Electrical contracting
Residential and light-commercial electrical work: the permit-first operating sequence, how service calls and quoted jobs are run differently, the licences and permits that make the work legal, the software the trade runs on, and the numbers that decide whether it is profitable.
For an owner-operator or a crew of two to twenty doing service, renovation and light-commercial installation. Canada-first: the Canadian Electrical Code is adopted provincially, the contractor licence is provincial, and the permit is per job. The US equivalents — the National Electrical Code and state licensing — are named where they differ. This is the business manual, not a code book: it does not tell you how to size a conductor, and no part of it overrides the code or the inspector.
What the website for this business can look like — a Part Owner template, built around the manual below.
Standard operating procedures
The procedures that make the business run the same way twice — each with the hat that owns it, the system it is done in, and the control that catches the mistake. Hand these to staff; they are written to be followed, not admired.
- Capture the address, the contact, the symptom and the age and type of the service — panel brand, amperage, whether there is knob-and-tube or aluminium wiring. Those three facts change the price and the risk more than anything else the customer will say.
- Separate the emergency (burning smell, sparking, no power, exposed conductor, water on electrical equipment) from the service call and the quoted job. Tell an emergency caller to shut off the affected circuit at the panel if it is safe to reach.
- State the diagnostic or minimum call-out charge before booking, in writing.
- Flag anything that will need a permit at intake, not at the door. A job that needs a permit has a different timeline, and discovering that on site costs you the day.
- Ask whether the property is insured, tenanted, or being sold — each changes who must be told what, and sale-related work has a deadline you need to know about now.
- The minimum charge is disclosed before the visit, every time.
- Permit-likely jobs are tagged at intake and reviewed by whoever holds the licence before being scheduled.
- Determine permit requirement from the authority's own current rules, not from habit. In Ontario a licensed electrical contractor files a notification with the Electrical Safety Authority for work that requires it; in British Columbia the permit comes through Technical Safety BC or the local authority with jurisdiction.
- Take out the permit in the contractor's name before starting. Only a licensed contractor may do so, and the licence number on the permit is what links the work to you for its whole life.
- Record the permit number against the job in the system, with the scope as declared.
- Book the inspection at the stage the authority requires — rough-in before closing walls is the one that is expensive to get wrong, because the remedy is to open them again.
- Attach the inspection result to the job record. A passed inspection is an asset: it is what you produce when the work is questioned.
- Where a defect notice is issued, correct and re-inspect before invoicing the final amount.
- No wall is closed before a rough-in inspection where one is required. This is a stop-work control, not a preference.
- Every permit is closed out. An open permit on an address is a defect that surfaces at the worst possible time — during the owner's sale.
- Attend the site. Electrical quoting from a description is how contractors lose money: the price is decided by access, the existing wiring method and the panel's spare capacity, none of which are visible in a photograph.
- Open the panel, photograph it, and record make, amperage, breaker type and spare ways. Some panel brands are effectively unobtainable or known-defective, and that changes the scope entirely.
- Write the scope in terms of what will exist when you leave — circuits added, devices installed, panel work — and list exclusions explicitly: drywall repair, painting, fixture supply, asbestos or knob-and-tube remediation.
- Price the permit and the inspection time as line items rather than absorbing them.
- State the assumption that the quote depends on: 'price assumes existing wiring is copper and accessible from the basement' is the sentence that saves the job when it is not.
- Give the quote a validity period and a payment schedule — deposit, progress, completion on passed inspection.
- No quote above a set value leaves without a site attendance recorded.
- Exclusions are written, not implied. Verbal exclusions do not survive a dispute.
- De-energise, lock out and tag out, then test to confirm dead with an instrument proved before and after use. Working live is permitted only in the narrow circumstances the regulation allows, with the required procedure and equipment.
- Apply the arc-flash and shock protection the task calls for; the assessment is done before the work, not after an incident.
- Verify polarity, bonding and grounding on everything you touch, including what you did not install — you now own what you leave energised.
- Photograph behind the wall before closing it, and attach the photographs to the address record.
- Leave the panel directory legible and correct. It costs five minutes and is the most visible evidence of a professional job.
- Record the test results on the job, not on a loose sheet.
- Proved dead with a tested instrument before any work on a conductor — recorded, and audited by the supervisor on spot checks.
- A job with no behind-the-wall photographs does not pass internal close-out.
- Invoice service work the same day, from the technician's notes, with payment taken at the door for residential.
- Hold the final invoice on quoted work until the inspection passes, and say so in the quote — it aligns your interest with the customer's.
- Attach the permit number, the inspection result and the photographs to the invoice.
- Close the job with actual hours and actual material, then compare against the estimate. Electrical jobs fail on hours, not on material.
- Retain the job record — permit, inspection, photographs, test results — for the long term and indexed by address. This record is also the asset a buyer pays for if you ever sell the business.
- Estimated versus actual hours is reviewed weekly on every job over a set size, and the price book is corrected rather than argued with.
- Lien deadlines are diarised on commercial work at the point of first invoice, because they are short and jurisdictional.
- Verify each electrician's certificate of qualification on the authority's register before the first shift, and record the expiry.
- Keep the contractor licence, its insurance condition and its renewal date in one place with a reminder — operating on a lapsed contractor licence voids permits and, usually, cover.
- Maintain the apprentice-to-journeyperson ratio the province requires, and log apprentice hours as they occur.
- Keep site tickets current: fall protection, aerial work platform, first aid, and arc-flash training.
- Run a monthly ten-minute review of the matrix — expiries, ratios, and who is due for school.
- Nobody is dispatched to licensed work without a verified in-date certificate.
- The contractor licence renewal has a named owner and a calendar reminder ninety days out.

Getting out Not assessed — screened before diligence
The electrical trade's software problem is document retention more than scheduling: permits, inspection results, as-built notes and photographs behind closed walls are what you will be asked for years later, by a lawyer or a buyer's inspector. Choose the field system that attaches photographs and documents to an address permanently, and resist keeping the permit record in a filing cabinet — the job record and the compliance record should be the same record.
Equipment
The kit the system assumes.
| Item | Use | |
|---|---|---|
| Proving unit and two-pole voltage tester | Proving the instrument before and after testing for dead. The proving unit is what makes the test defensible. | 3 |
| Lockout devices, padlocks and tags | Isolation that cannot be undone by someone who does not know you are in the panel. | 3 |
| Arc-rated PPE appropriate to the task | Selected from the task's assessment; stored clean and inspected, because contaminated arc-rated clothing is not arc-rated. | 3 |
| Insulation resistance tester and loop/RCD tester | Verification and fault-finding, and the numbers that go on the job record. | 1 |
| Thermal camera entry-level is sufficient for loose-connection work | Finds loose terminations and overloaded circuits in minutes, and produces an image a commercial customer can understand — which sells the remedial work. | 1 |

Where to get it
The makers and distributors, how to open an account, and how to find the wholesalers in your own city — then the same question answered for whichever country you are in.
| Supplier | What | How to buy | |
|---|---|---|---|
| Electrical wholesale distributors (national and regional) | Wire, devices, panels, fixtures and the counter advice that comes with a trade account. The channel is distributor-led: most manufacturers do not sell direct to contractors. | Open accounts with two distributors and get a project price for anything large — list price is a starting point, not the price. | 5 |
| Manufacturer agents and reps | Specification support, project pricing and lead times on switchgear and lighting. | Through the distributor, or directly for a named project. Worth cultivating: on a long-lead panel, the rep decides whether you make the date. | 5 |
| Certification bodies and the code itself | The Canadian Electrical Code and the certification marks on the equipment you install — both are what the inspector checks. | Buy the current code book per van, and verify that imported equipment carries a mark from a body accredited for Canada. | 6 |
Canada
Equipment must be certified by a body accredited by the Standards Council of Canada and bear that mark; a US-only listing will be refused at inspection. Buy through electrical wholesale distribution, and check the mark on anything imported before it is installed.6
United States
Equipment is listed by an OSHA-recognised testing laboratory. Distribution is deep and online trade pricing is normal; state licensing governs who may install.7
United Kingdom and European Union
UKCA or CE marking as the market requires, and a distributor established in your market so the conformity paperwork sits with them. Importing directly from outside the market usually makes you the importer, with the manufacturer's duties attached.8
Australia
In-scope electrical equipment is registered under the Electrical Equipment Safety System and carries the Regulatory Compliance Mark. Installation work is licensed state by state.9
Wholesale codes: 423610 · 416110. The wholesale codes beside this manual give you the count of electrical wholesalers in your region. In a thin market, stock policy matters more than price: the job you cannot finish because the panel is three weeks out costs more than the discount you negotiated. Find your city on Research Upon’s local research to see who is already operating there, or read what your country requires before a product may be sold to you at all.
Licences and insurance
What it takes to operate legally and be hired by a commercial client.
Licences and registrations
- Electrical contractor licence — The provincial electrical safety authority — the Electrical Safety Authority and ECRA in Ontario, Technical Safety BC in British Columbia, and equivalents elsewhereA company-level licence, separate from an individual's certificate of qualification, and the thing that lets you take out permits and advertise electrical work. Usually conditional on insurance and on a designated master electrician.2
- Certificate of qualification — Construction Electrician — Provincial apprenticeship authority; Red Seal endorsement for interprovincial mobilityCompulsory certification in most provinces for this trade: the work may not be done by an uncertified person except as a registered apprentice under supervision.10
- Permits and notifications per job — The electrical safety authority or the local authority having jurisdictionTaken out before the work by the licensed contractor, inspected at the stages required, and closed out on completion. An uninspected, unclosed permit is a liability attached to the property.2
- Master electrician designation — Provincial authorityRequired in several jurisdictions as the technical head a contractor licence is issued against. If your licence depends on one person's designation, that is a continuity risk worth planning for.2
- Municipal business licence — The municipalitySeparate from the trade licence, needed in each municipality you work in, and routinely checked by commercial clients and property managers.4
Insurance
- Commercial general liability with completed-operations cover, commonly $2M–$5M — Usually a condition of the contractor licence itself, and always a condition of working for a property manager or general contractor. Completed-operations matters because electrical loss — fire — typically occurs long after you have left.4
- Workers' compensation coverage and clearance letters — Mandatory for employees, and the clearance letter is what a general contractor demands before letting your crew on site.11
- Commercial auto with tools and stock cover — Business use is excluded by personal policies, and a van of wire and instruments is worth more than most owners insure it for.4
- Errors and omissions where you design or specify — If you produce layouts, load calculations or specifications, that is professional exposure that a general liability policy does not answer for.4
The numbers to run it on
Few, and the same ones every week. A business this size does not fail from not knowing its market share; it fails from not knowing its collection period.
| Measure | Where it should sit | Why it is this one | |
|---|---|---|---|
| Estimated versus actual hours, per job | Within 10% on quoted work | Electrical jobs are lost on labour, not material. If you measure one number in this trade, measure this one. | 1 |
| Permit close-out rate | 100%, with the open-permit count reviewed monthly | An open permit is an unfinished obligation attached to someone's house. It surfaces during a sale, when it is most expensive to fix and most damaging to say. | 2 |
| Inspection pass rate first time | Above 90%; investigate every failure | A failed inspection is a return visit, a delayed invoice and a signal about either the work or the paperwork. Both are fixable once you know which it was. | 2 |
| Billable hour ratio | 60–70% of paid hours invoiced | Captures the drive time, the parts runs and the re-work that a daily schedule hides. | 1 |
| Average days to collect, by customer type | Residential at zero; general contractors tracked individually | On commercial work the risk is not whether you are paid but when, and a general contractor's payment behaviour is the single most useful thing to know about them. Lien deadlines are the backstop, and they are short. | 1 |
| Service-call conversion to quoted work | Measured; a panel inspection on every call is the mechanism | The profitable work in residential electrical is found during the small job. A technician who looks at the panel and reports what they see converts routine calls into upgrades without selling anything. | 1 |
Not yet established
What the sources did not settle. Nothing here is guessed at elsewhere on the page.
- Which classes of work require a permit, and at which stages inspection is mandatory, differ by jurisdiction and are not reproduced here — the authority's current rules govern.
- Whether the electrician trade is compulsory-certification, and the apprentice supervision ratio, were not established province by province.
- Live-work rules — when it is permitted at all, and what procedure and equipment are required — are summarised only in principle; the provincial occupational health and safety regulation is the operative text.
- Construction lien periods are jurisdictional and short; no period is quoted here deliberately. Take local advice at the first invoice on any commercial job.
