Here’s the Quick Answer
As a general 2026 guide, a full house rewire in Sydney will often sit somewhere between $8,000 and $18,000+ for many standard homes, depending on access, property size, wiring condition and the number of circuits required. Smaller units may start from around $3,500-$7,500, while larger homes, double-storey properties, terraces or heritage homes can move into the $15,000-$26,000+ range. Extra work such as switchboard upgrades, consumer mains, smoke alarms, new lighting, data points or additional power points can increase the final cost.

Sydney House Rewiring Cost Guide for 2026
The prices below are general guide ranges for Sydney homes and should not be treated as a fixed quote. The final cost depends on the property, access, existing wiring, switchboard condition, compliance requirements and the exact scope of work. Fox Electricians can inspect the property and provide a written quote based on what is actually required.
Typical full rewire (house): $8,000-$18,000+ incl. labour and materials
Units (1–2 bed): $3,500–$7,500
Small to mid-sized houses (2-3 bed, single storey): $8,000-$15,000
Larger or double-storey homes (4+ bed): $15,000-$25,000+
Terrace or heritage homes: $18,000-$35,000+
Partial rewire (kitchen + wet areas): $2,000–$6,000
Timeframe: 2–6 days for most homes. Staged or complex jobs can run 1–2 weeks.
Includes: compliant cabling, RCD/RCBO protection to current Wiring Rules, labelled circuits, full testing, and a CCEW issued and submitted as required.
May add to cost: switchboard upgrade ($1,200–$3,000), consumer mains upgrade by a Level 2 ASP ($2,000–$5,000), extra outlets and lighting.
Rewiring Price Table: By Home Type and Size
| Home type | Estimated range (incl. GST) | Days on site | Notes |
|---|---|---|---|
| 1–2 bed unit | $3,500–$7,500 | 2–4 | Usually simpler access from ceilings. Strata rules may limit work hours. |
| 2–3 bed house, single storey | $7,000–$12,000 | 3–5 | Common scope. Insulation or tight roof spaces add time. |
| 4+ bed house or double-storey | $12,000–$22,000 | 5–8 | More circuits and cable runs. Extra time for subfloor work. |
| Terrace or heritage home | $14,000–$26,000 | 5–9 | Lath-and-plaster, double brick, heritage constraints increase labour. |
| Partial rewire (kitchen + wet areas) | $2,000–$6,000 | 1–2 | Good interim step when staging a full rewire. |
| Switchboard upgrade (if required) | $1,200–$3,000 | 0.5–1 | Adds modern RCDs and clear labelling. Asbestos panel replacement if needed. |
| Consumer mains upgrade (if required) | $2,000–$5,000 | 0.5–1 | Level 2 ASP. Needed for added load or undersized mains. |
For some NSW residential building work over $20,000 including GST, Home Building Compensation insurance may be required unless an exemption applies. If your rewiring project is likely to exceed this threshold, Fox Electricians can advise what applies to the agreed scope of work before the job proceeds.
What Affects House Rewiring Cost in Sydney?
In Sydney, rewiring costs can vary significantly because homes are built in many different styles and conditions. Older terraces, double brick homes, apartments, strata properties, renovated homes and larger family houses can all require different levels of access, planning and electrical work. The more difficult it is to access roof spaces, walls, subfloors or existing cable routes, the more time may be needed on site.
Home size and circuit count – more rooms and circuits mean more cable and time.
Access – roof space, subfloor, insulation, double brick, and wall type (plasterboard vs lath-and-plaster).
Occupied vs vacant – empty homes are faster and cheaper to work in.
Switchboard condition – old ceramic fuses or missing RCD safety switches usually mean an upgrade.
Earthing and mains – undersized or damaged supply may require a consumer mains upgrade by a Level 2 ASP.
Extras – new powerpoints, lighting, data points, and smoke alarms added during the job.

What Is Included In a Full Rewire
New TPS cabling installed to AS/NZS 3000 standards
Circuit design and clear labelling at the switchboard
RCD/RCBO protection for final sub-circuits in line with current Wiring Rules
Removal or bypass of old VIR/TRS cable and ceramic fuses
Comprehensive testing and a Certificate of Compliance for Electrical Work (CCEW) issued and submitted as required
Site clean-up and handover
Do I Need a Switchboard or Mains Upgrade?
You likely need an upgrade if you have:
Ceramic fuses or no RCDs
Overheating, scorching or brittle fuse carriers
Older meter panels may contain asbestos (e.g. Lebah, Miscolite, Zelemite brands) and often require safe replacement.
Added load from new appliances, EV charging or air-con
A switchboard upgrade brings the installation into line with current Wiring Rules (AS/NZS 3000), including updated protective devices and clear labelling. A consumer mains upgrade is done by a Level 2 ASP where capacity or condition is an issue.
Signs Your Home May Need Rewiring
Frequent tripping, blown fuses, or flickering lights
Two-pin sockets, cracked outlets or discoloured plates
Warm switchboard, buzzing or a burning smell
Brittle cloth or rubber cable in the roof space or subfloor
How Long Does a Rewire Take?
Most Sydney rewires run 2-6 days depending on size and access. Power is usually off during work hours and restored each evening where it is safe to do so. We coordinate with you to plan around fridges, internet and essential loads where practical.
Typical timelines
Unit (1–2 bed): 2–4 days
House (2–3 bed): 3–5 days
Large or double-storey: 5–8 days
Terrace or heritage: allow extra time for careful cable routes and wall protection
Our Rewiring Process
Site visit and fixed quote – we assess access, circuits and the switchboard.
Safety check and plan – agree staging, daily power-off windows, and room access.
Cable installation – run new circuits, remove or make safe old wiring.
Switchboard works – upgrade where required and add RCD/RCBO protection for final sub-circuits in line with current Wiring Rules
Testing and sign-off – test every circuit, label clearly, issue CCEW, tidy up.
How to prepare
Clear access to the switchboard, roof hatch and rooms we are working in
Move fragile items and cover furniture where practical
Tell us about any planned renovations, new appliances or EV charging so we can size circuits correctly
Add-Ons Worth Considering
Extra powerpoints and USB outlets in living areas and bedrooms
LED lighting upgrades to cut running costs
Smoke alarms on every level using AS 3786-compliant alarms. Hard-wired and interconnected alarms are preferred where possible, while AS 3786-compliant 10-year lithium battery alarms may be suitable in some existing homes.
Surge protection for sensitive electronics
EV-ready circuit or outdoor 15A outlet for tools or caravans. A weatherproof outdoor power point is a practical add-on for tools, caravans and outdoor areas.
FAQs
Do I need to move out during a rewire?
Usually no. We work in zones and restore power after hours where safe. If your home has very limited access or you are renovating, a short move-out can speed things up.
Will you patch walls?
We keep access holes as small and neat as practical. Minor patching may be included, depending on the quote. Full plastering and painting are usually best handled by your chosen trades.
Can we stage the rewire room by room?
Yes. Staging helps with busy households. It can add days to the schedule, so we will price both options.
