Selling, letting or insuring a property in Johannesburg CBD? The electrical COC is one of the documents that holds up transfers most often. We get it done properly and quickly, and we tell you the cost of any remedial work before we start it.
Known for the inner city — high-rise commercial and residential blocks, converted industrial buildings and dense mixed-use precincts, much of it on ageing distribution infrastructure, Johannesburg CBD keeps our teams busy across every kind of installation from single plug points to three-phase distribution.
Because Johannesburg CBD falls under City of Johannesburg and is supplied by City Power, anything that touches the connection itself follows their process and their timelines. We work to those rather than promising you turnaround times that are not ours to give.
Electrical COC Certificate services we provide in Johannesburg CBD
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 Johannesburg CBD
Extended homes and added circuits
Homes in Johannesburg CBD have typically grown over time — rooms added, outbuildings converted, backrooms let out. Each addition tends to be spurred off whatever circuit was closest, so the original board ends up carrying loads it was never designed for. The repair is usually less about the last thing that failed and more about redistributing the installation sensibly.
Decades of small alterations
Very few older properties in Johannesburg CBD still match their original circuit layout. Extensions, converted garages, replaced geysers and DIY additions accumulate, and each one leaves the installation slightly further from what anyone documented. We spend as much time working out what was done as we do fixing what failed — which is why a proper circuit schedule is part of our handover.
Apartment blocks and shared supply
Multi-unit buildings in Johannesburg CBD bring their own problems: shared risers, common-property boards, sub-metering disputes and faults in one unit that trip another. Work in these buildings needs coordination with the managing agent or body corporate, and clear documentation of where the fault actually was.
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 Johannesburg CBD 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 Johannesburg CBD — 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 Johannesburg CBD?
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.
