What is an electrical Certificate of Compliance?
An electrical Certificate of Compliance (COC) is a legal document, issued by a registered electrician, certifying that an electrical installation conforms to the South African National Standard SANS 10142-1 — the wiring code of practice for the country.
It's not a warranty. It's a snapshot saying that on the date it was issued, the installation was safe and compliant. Subsequent alterations require their own COC for the altered work.
The legal framework
The Electrical Installation Regulations 2009, made under section 43 of the Occupational Health and Safety Act 85 of 1993, set out the rules. The relevant clauses for homeowners:
- Regulation 7 — anyone supplying electricity to an installation (which includes selling a property) must possess a valid COC for that installation.
- Regulation 9 — only a registered person may issue a COC.
- Regulation 8 — a COC must not be more than 2 years old at the time of transfer, and must reflect the current state of the installation.
When you legally need a COC
| Situation | COC required? |
|---|---|
| Selling a property | Yes — within 2 years of issue, reflecting the current installation |
| Any new electrical installation (new build) | Yes — before electricity can be supplied |
| Any alteration to an existing installation (new circuit, new socket, DB-board upgrade, etc.) | Yes — for the altered work |
| Replacing a faulty switch or socket with the same spec | No — "like-for-like" replacement is excluded |
| Renting out a property | No statutory requirement, but most insurers expect one |
| Insurance claim involving electrical damage | Most insurers will request a current COC |
Property transfer + COC
This is where most homeowners discover their installation isn't compliant — at the worst possible time, with a sale agreement on the table.
Your conveyancing attorney cannot lodge the transfer with the deeds office unless you can produce a COC less than 2 years old. If your existing COC has expired, or you've made undocumented alterations (more common than you'd think — extra plug points, garden lights, pool pump wiring), you'll need a new inspection and any remedial work done before the sale can proceed.
Budget for a 1–4 week delay if you discover the issue late. The cost of remedial work to make a typical home compliant ranges from R0 (clean inspection) to R15,000–R30,000 for older homes with non-compliant DB boards, inadequate earthing, or outdated wiring.
Insurance claims + COC
Most South African home insurance policies require a valid COC when assessing claims involving:
- Electrical fire or fire suspected of electrical origin
- Faulty geyser element causing water damage or burnout
- Surge damage to appliances (lightning, grid spikes)
- Damage to wiring (e.g. from rodents or building work)
If your COC is missing, expired, or the work was done by an unregistered person, claims are commonly rejected. Keep your COC, the installation invoice, and any subsequent alteration certificates filed together — physically and digitally.
What a COC inspection covers
A registered electrician will check, at minimum:
- DB board layout, labelling, and breaker ratings against the cable they protect
- Earth-leakage protection (RCD/ELU) — present, correctly rated, and functional
- Earthing of all socket outlets, geyser, and the main bonding
- Polarity of all circuits
- Insulation resistance on all circuits
- Geyser installation (correctly bonded, drip tray, vacuum breaker, isolator)
- Outdoor circuits (correct IP rating, weatherproofing, RCD protected)
- Bathroom zoning rules (no sockets within reach of bath, correct IP rated fittings)
What does a COC cost?
Inspection only (no remedial work needed): R1,200–R2,500 in major SA metros in 2026. Smaller towns: R800–R1,800.
If remedial work is found, the electrician issues a written report and quotes for the fixes. Common remedial costs:
- Adding earth-leakage protection where missing: R800–R1,800
- Replacing a non-compliant DB board: R3,500–R8,000
- Re-earthing socket outlets: R150–R300 per outlet
- Geyser bonding / drip tray fix: R600–R1,500
Consequences of not having one
- You cannot sell the property until you produce one.
- Insurance claims related to electrical damage are commonly rejected.
- If your installation causes a fire that damages a neighbour's property, your public liability cover may be voided.
- Banks may refuse to grant a bond against a property without a current COC.
