Quick answer: Build an electrical quote from a defined scope, loaded labor hours, materials, permits, travel and overhead. State exclusions and obtain a separate approved change order when the work expands.
An instruction such as 'install a new outlet' can hide decisions about circuit capacity, access, wall repair, testing and permit requirements. Customers may compare two prices without realizing they cover different work. A useful estimate names the specific task and the conditions under which the price may change.
How to approach the job
- Identify the location, device or circuit, access conditions, shutdown needs and who supplies materials.
- Estimate installation, testing, cleanup and documentation hours separately.
- Include materials, any required permit or inspection allowances, travel and overhead.
- List exclusions such as concealed wiring damage, additional circuits, drywall restoration and panel replacement unless expressly included.
- Document added work with a written change order covering price and schedule before proceeding.
Worked example: hypothetical costs
These are invented numbers to illustrate the method. Replace every input with your actual costs, work scope and local requirements before quoting a customer.
| Illustrative cost or comparison item | Amount |
|---|---|
| Labor: 3 hours at $85 loaded cost | $255.00 |
| Materials | $135.00 |
| Illustrative permit/inspection allowance | $40.00 |
| Travel/setup | $30.00 |
| Overhead allocation | $65.00 |
The example cost basis is $525. A 30% target gross margin means $525 ÷ 0.70 = $750. If a discovered additional circuit requires $90 materials, $85 labor and $25 overhead, that $200 added cost would need a $285.71 separately approved change-order price at the same target margin.
Important limits and assumptions
These are invented numbers for demonstrating the arithmetic, not recommended local electrical rates. Use actual loaded wages, insurance, materials and code-related costs. A pricing spreadsheet cannot establish that a job is safe, compliant or suitable for an unlicensed person. If the scope changes for safety or compliance, stop and reassess rather than quietly continuing.
Make the estimate clear to the customer
A strong change order references the original quote, explains the new condition, states the added price, identifies any schedule impact and records customer authorization. Compare planned versus actual hours after completion so the next estimate is more accurate.
Frequently asked questions
Is a 30% margin the same as a 30% markup?
No. Divide costs by 0.70 for a 30% gross margin. Multiplying costs by 1.30 produces a smaller margin.
What if the customer verbally requests extra work?
Record the scope and price and obtain the approval required by your agreement and applicable local rules.
Use your own figures
Educational illustration only. Verify local taxes, licenses, permits, safety, actual costs and contract terms for each job.
Before you send an electrical change order
Identify the original approved scope, the newly discovered condition, the materials and labor being added, and any schedule impact. Record the customer's approval of the revised scope and price before proceeding when required. An illustrative labor estimate is not a substitute for applicable safety, permit, or code requirements.
