If your Sydney home is showing signs of outdated or deteriorating wiring — flickering lights, tripping safety switches, warm powerpoints, or a switchboard still running ceramic fuses — it’s time for a professional house rewiring assessment. Moonlight Electrical provides full and partial house rewiring across Sydney, replacing old cabling with modern, compliant wiring that meets current AS/NZS 3000 standards. As licensed and Level 2 ASP accredited electricians based in Western Sydney, we handle everything from the initial inspection through to final testing, certification, and compliance documentation — all quoted upfront per job so you know the cost before any work begins.
Why Sydney Homes Need Rewiring
Sydney’s housing stock includes a significant number of homes built before modern wiring standards were introduced. Properties across Western Sydney suburbs like Merrylands, Greystanes, Parramatta, and Toongabbie often still have their original wiring from the 1950s through 1980s — including VIR (vulcanised India rubber) and TPS cabling that has degraded with age. Even homes from the 1990s can have wiring that no longer meets the demands of modern households, particularly with the addition of air conditioning systems, home offices, electric vehicle chargers, and high-draw kitchen appliances.
Degraded wiring doesn’t just cause inconvenient power issues — it’s a genuine safety risk. Old wiring with deteriorating insulation can overheat, arc, and in the worst cases cause electrical fires. Outdated switchboards without safety switches (RCDs) provide no protection against electrocution. A professional rewire brings your home up to current AS/NZS 3000 Wiring Rules, eliminates these risks, and gives your electrical system the capacity to handle your household’s actual power requirements.

Frequently Asked Questions
How long does it take to rewire a house?
Most full house rewires take between 3 and 7 days depending on the size of the home and complexity of the work. A 3-bedroom single-storey home typically takes 3–4 days. Larger homes, double-storey properties, or homes with limited cavity access may take a week or slightly longer. We’ll give you an estimated timeframe with your quote.
Can I stay in my house during the rewire?
In most cases, yes. We work room by room and plan the power interruptions to minimise disruption to your daily routine. You may lose power to specific areas during the working day, but we keep the impact as contained as possible. We’ll provide a schedule so you know what to expect each day.
Do I need council approval to rewire my house in Sydney?
Generally, no. Rewiring falls under general electrical maintenance and does not require development approval. However, if your property is heritage-listed or in a conservation area, you may need to check with your local council before any work that involves opening walls or ceilings. All electrical work requires a licensed electrician, and we issue a CCEW (Certificate of Compliance Electrical Work) upon completion as required by NSW law.
Will rewiring damage my walls and ceilings?
Some access to wall and ceiling cavities is necessary, but modern rewiring techniques minimise the disruption. In many homes, we can fish new cabling through existing cavities without major damage. Where access holes are required, they’re kept as small as possible. We always discuss the likely impact during the assessment so you know what to expect before any work starts. Patching and making good is typically arranged separately with a plasterer.
How do I know if my home needs a full rewire or just repairs?
The honest answer is that it depends on what we find during the inspection. If the wiring issues are isolated to a specific area — a single room, a kitchen circuit, or one section of degraded cabling — a partial rewire or targeted repair may be sufficient. If the wiring throughout the house is the same age and showing signs of deterioration, a full rewire is usually the more cost-effective and safer long-term solution. We’ll always give you an honest assessment of both options.
Is rewiring worth it for an older home?
Absolutely. Rewiring an older Sydney home eliminates the fire and electrocution risks associated with degraded wiring, brings your property into compliance with current standards, supports the electrical demands of modern appliances and devices, and can improve your home’s resale value. Insurance companies also take a close look at the condition of electrical systems, and outdated wiring can affect your coverage.
Is it better to vent a rangehood through the wall or roof?
Wall venting is generally preferred because it’s a shorter, more direct ducting run which means better airflow and easier installation. Roof venting is necessary when the cooktop is on an internal wall with no practical path to an external wall. Longer ducting runs and bends reduce extraction efficiency, so we always aim for the shortest route with the fewest turns. We’ll assess your kitchen layout and recommend the best option during the initial inspection.
