What is an Electrical COC?

A Certificate of Compliance (COC) is an official document issued by a registered electrical contractor confirming that an electrical installation meets the requirements of SANS 10142-1 — the South African National Standard for the Wiring of Premises. It is a legal requirement under the Occupational Health and Safety Act and is mandatory for property transfers, insurance claims and solar installations.

Property Transfers — Legal Requirement: Under South African law, a deed of sale cannot be finalised by conveyancing attorneys without a valid COC. Without it, your property transfer cannot proceed — regardless of how far along the process you are.

Property Transfers

A valid COC is a legal prerequisite for the transfer of property ownership in South Africa. No COC — no transfer.

Insurance Claims

Most South African insurers will reject fire or damage claims without a valid COC. It proves your installation was maintained responsibly.

Solar & Inverter Installations

A COC is legally required for all grid-tied and hybrid solar systems. Your existing installation must also be compliant before a solar COC can be issued.

Commercial Leases

Landlords are required to provide a valid COC to tenants. As a property owner you are legally liable for the safety of everyone on the premises.

Industrial Properties

Factories, warehouses and workshops require COC certification covering 3-phase supply, earthing systems and all fixed equipment.

Legal Liability

A COC protects you from litigation in the event of an electrical accident or fire. Without one, liability falls directly on the property owner.

How the COC Process Works

From your first call to certificate in hand — here is exactly what to expect.

Book the Inspection

Call, WhatsApp or submit a quote request. Tell us the property type, size and your area on the East Rand.

Site Inspection

Our registered inspector visits the property and conducts a full SANS 10142-1 evaluation of the installation.

Pass or Remedial Report

If compliant — COC issued immediately. If faults are found — you receive a detailed report and a transparent quote for remedial work.

Remedial Work

We carry out all required repairs and upgrades to bring the installation up to code — no need to find a separate contractor.

COC Issued

Re-inspection completed, certificate issued. Valid for 2 years from date of issue for property transfers.

COC Validity: A COC is valid for 2 years from date of issue, provided no alterations have been made to the installation. If electrical work is carried out after the COC is issued, a new certificate is required for the affected circuits. Always use a registered electrical contractor for any work on your installation.

COC Certificate — Common Questions

What is an electrical COC certificate?
A Certificate of Compliance (COC) is an official document issued by a registered electrical contractor confirming that an electrical installation meets the requirements of SANS 10142-1 — the South African National Standard for the Wiring of Premises. It is a legal requirement under the Occupational Health and Safety Act.
Do I need a COC to sell my house?
Yes. A valid electrical COC is a legal requirement for the transfer of property ownership in South Africa. Conveyancing attorneys cannot finalise the transfer without it. The certificate must be issued by a registered electrical contractor — not just any tradesperson.
How long does a COC last?
A COC issued for a property transfer is valid for 2 years from the date of issue, provided no alterations have been made to the installation. If electrical work is carried out after the COC is issued, a new certificate is required for the affected circuits.
What happens if my property fails the inspection?
If faults are found during the inspection, we provide a detailed report of all non-compliant items and a transparent quote to carry out the remedial work. Once the work is completed, we re-inspect and issue the COC. We handle both the remedial work and re-inspection — no need to coordinate multiple contractors. We aim to complete this as quickly as possible to avoid delays to your property transfer.
How much does a COC inspection cost in the East Rand?
The cost depends on the size and complexity of the property. Residential inspections are priced per visit. If remedial work is required, this is quoted separately and transparently before any work begins — no surprises. Call 076 119 1500 or send a WhatsApp for a quote specific to your property.
Do I need a COC for solar panels or a battery inverter?
Yes. A COC is legally required for all grid-tied and hybrid solar installations in South Africa. The existing electrical installation must also be compliant before a solar COC can be issued. NOCD Technical handles both the solar installation and the associated COC — see our solar page for details.
Can you do a COC for an industrial or commercial property?
Yes. We issue COC certificates for residential, commercial and industrial properties. Industrial inspections cover 3-phase supply, MCC panels, earthing systems, motor control circuits and all fixed equipment under SANS 10142-1. For industrial properties across Apex, Jetpark, Alrode, Elsburg and Vorsterskroon — we have the equipment and certification to handle it.
My insurance company is asking for a COC — what do I do?
Contact us to book an inspection. We will inspect the installation, identify any non-compliant items, carry out remedial work if needed, and issue the COC. Most South African insurers require a COC issued by a registered contractor — we are fully registered and our certificates are legally recognised.
