A quick overview before you dive in:
The price of a rewire depends mainly on your home's size, age and access, but some of the cost is in your hands. Clear access, a settled plan and good timing all help avoid delays and changes halfway through.
Each tip reflects how house rewiring in Sydney is planned and quoted at Impulse Electrical Enterprise, and we work across the Inner West and greater Sydney.
New cable is run through the roof space and under the floor wherever possible, so how easily the electrician can get in affects how long the job takes. Before work starts, clear the area below the manhole and around any underfloor access, and move anything stored in front of the access points. Don't go into the roof space or under the floor to move things, and don't touch old cables; leave that to the electrician. Easier access means less time on the job, which helps keep the cost down.
If access is blocked by stored items, tight spaces or finished renovations, the job takes longer, and more time means higher labour costs.
Adding a power point or moving a switch halfway through can mean rerouting cable or reopening areas that are already finished. Before the quote is finalised, think about:
Settling these before the quote is final helps avoid changes once the work has started.
If you're renovating, rewire before the new plaster, paint and cabinetry go in. Cables can be run while walls and ceilings are open, rather than cutting into finished surfaces later and paying to make them good again.
Not every home needs a full rewire. If the rest of the wiring is sound, rewiring one area, such as the kitchen or an extension, may be all that's needed. Your inspection will show whether a full rewire, a partial rewire or no rewire is the right call, so your quote covers the work your home needs.
The lowest quote can look attractive, but if it leaves out work you need, or the work has to be redone, it can cost more in the end. Check that each quote covers the same rooms and circuits, the same number of power points and lights, the CCEW, and what's excluded, such as patching and painting. Ask each electrician how they plan to run the new cable. Running it through the roof space and under the floor where possible keeps openings in walls and ceilings to a minimum. Our guide to the cost of rewiring a 3 bedroom house shows what an itemised quote should list.
Home | Typical price |
|---|---|
1 to 2 bedroom unit | $4,000 to $6,000 + GST |
3 bedroom house | $6,000 to $9,000 + GST |
4 bedroom house | $8,000 to $12,000 + GST |
Larger or double storey home | From $12,000 + GST |
These prices assume reasonable access to the ceiling and under the floor. A switchboard upgrade, if needed, is quoted separately, and patching, plastering and painting aren't included. Your final price is confirmed in a free, fixed quote after we inspect. Our rewiring cost guide explains what moves the price.
It can spread the cost, but it may not lower the total. Where it's practical and electrically safe, a rewire can be split into stages by room or by circuit, such as lighting, general power, then the oven, cooktop and other appliance circuits, across separate visits. Any dangerous wiring has to be fixed or safely isolated straight away rather than left on until a later stage. We set the staging plan after inspecting your wiring, and your quote sets out the price.
No. In NSW, anyone doing electrical wiring work must hold an electrical licence. You can help by clearing access and settling your plan early, but the wiring itself must be done by a licensed electrician.
