A Certificate of Compliance is not a formality — it is a statement, by a registered person, that your installation meets SANS 10142-1. That is why it cannot simply be bought, and why a cheap certificate issued without a proper inspection is worth nothing to you or your insurer.
Randburg is defined by a broad, mostly residential belt of 1960s–80s freestanding homes now mixed with townhouse complexes and busy neighbourhood retail strips, and the electrical work follows from that.
Electricity in Randburg is distributed by City Power. Your responsibility as the owner starts at the point of supply and covers everything inside it — the board, the circuits, the earthing and the fittings. That is the part we look after, and the part a Certificate of Compliance speaks to.
Electrical COC Certificate services we provide in Randburg
Full installation inspection
A physical inspection of the DB board, earthing, bonding, circuits, points and fittings throughout the property.
Testing with calibrated instruments
Earth continuity, insulation resistance, polarity, earth fault loop impedance and earth leakage trip testing — recorded, not estimated.
Written report of defects
A plain list of what fails and why, with each item priced so you can decide what to fix and what to question.
Remedial repairs
We carry out the corrective work ourselves, so you are not chasing a second contractor against a transfer deadline.
Certificate issued by a registered person
A valid COC with the test results attached, issued only once the installation actually complies.
Supplementary COCs
Certification for alterations — new circuits, solar, inverters, cottages or board changes — added to an existing installation.
Landlord & rental certificates
Documentation for lease files and managing agents, with a copy kept on record.
Solar & inverter certification
Certification of embedded generation installations, including the documentation needed for SSEG registration.
What we see in Randburg
Installations that have outlived their design
The wiring in much of Randburg was designed for a household that had a stove, a geyser and a television. It is now running heat pumps, pool equipment, home offices, backup systems and a dozen always-on devices. Nothing has failed exactly — it has simply been asked to do a job it was never specified for, and the distribution board is usually where that shows first.
Shared infrastructure and access rules
A great deal of work in Randburg happens behind a boom gate. That means clearance with estate security, insurance and worker details submitted in advance, and often a scheme rule about when noisy or disruptive work may happen. We handle that paperwork as a matter of routine rather than discovering it at the gate on the morning of the job.
Compliance that someone will eventually ask for
Landlords, insurers and lease renewals in Randburg all eventually ask the same question: where is the current Certificate of Compliance, and does it cover the work the tenant did? Getting that documented while the premises are trading normally is considerably cheaper than assembling it under pressure after an incident.
How long a COC is actually valid
This is the single most misunderstood rule in South African electrical work, and plenty of contractors get it wrong — sometimes conveniently.
It does not expire every two years
A Certificate of Compliance stays valid for the life of the installation, as long as nothing has been altered or added since it was issued. Nobody has to renew a certificate simply because two years have passed while they carry on living in the house.
The two-year rule is about transfer
When a property changes hands, the certificate presented may not be older than two years. That is where the two-year figure comes from — and it is why most sellers in Randburg need a fresh inspection even though their installation has not changed.
Alterations need a supplementary certificate
Add a circuit, a cottage, a DB board, solar or an inverter and that work needs its own certificate. Your original COC does not stretch to cover it.
A certificate without an inspection is worthless
Only a registered person may issue a COC, and only after inspecting and testing the installation. If anyone offers you one over the phone, they are selling paper that will not stand up to an insurer.

Electrical COC Certificate in Randburg — your questions answered
How long is an electrical COC valid in South Africa?
This is the most misunderstood rule in the industry. A COC remains valid for the life of the installation provided nothing has been altered or added. The two-year rule applies to property transfer: for a sale, the certificate may not be older than two years. It is not a certificate that expires and needs renewing every two years while you live in the house.
What happens if my installation fails the inspection?
You get a written list of the defects with a price against each one. Nothing is repaired without your go-ahead, and the certificate is only issued once the installation genuinely complies. We would rather lose a job than issue a certificate that is not true.
How quickly can you do a COC inspection in Randburg?
Usually within a few working days, and sooner when a transfer date is under pressure. Call 084 412 1814 with your date and we will work to it.
Can I get a COC without an inspection?
No. Only a registered person may issue a Certificate of Compliance, and only after inspecting and testing the installation. Anyone offering a certificate over the phone or without attending the property is selling you a document that will not protect you.
Who pays for the COC when a property is sold?
By convention it is the seller, and most sale agreements say so — but check yours, because the wording varies. What is not negotiable is that the certificate has to reflect the true state of the installation.
Do I need a new COC after adding solar?
Yes. Solar is an alteration to the installation, so it requires certification, and you will need that certificate for SSEG registration and for your insurer.
