House Rewiring Electrician Sydney
Old wiring doesn't announce itself until something goes wrong a breaker that trips for no obvious reason, a power point that's warm to the touch, or a builder pulling back a wall to find rubber-sheathed cable that should have been replaced decades ago. Beattie Electrical works through these jobs the way most Sydney homes actually need them handled: methodically, with minimal mess, and with every circuit tested and certified before we call the job finished.
Benefits of Rewiring Your Home
Removes a genuine fire and shock hazard hidden inside walls and roof spaces
Restores full circuit capacity for the appliances a modern household actually runs
Gives you a documented compliance record that supports insurance claims and resale
Cuts down on nuisance trips, blown fuses and flickering lights
Leaves you with a clearly labelled, modern switchboard instead of a mystery fuse box

Signs Your Sydney Home May Need Rewiring
Types of Rewiring We Carry Out
Full House Rewiring
We replace wiring circuit by circuit throughout the property, fit a new switchboard sized to the home's actual load, and lodge a Certificate of Compliance for Electrical Work once every circuit has been tested.
Partial House Rewiring
Not every home needs the whole property opened up. Where only certain rooms or circuits have deteriorated, we isolate and replace just those runs, leaving the rest of the house powered, tested and undisturbed for the duration of the job.
Heritage Home Rewires
Federation cottages, Californian bungalows and inter-war homes across Sydney often still carry vulcanised rubber or cloth-insulated cable behind original cornices, picture rails and skirtings. We trace these runs carefully and plan access points that protect period detailing wherever the job allows.
Switchboard Rewire and Upgrade
A rewire is usually the moment to deal with an ageing switchboard too swapping ceramic fuses and undersized boards for a modern unit fitted with circuit breakers, RCD safety switches, and circuits labelled clearly enough that the next electrician (or the homeowner) can actually make sense of them.
Pre-Renovation Rewiring
Getting the wiring sorted before a kitchen, bathroom or extension gets closed in avoids paying twice for wall access later,
Post-Purchase Rewiring
When a building and pest inspection flags old wiring before settlement, we scope the rewire against that report so new owners can plan the work and the budget
Asbestos Switchboard Replacement
We coordinate licensed asbestos removal alongside the rewire so the hazard is dealt with properly rather than built over and left for the next owner to find.
Cable Upgrade for Modern Loads
Cable sized for a 1960s household of lamps and a fridge often can't safely carry an induction cooktop, ducted air conditioning, an EV charger and a home battery running together. We upsize the circuits that matter most before those loads get added, rather than after something trips.
Sub-Circuit Replacement
Where only a single circuit has failed a scorched connection at the sub-board, or a run that tripped testing during a sale we replace that circuit alone, leaving the rest of the property's wiring untouched if it's still testing sound on inspection.
Three-Phase Conversion
Bigger loads, home workshops, and some EV charger or solar-plus-battery setups call for three-phase power. We manage that upgrade alongside the network provider, coordinating the new service cable, meter and switchboard work as one project rather than three separate headaches.
Strata Common-Area Rewiring
Strata buildings scheduling common-area rewires for stairwells, basement car parks, plant rooms and shared risers need work coordinated through the strata manager, sequenced around resident access, and reported back to the committee with a clear scope and sign-off at every stage.
Our Rewiring Process
we walk the property, check switchboard condition, and identify accessible and difficult cable runs
scope, staging and an estimated timeframe confirmed before any work is booked
new cable pulled through walls, roof and subfloor cavities with minimal reinstatement work
powerpoints, switches, light fittings and the switchboard connected and clearly labelled
insulation resistance, RCD trip time and earth fault loop impedance checked on every circuit
lodged and handed over, with the property ready for reinstatement trades if needed
Common Problems We Find During Rewires
Wiring joined by different owners across decades, creating mixed-era connections that were never designed to work together
Undersized original cable now feeding modern high-draw appliances it was never rated for
Corroded or previously DIY-repaired connections hidden behind walls and ceilings
Additions from earlier renovations that were never brought up to current standard
Preventative Electrical Maintenance Advice
Book a periodic electrical safety inspection, particularly for homes over 20 years old
Test safety switches at the switchboard every few months using the built-in test button
Keep an eye on the switchboard for warmth, discolouration or a burning smell
Deal with single-circuit issues promptly, rather than letting them compound into a full rewire
Australian Compliance Requirements
- All rewiring work must meet the AS/NZS 3000 wiring rules (the Australian/New Zealand Standard for electrical installations)
- Only a licensed electrician can legally carry out switchboard and circuit wiring work in NSW
- A Certificate of Compliance for Electrical Work (CCEW) is lodged after testing confirms the installation meets standard
- Modern circuits must be protected by RCD safety switches, not just circuit breakers alone
- Asbestos-containing switchboard components must be handled and disposed of through licensed asbestos removal, not general demolition
Rewiring Options by Scope Disruption and Fit
| Rewire Type | Typical Scope | Disruption Level | Best Suited To |
|---|---|---|---|
| Full House Rewire | Every circuit, powerpoint, switch and light circuit replaced, plus new switchboard | High — staged over multiple days, most rooms affected in turn | Homes built before 1980 with widespread original cabling still in use |
| Partial Rewire | Selected rooms or circuits only; rest of the property stays live | Low to moderate — contained to the affected zone | Homes with one ageing section (e.g. an original wing) but sound wiring elsewhere |
| Sub-Circuit Replacement | A single damaged or non-compliant circuit | Low — usually a single-day job | A specific fault or defect flagged on inspection, rest of the home compliant |
| Switchboard Upgrade Alone | Switchboard and main protective devices, not the branch cabling | Low — typically half a day to a day, power off briefly | Homes with sound cabling but an outdated fuse-wire or undersized board |
Warning Signs, Likely Cause and Recommended Action
| Warning Sign | Likely Cause | Recommended Action |
|---|---|---|
| Lights flicker or dim when an appliance starts | Loose connection or a circuit carrying more load than it was designed for | Book a fault-finding visit; may point to a partial rewire of that circuit |
| Power point feels warm or has a discoloured faceplate | Failing internal wiring or a loose termination behind the point | Stop using it and arrange an inspection promptly |
| Breakers or fuses trip repeatedly | Overloaded or degraded circuit no longer handling its rated load safely | Circuit-by-circuit assessment to isolate the affected run |
| Burning smell near the switchboard or a power point | Overheating wiring, connection or fuse — treat as urgent | Turn off power to the area if safe to do so and call an electrician immediately |
| Fabric or rubber-coated cable visible in the roof or subfloor | Original pre-1980s wiring nearing or past its safe service life | Schedule a full rewiring assessment before further deterioration |
| Building/pest inspection report flags old wiring | Ageing cable or switchboard identified during a property transaction | Get a written scope and quote before or shortly after settlement |
