Electrical Change Order Pricing Examples That Protect the Margin
Electrical change order pricing examples show AIA-style fixed-price and T&M markups that protect margin on commercial electrical work in the US.
What to take away
- Change orders leak margin when scope, markup, and labor rate are not fixed before the extra work starts.
- Fixed-price extras often protect margin better than open-ended time-and-materials when the added work is clear.
- A written change order with a markup range of 15 to 25 percent on labor and material gives both sides a defensible number.
- Check actual hours against the approved estimate within one day of finishing the extra work.
- If the change affects panel capacity, feeder sizing, or life safety, stop and send it to a licensed engineer.
What has to be true before the first step
The original contract must allow change orders. Confirm that the owner or general contractor signed a base contract with a change order clause. Confirm the base labor rate, material markup, and overhead recovery method are already agreed. Without those, negotiation happens after the work, which is where margin leaks.
Under FAR Part 43, a change order is a written modification. That discipline transfers to private jobs. Confirm added scope is measurable: not "add more receptacles" but "add four 20-amp duplex receptacles on the west wall, with conduit exposed, within existing panel capacity."
On private commercial work, the standard document is AIA G701, the Change Order form. Residential and small commercial jobs can use a plain written amendment, provided it carries the same detail.
If the original quote did not set these rates, review contractor quote examples before quoting the first extra.
Markup and multiplier ranges that protect margin
Markup and multiplier ranges
| Change type | Pricing method | Common U.S. range |
|---|---|---|
| Small added receptacle or switch | Fixed price | 15 to 25 percent markup |
| Open-ended troubleshooting | Time and materials | 1.4 to 1.65 times base wage |
| Long lead material only | Cost plus | 10 to 20 percent handling markup |
A change order is a pricing decision. If the markup is wrong, clean paperwork still loses money.
Change Order Markup Ranges

Common U.S. range

These ranges are illustrative starting points. Your audited overhead and local market set the final number.
The sequence
- Write the change before work begins. List added materials, labor hours by trade, and any reuse of existing circuits.
- Price the change. Use the markup table above for fixed-price or T&M work, and show the arithmetic on the form.
- Ask the owner or general contractor to sign before any crew pulls wire. A verbal go-ahead does not protect margin.
- Attach a sketch or photo if the work modifies an energized panel. This limits later claims about what was there.
Setting the labor multiplier
The decisive step is fixing the labor multiplier. Set it too low and every change loses money on taxes, insurance, and unbilled time. Set it too high and the owner rejects the extra. The table above gives the range for each change type.
IRS Publication 535 lists deductible overhead costs. Those same line items belong in the multiplier. Overhead includes costs such as an electrical safety program cost review.
Example: Fixed-price change order for added receptacles
A commercial tenant asks for four added duplex receptacles in an office. The existing panel has spare capacity. The quote lists 8 labor hours at the agreed base rate of $85 per hour, or $680, plus $220 for conduit, wire, boxes, and devices.
Combined labor and material cost is $900. A 20 percent markup adds $180, so the signed price is $1,080.
The owner signs before work starts. The crew finishes in 7.5 hours, so the real labor cost is $638. Total cost is $858 and gross margin lands near 21 percent of the price.
Replace the $85 rate and the $220 material figure with your own numbers. The margin holds because the markup covered the half-hour of layout that no one estimated.
How to check each step came out right
- Compare the signed scope with the work ticket. Receptacle counts, circuit feet, and fixture counts must match.
- Check labor hours against the estimate within one day of completion. A four-hour variance signals a bad multiplier.
- Verify material invoices match the change order line items before billing.
- Record the final margin on the change order. If the average drops below target, adjust the next markup.
When actual hours run over the estimate
If actual hours run 20 percent over the approved change order, stop and reprice the remaining work before completing it. How the overage is handled shapes later referrals, and a system for turns customers into referrals helps. Do not absorb the overage by cutting material quality or skipping a lockout/tagout step. Issue a revised change order for the added hours and ask for approval.
The common failure is assuming a small overage will average out later. It rarely does. If the owner refuses the revised change, document the refusal and decide whether to stop work.
When to stop and hand it to a professional
Stop and send the change to a licensed electrical engineer when the work changes panel capacity, feeder sizing, fault current, or ground fault protection. A change that moves a receptacle is not that. A change that adds a subpanel often is.
The handoff condition is not the dollar size. It is whether the change requires a load calculation or a stamped drawing. If the owner asks you to sign off on a design change outside your license, decline and route it to the engineer of record.
If the owner disputes the changed scope, a complaint routine keeps that dispute separate from the design question.
Retainage, bonding, and subcontracted change work
Retainage follows the change order. If the prime contract withholds 10 percent until substantial completion, your change order price is cut by the same 10 percent. Price the extra work as money that arrives months later.
A change that lifts the contract value above a bonding threshold may need a rider. Tell the surety agent before you sign.
Subcontracted change work needs a second markup layer. You carry the schedule, the coordination, and the warranty. A typical U.S. range is 10 to 20 percent on top of the subcontractor's price.
Pass the same terms down: signed scope, fixed price, and the same retainage. If the sub bills time and materials while you sold a fixed price, the difference comes out of your margin.
