Electrical certificate of compliance when selling a house in South Africa

What is an electrical certificate of compliance?

An electrical certificate of compliance — a COC — is a signed declaration by a registered electrician that a property's fixed electrical installation has been inspected and complies with SANS 10142-1, the South African wiring code. It certifies the installation, not the seller: the wiring, the distribution board, the earthing and the earth-leakage protection.

Only an electrician registered with the Department of Employment and Labour may issue one, and only after physically inspecting and testing the installation — a certificate issued sight-unseen is not a certificate. The document carries the electrician's registration details and the date of issue, and it is valid for two years from that date. Buyers use it as evidence that the wiring behind the walls was professionally assessed before they took ownership.

Is an electrical COC required when selling a house?

Yes. The Electrical Installation Regulations, 2009 — made under the Occupational Health and Safety Act 85 of 1993 — require the seller to be in possession of a valid certificate of compliance for the electrical installation and to furnish it to the buyer when the property is delivered. This applies to every private-property sale, not only to newer homes or estate properties.

In practice the requirement is locked into the transaction: the offer to purchase almost always obliges the seller to deliver a valid COC, estate agents ask for it at listing stage, and the conveyancer needs it in the file before registration. If you sell without planning for it, the inspection — and any repairs it uncovers — becomes the thing that stalls the transfer in its final weeks.

How long is an electrical certificate of compliance valid?

Two years from the date of issue — provided the electrical installation has not been altered or extended since the certificate was signed. A certificate older than 24 months, or one issued before changes to the wiring, does not satisfy the seller's obligation to furnish a valid certificate.

The "while unchanged" part is what sellers trip on. If you have added circuits, replaced the distribution board, rewired a section, or installed equipment that ties into the electrical installation — a solar inverter or a heat pump, for example — since the certificate was issued, the installation no longer matches the document. The safe reading is simple: if the installation has changed, get a fresh inspection and a new certificate before you sell. If in doubt about an existing certificate's status, ask the electrician who issued it.

Can a house be transferred without an electrical COC?

No. A valid COC is one of the standard compliance documents the conveyancer requires before the transfer can be registered at the Deeds Office — alongside the rates clearance certificate and, where applicable, the other compliance certificates. The registration cannot simply proceed and the certificate be "sorted out later".

If the certificate is missing, or the inspection reveals wiring that must be repaired before the electrician will sign, the registration date slips — and the buyer, the seller and both banks wait on one electrician's quote. That delay has real costs: occupational rent arrangements, expiring interest-rate guarantees, and a buyer whose own bond starts looking uncertain. Where the buyer's side needs certainty, the sale agreement should say exactly who arranges, pays for and fixes the certificate.

What does the electrician check?

The inspection tests the fixed installation against SANS 10142-1: the distribution board, the condition of the wiring, the earthing and bonding, and the earth-leakage protection. Common checks include:

• Earth-leakage units trip correctly. A unit that does not trip within the standard's limits is the most common failure point in older homes.
• The distribution board is sound and correctly labelled — no damaged covers, no mixed-up breakers, no unlabelled circuits.
• Circuit breakers match the wiring they protect so that overloaded circuits actually cut out.
• Earthing and bonding are present and continuous on the main board and on metalwork such as geysers and metal water pipes.
• Visible wiring, socket outlets and switches are in a safe condition — no burned fittings, no exposed conductors, no DIY splices.

If the inspection finds non-compliant items, the electrician quotes the repairs separately; the certificate is issued only once the failures are fixed. That repair step — not the inspection itself — is where most of the time and cost goes.

How much does an electrical COC cost?

There is no fixed national price for an electrical COC — the cost varies by electrician, property size and the condition of the installation, and any repairs needed to pass are quoted separately. bond.co.za deliberately quotes no rand figures here: inspection rates are set per electrician, and repair costs depend entirely on what the inspection finds.

Three practical rules keep the cost honest. First, use only an electrician registered with the Department of Employment and Labour — check the registration before you book. Second, get written quotes from more than one registered electrician; call-out rates and inspection fees differ widely. Third, treat a certificate offered without a genuine inspection as worthless — the seller, not the electrician, carries the risk when a paper-only certificate fails scrutiny in the transfer file. Budget for repairs, not just the inspection: in older homes the repairs are usually the larger of the two.

Who pays for the electrical certificate of compliance?

By convention the seller pays: the obligation to furnish a valid COC sits with the seller, and the offer to purchase almost always allocates the inspection and any repairs to the seller's account. The seller is the party delivering the compliant property, so the cost of delivering it follows.

But it is a contract term, not a commandment: the parties can allocate the cost differently, and buyers competing hard for a home sometimes offer to carry it. Read your offer to purchase before you sign — the offer to purchase guide explains which clauses deserve a second look. If the agreement is silent on the COC, the legal obligation to furnish one still sits with the seller.

What other compliance certificates do you need when selling?

Depending on the property and the sale agreement, sellers may also need an electric fence certificate (if there is a system), a gas installation certificate (if there is bottled or piped gas) and a beetle or wood-borer clearance certificate (mainly coastal areas, where the agreement requires it). Each is a separate document from a separate inspector — the electrician's COC does not cover them.

Separately from certificates, the Property Practitioners Act, 2019 requires the seller's mandatory written disclosure of known defects when a property is marketed — the days of selling strictly voetstoots, defects and all, are gone. The voetstoots clause guide explains how that changed. For the certificates themselves, your offer to purchase is the working checklist: it should name exactly which certificates the seller must deliver, for whom, and by when.

An electrical COC is not a rates clearance certificate

They are different documents from different sources: the COC proves the wiring was inspected and complies with the wiring code; the rates clearance certificate proves the municipal account for rates and services is paid up. Transfers typically need both in the file, and sellers routinely mix them up because both arrive in the final weeks before registration.

The electrician issues the COC after inspection; the municipality issues the clearance certificate after the account is settled (usually with an advance payment of a few months' rates). The rates clearance certificate guide covers the municipal side — how the advance payment works and the lead time to build in.

When should you get the COC in the transfer timeline?

Book the inspection early — ideally as soon as the offer to purchase is signed, or before listing if you already know the wiring is dated — because repairs, if needed, take longer than the inspection itself. The certificate is delivered to the conveyancer before registration; arranging it in the last week is how transfers slip.

The sequence in a typical sale: offer signed → electrician books and inspects → repairs quoted and done → COC issued to the conveyancer → registration at the Deeds Office, where the certificate sits in the file alongside the rates clearance. The property transfer process guide maps the full timeline, and the selling a house with an outstanding bond guide shows where the sale proceeds actually go on registration day.

And if selling is the front half of a move: your next bond does not have to stay with your current bank. Bond switching can put the new loan out to tender and secure a better rate.

Sources and assumptions in this guide

The legal requirements referenced here are the Electrical Installation Regulations, 2009 (promulgated under the Occupational Health and Safety Act 85 of 1993) — the source of the seller's obligation to furnish a valid certificate and of the two-year validity period — and SANS 10142-1, the South African wiring code the inspection tests against. The disclosure duty referenced is from the Property Practitioners Act, 2019. Conveyancing practice statements — that the conveyancer requires the certificate before registration, and that the seller typically pays — describe standard practice, not statutes.
