The ceiling is lined, the quoted cable route is blocked, and another trade wants to close the wall. An electrical contractor change order keeps that discovery from turning into unapproved work.
Stop only the affected work. Leave the area safe, preserve the evidence, and decide what changed before you price it.
Use an electrical contractor change order to control the change
A change order records an agreed change to the accepted scope, price, schedule, or task ownership. It sits beside the original quote. It does not replace it.
Renovation changes can add work, remove work, or move responsibility without changing the price. Record all three. A no-price change can still alter the route, inspection sequence, access, or work assigned to another trade.
Use a separate reference for each change. Link it to the accepted quote, drawings, site notes, approval, cost entries, and final invoice.
Stop the affected work and preserve the site evidence
Make the electrical area safe first. That safety decision does not approve the broader work or make every added task chargeable.
Photograph the room, fixture position, planned route, opened surface, and obstruction. Record who found the condition and when. Do this before the wall or ceiling is closed.
Write what physically changed. “Extra work required” tells you nothing later. State that the homeowner requested another downlight, demolition exposed a blocked route, or the lined ceiling prevented the quoted access method.
Tell the general contractor what has stopped. Keep unrelated work moving where practical. If someone wants the wall closed immediately, ask for written direction and price approval before completing the added scope.
Test the discovery against the accepted scope
Read the quote, drawings, assumptions, and exclusions. Use the documents. Do not rely on somebody’s memory of a conversation beside the panel.
Put the discovery into the right bucket:
- Customer request: The customer asks for another fixture, a different control, or a new location.
- Concealed condition: Opened work reveals a route, access, or electrical condition that could not be seen earlier.
- Design revision: The circuit, fixture, control, route, or installation method changes.
- Coordination change: Another trade changes access, timing, surface preparation, or the available route.
- Included work: The accepted scope already assigns the task to you.
- Estimating omission: Your quote left out work shown in the accepted documents.
- Rework: Your crew must correct defective or incomplete installation.
Harder work is not automatically extra work. If the accepted scope included the route, access, testing, and surface work, the task may remain yours even when it takes longer.
Track an estimating omission against the base job. Track defective work as rework. Do not disguise either as customer-approved electrical scope changes.
Clear assumptions and exclusions make this decision easier. Use the guide to writing a quote to name access, testing, patching, and customer-supplied items before work starts.
Define the work before calculating the price
Write the changed scope in physical terms. Name the room, circuit, fixtures, quantities, cable route, access method, shutdown, testing, inspection, and return visit.
Assign the surrounding renovation tasks. State who handles cutting, patching, painting, debris removal, surface protection, and access. “By others” is weak. Name the task and the responsible party.
Use this blank record:
Change order reference: [reference] Job reference: [job] Original quote or agreement: [reference] Requested or discovered by: [name and role] Trigger and site condition: [plain description] Evidence: [photograph and site-note references] Changed electrical scope: [room, circuit, fixtures, route and testing] Task ownership: [cutting, access, patching, painting and debris] Exclusions: [work not included] Pricing basis: [fixed price, time and materials, or other agreed basis] Approved limit: [amount or not used] Cost and markup basis: [labour, materials, equipment, subcontract and markup details] Change price: [amount] Revised job total: [amount] Schedule effect: [sequence, delay or return visit] Permit effect: [whether the change affects the permit] Permit responsibility: [who will amend the permit] Inspection effect: [changed sequence, hold point or return inspection] Permit and inspection reference: [reference] Federal and provincial tax references: [records] Authorised approver: [name and role] Approval date and method: [record]
Do not price the document while its scope is still vague. Settle the work and task ownership first.
Ask two permit questions at two desks
Ask the provincial or territorial electrical authority whether the changed electrical work affects the electrical permit or inspection path. Ask which electrical permit and inspection tasks belong to your business, then write down the answer.
Find the local building authority responsible for that site. It may be a municipality, regional body, delegated agency, or other authority having jurisdiction. Ask whether the renovation change affects the building permit or building inspection sequence.
Tax is a separate question. Ask the Canada Revenue Agency about GST/HST. Ask the relevant provincial tax authority about any provincial sales tax question. Keep both answers with the job.
Build the price from the defined work
Calculate the labour caused by the change. Include installation, access, supervision, shutdown, testing, inspection attendance, and return travel only when those tasks belong to the changed scope.
Add the required materials at your current cost. Then add equipment, access, and subcontract costs carried by your business. Apply your established markup to the resulting cost.
Added labour cost + Added material cost + Equipment and access cost + Subcontract cost = Added job cost Added job cost + Contractor markup = Change price
Markup is what you add to cost to form the selling price. Margin is profit as a share of the selling price. They are not interchangeable.
Record the agreed pricing basis. If part of the route remains hidden, describe what is unknown, any approved limit, and how labour, materials, equipment, subcontract costs, and markup will be charged.
Do not use an average percentage for a renovation change. A percentage of the original quote cannot price the route, access work, shutdown, testing, materials, or return visit. Use your own figures for the defined tasks.
Get change approval from the person with authority
Your business can prepare the electrical contractor change order. The person who requests the work may not be the person authorised under the accepted agreement to approve its price.
A site superintendent might control sequencing. A designer might issue a revised layout. A homeowner, general contractor, or project manager might control commercial approval. Write down who has authority before the renovation reaches this point.
Record the trigger, changed scope, task ownership, price, schedule effect, exclusions, and approval method. A direction to proceed quickly is not the same record as approval of the added price.
Keep the added work stopped until approval arrives. Leave the site safe and continue unrelated work where practical.
Hand the approved scope to the crew
Give the crew the approved reference. Mark the fixtures, quantities, route, access limits, shutdown, and testing covered by it.
Remove superseded sketches and site notes from the immediate work area. The electrician should not have to choose between an old drawing and a message on somebody’s phone.
Open another change record when a second discovery changes the work again. Approval for extra cable does not automatically cover another fixture, a different circuit, or added patching.
Use cost tracking while the change is live
Enter each electrician’s time against the approved change reference every day. Record material quantities, supplier documents, returned materials, equipment, access costs, and subcontract invoices against the same reference.
Compare actual vs estimated cost before closing the record. This shows whether access, testing, materials, or a return visit cost more than planned without distorting the base quote.
Clean cost tracking protects job profitability. The job-costing guide based on actual contractor records explains how to calculate job cost once the matching labour and material entries are complete.
Do not judge an electrical contractor change order before all of its costs have arrived. A missing supplier invoice can make the change look healthier than it was.
Show the approved change on the revised electrical invoice
Keep the accepted quote unchanged. Add each approved change as a separate invoice line with its reference and description.
Oak Street worked example
These figures are sample currency units. They are not a rate card.
R. Chen’s quote Q-1847 for 14 Oak Street was 1,105. It covered a 150mm bathroom exhaust fan ducted through the roof and four LED downlights. The ceiling was lined, and chasing was excluded.
Extra cable and chasing were approved on site as a 160 change order. Show the revised electrical invoice like this:
Accepted work under Q-1847: 1,105 Approved extra cable and chasing: 160 Invoice INV-1847 total: 1,265
The costs caused by the 160 change are not given. Do not combine the job cost of 850 with the 1,265 invoice or calculate profit from the invoice total.
Yes Foreman can keep each electrical contractor change order, quote, job cost, and invoice attached to the same job. Review the job record features after you have settled the field process your crew will follow.
