Electric fence installation near me: planned, built and signed off

• Wall-top. Brackets fixed along the top of a boundary wall carry the live lines, between six and twelve in the price lists below. It's what most homes have, because the wall already does the job of a barrier.
• Freestanding. The fence stands on its own posts with many more lines, 18 to 30 in the same lists, for open boundaries, smallholdings and business premises.
• On top of another fence. An electric section can run along the top of a palisade or weld-mesh fence, kept electrically separate from the steel, which is earthed.

More lines cost more per metre but are harder to climb through, and a freestanding fence costs more per metre than a wall-top one, as the prices below show. The choice comes down to the boundary you have, how exposed it is, and whether the fence has to stand alone.

The energiser powers the fence and watches it: when a wire is cut, shorted or earthed, it sounds the alarm. Planning it means three choices:

1. How many zones. A short suburban wall can run as one zone. A long boundary is split into two or more, so an alarm tells you which stretch to check; energisers come in single- and multi-zone models.
2. Which energiser. We fit Nemtek and JVA energisers, sized to the fence's length and number of zones. Our energiser page compares them.
3. What it connects to. A siren and strobe light on site, a keypad by the door to arm and disarm it, magnetic switches on the gates, and the alarm panel, so your armed response company sees a fence alarm. Nemtek's installer notes say the alarm panel connects through an isolation relay, and never runs from the energiser's own battery.

The energiser has its own back-up battery, so the fence stays live and monitored through a power cut. It needs a plug point close by; a new point is a job for a registered electrician.

Electric security fences are built to the standards that Nemtek's and JVA's installation manuals cite and summarise: SANS 10222-3 for the fence in South Africa, IEC 60335-2-76 for the energiser, and, in JVA's manual, SABS 1063 and 0142 too. In plain terms:

• Warning signs at every gate and access point and at least every 10 m, readable from both sides, with at least one on each side of the fence. Each is at least 100 × 200 mm, yellow on both sides, with black lettering at least 25 mm high saying the substance of "CAUTION: Electric fence".
• No barbed or razor wire electrified, or fixed close to the electric lines: it can trap a person or an animal.
• One energiser per fence. Two fences on different energisers stay at least 2.5 m apart, unless a barrier separates them.
• Gates must open without the person opening them getting a shock.
• Earthing. The fence's earth electrode sits at least 10 m from any other earth system, and where a fence passes under bare power lines, its metal is earthed for at least 5 m either side.
• Cabling. The high-voltage leads run in their own conduit, never alongside mains or alarm wiring, insulated indoors and in insulating conduit underground.

Certified electric fence installer. A fence we build is checked against these rules before we hand it over with the certificate, and if you're selling, buying or adding to a fence, electric fence certificates explains the inspection.

1. Site visit. We walk the boundary with you: its length and height, the state of the wall, the gates, any neighbour's electric fence nearby, where the energiser and its plug point will go, and where the earth spikes can be driven in.
2. Quote. The design, the number of lines and zones, the energiser and the extras, priced in writing before any work starts.
3. Brackets and insulators along the wall or posts, at an even spacing.
4. Wire. Strung, tensioned and joined only with ferrules or line clamps; Nemtek's installer notes warn against mixing metals, such as copper on steel, at a joint.
5. Energiser, battery and earth. The energiser goes somewhere dry and ventilated, with its earth spikes close by and at least 10 m from any other earth system, and high-voltage cable to the fence.
6. Gates, keypad and alarm. Magnetic gate switches, the keypad, the siren and strobe, and the link to your alarm panel.
7. Signs and testing. Warning signs go up, and the alarm is tested with a short and a break at the furthest point of each zone, as Nemtek's notes ask.
8. Certificate and handover. You get the certificate and a walk-through: arming and disarming, the keypad codes, and what each alarm means.

Typical market prices for a new fence, installed, in Gauteng. They're not our prices, which are set in a quote after the site visit.

Cost guides agree: R95–R220 a metre (Kandua) installed in Johannesburg, and for a typical suburban home with 50 to 100 m of wall-top fence and its certificate, R12 000–R25 000 (Kandua). Short runs cost more per metre: R300–R400 a metre (ProCompare) all in. The energiser is the biggest single item: a Nemtek Druid 13 LCD is about R2 940–R3 280 (Takealot, NeonSales) in shops and a two-zone Nemtek Druid 25 LCD (2 zone) about R6 230 (NeonSales), with a 12 V 7 Ah battery R230–R450 (Takealot).

Prices checked October 2026. Your exact price is set in a free quote before any work starts. No call-out fee when we do the work. If no work is done, a R650 call-out fee applies.

Not every job starts from bare wall. We add lines to a low fence, extend a fence along a new wall, split a long single-zone fence into zones so faults are quicker to find, replace a tired energiser with a newer one, and add a keypad, gate switches or the link to an alarm panel. Adding to or altering a fence brings in a new certificate, so an extended fence is inspected again. A fence that keeps alarming may only need a repair: start with electric fence repairs.
