Old or deteriorated cable
Brittle rubber, fabric-covered conductors or damaged insulation found at fittings can indicate wider deterioration. Accessible samples and test results help establish whether replacement should be local or broader.

Home Rewiring in Sutherland Shire & St George
Home rewiring is considered when cable insulation has deteriorated, circuits no longer support modern use, an older property is being opened for renovation, or testing reveals defects spread across the installation. It may involve the entire home or a defined area such as an original rear section, kitchen or extension.

01 / Signs You Need This
When to arrange home rewiring.
Age alone does not prove a home needs a full rewire, but these observations justify an electrical assessment and testing.
Rewireable fuses and limited protection
An old fuse board can signal that circuits predate modern safety arrangements. The board, earthing and cable condition need to be assessed together rather than upgrading one component in isolation.
Too few circuits and outlets
Heavy reliance on adaptors and extension leads often reflects a layout designed for a different era. A rewire can separate major loads and place outlets where they are actually needed.
Recurring faults in several areas
Multiple issues across unrelated rooms may point to ageing cabling, poor historic alterations or connections that require more than isolated accessory replacement.
Walls are opening for renovation
A renovation provides practical access to replace wiring and add circuits before new plaster, joinery and finishes are installed. Planning early reduces later cutting and rework.
No clear record of alterations
Homes extended in stages may have mixed cable, unclear junctions and incomplete labels. An inspection establishes what is present before a safe replacement scope is prepared.
02 / What's Included
A considered scope, based on the property.
The scope is tailored to the condition of the installation and the building program, not treated as a simple cable-for-cable exchange.
Existing installation survey
We identify circuits, protective devices, accessible cable types, earthing and likely routes. Findings determine whether a full rewire or targeted replacement is justified.
Circuit and outlet planning
Lighting, general power and fixed appliances are planned around room use, expected loads and furniture or joinery layouts, with allowance for future needs discussed during design.
New cabling and accessories
Approved cable, switches, outlets and connection equipment are installed using practical routes through roof, wall or subfloor spaces while limiting unnecessary disturbance.
Switchboard integration
New circuits require suitable circuit breakers and RCD protection. Any switchboard work is scoped from the existing board condition and available capacity.
Staged rough-in and fit-off
For renovations, cabling is installed before linings close, then fittings are connected after finishes and joinery are ready. Occupied-home projects can be divided into agreed stages.
Testing, labels and CCEW
Circuits are verified, labelled and tested before energisation. Required CCEW documentation is completed and circuit information is handed over at completion.
03 / How the Job Works
From the first conversation to certification.
A rewire is managed as a small project, with decisions and access agreed before walls or circuits are disturbed.
Inspection and priorities
We inspect the board and representative points, discuss known faults and record renovation plans, critical equipment and areas that must remain available.
Define full or partial scope
Test results, cable condition and access are used to identify what must be replaced and what can remain. Exclusions and assumptions are written into the quote.
Plan routes and staging
We map circuits, switch and outlet positions, access points, shutdowns and coordination with plasterers, carpenters or cabinetmakers.
Isolate and rough in
Old sections are safely disconnected and new cable is installed in stages. Temporary arrangements are discussed where the home remains occupied.
Fit off and identify circuits
Switches, outlets, lights, appliances and protective devices are connected, with the board schedule updated to reflect the finished installation.
Test and certify
Mandatory electrical tests are completed before handover. Required defects are addressed, a CCEW is issued and operating information is provided.
04 / Safety & Compliance
Electrical work completed properly in NSW.
Rewiring is licensed electrical work and must comply with NSW law and applicable requirements of AS/NZS 3000. New and altered circuits are tested before energisation and documented through the CCEW process where required.
Network-side changes are not performed as ordinary rewiring. If supply capacity or distributor equipment needs alteration, we coordinate that component with an accredited Level 2 partner.
05 / Exclusions & Limitations
What the service does not automatically include.
Clarifying related building tasks protects the program and avoids uncertainty about who restores finishes after electrical access.
Separate trade work
Plastering, painting, tiling, joinery removal and other making-good are separate unless expressly included.
Finishes and making good
Asbestos or other hazardous-material testing and removal require qualified specialists.
Specialist approvals
Supply authority and network-side alterations are coordinated separately with accredited Level 2 partners.
Unrelated defects
Temporary accommodation, furniture storage and owner contents handling are not included.
Additional equipment
Data, security, solar and automation systems are separate scopes unless shown in the accepted quote.
06 / Local Knowledge
Sutherland Shire and St George homes are not all wired alike.
Post-war brick veneer homes in Kirrawee, Sutherland, Gymea and Miranda may offer roof and subfloor routes, but renovated sections often contain concealed junctions from earlier work. Surveying each section avoids assuming the whole property was wired at once.
Solid masonry and older decorative interiors in parts of St George require careful route planning. Existing conduits may be reusable only after inspection, while some locations need surface solutions or coordinated wall access.
Duplexes and townhouses can limit access between levels and may involve shared walls or strata approvals. The scope should identify lot property, common property and approved working hours before work begins.
On renovation projects, early coordination with demolition and framing is usually the most efficient approach. Our suburb pages for Kirrawee, Sutherland, Gymea, Miranda, Caringbah, Cronulla, Sylvania and Taren Point provide more local detail.

08 / Frequently Asked Questions
Home rewiring questions, answered.
Does an old home always need a full rewire?
No. Inspection and electrical testing are needed to determine cable condition and whether defects are isolated or widespread. A partial scope may be appropriate in some homes.
Can we stay in the home during rewiring?
Sometimes, depending on the scope and safe separation of work areas. We discuss staged shutdowns, essential power and practical disruption before confirming the program.
Will walls need to be opened?
Some access may be required, especially in solid masonry or inaccessible multi-storey areas. Existing roof and subfloor access is used where practical, and making-good responsibilities are identified in advance.
Is a switchboard upgrade always included?
The board must be suitable for the new circuits and current protection requirements. Whether it needs full replacement or specific changes depends on its inspected condition and capacity.
When should rewiring happen during a renovation?
Planning should begin before demolition. Rough-in occurs while framing and cavities are accessible, with fit-off after linings, cabinetry and finishes are ready.
What documentation is supplied?
Required CCEW documentation and an updated circuit schedule are supplied for completed electrical work. Product information is also handed over where relevant.
