Aluminum Wiring Inspections & ESA Certificate of Acceptance Support
If your home contains aluminum wiring, your insurance provider may require an inspection and any necessary electrical repairs before issuing or renewing your policy. At Thomson Electric, we provide professional aluminum wiring inspections, approved repairs, and coordinate the required electrical work so it can be reviewed by the Electrical Safety Authority (ESA).
When electrical work is completed and accepted through the ESA notification and review process, an ESA Certificate of Acceptance is issued for the completed work. This document is commonly requested for insurance, home sales, and your permanent records.
Aluminum Wiring Inspection Services

Our inspection includes:
- Aluminum branch circuit assessment
- Electrical panel inspection
- Switch and receptacle inspection
- Connection and termination evaluation
- Grounding and bonding review
- Electrical safety assessment
- Code compliance recommendations
Following the inspection, we explain our findings and recommend the most appropriate solution for your home.

ESA Notification & Certificate of Acceptance
As a licensed electrical contractor, Thomson Electric files the required ESA notification for eligible electrical work and arranges the review process where required.
Once the completed work has been reviewed and accepted, the person who filed the notification receives an ESA Certificate of Acceptance, confirming that the completed electrical work complies with the Ontario Electrical Safety Code. This certificate is often requested by insurance companies and can also be valuable when selling your home.

Frequently Asked Questions
Does aluminum wiring automatically need to be replaced?
No. Aluminum wiring is permitted under the Ontario Electrical Safety Code when properly installed and maintained. Whether repairs or replacement are appropriate depends on the condition of the wiring and connections.
Can you help with insurance requirements?
Yes. Many insurers require an inspection and, in some cases, repairs before providing or renewing coverage. We can assess your electrical system, complete recommended work, and assist with the ESA notification process when applicable. Insurance requirements vary by provider.
What is an ESA Certificate of Acceptance?
An ESA Certificate of Acceptance confirms that the completed electrical work covered by the notification has been reviewed and accepted as meeting the Ontario Electrical Safety Code.
How do I know if my home has aluminum wiring?
Homes built between the mid-1960s and late 1970s are more likely to contain aluminum branch-circuit wiring. Thomson Electric can inspect your home and confirm the type and condition of your wiring.
