Certificate of Compliance Electrician: Landlord Guide
Key takeaways
- A valid electrical Certificate of Compliance must be issued before any property in South Africa is sold or transferred.
- Only a registered person, an ETSP, IE or MIE registered with the Department of Employment and Labour, may legally issue a COC.
- For property transfer purposes a COC older than two years is not accepted, so landlords should keep theirs current.
- New electrical work, including a new aircon circuit, needs a supplemental COC certifying that specific installation.
- A COC confirms the installation meets SANS 10142-1, the national wiring code.
A Certificate of Compliance electrician is a registered professional who inspects your electrical installation and issues the legal document proving it is safe and meets national standards. In South Africa you need a valid COC before you sell or transfer a property, and only a registered person may issue one. This guide explains what the certificate covers, why landlords and sellers need it, and how adding an aircon affects your compliance.
If you own or manage rental property in Gauteng, the COC is one of those documents that sits quietly in a drawer until a sale, a new tenant, or an insurance claim brings it back into focus. Getting it right the first time saves you a scramble later.
What an electrical COC is and when it's legally required
A Certificate of Compliance is a document issued by a registered electrician confirming that the electrical installation on a property is safe and complies with the wiring code. It is not a sales gimmick. It is a legal requirement rooted in the Electrical Installation Regulations made under the Occupational Health and Safety Act 85 of 1993.
The clearest trigger is a change of ownership. The Department of Employment and Labour confirms that a valid COC must be obtained and provided prior to the sale or transfer of any property. In practice this means a conveyancing attorney or transferring agent will ask for the certificate before a deal can close.
You also need a COC when:
- You sell or transfer the property to a new owner.
- You carry out new electrical work or alterations to the installation.
- Your existing certificate is too old to be accepted for a transfer.
The certificate confirms your installation meets SANS 10142-1, the national wiring code, which is the standard every registered electrician tests against.
Why landlords and sellers need a valid COC
For sellers the reason is simple. Without a valid COC the transfer cannot proceed cleanly, and a last-minute inspection that turns up faults can delay a sale by weeks. Sorting the certificate early keeps your timeline in your own hands.
For landlords the picture is a little wider. The property owner carries responsibility for the safety of the installation. A current COC gives you documented proof that the wiring, distribution board and earthing were tested by a registered professional, which matters if a tenant raises a safety concern or an insurer questions a claim after an electrical fault.
There is a validity nuance worth knowing. A COC covers the lifetime of the installation while nothing changes, but for a property transfer a certificate that is older than two years is generally not accepted. The Electrical Contractors Association of South Africa notes that a change of ownership should not be allowed on a certificate older than two years. Landlords planning to sell within a few years benefit from keeping theirs reasonably fresh.
How aircon installs affect your compliance
This is where many property owners get caught out. Adding a split unit or a commercial system usually means new electrical work: a dedicated circuit, an isolator, and correct cabling back to the distribution board. That new work is an alteration to your installation, and alterations must be certified.
The Electrical Conformance Board is clear that additions or alterations require a supplemental COC. Your original certificate does not automatically extend to cover a new aircon circuit installed years later. If the wiring for that unit was never certified, a buyer's electrician can flag it during a pre-transfer inspection.
A few practical points for Gauteng property owners:
- A properly installed aircon should have its own circuit and isolator, not be run off an existing plug point or spliced into an unrelated circuit.
- If you inherited an aircon with no paperwork, treat its wiring as uncertified until an electrician tests it.
- Poor aircon wiring is a common finding on inspections, especially where an unregistered installer cut corners.
This is exactly why it pays to use an installer who employs registered electricians. When Airconmaster installs a unit, the same team can certify the electrical work, so you are not left chasing a second contractor to issue a supplemental COC.
What a Certificate of Compliance electrician inspects and certifies
Only a registered person may issue a COC. That means an Electrical Tester for Single Phase, an Installation Electrician or a Master Installation Electrician registered with the Department of Employment and Labour. Issuing a certificate on behalf of an unregistered individual is a criminal offence, which is why the registration status of your electrician genuinely matters.
During a COC inspection, an Airconmaster registered electrician typically checks:
- The distribution board, including the main switch, circuit breakers and labelling.
- Earthing and bonding, so faults trip safely instead of energising metalwork.
- Earth leakage protection and its correct operation.
- Wiring condition, polarity and correct connections at points and the board.
- Isolators and dedicated circuits for fixed appliances, including aircon units.
- Any obvious non-compliance against SANS 10142-1.
Where something fails, we explain the issue plainly and give you an upfront written quote for the repair before any work starts. Nothing gets certified until it is actually safe, and that standard is the same one we apply to every job.
Turnaround times and documentation you receive
Most residential COC inspections are completed in a single visit, provided the installation is in reasonable condition. If faults are found, the timeline depends on the repairs needed, and we agree those with you before proceeding rather than surprising you later.
When the installation passes, you receive the Certificate of Compliance itself. For a full property the electrician issues an initial COC covering the whole installation. Where the certificate relates to added or altered work, such as a new aircon circuit, you receive a supplemental COC covering that specific portion.
Keep the certificate somewhere safe with your property documents. Your conveyancer, a future buyer, or your insurer may all ask for it, and having it ready avoids repeat inspections.

Frequently asked questions
Who is legally allowed to issue an electrical COC?
Only a registered person, meaning an Electrical Tester for Single Phase, an Installation Electrician or a Master Installation Electrician registered with the Department of Employment and Labour. Anyone issuing a COC on behalf of an unregistered person is committing a criminal offence.
How long is a Certificate of Compliance valid in South Africa?
A COC is valid for the lifetime of the installation while nothing changes, but for property transfer a certificate older than two years is not accepted, so a fresh inspection is required.
Does installing an aircon require a new COC?
New electrical work such as a dedicated aircon circuit is an alteration to the installation, so a supplemental COC must be issued to certify that specific work.
Do landlords need a COC for a rental property?
The property owner is responsible for a valid COC, and it is required before transfer of ownership. Many landlords and estate agents also request one to prove the installation is safe for tenants.
