An Electrical Certificate of Compliance (COC) is a legal document that certifies your home or building's electrical installation meets the required safety standards. In South Africa, it's not just good practice — it's the law.
What Does a COC Cover?
A COC is issued by a registered electrical contractor after a thorough inspection of the electrical installation. The inspection covers:
- Distribution board (DB board) condition and labelling
- Wiring integrity and insulation
- Earth leakage protection (ELCB/RCCB)
- Correct circuit protection (breakers rated correctly)
- Proper earthing and bonding
- Condition of plugs, switches, and light fittings
When Do You Need a COC?
- Selling your property: A valid COC is legally required to transfer property ownership.
- After electrical work: Any new installation or significant alteration requires a new COC.
- New rental agreements: Landlords must provide tenants with a valid COC.
- Insurance claims: Many insurers require a valid COC to process claims related to electrical damage or fire.
- New builds: A COC is required before the local authority will approve a building completion certificate.
How Long Is a COC Valid?
A COC is valid for the specific installation at the time of issue. If any electrical work is done after the COC is issued, a new one is required. There is no fixed expiry date, but the COC becomes invalid if the installation changes.
What Happens if You Don't Have One?
- You cannot legally sell or transfer the property
- Your insurance may not cover electrical damage or fire
- You may be held liable if someone is harmed by an unsafe installation
- Tenants have the right to request a valid COC before occupation
The Inspection Process
A registered electrical contractor will test and inspect the installation, identify any faults or non-compliant items, and issue a repair list if needed. Once all issues are resolved, the COC is issued. The contractor is responsible for the accuracy of the certificate — so using a registered professional is essential.
Key takeaways
- A COC certifies your electrical installation is safe and compliant
- Required for property sales, new rentals, and after electrical work
- Only a registered electrical contractor can issue a COC
- No fixed expiry, but any new work invalidates the existing COC
- Not having one when required is a legal and insurance risk
