SANS 10222-3 Decoded: What the New 2023 Standard Means for Installers and Homeowners

Introduction

Electric fencing has become a common security feature in South African homes, businesses, and farms. As crime rates rise and safety concerns grow, more property owners are turning to electric fences to deter intruders. But electric fences are not just a matter of installation and deterrence—they are tightly regulated to ensure safety, reliability, and compliance with the law.

The South African Bureau of Standards (SABS) recently released an updated version of the national electric fence regulations: SANS 10222-3:2023 (Edition 5.1). This new standard introduces several important changes that affect both professional installers and everyday homeowners.

Understanding these updates is crucial. For installers, compliance is not optional—non-adherence can lead to legal consequences and loss of accreditation. For homeowners, knowing the requirements protects against liability, ensures insurance validity, and guarantees safety for residents and visitors.

This article breaks down the new 2023 standard in plain language. We’ll explain what has changed, why it matters, and what both installers and property owners must do to stay compliant.

1. Scope and Applicability of the 2023 Revision

The updated SANS 10222-3:2023 sets out the requirements for the design, installation, and maintenance of non-lethal electric fence systems.

What types of fences are covered?

The standard applies to electric fences used for:

Residential security: protecting homes, complexes, and estates.
Animal control: strip grazing systems and pet enclosures.
Game and wildlife management: containing or protecting wild animals.
Commercial and industrial security systems.

Why is this important?

Because the law requires all electric fences installed after October 2012 to comply with SANS standards, this update affects:

Installers who must issue certificates of compliance (COCs).
Homeowners who want to transfer property or maintain valid insurance.

2. Legal and Compliance Imperatives

Electric fencing is not just a technical installation—it is a regulated security system.

The Electric Fence Certificate of Compliance (EFS COC)

Every new installation must have a valid certificate issued by a registered Electric Fence System Installer (EFSI).

A COC is required when:

The property changes ownership.
Major alterations are made to the fence.
Requested by an inspector or legal authority.

Does the certificate expire?

No, certificates do not have a fixed expiry date. However, a new one may be needed if:

The energiser is replaced.
The layout or structure of the fence changes significantly.
Additional fencing is added.

Consequences of non-compliance

Home sales can be blocked.
Insurance claims may be rejected.
Homeowners may face legal liability in case of injury.

3. Enhanced Warning Signage Requirements

One of the most visible changes in the 2023 update concerns signage.

Where signs must be placed

At intervals of no more than 10 metres in urban areas.
At every pedestrian and vehicle gate.
At property corners or other entry points.

What the signs must display

A clear lightning bolt symbol.
A warning in at least two official South African languages.
Highly visible colours, typically yellow and black.

Why signage matters

Warning signs are not cosmetic—they are legal safeguards. They protect homeowners against liability claims and ensure visitors, workers, and even trespassers are aware of potential danger.

4. Grounding, Earthing and Electromagnetic Safety

A major update in the 2023 edition concerns earthing requirements.

Key rules on grounding

All cables connecting the fence to earth spikes must run in conduit.
Cables must remain accessible for inspection.
Grounding cables may not be buried directly in the soil.

Why earthing is critical

Proper earthing prevents:

Shock hazards in case of electrical faults.
Electromagnetic interference with nearby communication lines.
Reduced fence effectiveness during bad weather.

For installers, this means stricter inspection requirements and a higher level of workmanship.

5. Material Quality and Weather Resistance

Another shift in the new standard is a stronger focus on material durability.

New expectations for components

Insulators must withstand long-term weather exposure.
Wires must meet minimum grade and tensile strength requirements.
All connectors and joints must resist corrosion.

Benefits for homeowners

Lower long-term maintenance costs.
Better fence reliability during storms.
Fewer premature replacements.

While higher-grade materials may raise installation costs slightly, they improve long-term performance and safety.

6. Testing, Inspection and Maintenance Protocols

The 2023 revision places greater emphasis on regular inspection and testing.

Minimum inspection schedule

Monthly visual checks: look for broken wires, leaning poles, or damaged insulators.
Quarterly testing: confirm voltage output, earth resistance, and energiser functionality.
Annual professional servicing: conducted by a registered installer.

Why this matters

Consistent inspections:

Extend fence lifespan.
Prevent costly failures.
Ensure compliance in the event of an insurance claim or property transfer.

For homeowners, scheduling regular maintenance is no longer optional—it’s an essential part of compliance.

7. Intersection with Occupational Health and Safety Legislation

Electric fencing does not exist in isolation—it ties into broader Occupational Health and Safety (OHS) regulations.

Energiser compliance

All energisers must:

Meet the IEC 60335-2-76 standard.
Have a valid Letter of Authority (LOA) issued by the National Regulator for Compulsory Specifications (NRCS).

Why this matters

Non-compliant energisers may be illegal to operate.
Using uncertified equipment could void insurance cover.
Installers risk losing their registration if caught using unauthorised products.

This clause ensures that every component of an electric fence meets internationally recognised safety standards.

8. Installer Obligations and Registration

The standard introduces new professional expectations for installers.

Who can issue certificates?

Only a registered Electric Fence System Installer may issue a COC. Installers must:

Complete recognised training.
Pass competency assessments.
Be listed in the national installer database.

Responsibilities of installers

Educate clients about compliance requirements.
Use only approved components.
Maintain accurate installation records.

For homeowners, this means always verifying that your installer is accredited before work begins.

9. Implications for Homeowners

Homeowners often assume compliance is the installer’s problem. The new standard makes it clear: property owners share responsibility.

What homeowners must do

Ensure they receive and keep a valid certificate of compliance.
Schedule regular inspections and maintenance.
Use only registered installers for repairs or modifications.

Risks of ignoring compliance

Legal liability: if a person or animal is injured, the owner may be held responsible.
Insurance issues: non-compliant fences may invalidate cover.
Property transfer delays: selling a house without a valid certificate is not possible.

Compliance is not just a legal formality—it protects families, visitors, and property value.

10. What Installers Need to Act On Now

The 2023 standard is already in effect, which means installers must adapt immediately.

Action points for installers

Study the new edition of SANS 10222-3 in full.
Upgrade materials and methods to align with new requirements.
Adopt stricter signage placement—especially at gates and corners.
Implement documented maintenance checks for every client.
Verify accreditation regularly to remain on the national register.

By following these steps, installers can protect their professional reputation while ensuring client safety and compliance.

FAQs on SANS 10222-3:2023

Do all electric fences need a compliance certificate?

Yes, every electric fence installed after October 2012 requires a certificate issued by a registered installer.

How often should an electric fence be inspected?

At minimum, monthly visual checks and quarterly voltage/earth resistance tests are required.

Can I sell my home without an electric fence certificate?

No. The property transfer process requires a valid certificate before ownership can change.
