Quick Answer
What actually drives the price of an electrical inspection:
- Home size and age, the scope of the assessment, and any add-ons like thermal imaging or grounding tests.
- A contractor's inspection fee is separate from ESA fees — ESA's minimum residential notification fee is $88, and only applies to permitted work.
- The cheapest quote often means a thin report, which can cost you more later.
"What does an electrical inspection cost?" is a fair question, but it's a little like asking what a car costs — the honest answer is "it depends on what you're getting." Rather than quote you a number that won't fit your home, let's walk through the things that actually move the price, so you can read any quote you receive and know whether it's fair. As a Toronto electrician, I'd rather you understand the cost than chase the lowest one.
The Main Cost Drivers
A few factors determine how much time and expertise an inspection takes, and time is what you're paying for:
- Home size. A one-bedroom condo has one panel and a handful of circuits. A three-storey detached home has far more to examine, and every additional area adds time.
- Home age. Older Toronto homes often have mixed wiring vintages, less accessible junction boxes, and more history to document. Century homes take longer than newer builds.
- Scope. Are you after a focused check of one concern — say, a suspect panel — or a full-house condition assessment for insurance or a purchase? Broader scope means more cost.
- Thermal imaging add-on. An infrared scan of panels and connections to catch hot spots. It needs specialized equipment and interpretation, so it typically adds to the fee.
- Grounding and resistance tests. Measuring the effectiveness of the grounding system is a specialized test beyond a visual check, and adds cost where it's warranted.
- Report and documentation needs. A detailed written report an insurer or lawyer can rely on takes more effort to produce than a quick verbal summary — and it's usually the whole point.
Contractor Assessment vs ESA Fees
This is the single biggest source of confusion around inspection cost, so it's worth being precise. There are two very different kinds of "fee" people lump together:
- A contractor's inspection fee. This is what you pay a Licensed Electrical Contractor to assess your system and write a report. It's a service fee, and it's what most of this article is about. A Portman electrical safety inspection falls in this category — a non-destructive assessment of visible components with a written report.
- ESA fees. These are government charges tied to permitted electrical work. When work requires a permit, a Notification of Work is filed with ESA, and ESA inspects the work. ESA's minimum residential notification fee is $88, and the actual amount scales with the scope of the job.
The key point: a condition assessment on its own doesn't involve an ESA fee, because no permitted work is happening. ESA fees only enter the picture when the inspection leads to repairs — a rewire, a panel upgrade, new circuits — and that work has to be permitted and inspected. If the difference between a contractor's report and an ESA record still isn't clear, our guide on the electrician's letter vs ESA Certificate of Acceptance spells it out.
Remember, too, that a Portman assessment is not an ESA inspection. ESA reviews permitted work under provincial authority and issues the Certificate of Acceptance; our assessment is a contractor's professional opinion of what's visible and accessible. Both have their place — they're just priced and scoped differently.
Why the Cheapest Isn't the Best
It's tempting to book whoever quotes the lowest number, especially when you're staring at an insurance deadline. But a rock-bottom inspection usually buys you a rock-bottom report: a quick walkthrough, a couple of lines, and no clear statement of what was actually verified. When your insurer, your lawyer, or a buyer comes back with a follow-up question the report can't answer, you're paying again — and possibly against a tighter deadline.
A proper assessment costs a bit more because it takes real time and produces something you can lean on. It should be done by a Licensed Electrical Contractor who can not only identify problems but remediate them — so you're not restarting with a new company if repairs turn up. Value, not just price, is what protects you here.
What a Proper Report Includes
When you pay for an inspection, the report is the deliverable. A good one should cover:
- Service and panel details. The service size (60, 100, 200 amp), panel type, and its overall condition.
- Wiring types found. Whether knob-and-tube, aluminum, or modern copper wiring is present where it's visible.
- Grounding and bonding. The condition and adequacy of the grounding and bonding system.
- Clear limits. An honest statement that concealed wiring behind finished walls couldn't be verified — non-destructive assessments can't see everything.
- Prioritized findings. A plain-language list of issues and recommendations, ranked by urgency, that a non-electrician can understand.
- Contractor credentials. Signed by an ECRA/ESA Licensed Electrical Contractor so an insurer or lawyer can rely on it.
Budgeting for Repairs, Not Just the Inspection
If your inspection is driven by an insurance letter or an older home, plan for the possibility of repairs on top of the assessment. The two most common remediation jobs we see are knob-and-tube rewiring and panel and service upgrades. Those are separate projects with their own costs and — where required — their own ESA fees. For a sense of what a panel upgrade involves, see our breakdown of panel upgrade cost in Toronto. And if you're gathering paperwork for a policy, our guide to an electrical inspection for insurance in Ontario covers the whole process.
We don't publish a fixed price list here because an honest quote depends on your specific home and what you need. The best step is a quick conversation about your property so we can scope it properly and tell you what the assessment — and any likely repairs — will actually involve.

Common Questions About Inspection Cost
How much does an electrical inspection cost in Toronto?
There's no single number, because it depends on the size and age of the home, the scope of the assessment, and whether add-ons like thermal imaging or grounding tests are included. A small condo assessment is very different from a full-house inspection of a century home. Ask for a scope-based quote rather than a flat 'inspection fee.'
Is a contractor's inspection the same cost as an ESA fee?
No — they're separate things. A contractor's inspection is the fee for a Licensed Electrical Contractor to assess your system and write a report. An ESA fee is a government charge for a Notification of Work (permit) and inspection of permitted work. ESA's minimum residential notification fee is $88; the actual amount scales with the scope of the work.
Do I always have to pay an ESA fee too?
Only if permitted electrical work is being done. A condition assessment on its own doesn't involve an ESA permit. But if the inspection leads to repairs — a rewire, a panel upgrade, new circuits — that work requires an ESA Notification of Work and inspection, which carries its own fee.
Why do bigger and older homes cost more to inspect?
More square footage means more panels, circuits, outlets, and runs to examine. Older homes add complexity — mixed wiring vintages, less accessible junction boxes, and more to document. A thorough assessment of a large century home simply takes more time than a small newer one.
What is thermal imaging and does it cost extra?
Thermal imaging uses an infrared camera to spot hot spots at connections and in panels that can indicate loose or overloaded terminations. It's a valuable add-on that usually adds to the cost because it requires specialized equipment and expertise. It's optional but often worthwhile on older or heavily loaded systems.
Why isn't the cheapest inspection the best choice?
A very cheap inspection is often a quick look with a thin report. If an insurer, lawyer, or buyer later asks a question the report doesn't answer, you may have to pay again. A proper assessment with a detailed written report — clearly stating what was and wasn't verified — is more useful and usually saves money overall.
What should a proper inspection report include?
The service size and panel type, the wiring types found where visible, grounding and bonding condition, a note of anything that couldn't be verified without opening walls, and a prioritized list of findings and recommendations in plain language. It should be signed by a Licensed Electrical Contractor.
Does the inspection cost go toward repairs?
That's between you and your contractor and depends on how they quote. Some roll the assessment into a larger repair project. Ask up front how the inspection fee relates to any repair estimate so there are no surprises.
Is a contractor inspection the same as an ESA inspection?
No. A contractor inspection is a non-destructive assessment of visible components with a written report — the contractor's professional opinion. An ESA inspection reviews specific permitted work under provincial authority and ends in a Certificate of Acceptance issued by ESA. They're distinct and priced differently.
