Few documents cause as much last-minute panic in a property deal as the electrical certificate of compliance. In South Africa, an electrical certificate of compliance (COC) is a legal requirement, not a nice-to-have: every property with a fixed electrical installation must be covered by one, and if you let the property out, the duty to hold that certificate sits squarely with you as the lessor. This guide walks through what the COC actually certifies, when you need a new one, who is allowed to issue it, what the inspection involves, and how landlords and property managers can keep a whole portfolio compliant without drama.
What an electrical certificate of compliance in South Africa actually certifies
A COC is issued in terms of the Electrical Installation Regulations, made under the Occupational Health and Safety Act. It certifies that the fixed electrical installation of a property is reasonably safe and complies with the applicable wiring standard, SANS 10142-1.
Two points trip people up constantly:
- The COC covers the fixed installation only. That means the distribution board, circuit breakers, earth leakage protection, fixed wiring, socket outlets, light fittings, isolators and the electrical connection to the geyser. It does not cover plug-in appliances, and it does not cover an electric fence, which needs its own separate electric fence system certificate.
- A COC is a certificate plus a test report. The certificate on its own, without the accompanying test report recording the actual test results, is incomplete. When you receive one, check that both parts are there and file them together.
The legal duty on landlords and lessors
Under the Electrical Installation Regulations, every user or lessor of an electrical installation must be in possession of a valid COC. Read that again as a landlord: the tenant may be the one flipping the switches, but the legal duty to hold the certificate rests with the lessor. You cannot shift it onto the tenant through a clause in the lease.
You may be asked to produce the certificate by an inspector from the Department of Employment and Labour or by the electricity supplier. It also matters enormously at claim stage: after an electrical fire, insurers routinely interrogate the state of the installation, and a missing or invalid electrical certificate of compliance in South Africa can complicate or sink a claim entirely.
For agencies and portfolio landlords, this is a record-keeping problem as much as a legal one. Tracking which properties hold a current certificate, and which have had alterations since it was issued, is exactly the kind of admin that job management tools built for property managers exist to tame.
When you need a new COC
A COC does not carry a blanket expiry date, but several triggers require a fresh or supplementary certificate:
- Sale and transfer of the property. For transfer, the COC must not be older than two years at the date of transfer, and there must have been no alterations to the installation since it was issued. Conveyancers and banks will not let the deal through without it.
- Alterations or additions. New circuits, extra plug points, a rewired geyser connection, or a solar and inverter installation all change the fixed installation. The altered work must be certified, typically with a supplementary COC covering the new work.
- No certificate exists. Older properties sometimes have no COC on record at all. As the lessor you are required to hold a valid one, so this needs fixing before a tenant moves in, not after an incident.
- After significant electrical repairs. If a fault required rework of the fixed installation, get the repair certified.
- At tenant changeover, as good practice. The law does not demand a new COC per lease, but a quick verification between tenants is cheap insurance against inheriting a tenant's DIY handiwork undetected.
The rise of solar and backup power installations deserves special mention. Any inverter or PV system wired into the fixed installation forms part of it, and an installation altered by a solar fitment without certification can invalidate your compliance position. Always insist the installer provides the certificate for their work.
Who may issue an electrical COC
Only a registered person - an electrical contractor registered with the Department of Employment and Labour - may lawfully test an installation and issue a COC. Registration comes in categories, from electrical tester for single phase up to installation electrician and master installation electrician, and the category must match the type of installation being certified.
Be careful here. A person can be a skilled, qualified electrician without being registered to issue certificates. A certificate from an unregistered handyman is worthless: it will not survive scrutiny at transfer, from an inspector, or from an insurer. Before booking anyone:
- Ask for their registration details and category.
- Confirm the registration is current, not lapsed.
- Confirm the person doing the test is the registered person, not an unregistered assistant working under a borrowed name.
What the inspection and test involves
A proper COC inspection is not a walk-through with a torch. Expect the electrician to carry out, at minimum:
- A visual inspection of the distribution board, its labelling, and the general condition of visible wiring and fittings.
- Earth continuity and bonding tests, including bonding of the geyser and exposed metal parts.
- Insulation resistance testing of circuits.
- Polarity checks at socket outlets.
- A functional test of the earth leakage protection, including its trip performance.
If faults are found, the electrician should give you a written list and a separate quote for the remedial work. The certificate is only issued once the installation actually passes - a COC issued despite known defects is fraudulent and protects nobody.
Common reasons rental properties fail
Across rental stock, the same culprits come up again and again:
- Missing, bypassed or faulty earth leakage protection.
- Unbonded geysers and metal pipework.
- DIY circuits added by tenants or previous owners, often feeding outbuildings, Wendy houses or garden cottages.
- Damaged or degraded wiring and perished insulation.
- Broken socket outlets, missing blanking plates and unlabelled distribution boards.
- Uncertified solar, inverter or generator changeover installations.
None of these are exotic, and most are inexpensive to fix relative to the risk they carry. The expensive version is discovering them during a transfer with a transfer date looming, when you have no negotiating power on price or timing.
Validity, the two-year rule and record keeping
To restate the rule that causes the most confusion: an electrical certificate of compliance in South Africa remains valid indefinitely as long as no alterations are made to the installation, but for purposes of transferring the property it may not be older than two years. Landlords holding property long-term should therefore keep the original certificate safe, log the date of every electrical alteration, and file each supplementary COC alongside the original.
Keep digital copies attached to each property's record. When a sale, an insurance claim or an inspector's visit arrives, you want retrieval to take minutes, not a frantic call to an electrician who certified the place years ago.
How to arrange a COC inspection without the runaround
When a certificate is due, the process is straightforward if you sequence it properly:
- Dig out any existing COC and test report, plus records of alterations since it was issued.
- Get quotes from two or three registered electricians, and verify registration before you compare prices. Platforms like PlanaJob let property managers compare quotes from vetted contractors side by side, which takes the guesswork out of this step.
- Book the inspection and arrange tenant access with reasonable notice.
- If the installation fails, review the fault list and remedial quote separately - you are entitled to have the remedial work done by a different contractor if you prefer.
- On completion, receive the certificate and test report together, and file both against the property.
If you manage multiple properties, standardise this as an annual review task rather than a panic response to a sale. You can book a registered electrician for your COC inspection through PlanaJob in minutes - create a free account and post the job with your property details and preferred dates. And if you are an electrician reading this, compliance certificates are one of the most reliable door-openers into ongoing property maintenance work - there is solid thinking on building that kind of repeatable revenue into a trade business over at Construction Arbitrage.

FAQ
How long is an electrical certificate of compliance valid in South Africa?
There is no blanket expiry date. A COC remains valid for as long as no alterations are made to the fixed electrical installation. The two-year limit applies specifically to property transfers: at the date of transfer the certificate must not be older than two years, and no alterations may have been made since it was issued.
Who pays for the COC - the landlord or the tenant?
The legal duty to be in possession of a valid COC rests on the lessor, so the cost of obtaining the certificate normally sits with the landlord. In a sale, the seller customarily pays for the certificate and any remedial work needed to obtain it. Where a tenant has damaged the installation or made unauthorised alterations, a well-drafted lease can allocate those specific remedial costs to the tenant.
Can I let a property without a valid COC?
No. The Electrical Installation Regulations require every lessor to hold a valid certificate, so letting without one puts you in breach regardless of whether anything ever goes wrong. It also exposes you badly if it does: an insurer assessing a fire or electrocution claim will ask for the certificate first, and its absence can prejudice the claim and your personal liability position.
