Electrical Compliance Testing & Certification
Powering the Nation, Safely
Reliable Electrical Compliance Testing and Certification
An installation can look fine and still fall short of the regulations. Testing and certification prove it is safe.
An electrical installation can look fine and still fall short of what the regulations require. Hidden wiring faults, ineffective earthing or protection devices that do not operate as intended cannot be judged by eye. Compliance testing and certification provide documented evidence that an installation has been inspected and tested against the applicable requirements, which matters to property owners, tenants, insurers and operators alike.
In South Africa, electrical installations are governed by regulations and standards, and a certificate of compliance is generally required for new work and for certain changes to existing installations. A specialised contractor tests the installation, records the results honestly and explains what any findings mean for the site.
National Electrical Services (NES) is a renowned electrical contractor in South Africa, operating in the electrical, construction and maintenance sector with offices in KwaZulu-Natal, Gauteng and the Western Cape. Its service offering includes compliance testing and certification, alongside new installations, maintenance, thermal imaging and fault finding. Organisations seeking a reliable electrical company in South Africa can contact NES to confirm the scope and availability of support for a specific site.
For businesses in Durban, Johannesburg, Cape Town and other parts of the country, the process starts with understanding the installation, defining what needs to be tested and making sure that the people carrying out the work are appropriately qualified.

Electrical Testing & Certification FAQs
Find answers to common questions about keeping your electrical installations safe and compliant.
How often should an electrical installation be tested?
Testing intervals depend on the property type, how it is used, and applicable regulations. We can review your installation and advise when its next inspection is due.
What certification do I need, and how should I prepare?
A certificate of compliance is generally required for new installations and for certain changes to existing ones. To prepare, have any previous certificates and drawings on hand, make sure distribution boards are accessible, and tell us about any known faults. We will confirm what applies to your site.
What happens if my installation fails an inspection?
We record the findings, explain what each one means and advise on the corrective work needed. Once the faults are fixed, we retest the installation and issue the certificate.
