In short: an electric fence sends short, high-voltage pulses along tensioned wires. Anyone touching it gets a sharp shock that is meant to deter, not injure, and the siren sounds if the wires are cut or shorted. In Kenya the usual setup is a wall-top fence on brackets above a compound wall; farms and large plots use free-standing fences. It only works properly with the right energizer, good earthing and correct wire tension.
Wall-top or free-standing?
| Type | Where it suits | How it is built |
|---|---|---|
| Wall-top | Homes and businesses with an existing compound wall | Steel brackets bolted along the top of the wall carry several strands of wire above it, so the fence adds height as well as a shock. |
| Free-standing | Farms, large plots, sites with no wall | Strainer posts at corners and gates, support posts along the run, and more strands from near the ground upwards. |
What goes into an electric fence
- Energizer: the unit that sends controlled pulses along the fence, sized to the length of fence.
- High-tensile wire or tape: strung at the right spacing and tension so it cannot be pushed apart.
- Insulators, brackets and posts: strainer posts at corners and gates, W-posts or support posts along the run.
- Siren alarm kit: sounds when the fence is cut, shorted or tampered with.
- Earthing: several earth spikes driven deep into the ground. Without good earthing the fence gives a weak shock.
- Warning signs: fixed at regular intervals and at every gate.
Every one of these parts is listed with its price in our shop’s electric fencing section.
Power cuts
An energizer with a backup battery keeps the fence live and the alarm armed through KPLC outages. We recommend it for any fence that protects a home at night.
How we install it
We walk and measure the perimeter, recommend wall-top brackets or a free-standing fence, and list every material and the labour in the quote. On installation day we fix the brackets or posts, string and tension the wire, connect the energizer and alarm, earth the system, put up the signs and test the voltage along the fence before handover.
Better together
An electric fence tells you someone tried to get in; CCTV shows you who. Add an automatic gate so you never have to get out of the car at the gate after dark.

Questions about electric fencing
How much does electric fence installation cost in Kenya?
It is priced per metre and depends on wall-top or free-standing, the number of strands, the energizer and the number of corners and gates. We measure the perimeter for a free quote; the materials are priced in our online shop.
Is an electric fence safe for children and pets?
A properly installed fence uses an energizer that sends short, controlled pulses rather than continuous current, so it gives a sharp shock that is meant to deter, not injure. Warning signs along the fence are essential.
Does an electric fence work during a power cut?
Yes, if the energizer has a backup battery. We recommend battery backup for any fence that protects a home or business at night.
Can you put an electric fence on top of my existing wall?
Yes. Wall-top brackets carry the wires above an existing compound wall, so there is no need to build a separate fence.
Will the alarm go off if the fence is cut?
Yes. A siren alarm kit sounds when the fence is cut, shorted or tampered with.
