Have you ever been told that your Sydney home needs to be re-wired? In many cases, this is because cotton cloth wiring, also known as VIR (Vulcanised Indian Rubber) cable, has been discovered in the property. This outdated wiring type is unsafe, deteriorates over time, and must be replaced immediately to meet modern electrical safety standards. We’ve created a comprehensive guide on electrical wiring, including what to do if you find cotton cloth wiring or VIR wiring in your home. At True Local Electricians, we specialise in residential electrical wiring and full house re-wiring, replacing hazardous cabling with modern, safe TPS cable. We offer free, no-obligation quotes and can upgrade your home’s wiring to keep your property compliant, efficient, and safe for years to come.
Cotton cloth wiring is exactly how the name sounds. The cable has a copper conductor which is wrapped in cotton like sheathing which protects the metal conductor from contacting external things.

Cotton cloth wiring and VIR (Vulcanised Indian Rubber) cable were once standard in Australian homes and commercial buildings built prior to the 1980s. VIR wiring typically appears as black rubber-insulated cable that becomes brittle, cracked, and rigid over time. Cotton cloth wiring often has a woven outer sheath that frays as it ages. In many cases, these cables are also connected to old-style fuse boxes, outdated switchboards, or non-compliant meter boxes. You should never touch deteriorating cotton cloth wiring, as it can crumble easily and create an immediate shock or fire hazard.
While cotton cloth wiring and VIR wiring were considered safe when installed decades ago, they no longer meet today’s Australian electrical safety standards. The outer insulation breaks down with heat, age, and rodent activity, exposing the bare conductor. This can lead to contact with metal conduits, plumbing pipework, or switchboard enclosures, increasing the risk of arcing, fires, or electric shock severe enough to cause injury or death. We often discover cotton cloth wiring when carrying out switchboard upgrades, meter box replacements, or during defect repairs issued by Ausgrid or Endeavour Energy. Replacing these cables as part of a full re-wire ensures your system is safe and compliant.
Yes - cotton cloth wiring and VIR cable should be replaced immediately once identified. Leaving them in place increases the risk of electrical faults, insulation breakdown, and non-compliance with NSW Service & Installation Rules. If you have received a Level 2 defect notice for unsafe wiring, our licensed electricians can inspect your property, replace all outdated cabling, and upgrade your residential or commercial switchboard and meter box to current standards.
We replace outdated cotton cloth wiring and VIR cable with modern TPS (Thermoplastic-Sheathed) cable, the current industry standard in Australia. TPS cable is durable, heat-resistant, and long-lasting, making it a safe, compliant wiring solution. Where necessary, we also carry out a full switchboard upgrade, replace your meter box, and ensure RCD safety switches are installed for maximum protection.
The cost of rewiring a property with cotton cloth wiring depends on the size, layout, and accessibility of your home or business. Generally for a full home electrical re-wire by True Local Electricians you should budget for up to $15,000. Our full home re-wire service involves removing old wiring and installing new cabling to every power point, light fitting, and switch, along with updating switchboards and meter boxes. This complex process must be performed by a licensed electrician to meet Australian Standards and network provider requirements. We provide free, no-obligation quotes so you know exactly what’s involved before we begin.
