A Certificate of Compliance records that an electrical installation was inspected, tested and found compliant at the time it was issued.
What a COC actually confirms
An electrical Certificate of Compliance, usually called a COC, is issued after an installation has been inspected and tested by a registered person. It is supported by a test report covering the installation that was checked. It is not simply a receipt for electrical work and it should not be issued without testing.
The inspection is measured against the electrical installation requirements that apply in South Africa, including SANS 10142-1. In practical terms, the electrician checks protection, earthing, bonding, circuit arrangements, conductor condition and test results. Any defects that prevent compliance must be corrected before the certificate can be issued.
Why the certificate matters
A compliant installation reduces the risk of electric shock, fire and damage caused by incorrect wiring. The COC also creates a clear record of responsibility. Owners, buyers, insurers and contractors can see what installation was covered and when it was tested.
A certificate does not guarantee that nothing will ever fail. Appliances wear out, alterations happen and damage can occur after the inspection. It confirms the condition and compliance of the covered installation at the time of testing. Keep the certificate and test report with the property records.
Property sales and changes of ownership
A valid electrical COC is normally required when ownership of a property changes. Sellers often discover problems late because the inspection is left until transfer is already moving. Older DIY work, open joints, missing labels, faulty earth leakage or additions that were never certified can then delay the process.
Arrange the inspection early enough to allow for remedial work. The electrician must report what does not comply and provide a clear scope for correction. A low price for a certificate without a proper site inspection should be treated cautiously. The document only has value when the testing behind it is real.
New work, alterations and additions
New circuits, DB changes, additional plug points, outbuildings, pool equipment, inverter connections and substantial alterations need to be incorporated into compliant electrical documentation. Where an addition or alteration is made to an installation with an existing certificate, the new work must be inspected, tested and certified for the applicable scope.
Keep every supplementary certificate with the original property file. If several contractors have worked on the site over time, those records help the next electrician understand what changed. They also reduce confusion during a later sale, renovation or insurance query.
Repairs after damage
Fire, flooding, roof leaks, cable damage and failed equipment can affect more than the visibly damaged item. Repairs should include testing of the affected circuits and protection. Where the installation has been altered or reconstructed, updated compliance documentation may be required for that work.
Insurance processes often ask for proof that electrical repairs were completed correctly. Photographs, invoices, test results and the relevant COC should describe the actual work. Do not accept a certificate that lists the wrong address, omits the test report or covers a scope that was not inspected.
What happens during a GJS compliance visit
GJS starts with the DB and the visible installation, then carries out the electrical tests required for the property and scope. We note defects, explain the work needed and separate compliance items from optional improvements. That gives the owner a practical route to sign-off without vague repair lists.
For a sale, renovation handover or concern about older wiring, send the property details and any existing certificates before the visit. Compliance requirements can depend on the installation and work completed, so this guide is general information rather than a substitute for a site inspection.
Before accepting a new certificate, check that the property address, installation details and registered person are recorded correctly. The certificate should be accompanied by the relevant test report, and any limitations in the covered scope should be clear. Ask questions while the work is still fresh instead of trying to reconstruct the inspection during a later transfer.
If a previous certificate exists, give it to the electrician rather than assuming it still covers every circuit. Kitchens are remodelled, plugs are added and inverter systems are connected over time. The site condition and documented alterations determine what must be inspected and certified now.
