QUICK ANSWER
An electrical CoC does not have a universal two-year expiry date. The “two years” in regulation 7(5) applies when ownership changes: a user or lessor may not allow transfer if the certificate is older than two years. Additions or alterations also need suitable certification for at least the changed work.
Why so many people think every CoC expires after two years
Property transfers are when most homeowners are asked for a certificate, so the transfer condition is often repeated as if it were a general expiry rule. It is more accurate to ask two separate questions: Is ownership changing? Has the electrical installation been added to or altered since the existing certificate?
The age of the paper is not the only issue. A recent certificate cannot describe work done after it was issued, and an old installation can develop damage even if the records were once correct. Legal suitability, documentary coverage and current safety are connected but not identical.
The two-year change-of-ownership condition
Regulation 7(5) says the user or lessor may not allow a change of ownership if the CoC is older than two years. A certificate issued more recently still needs to relate to the installation that is actually being transferred. If the property changed afterwards, the later work needs its own appropriate certification and records.
Example: a CoC issued in 2019 may remain an important historical record for an unchanged installation, but it is older than two years for a transfer in 2026. That is why the seller should have the documents and property assessed before the conveyancing timetable becomes tight.
Selling or buying? Let a registered person assess the document trail and current installation rather than relying on the date alone.
Request a CoC inspectionWhat alterations do to the certificate record
Where additions or alterations are made, regulation 7(4) requires a certificate for at least the addition or alteration. In consumer language, think of the property as having a record set: the earlier certificate and test report, plus later certificates that cover changed work.
Typical changes worth checking include new plugs or circuits, a replacement DB board, a kitchen or outbuilding, pool or gate work, a stove connection, solar panels, an inverter, a generator or a supply-phase change. Do not assume a contractor’s invoice is the same as the required certificate and test documentation.
When should you arrange a fresh inspection?
- Ownership will change and the existing certificate is older than two years.
- The certificate or test report is missing, damaged or cannot be matched to the property.
- Electrical additions or alterations were made after the certificate date.
- There are signs of damage, overheating, repeated tripping, shock or unsafe work.
- A buyer, conveyancer, landlord, insurer or lender asks for a current assessment or document set.
- You need to understand the installation before solar, an inverter, an EV charger, a DB upgrade or major new load.
What a certificate does—and does not—prove
A properly issued CoC records that the registered person inspected and tested the relevant installation and was satisfied to issue at that time. Keep it with the approved test report. It is not a lifetime warranty against later damage, misuse, unauthorised alterations or changing site conditions.
It also does not ordinarily certify portable appliances, a gas installation or an electric-fence system. The electric fence has a separate regulatory certificate. Solar and inverter work may involve both electrical certification and a separate Eskom or municipal registration process.
| Situation | Is the date alone enough? | Practical next step |
|---|---|---|
| Transfer; CoC older than two years | No | Arrange an appropriate inspection/certificate before ownership changes. |
| No transfer; no known alterations | No universal two-year renewal rule | Keep the CoC/test report; act on safety concerns and stakeholder requests. |
| Later additions or alterations | No | Find the later certificate or have the changed work assessed. |
| Missing test report | No | Ask the issuer for records if possible or request an assessment. |
| Damage, tripping, heat or shock | No | Treat the symptom as a safety/fault issue; do not wait for a sale. |
IMPORTANT DISTINCTION
A certificate can be unsuitable for a transfer because of its age without every unchanged CoC “expiring” on a two-year cycle.
How to store the documents
- Keep the CoC and its test report together.
- Add later or supplementary certificates in date order.
- Keep solar/inverter diagrams, equipment documents and supplier correspondence separately but cross-referenced.
- Keep the electric-fence-system certificate separate from the ordinary installation CoC.
- Record the property address, issuing person, issue date and contact details.
- Give copies to the appropriate buyer, landlord, body corporate or professional when required.
Common questions
- Does a CoC automatically become invalid after two years?
- No. The widely quoted two-year condition is tied to change of ownership, not a blanket renewal requirement for every property.
- What if no electrical work was done after the old certificate?
- Keep the certificate and test report. If ownership will change and it is older than two years, the transfer rule still requires attention.
- Can I use the same certificate after installing solar?
- The existing document cannot automatically cover later work. The solar/inverter addition needs suitable electrical certification and may also require supplier registration.
- What if I lost the certificate?
- Try the issuing contractor or records held by parties to the prior transaction. If it cannot be recovered, ask a registered person what assessment is needed.
- Does an insurer always require a certificate less than two years old?
- Insurance requirements depend on the policy and the facts. Ask the insurer or broker directly and avoid assuming the property-transfer rule is an insurance rule.
Unsure whether your current CoC is suitable? Tell Welvaart the certificate date, whether the property is being transferred and what work was added later.
