Why You Need a COC to Sell Your House
If you are planning to sell your property in South Africa, an electrical compliance certificate is not optional, it is a legal requirement. The COC confirms that the electrical installation on your property is safe and compliant with South African national standards, specifically SANS 10142-1 (the wiring code for residential premises).
No conveyancing attorney will register a property transfer at the Deeds Office without a valid electrical certificate for selling property. This requirement exists to protect both the buyer and the seller, ensuring that the new homeowner moves into a property with a safe electrical system, and that the seller is not held liable for electrical faults after the sale.
Many sellers ask: "Do I need a COC to sell a house in South Africa?" The answer is an unequivocal yes. Whether you are selling a small apartment in Centurion, a family home in Pretoria East, or a large estate in Midrand, the property transfer COC requirements apply to every residential sale.
What you need to know
- A valid COC is required by law before a property can be transferred to a new owner
- The seller is responsible for obtaining and paying for the COC
- Without a COC, the conveyancing attorney cannot register the transfer at the Deeds Office
- The COC covers the fixed electrical installation, not portable appliances or equipment
- Non-compliance can delay your property sale by weeks or even months
Legal Requirements Under OHSA
The legal basis for the COC requirement comes from the Occupational Health and Safety Act (OHSA), Act 85 of 1993, and the Electrical Installation Regulations of 2009. These regulations make it mandatory for any property owner to ensure that their electrical installation is safe, properly maintained, and inspected by a registered person before the property changes hands.
Under these regulations, the COC requirements for selling a house include the following key legal obligations:
Regulation 7(1), Mandatory Certificate
No electrical installation may be connected to the electricity supply unless a valid COC has been issued. When ownership of a property is transferred, the seller must provide the buyer with a valid COC.
Regulation 7(2), Two-Year Validity
A COC remains valid for a maximum of two years from the date it was issued. If your existing COC has expired, a new inspection and certificate are required before the property can be sold.
Regulation 8, Registered Persons Only
Only a person registered with the Department of Employment and Labour in terms of Regulation 8 may inspect and issue a COC. Certificates issued by unregistered individuals are invalid and have no legal standing.
SANS 10142-1 Compliance
The electrical installation must comply with SANS 10142-1, which covers everything from wiring methods and earthing to circuit protection, DB boards, and socket outlets. This is the standard against which your property will be assessed.
Failure to comply with these regulations is a criminal offence. Sellers who proceed without a valid COC, or who provide a fraudulent certificate, can face prosecution, fines, and civil liability if an electrical incident occurs after the sale.
Who Can Issue a COC Certificate?
Not just any electrician can issue a valid electrical compliance certificate for a property sale. To legally inspect an electrical installation and issue a COC, the electrician must be:
Registered with the Department of Employment and Labour
The electrician must hold a valid registration certificate. You can verify their registration status by requesting their registration number.
Qualified as a Master Installation Electrician
COCs can only be issued by electricians who hold a wireman's licence or equivalent qualification and are registered in the appropriate category.
Competent to Perform Testing
The registered person must have access to calibrated testing equipment and be competent to perform the full range of tests required by SANS 10142-1.
Covered by Professional Liability Insurance
A reputable electrician will carry professional indemnity and public liability insurance to protect both themselves and the property owner.

What the Inspector Checks
During a COC inspection, the registered electrician will conduct a thorough assessment of the entire fixed electrical installation on the property. This typically takes 2 to 4 hours for a standard residential home and includes both visual inspection and instrument testing. Here is what the inspection covers:
What the COC Does NOT Cover
The COC only covers the fixed electrical installation, wiring, DB board, sockets, switches, light fittings, and permanently connected appliances like geysers. It does not cover portable appliances like kettles, microwaves, or extension cords. Buyers wanting those checked need a separate appliance test.
What Happens If Your Property Fails?
If the electrical installation on your property does not meet SANS 10142-1 standards, the inspector cannot issue a COC. Instead, you will receive a detailed non-compliance report listing all the defects and faults that need to be rectified before the certificate can be issued.
This is actually quite common, especially in older homes built before current standards were in place. Here is what happens next:
You Receive a Detailed Report
The electrician will document every non-compliance found during the inspection. Each item will reference the specific SANS 10142-1 clause that has been contravened.
You Get a Repair Quotation
Along with the report, you will receive a quotation for the repair work needed to bring the installation up to standard. At INC Unlimited, we provide transparent, itemised quotes with no hidden costs.
Repairs Are Carried Out
Once you approve the quotation, the registered electrician carries out the necessary repairs. This could range from minor fixes (a few hundred rand) to significant work (rewiring, DB board replacement) depending on the condition of the installation.
Re-Inspection and COC Issuance
After the repairs are completed, the electrician conducts a re-inspection to verify that all non-compliances have been resolved. Once everything passes, the COC is issued, typically within 24 to 48 hours.
It is strongly recommended to arrange your COC inspection well before you list your property for sale. This gives you time to address any non-compliances without the pressure of a pending transfer deadline.
How Long is a COC Valid?
Under the Electrical Installation Regulations, an electrical compliance certificate is valid for two years from the date it was issued. If you obtained a COC within the past two years and no major electrical work has been done to the property since, that certificate may still be valid for your property sale.
However, there are important conditions that can invalidate a COC before the two-year period expires:
Pro Tip for Sellers
Even if your existing COC is still valid, it is worth having a quick pre-inspection done before listing your property. Standards and enforcement have tightened over the years, and an older COC may have been issued under less stringent conditions. A fresh inspection gives buyers and their conveyancers confidence in the property.
Common Issues Found During Pre-Sale Inspections
Having inspected hundreds of properties across Pretoria and Gauteng, our electricians at INC Unlimited see the same problems come up time and again. Being aware of these common non-compliances can help you prepare and potentially save thousands of rands in last-minute repair costs.
| Common Issue | Severity |
|---|---|
| No earth leakage protection (RCD) or faulty ELCB | Critical |
| Unlabelled or incorrectly labelled DB board | Moderate |
| Missing or broken earth connections | Critical |
| Exposed or damaged wiring | Critical |
| Incorrect circuit breaker sizing | High |
| Unprotected outdoor wiring or junction boxes | High |
| Illegal or uncertified DIY electrical work | Critical |
| Missing bonding on water pipes or geyser | Moderate |
| Non-compliant pool pump installation | High |
| No surge protection installed | Low–Moderate |
Severity levels indicate the typical impact on COC issuance. Critical issues must be resolved before a COC can be granted.
Tips for Sellers: Preparing for a COC Inspection
A little preparation can go a long way toward ensuring a smooth COC inspection and avoiding costly surprises. Here are our top recommendations for sellers preparing to put their property on the market:
Book Your Inspection Early
Do not wait until you have an offer on the table. Book your COC inspection as soon as you decide to sell, ideally 4 to 6 weeks before listing. This gives you time to address any issues without delaying the transfer.
Check Your DB Board
Take a look at your distribution board. Are the circuit breakers labelled? Is everything neat and tidy? Are there signs of overheating, corrosion, or loose wiring? If your DB board looks old or neglected, it is likely to flag issues during the inspection.
Address Known Problems
If you know about flickering lights, tripping breakers, or sockets that do not work, get them fixed before the inspection. Known faults will almost certainly result in non-compliance findings.
Ensure Access to All Areas
The inspector needs access to the DB board, roof space, all rooms, outdoor areas, pool equipment, and any outbuildings. Make sure these areas are accessible and not blocked by furniture or stored items.
Disclose Any DIY Work
If you or a previous owner did any electrical work without using a registered electrician, disclose this upfront. Uncertified work is one of the most common reasons for COC failure and will need to be assessed and potentially redone.
Keep Previous COC Documentation
If you have a COC from a previous inspection, have it ready for the electrician. It helps them understand the history of the installation and identify what may have changed since the last certification.
