What is the price of Rewiring?

Are you thinking of hiring an electrician to rewire your home? Here’s a handy price guide to give you an idea of what to expect when you’re hiring an electrician to rewire your property.

What is Rewiring?

If your property is over 30 years old and still has its original wiring, it’s likely to need rewiring. This is because wiring can deteriorate or become damaged over time. Modern standards have evolved to ensure safety, so most older properties won’t meet these new safety standards.

To make sure that your wiring complies with the latest safety standards, it’s recommended that it is inspected every 10 years by a registered electrician. Even newer houses may require rewiring if the existing wiring is damaged or has been tampered with by a DIY-enthusiast.

Rewiring a house typically involves the switchboard being upgraded and the existing wiring replaced. This is also a good time to choose to have more power outlets added to your home for your appliances, phone chargers, televisions and computers, or extra switches for your convenience.

If you’re planning a renovation project such as converting your attic or garage into a living space or extending your home, you’ll probably need to rewire your home first. This is because your existing wiring will need to be upgraded to safely carry the additional load.

Rewiring your home is often a major job and a large expense. However, it’s not worth taking the risk with potentially dangerous wiring. Old or faulty wiring can cause circuits to blow, frequent power cuts or even electric shocks and house fires, so it’s imperative to book an inspection with an electrician if you suspect that your home may need rewiring.

How much does Rewiring cost?

There’s no denying that rewiring your property can be costly. However, it’s often essential for both safety and modern convenience. It’s important to know how much rewiring your home is going to cost before you commit to hiring an electrician.

There are many factors that will influence the cost of rewiring your property. The most significant of these is the size of your home. Although there is no fixed rate, a breakdown of average costs of rewiring a home based on local Australian professionals is given below.

Minimum cost$2,000
Maximum cost $12,000

What changes the price of Rewiring?

The price of rewiring your home will depend on several factors including:

  • Property size

  • Whether a full or partial rewire is required

  • Location

Property size

The biggest consideration when thinking about the price of rewiring your home is the size of the property. The larger your house, the more wiring needs to be done and the more costly it will be. There will be much more wiring to replace in a four-bedroom house than in a one-bedroom apartment, so it will therefore be more expensive to replace.

There’s no set price when it comes to rewiring different sizes of property. However, a breakdown of average costs of rewiring a home based on local Australian professionals is given below.

Average cost of Rewiring based on property size
House sizeAverage cost of rewiring
One-bedroom apartment$2,000
Two-bedroom townhouse$4,000
Three-bedroom townhouse$6,000
Four-bedroom detached$11,000

Full or partial Rewiring

You may be able to save money by partially rewiring your home instead of doing a full rewire. This can be done if the existing cabling is in good, safe condition and able to carry any additional loads required.

If you’re rewiring your property in preparation for renovation work such as a garage or attic conversion or a home extension, you may be able to choose to partially rewire your property to keep the costs down. Partially rewiring involves upgrading to a new switchboard to give you the capacity for the additional load required.

The average price of upgrading to a modern switchboard can vary. However, a breakdown of average costs is given below.

Average cost of upgrading to a modern switchboard
Average cost $500
Minimum cost$250
Maximum cost$800


There may be regional variances in the cost of hiring an electrician to rewire your property, depending on your location. The hourly rate for an electrician varies between states, so the cost of rewiring will depend on where you live.

Prices are typically higher in Western Australia, Tasmania and South Australia, while they’re cheaper in New South Wales, Victoria and Queensland. However, the prices will still typically fall within the ranges above.

Is it worth getting Rewiring?

If your existing wiring is damaged or deteriorated, it could pose a hazard. As well as causing power cuts and fuses to trip, poor wiring can also lead to electric shocks and house fires if not dealt with.

When you’re extending your home or converting your garage or attic into living space, you’ll likely need to rewire your home first. This is to create capacity for the additional circuits required for the new living space.

If you’re moving into an older property, you’ll need to check when the house was last rewired. The chances are, your wiring will need to be updated. Old wiring typically doesn’t stand up well to today’s modern safety standards and isn’t built for the capacity we need today, so it will probably need updating.

If you think your home may need rewiring, it’s always best to contact an electrician to carry out an inspection. After all, they’re the experts. They’ll be able to tell you whether there are any safety issues with your current wiring and whether it could be improved through rewiring.
