Where the money goes
Estimated breakdown for your configuration
Rewiring is disruptive, cable has to be run through walls and ceilings, so it is far cheaper done during a renovation when walls are already open. Budget for make-good plaster and paint.
Ways to save
- Rewire during a renovation while walls and ceilings are already open, to save on access and make-good.
- A partial rewire of problem circuits is far cheaper if the rest of the wiring is sound.
How we estimate this
Rewiring a house in Australia typically costs $3,500 to $25,000 in 2026 depending on home size and scope. A partial rewire of a small home is cheapest; a full rewire with a switchboard upgrade on a large two-storey home reaches the top.

What a rewiring house costs in Perth
A house rewire in Perth is priced from the count of power points, light points and circuits, plus a new switchboard, because the labour is running fresh cable to every outlet and fitting, so a bigger home with more points costs more. The scope sets the first figure: a full rewire renews all the wiring and the board, while a partial rewire tackles only the aged or overloaded circuits.
Perth's common double-brick construction is the standout factor, because chasing cable through solid double-brick walls to each point is harder and messier than fishing it through a timber-framed cavity, needing walls chased and patched, so a double-brick home's rewire carries more labour than a timber one in the eastern cities, and surface conduit is sometimes used to avoid chasing. The trigger is usually old, unsafe wiring in an older home. The dry Mediterranean climate is otherwise kind to wiring compared with the humid north. The isolation of the WA market rarely affects standard cable, which is stocked locally. Labour sits near the national average, and a rewire is cheapest with walls open in a renovation or during a re-render.
A house rewire is licensed electrical work that must be carried out by a licensed electrician in Western Australia under the state regulator, and the finished installation is tested and certified. For a Perth home, the clearest way to price a rewire is by the number of points and circuits plus the switchboard, with the double-brick wall the main labour driver and full-versus-partial scope the other lever.
