How much does it cost to rewire a house in Australia?


When it comes to wiring your home’s electricity, safety should always come first. Old, broken, or out-of-date wiring can put you, your family, and your home at risk of a fire. Upgrading or rewiring your house is a big investment, but it is necessary to make sure that your home’s electrical system is up to code and safe. In this article, we’ll tell you everything you need to know about how much it costs to rewire a house in Australia. This will help you know what to expect.

Factors that influence the cost of rewiring a house

A standard single-phase power supply has two wires, one active and one neutral. It provides 240 volts of power and is used in most residential houses and businesses.  

Three-phase power has four wires, three actives, and one neutral, and can supply 240V and 415V power. When we bring in a three-phase supply, we triple the amount of power available. This is because we have access to all three phases, implying that we have three single-phase supply connections.

Three-phase power is more efficient than single-phase power because it allows for higher currents and voltages without experiencing losses from the inductive impedance. Additionally, three-phase systems are less likely to experience voltage imbalances, which can damage equipment or cause blackouts.

How does three-phase power work?

The cost of rewiring a house in Australia depends on a number of things, such as:

  • The size of your home. The cost will go up the bigger your home is because you will need more wiring, which will cost more.
  • The complexity of the wiring. Rewiring will cost more if you have a complicated electrical system with many outlets, lights, and appliances.
  • The type of wiring. The cost of rewiring will depend on whether you use traditional copper wiring or newer, more expensive options like aluminum or fiber optic wiring.
  • The location of your home. If you live in a rural or remote area, the cost of rewiring may be higher because the electrician will have to pay for gas and time to get to your house.
  • The age of your home. The cost will go up if the wiring in an older home needs more work to bring it up to code.

The average cost to rewire a house in Australia

Have a look at your main switchboard/meter board. Single-phase electricity setups have a single “service In Australia, rewiring a house costs an average of between $3,000 and $12,000. This cost estimate includes both labor and materials and is based on a standard electrical system in a home of average size. Remember that this is just an estimate and that the real cost will depend on the things we talked about above.

The second way to tell is by looking at your main switch. If it is 1 pole wide or one finger in width, then your electricity supply is single phase. If the main switch has three poles, which is about three fingers in width, you presumably have three-phase power.

Tips for reducing the cost of rewiring your home

There are several advantages to using three-phase power. First, it is more efficient than single-phase If you want to cut down on the cost of rewiring your home, keep these things in mind:

  • Do your research. Make sure you’re getting the best deal by comparing the prices of several electricians.
  • Consider doing the work yourself. If you’re handy and have experience with electrical work, you might be able to save money by doing the work yourself. But keep in mind that working with electricity can be dangerous, so don’t try this unless you have the skills and knowledge to do so.
  • Use cost-saving materials. Copper wiring is the most common material for rewiring a home. Other options, like aluminum or fiber optic wiring, can be more expensive. To lower the cost of the project, you might want to think about using a less expensive option.
  • Upgrade your electrical panel. It can be cheaper to upgrade your electrical panel at the same time as rewiring your home than to do each job separately.

Benefits of rewiring your home

Besides making your home safer, rewiring it has a number of other benefits, such as:

  • Increased energy efficiency. Upgrading your electrical system can help you save money on energy costs by making your appliances and lights run more efficiently.
  • Improved home value. A home with good wiring is worth more and will sell for more than a home with old or broken wiring.
  • Increased reliability. If your home is properly wired, there will be fewer power outages and electrical problems, giving you a more reliable electrical system.


When it comes to electric power, there are two main types: single phase and three phase. Three phases Rewiring a house in Australia can be a big expense, but it’s a must if you want to make sure your home is safe and healthy. It also lets you use the latest electrical wiring technology, which raises the value of your home and makes it more energy efficient. In Australia, rewiring a house is an important but hard job that should only be done by a trained, licensed electrician. It requires knowing the rules and laws about wiring, having the right safety gear and tools, and being able to get into tight spaces. If you are thinking about rewiring, talk to an electrician about what will work best for you. An electrician with a lot of experience will be able to give you good advice on how to approach your project and make sure it meets all the requirements for approval.
