Electric Fencing Installed and Repaired in South Africa

Electric fencing gives a short, safe but painful pulse to anyone who touches it and triggers an alarm when someone cuts or shorts the wires.

Electric fence installation

A typical electric fence installation includes:

  • An energiser that sends the pulse and monitors the fence
  • Brackets or posts with insulators, carrying several strands of wire
  • Earth spikes and an earth wire
  • A siren, keypad or link to your alarm system or armed response
  • A battery backup so the fence keeps working when the power is off

Every new or changed fence needs an Electric Fence System Certificate (EFC) from a registered electric fence installer, as required by the Electrical Machinery Regulations.

Price of electric fencing

The price of electric fencing depends on the length of the fence, the number of strands, the bracket type, the energiser size and the number of zones. Extra zones let you see which section was tripped. Battery backup, alarm integration, gate contacts and wall repairs add to the cost. Free-standing fences on farms and industrial sites need posts and more labour than wall-top fences. Long boundaries, corners and gates that need their own contacts all add time. Ask for a quote that lists the number of strands, the energiser, the battery backup and whether the EFC is included, so you can compare installers fairly.

Electric fencing repair and upgrades

Common electric fencing repair jobs are broken or slack wires, cracked insulators, plants touching the strands, failed batteries and energisers damaged by lightning or power surges. An installer can test the fence, find faults and bring an old fence up to standard so it can be certified. If you are searching for electric fence installation near me, a local installer can also advise on keeping the fence clear of trees and neighbours' walls. Regular checks, trimming plants and replacing the battery every few years keep false alarms down.

How to compare electric fencing quotes

The cheapest price per metre is not always the best value in fencing. When your electric fencing quote arrives, check:

  • Materials: the wire or steel thickness, the type of galvanising or coating, and the pole size and spacing. Thinner material looks the same on day one but fails sooner.
  • Foundations: how deep the poles are set and whether they are concreted. Most fence failures start at the posts.
  • What is included: gates, locks, corner stays, removal of an old fence, site clearing and rubble removal.
  • Guarantee and timing: workmanship guarantees, the expected start date and how long installation will take.

Our service passes your request to a contractor who works in your area, so you can ask these questions before you commit. It costs nothing and you are under no obligation to accept the quote.

Request a electric fencing quote

To get an accurate quote quickly, include:

  • The total length of wall or fence in metres
  • The number of strands and whether it goes on a wall or free-standing
  • Whether you need battery backup and a link to your alarm or armed response
  • The number of zones and gates
  • Whether it is a new fence, an upgrade or a repair

Photos or a rough sketch of the boundary help too. Mention them in the details and the contractor will ask for them.

Frequently asked questions

Do I need a certificate for my electric fence?

Yes. New fences, and fences that are changed, need an Electric Fence System Certificate (EFC) from a registered installer. You may also need one when you sell your property.

Does an electric fence work during load shedding?

Yes, if the energiser has a working backup battery. Ask your installer about battery size and how long the fence will run without mains power.
