Direct answer
A South African electrical Certificate of Compliance (CoC) is a formal certificate, accompanied by a test report, confirming an electrical installation or relevant work has been inspected and tested by a registered person against the applicable requirements. The commonly repeated statement that a CoC “expires after two years” is incomplete: the Electrical Installation Regulations specifically prohibit a change of ownership when the CoC is older than two years. Alterations or additions create separate certification obligations.
Key facts
- Regulation 7(1) requires the user or lessor of an electrical installation to have a valid CoC, subject to the stated exceptions.
- Regulation 7(4) says that when an addition or alteration is made to an installation that already has a CoC, a CoC must be obtained for at least that addition or alteration.
- Regulation 7(5) is the source of the “two-year rule”: ownership may not change if the CoC is older than two years.
- Regulation 9 says only a registered person may issue a CoC and only after inspection and testing establish the required condition.
- The Department of Employment and Labour warned in October 2025 about complaints involving non-compliant installations despite CoCs and urged owners to use competent, legally registered contractors.
What a CoC is — and what it is not
The Electrical Installation Regulations, 2009 define a certificate of compliance as a certificate with a unique number, issued by a registered person in respect of an electrical installation or part of an installation.[1] Regulation 7 requires the certificate to be accompanied by the prescribed test report.
A CoC is therefore not a generic “electrician invoice”, warranty or visual check. Its value comes from verification and testing by a registered person. Nor should it be treated as a promise that nothing can ever fail after the certificate is issued; electrical equipment can deteriorate or be altered later.
Does an electrical CoC expire after two years?
The regulation does not state that every CoC automatically becomes invalid two years after issue. Regulation 7(5) states that the user or lessor may not allow a change of ownership if the CoC is older than two years.[1] That is a transfer-of-ownership requirement.
This distinction matters. A homeowner who has owned a property for longer than two years is not automatically told by Regulation 7(5) to renew a certificate every 24 months simply because time passed. However, alterations, defects and a future property transfer can create a need for additional or new certification.
What happens after electrical alterations?
Regulation 7(4) says that when an addition or alteration is made to an installation for which a CoC was previously issued, the user or lessor must obtain a CoC for at least the addition or alteration.[1] Examples can include new circuits, changes to fixed wiring or other installation work, depending on the scope.
This is one reason it is important to retain certificates and test reports. A property can accumulate a compliance history: the original certificate plus later certificates covering legitimate additions or alterations.
Who is allowed to issue the CoC?
Regulation 9 states that no person other than a registered person may issue a CoC. It also requires the registered person to satisfy themselves, by inspection and test, that the relevant installation meets the applicable requirements before issuing the certificate.[1]
The Department of Employment and Labour repeated this position in October 2025, advising property owners and businesses to use competent and legally registered electrical contractors and warning against certificates issued on behalf of unregistered individuals.[2]
What standard is being used in 2026?
ECA(SA) notified industry of the availability of SANS 10142-1:2026 Edition 3.03 in June 2026.[3] SANS 10142-1 is a central South African wiring-code reference for low-voltage installations. The standard is copyrighted; responsible public-facing content should explain principles and point readers to authorised standards access rather than reproduce tables or clauses in bulk.
When should a buyer or homeowner ask more questions?
A CoC deserves further scrutiny when major electrical work appears to have been completed after the certificate date, when DB labelling does not match the installation, when obvious defects or exposed wiring are present, when solar/backup systems have been added without clear documentation, or when the certificate cannot be linked to a registered person.
If a defect is detected during an inspection, Regulation 7(7) allows an inspector, approved inspection authority or supplier to require a new CoC. In serious danger situations, the regulations also provide for disconnection steps.[1] The correct lesson is not that “a CoC is meaningless”; it is that the certificate works within an inspection, testing and accountability system.
Common CoC statements: accurate or misleading?
| Statement | Assessment | Why |
|---|---|---|
| “A CoC expires every two years.” | Misleading | The two-year wording in Regulation 7(5) is specifically tied to a change of ownership. |
| “Any electrician can issue a CoC.” | Incorrect | The regulations reserve issuance to a registered person. |
| “An alteration can be covered without any new paperwork.” | Incorrect in general | Regulation 7(4) requires certification for at least the addition or alteration. |
| “A CoC means the installation was inspected and tested.” | Correct in principle | Regulation 9 requires inspection and testing before issue. |
| “A CoC guarantees nothing can fail later.” | Incorrect | A certificate verifies condition/compliance at the relevant point; later deterioration or alterations can occur. |
Frequently asked questions
Do I need an electrical CoC to sell my house?
For a change of ownership, the user or lessor may not allow transfer if the CoC is older than two years. The Department of Employment and Labour also states that a valid CoC must be provided prior to sale or transfer.
Does my CoC become useless after two years if I am not selling?
The two-year clause is specifically tied to change of ownership. Other events — particularly additions, alterations or detected defects — can require additional or new certification.
Can the person who did the electrical work issue the CoC?
Only if that person is appropriately registered and satisfies the regulatory requirements for inspection, testing and certification.
Do solar or inverter additions affect the CoC?
They can involve alterations/additions to the electrical installation. The exact certification and embedded-generation requirements depend on the system and local authority, so have the work handled and documented by appropriately competent professionals.
Can Whitehouse issue a CoC because it sells electrical products?
Retail sale of electrical products is not the same as being the registered person who inspects, tests and certifies a fixed installation. Do not imply certification services unless Whitehouse actually provides them through properly registered personnel.
