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 Sydney
A house rewire in Sydney is priced mainly by the number of power points, light points and circuits the home has, plus a new switchboard, because the labour is running new cable to every outlet and fitting, so a larger home with more points costs more than a compact one. A full rewire replaces all the old wiring and the board, while a partial rewire tackles only the worst circuits, so the scope is the first thing that sets the figure.
Wall access is the hidden driver in Sydney, because fishing new cable through the walls and ceilings is quick in a timber-framed home with an accessible roof and subfloor, but far harder in a solid-brick or rendered terrace in the eastern suburbs where cables must be chased into masonry and the walls patched. The trigger is usually old, unsafe wiring, so a period terrace with original rubber-insulated or early wiring is a common full-rewire, often done during a renovation when walls are open and the cost drops. The city's highest trade rates lift the labour, and a strata apartment's rewire may need owners corporation coordination where wiring is shared.
A house rewire is licensed electrical work that must be carried out by a licensed electrician in New South Wales under NSW Fair Trading, because it is extensive fixed wiring, and the finished work is tested and certified. For a Sydney home, the clearest way to price a rewire is by the number of points and circuits plus the switchboard, with the wall type and whether it is a full or partial rewire the main levers, and a renovation the cheapest time to do it.

Frequently asked questions
How is a house rewire priced in Sydney?
Mainly by the number of power points, light points and circuits plus a new switchboard, because the labour is running new cable to every fitting, so a larger Sydney home with more points costs more, and a full rewire costs more than a partial one.
Does the wall type affect a rewire in Sydney?
Yes. Fishing cable through a timber-framed home with an accessible roof and subfloor is quick, but a solid-brick or rendered eastern-suburbs terrace needs cables chased into masonry and the walls patched, which lifts the labour on a Sydney rewire.
When is a rewire cheapest in Sydney?
During a renovation, because the walls are already open so the electrician can run cable without chasing and patching, which drops the cost of what is usually triggered by old, unsafe wiring in a period Sydney terrace.
Do I need a licensed electrician to rewire in Sydney?
Yes. A house rewire is extensive fixed wiring that must be carried out by a licensed electrician under NSW Fair Trading, and the finished work is tested and certified, because it is licensed for safety in Sydney.
