Expert Electrical Rewiring in Centurion
Older properties in Centurion and Pretoria often have deteriorated electrical wiring that poses a serious fire risk — brittle insulation, undersized conductors, aluminium wiring, or non-compliant routing. Electrician Centurion carries out full and partial rewiring projects using quality PVC-insulated copper cable, neatly routed and fully compliant with SANS 10142-1.
We work methodically to minimise disruption — planning the rewire carefully so your home remains liveable throughout the project. Cable routes are planned for neatness and compliance, conduit is correctly installed, and all new wiring is tested and documented before we issue your Certificate of Compliance.
Why Choose Electrician Centurion for Rewiring
SANS-Compliant Copper Wiring
We use only quality SANS-approved PVC-insulated copper conductors — correctly sized for each circuit, providing safe, reliable, and code-compliant wiring throughout.
Minimal Disruption Approach
We plan the rewire carefully to keep your home functional throughout the project, working room by room and restoring power progressively.
Aluminium Wire Replacement
Aluminium wiring common in properties built in the 1970s–1990s is a known fire hazard. We replace it entirely with modern copper — making your home safe and insurable.
Full COC on Completion
Every rewiring project concludes with comprehensive circuit testing and a valid Electrical Certificate of Compliance — essential for insurance and property transfer.
Signs Your Property Needs Rewiring
-
Brittle or Cracked Insulation Old wiring with cracked, brittle, or discoloured insulation is a serious fire risk — bare conductors can arc against each other or combustible surfaces at any time.
-
Aluminium Wiring Properties built before 2000 in South Africa may have aluminium wiring — which expands and contracts differently to copper connections, causing dangerous loose joints over time.
-
Frequent Electrical Faults If you have recurring breaker trips, flickering lights, or dead circuits across multiple areas, your wiring may be too deteriorated for targeted repairs — a full rewire is safer and more economical.
-
Non-Compliant Wiring Routes DIY or old wiring routed incorrectly — through wall cavities without conduit, undersized for the load, or unprotected in accessible areas — must be replaced to be compliant and safe.
-
Failed COC Inspection If your property has failed an electrical inspection for transfer or insurance purposes, rewiring the non-compliant sections is the correct remedy.

Frequently Asked Questions — Rewiring
How do I know if my house needs rewiring?
Key signs are recurring electrical faults, brittle or discoloured cable insulation, aluminium wiring, a property over 30 years old that's never been rewired, or a recently failed electrical inspection. We offer a free assessment — call 078 912 0847.
How long does a full house rewire take?
A typical 3-bedroom house takes 3–7 days depending on complexity, access, and how much of the existing wiring can be reused. We provide a schedule with your quote.
Do I have to leave my house during a rewire?
Not necessarily. We work room by room and maintain power to unaffected areas throughout the project. Some days require a full power outage of a few hours — we plan these to minimise inconvenience.
Is aluminium wiring dangerous?
Yes — aluminium wiring is a recognised fire hazard. It oxidises at connection points, creating high resistance joints that overheat. Many South African insurers will not cover properties with aluminium wiring. Replacement with copper is essential.
What cable do you use for rewiring?
We use only quality SANS 1507-approved PVC-insulated copper conductors in the correct cross-sectional area for each circuit — 1.5mm² for lighting and 2.5mm² for plug circuits as a minimum, with larger sizes for high-load circuits.
