How to price and bid commercial electrical work

Commercial electrical bids can get complicated fast. The scope is bigger, the drawings are more complex, and one missed detail can wipe out your margin. If you’re pricing a job right now, you need a number that’s competitive and still leaves room for profit.

That means starting with the plans, specs, and site conditions, then building the price around the labor, materials, equipment, overhead, and risk the job actually requires. This guide walks you through that process step by step.

Quick answer: How do you price commercial electrical work?

To price commercial electrical work, start with the project scope, then add burdened labor, materials, equipment, subcontractors, project overhead, your share of company overhead, and contingency. Divide that total cost by one minus your target profit margin to get the selling price.

Price the job from the actual scope of work, not a square-foot shortcut.

How we sourced commercial electrical pricing data

Because commercial electrical projects vary so widely by scope, building type, equipment, and contract terms, this guide doesn’t use one national average price list. The most useful pricing benchmark is the estimate built from your actual labor, material, overhead, and risk.

We sourced additional data from public wage data and industry estimating guidance. The labor benchmark comes from the U.S. Bureau of Labor Statistics (BLS), while the estimating workflow and labor-unit guidance come from the National Electrical Contractors Association (NECA).

Actual pricing varies based on:

• Local wages and prevailing-wage requirements
• Material and equipment costs
• Project size and complexity
• Access, scheduling, and site conditions
• Insurance, bonding, and contract requirements
• Company overhead and target margin

The examples included are only to show how the math works. Use them to check your estimating process, then replace every input with your actual costs.

How commercial electrical pricing differs from residential pricing

Residential electrical work is often priced using flat rates for a specific task, such as replacing an outlet, installing a ceiling fan, or upgrading a service panel.

Commercial electrical work is usually priced from construction plans, written specifications, site conditions, schedules, and contract requirements. Even relatively small commercial projects can require a formal material takeoff, vendor quotes, labor-unit calculations, bid alternates, insurance documentation, and coordination with a general contractor.

Residential electrical work	Commercial electrical work
Often priced by task	Frequently priced from plans and specifications
Usually has a short sales cycle	May involve a formal bidding and approval process
Typically involves smaller material orders	May require major equipment and bulk purchasing
Usually has one primary customer	May involve an owner, general contractor, architect, and engineer
Often has fewer contract requirements	May include retainage, bonds, and strict payment terms
Usually involves limited trade coordination	Requires coordination with multiple contractors
Often completed in one visit	May take weeks or months to complete

Commercial jobs may also expose your business to costs that don’t appear on a residential service invoice. For example, a tenant-improvement job in an occupied office may require night work, lift delivery, daily cleanup, security check-in, and phased shutdowns.

Common commercial electrical pricing models

The right pricing model depends on how clearly the job’s scope can be defined and how much risk your company is willing to take.

Lump-sum pricing

A lump-sum bid gives the customer one fixed price for the complete scope described in the proposal.

This model works best when the drawings and specifications are complete enough for you to perform a reliable takeoff. Your proposal should state which documents you used, what’s included, what’s excluded, and how long the price remains valid.

Under a lump-sum bid, your company usually absorbs estimating misses and productivity overruns unless the scope or contract requirements change.

Time-and-materials pricing

With time-and-materials pricing, the customer pays for the labor hours and material used to complete the work. Materials are generally billed at cost plus a predetermined markup.

This approach works well for troubleshooting, repairs, emergency calls, maintenance, and projects where the exact scope can’t be determined before work begins.

Your agreement should define labor rates, minimum charges, overtime rates, material markup, equipment charges, and any customer-authorization limit.

Unit pricing

Unit pricing gives you one standard price for each measurable piece of work, such as:

• Each receptacle installed
• Each lighting fixture replaced
• Each foot of conduit
• Each circuit added
• Each equipment connection
• Each data drop
• Each fire alarm device

Unit pricing works well on repetitive jobs or projects where quantities may change. You can also use it alongside a lump-sum bid to set prices for additions or deductions.

However, the unit price has to cover more than the visible install. Include supports, fittings, wire, testing, supervision, access equipment, waste, and other related costs.

Cost-plus pricing

With a cost-plus arrangement, the customer pays the documented project costs plus an agreed fee or percentage.

This model can work when the scope is still changing, but it depends on accurate job-cost records. Track labor hours, supplier invoices, equipment charges, subcontractor bills, and the agreed contractor fee separately.

Spell out which expenses the customer will repay and whether your fee applies to subcontractors, equipment, permits, and other categories.

Commercial service agreement pricing

Commercial service agreements are typically priced as monthly, quarterly, or annual contracts.

The contract may include:

• Scheduled inspections
• Preventive maintenance
• Priority response
• A set number of labor hours
• Discounted service rates
• Thermal imaging
• Emergency-lighting tests
• Panel maintenance
• Electrical-system documentation

Clearly state what’s included, how unused hours are handled, and which repairs or after-hours calls will be billed separately.

Plan-and-spec vs. design-build pricing

Plan-and-spec bids price a design that has already been developed by an architect or engineer. Your job is to estimate the labor, materials, equipment, and other costs required to build that documented scope.

Design-build estimates may also need to cover engineering, design development, code coordination, owner selections, and scope changes. Because you’re pricing before every design decision is final, design-build work usually needs clearer allowances, milestones, and change-management terms.

How to estimate a commercial electrical job

A repeatable electrical estimating process makes it easier to submit bids quickly without leaving major costs behind.

Step 1: Review the plans, specifications, and bid documents

Start by identifying every document that controls the project.

These may include:

• Electrical plans
• Architectural plans
• One-line diagrams
• Panel schedules
• Fixture schedules
• Equipment schedules
• Written specifications
• Bid instructions
• Addenda
• General conditions
• Project schedule
• Insurance requirements
• Bonding requirements
• Prevailing-wage requirements
• Contract terms

Check the issue date and revision number on every document. A bid based on an outdated drawing set can miss major additions or include work that’s already been removed.

Don’t limit your review to the electrical sheets. Architectural, mechanical, plumbing, kitchen-equipment, and reflected-ceiling plans may show connections or installation conditions that aren’t clearly identified on the electrical drawings.

Pro tip: Create a bid-document checklist and record the date of every drawing and addendum used. Include those dates in your final proposal.

Step 2: Define the scope, assumptions, and exclusions

Before you begin counting material, write down what you believe the project includes.

Confirm responsibility for items such as:

• Demolition
• Temporary power
• Utility coordination
• Trenching and backfill
• Core drilling
• Concrete pads
• Firestopping
• Patching and painting
• Ceiling removal and replacement
• Low-voltage wiring
• Fire alarm
• Data and communications
• Security systems
• Equipment controls
• Permit fees
• Testing and commissioning
• Off-hours work
• Cleanup and disposal

When a responsibility isn’t clear, submit a request for information when the bidding process allows it. When the answer won’t arrive before the bid deadline, state your assumption in the proposal.

For example:

This proposal is based on the electrical drawings dated [date] and specifications issued [date]. Pricing excludes work not shown in those documents unless specifically identified as an allowance or alternate.

Assumptions don’t eliminate all risk, but they make it easier to show what your price was based on if the scope changes later. If the general contractor is open to cost-saving substitutions, this is also the stage to flag them. 

Step 3: Complete the material takeoff

A material takeoff identifies the quantities needed to complete the job.

Depending on the project, your takeoff may include:

• Switchgear
• Panels
• Transformers
• Disconnects
• Feeders
• Branch circuits
• Conduit and raceway
• Wire and cable
• Junction boxes
• Fittings
• Supports and hangers
• Lighting fixtures
• Lighting controls
• Receptacles
• Switches
• Grounding materials
• Equipment connections
• Fire alarm devices
• Communications equipment
• Identification and labeling

How to perform a commercial electrical takeoff

Use the same basic sequence on every bid:

1. Lock the takeoff set: Record the drawing dates and addenda so later revisions don’t get mixed into the count.
2. Divide the project into sections: Organize the takeoff by system, floor, room, building area, or drawing.
3. Count equipment and devices: Record fixtures, panels, receptacles, controls, disconnects, and other individual items.
4. Measure raceway and conductor runs: Account for routing, elevation changes, bends, home runs, and vertical risers.
5. Apply assemblies and pricing: Add fittings, supports, waste, labor units, and current vendor prices.

Remember to include small material. Connectors, straps, bushings, couplings, fasteners, wire nuts, labels, and other minor components can add up across a large job.

Get supplier quotes for major equipment instead of relying on remembered prices. Record the quote date, freight terms, lead time, taxes, and expiration date.

Pro tip: Price major equipment separately from everyday material. A lower markup percentage may still produce enough gross profit on a large switchgear package, while fittings and consumables may need a higher percentage because purchasing, handling, loss, and warranty costs are larger relative to the item price.

Step 4: Estimate the labor hours

Labor is usually one of the largest and least predictable costs, though switchgear, fixtures, and specialty equipment may dominate some projects.

Start by assigning labor units to the quantities in your takeoff. A labor unit estimates how long a standard installation should take under defined conditions. The NECA Manual of Labor Units is an experience-based reference for estimating common electrical and communications installations.

A labor unit is a starting point, not a guarantee. Adjust your hours based on the conditions of the project.

Common productivity factors include:

• Working height
• Congested ceilings
• Occupied spaces
• Restricted work hours
• Limited loading or parking
• Long material-carrying distances
• Security procedures
• Weather exposure
• Phased construction
• Crew experience
• Repetitive work
• Trade stacking
• Schedule acceleration
• Poor access to electrical rooms
• Renovation work with hidden conditions

For example, installing identical fixtures across an open warehouse may be faster than installing the same quantity above finished ceilings in an occupied medical office.

A retail project limited to overnight shifts may also require overtime, daily cleanup, and repeated setup and breakdown.

Account for crew composition too. A crew made up entirely of journeymen has a different cost and production rate than a balanced crew of journeymen and apprentices.

Step 5: Calculate your burdened labor cost

An employee’s hourly wage isn’t the complete cost of their labor.

Your burdened labor cost may include:

• Base wage
• Employer payroll taxes
• Workers’ compensation
• Health insurance
• Retirement contributions
• Paid time off
• Training
• Bonuses
• Uniforms
• Other employee benefits

Use this formula:

Burdened hourly labor cost = base wage + payroll taxes + workers’ compensation + benefits + other labor-related costs

Then calculate the project’s direct labor cost:

Estimated burdened labor cost = total labor hours × burdened hourly labor cost

The Bureau of Labor Statistics (BLS) reported a median electrician wage of $63,190 per year, or $30.38 per hour, in May 2025. This is the rate businesses pay electricians on average, not what you should charge customers.

Use local wage information whenever possible. CareerOneStop’s Salary Finder lets you compare local pay with state and national data from the BLS.

Calculate a blended crew rate

A blended crew rate combines the burdened costs of the different workers you expect to use on the project.

Multiply each worker type’s burdened hourly rate by their expected share of the crew’s labor hours, then add those amounts together.

For example, suppose a two-person crew includes:

• One journeyman with a burdened rate of $52 per hour
• One apprentice with a burdened rate of $32 per hour

If they’re expected to work equal hours:

Blended crew rate = ($52 × 50%) + ($32 × 50%) = $42 per labor hour

Use the actual crew mix you expect to send. Don’t price every labor hour at the journeyman rate when apprentices will complete part of the work, and don’t assume apprentice-level costs when the job requires more experienced electricians.

Adjust for prevailing-wage and union requirements

Prevailing-wage, union, and public-works requirements can increase both your labor costs and paperwork.

Check for:

• Required wage determinations
• Fringe-benefit requirements
• Apprentice ratios
• Union jurisdiction rules
• Certified payroll reporting
• Travel or subsistence requirements
• Payroll record-retention requirements
• Penalties for noncompliance

Use the wage determination and contract documents that apply to the specific project. Don’t rely on rates from a previous public project, even when the job is in the same region.

Include the office time needed to prepare certified payroll records and manage compliance. You may charge that time to project overhead rather than direct installation labor, but it still belongs in the estimate.

Step 6: Add materials, equipment, and subcontractor costs

Start with the full landed cost of the material, not just the supplier’s base price.

That may include:

• Material cost
• Sales tax
• Freight
• Delivery
• Storage
• Waste
• Price escalation
• Expediting
• Procurement time
• Handling
• Warranty exposure

Then add the equipment the job needs, such as:

• Scissor lifts
• Boom lifts
• Trenchers
• Generators
• Temporary lighting
• Scaffolding
• Testing equipment
• Material-handling equipment

Bring in subcontractor quotes for work like engineering, excavation, concrete, fire alarm, controls, testing, or other specialty services. Make sure you know exactly what each quote includes, including permits, mobilization, overtime, closeout documents, and bonding.

Line supplier and subcontractor quotes up side by side so you’re comparing the same things: taxes, freight, controls, startup, permits, and exclusions.

Check whether permit, plan-review, utility, and reinspection fees are fixed costs, customer-paid costs, or allowances. Don’t assume the general contractor or owner is covering them unless the bid documents say so.

On tax-exempt projects—schools, government buildings, and some nonprofit work—confirm whether the exemption applies to materials, and get the exemption certificate in writing before you bid. Pricing a job as taxable when it’s actually exempt (or the reverse) directly affects your margin.

Step 7: Add project overhead

Project overhead includes costs that support the job but aren’t part of the installation itself.

That can include:

• Project management
• Field supervision
• Mobilization
• Safety meetings
• Temporary facilities
• Parking
• Travel
• Jobsite storage
• Cleanup
• Small tools
• Permit administration
• Submittals
• As-built drawings
• Operation and maintenance manuals
• Testing coordination
• Closeout documentation
• Bond costs

Add these costs up for the job, then include that total directly in the bid or spread it across your estimated labor hours, depending on how you build your prices.

Note: Project overhead is different from general company overhead. That’s the cost of running your business, like office rent, software, insurance, bookkeeping, advertising, and admin payroll. You need to account for both in your price.

Step 8: Add contingency for project risk

Contingency is money included to cover any risk your company is responsible for.

You may need contingency when:

• The design is incomplete.
• Existing conditions are concealed.
• The building will remain occupied.
• Material prices may change before purchase.
• Equipment lead times are uncertain.
• The schedule is compressed.
• Work must be completed in phases.
• Utility requirements haven’t been confirmed.
• Feeder routes aren’t fully shown.
• Access is limited.
• Other trades may affect your productivity.

Don’t tack on the same contingency price for every job. List the real risks, estimate the impact, and build the contingency from there.

Step 9: Add your target profit

Once you’ve added your burdened labor, material, equipment, subcontractor, job overhead, company overhead, and contingency costs, apply your target profit margin.

Use this formula:

Selling price = total estimated cost ÷ (1 − target profit margin)

For example, using a $100,000 estimated cost and a 15% target margin:

$100,000 ÷ (1 − 0.15) = $117,647

The selling price would be approximately $117,647.

That’s different from adding a 15% markup, which would only get you to $115,000 and a lower actual margin. 

Your target margin should reflect the job size, complexity, risk, market, your schedule, and how badly you want the work. Don’t use the same percentage for every project.

Step 10: Review the bid before submitting it

A final review can save you from the mistakes that are hardest to fix after you land a job.

Check that:

• You used the correct drawings and addenda.
• The scope matches the bid form.
• Major quantities were double-checked.
• Labor hours were extended correctly.
• Wage and burden rates are current.
• Supplier and subcontractor quotes are valid.
• Freight and taxes are included.
• Allowances are clearly identified.
• Alternates are separated from the base bid.
• Permits and bonds are included where required.
• Schedule and access restrictions were considered.
• Overhead and profit were applied.
• Assumptions and exclusions are attached.
• The bid expiration date is listed.
• An owner or senior estimator approved the final price.

On larger bids, verify feeder lengths, panel counts, fixture quantities, addenda, exclusions, and vendor quote expirations instead of just checking the final total.

When exclusions, alternates, and document dates are missing from the proposal, you’re more likely to run into bid disputes. Use a commercial electrical bid template to keep those details attached to the price.

Common commercial electrical estimating mistakes

Even experienced contractors can lose money when estimates are rushed or built on incomplete information.

• Missing small material: Boxes, fittings, supports, labels, fasteners, connectors, and consumables can add up fast. Use standard assemblies or checklists to catch commonly missed items.
• Ignoring supervision and project management: Include time for meetings, scheduling, submittals, inspections, documentation, and closeout, even when that work doesn’t happen in the field.
• Missing specification requirements: Review both the drawings and specifications so you don’t miss product, testing, mounting, warranty, or documentation requirements.
• Assuming perfect productivity: Adjust labor units for high ceilings, occupied spaces, congestion, limited access, off-hours work, or an accelerated schedule.
• Skipping the post-job review: Compare estimated labor, material, overhead, and profit with actual results so your next bid is more accurate.

How to protect profit after winning the job

Winning the bid is only the beginning. Use these strategies to keep the estimated profit from disappearing during the project.

• Build labor budgets by phase: Give the field team target hours for rough-in, feeders, trim, fixtures, testing, and closeout.
• Track actual hours weekly: Don’t wait until the job is complete to discover that labor is over budget.
• Update the forecast: Recalculate the expected final cost when productivity, material, or schedule conditions change.
• Track pending changes separately: Keep unapproved extra work visible in the job forecast.
• Lock in major purchases: Confirm price and availability when equipment lead times or changing material prices create risk.
• Bill for stored material: Use stored-material billing when the contract allows it and the required documentation is available.
• Use cost codes consistently: Detailed electrical job costing shows which parts of the estimate were accurate and which need improvement.

How to present a commercial electrical bid

A professional proposal should make it easy for the customer to understand what they’re buying.

Include:

• Contractor and customer information
• Project name and location
• Drawing and specification dates
• Base scope of work
• Base bid
• Alternates
• Unit prices
• Allowances
• Assumptions
• Exclusions
• Proposed schedule
• Payment terms
• Bid expiration date
• Warranty information
• Signature and acceptance fields

Use confident, specific pricing language.

Weak: “This price is higher because commercial work takes more time.”

Strong: “This proposal includes the labor, supervision, equipment, permit costs, testing, and restricted-access requirements identified in the project documents.”

Don’t apologize for a price built from real project costs. Show the customer exactly what’s included and which risks or requirements affect the amount.

How to quote commercial electrical work consistently

When estimates, approvals, invoices, and job records live in separate systems, it’s easier to lose track of scope details and approved pricing.

Housecall Pro’s electrical contractor software keeps estimates, approvals, job details, invoices, and payments connected in one place, so pricing stays consistent and nothing gets lost between systems. Its electrical estimating tools help you:

• Build and send professional estimates from the office or field.
• Save labor rates, material costs, service charges, and commonly used line items so pricing stays consistent job to job.
• Send estimates electronically and keep the customer’s approval attached to the job record.
• Keep approved scope changes with the original job record instead of scattered across email or paper
• Compare estimated labor and material costs against actual job results
• Carry approved work straight into the invoice and track payment in the same workflow
