alternates and unit prices are often decided after the award, when you have less leverage, so price them as carefully as the base bid.

• Add alternates: estimate the added scope in full (material, labor, overhead, margin). Don't discount them to look competitive; the GC compares base bids, and alternates are often accepted later.
• Deduct alternates: credit only what you actually save. Removing half the fixtures doesn't remove half the mobilization, supervision or panel work.
• Unit prices: build them from a labor unit, material and your markup, and state what's included (for example, "per duplex receptacle including up to 20 feet of branch circuit"). The NECA labor units guide shows how a per-fixture unit price is built up.

Change orders and T&M pricing

Winning the job is half the money. The other half is getting paid for changes. Price change orders with the same method as the base bid, and at least the same margin, because changes disrupt the schedule and carry more risk per hour.

Example: 8 added receptacles in a finished office. Old-work installation with fishing, illustrated at 0.9 hours each: 8 × 0.9 = 7.2 hours × $62 = $446.40. Material at $38 each: $304. Direct cost $750.40, plus 18% overhead = $885.47, divided by 0.85 for a 15% margin = $1,041.73.

When the scope can't be defined upfront, work time and material (T&M) at rates agreed in the contract. The same cost structure gives a T&M labor rate: $62 burdened × 1.18 overhead ÷ 0.85 = $86.07 per hour before any premium for overtime. Get a signed T&M ticket every day, listing workers, hours and material, or the change is just an argument later.

Residential vs. commercial bidding

Common bidding mistakes

• Bidding from the electrical sheets only.
• Using wage instead of burdened labor cost.
• Applying margin as markup.
• No exclusions, so every surprise becomes free work.
• Not tracking estimated vs. actual hours.
• Holding a copper price for 90 days.
• Carrying supervision twice (in the units and again as a percentage), or not at all.
• Accepting a GC's contract terms (retainage, pay-when-paid, liquidated damages) without pricing them.

Frequently asked questions

How do you calculate an electrical bid?

Material cost + labor (hours × burdened rate) + direct job costs = direct cost. Add overhead to reach break-even, then divide by (1 − target margin) to get the price.

How much should an electrician charge per outlet?

HomeGuide's homeowner pricing guide (updated February 11, 2026) lists $140–$165 to install a new conventional outlet and $120–$150 to replace one with a GFCI; hard access and old-work installs cost more. Build your own number from your labor units and cost structure.

How long does it take to bid an electrical job?

A residential service quote can take minutes. A commercial tenant improvement can take one to three days of estimating. Takeoff is usually the largest share of the time.

What should be excluded from an electrical bid?

Common exclusions are utility company fees, patching and painting, trenching in rock, permits (if the owner pulls them), fire alarm or low voltage if not in scope, and work not shown on the drawings you bid from.

How do you price an electrical change order?

Estimate it like a small bid: labor hours from your units (adjusted for working in finished or occupied space), material, overhead, and at least the base-bid margin. Get it signed before the work starts, or track it on daily signed T&M tickets.
