Cost of House Rewiring in Perth: What to Expect

Living in Perth comes with its own set of characters: sunny weather, vibrant suburbs and plenty of old homes with character. But beneath the surface, some of these properties have electrical systems that need an upgrade. Unsafe or outdated wiring isn’t just an inconvenience – it’s a risk to everyone under your roof. Over 40% of residential fires in Australia are caused by electrical faults or aging wiring. Australian fire brigades respond to many of these incidents, highlighting the importance of compliance with Australian standards to prevent such hazards. Whether you’re updating an old character home or fixing up a renovator’s delight, knowing the cost of rewiring is the first step to a safer, more reliable space. Obtaining a compliance certificate from a licensed electrician is essential for confirming that the rewiring meets Australian standards and is often required for insurance purposes.

What is House Rewiring?

House rewiring means replacing old, faulty or outdated cabling, sockets, switches and sometimes the switchboard. In many Perth homes, original wiring is well past its use by date especially for homes built before the 1980s. Signs your place may need rewiring include:

• Flickering or dimming lights
• Frequent blown fuses or tripped safety switches
• Sockets that spark or feel warm to touch
• Outlets that don’t work or are loose
• Minor shock when plugging in appliances

Degraded wiring and frayed wires are common in older homes and can pose serious safety hazards.

Rewiring a house isn’t about adding bells and whistles – it’s about getting compliant with current safety standards and protecting your investment from future fire risk. House rewiring can involve replacing old electrical wires with new, safer ones to eliminate hazards and meet modern demands. Rewiring work is essential for ensuring the safety and reliability of your home’s electrical system.

Why Rewire a House

Rewiring a house is more than just a maintenance task—it’s an essential investment in your home’s safety and future. For many older properties in Perth, the electrical system may be running on outdated or faulty wiring that no longer meets current Australian electrical standards. This can create a serious fire hazard and increase the risk of electrical faults, putting your family and property at risk.

A professional house rewiring job ensures your wiring system is safe, reliable, and compliant with the latest regulations. Upgrading your wiring also allows you to take full advantage of modern appliances and smart home technology, which often require more power and better energy efficiency than older systems can provide. Whether you’re planning to rewire a house as part of a renovation or simply want peace of mind, addressing outdated wiring is a crucial step in protecting your investment.

While the cost to rewire a house in Australia can vary depending on the size and complexity of the rewiring project, the benefits far outweigh the expense. Not only does rewiring a house reduce the risk of electrical faults and fire, but it also increases the value and functionality of your home, making it a smart move for any homeowner.

Planning and Preparation for Rewiring

Proper planning is key to a successful rewiring project. Before any work begins, it’s important to have your existing wiring system thoroughly assessed by a qualified electrician. This assessment will help identify which areas need attention and determine whether a full or partial rewire is necessary.

Homeowners should also consider the scope of the rewiring job, including the number of new power points, light switches, and any additional services like upgrading circuit breakers or installing new electrical outlets. Gathering multiple quotes from local electricians is highly recommended—look for a reputable electrician with experience in rewiring a house to ensure the work meets Australian electrical standards.

Labour costs and material expenses can add up, so understanding the average costs for your property size and the complexity of the job will help you budget effectively. Planning ahead can also minimize disruptions to your daily life and ensure the rewiring process runs smoothly from start to finish.

What’s Included in a House Rewiring Project

A comprehensive house rewiring project involves much more than just swapping out old wires. The process typically includes replacing the entire wiring system with modern copper cables, installing new power points and light switches, and upgrading electrical outlets throughout the home. Upgrades to the meter box and circuit breakers are often part of the job, ensuring your electrical components are up to date and compliant with Australian electrical standards.

Adding safety switches is another critical step, as these devices are now mandatory in Australia and provide an extra layer of protection against electrical faults. Depending on your needs, you may opt for a partial rewire—focusing on specific rooms—or a full house rewire for complete peace of mind.

The rewiring process usually takes a few days to a few weeks, depending on the size and complexity of your home. For a medium-sized property, the typical cost ranges from $3,500 to $8,000, but this can vary based on the number of new power points, the condition of the existing wiring, and any additional upgrades required.

House Rewiring Process

The house rewiring process starts with a detailed inspection of your current electrical system. An experienced electrician will assess the existing wiring, identify any old wires that need replacing, and plan the best approach for your home. Once the plan is set, the old wiring system is carefully removed, and new modern copper cables are installed throughout the property.

Next, the electrician will fit new power points, light switches, and electrical outlets, ensuring every component meets Australian electrical standards. Upgrades to the circuit breakers and meter box are completed as needed, and safety switches are added for extra protection. In some cases, the rewiring process may involve accessing attic spaces or drilling through brick walls to run new wiring, especially in older homes.

While rewiring a house can be disruptive, a reputable electrician will work efficiently to minimize mess and downtime. The entire process can take anywhere from a few days to a couple of weeks, depending on the size of your house in Australia and the complexity of the job. Investing in a professional house rewiring ensures your electrical system is safe, reliable, and ready for the demands of modern living.

Older Properties and Rewiring

Older properties, especially those built before the 1960s, often come with outdated or faulty wiring that no longer meets current Australian electrical standards. These aging wiring systems can pose serious safety risks, including an increased chance of electrical faults and fire hazards. Rewiring an older home is often more complex and may require additional work, such as installing new electrical outlets, circuit breakers, and safety switches to bring the property up to modern standards.

While the cost of rewiring older properties can be higher due to the extra labour and materials involved, the benefits are significant. Upgrading the wiring system not only improves safety but also enhances energy efficiency and supports the use of modern appliances. By investing in a professional rewiring job, homeowners can protect their property, reduce the risk of electrical issues, and increase the overall value of their home. For anyone living in an older property, rewiring is a smart and necessary step toward a safer, more comfortable, and more efficient living environment.

Cost to Rewire a House in Australia

There are a few moving parts when it comes to costs. The average cost across Australia is between $3,000 and $15,000 for a complete rewire of the entire house, depending on how big the job turns out to be. Rewiring costs can vary significantly based on the size and complexity of the property.

• For a small unit or 2 bedroom house you might pay between $4,000-$6,000.
• A 3 bedroom house sits in the $6,500-$9,000 range.
• A 4 bedroom (or bigger) property will need a budget of $9,000-$15,000 especially if there’s more than one level or tricky access. Larger homes require more wiring and new sockets, which increases the overall rewiring costs.

Labour costs are a big chunk of that bill – generally between $90 and $105 per hour in Perth but can be higher for more experienced tradies or urgent jobs. The electrician’s hourly rate is a major factor in the overall cost. It’s not always a straight swap either as some older homes take more time to bring wiring up to Australian standards.

After considering the cost breakdowns, keep in mind that the total cost and total project cost can vary based on the amount of rewiring work, materials, and any additional upgrades required. Rewiring expenses include not just the base rewiring price but also any unexpected costs that may arise during the project.

House Rewiring Cost in Perth

While national averages are helpful, Perth homeowners have more specific needs due to our older homes and growing suburbs. House rewiring costs in Perth can differ from national averages because of local factors such as property age, regional labour rates, and compliance requirements. Typically, prices for a Perth rewire look like this:

Partial rewiring is an option if only one area needs attention – kitchens or bathrooms usually cost $1,500-$3,000 per room, bedrooms are less depending on the amount of rewiring work required in each room, which will influence the final price.

Factors that Affect the Cost

Not every rewiring job will be the same price. Your final bill may be higher or lower based on:

• Size and layout of your house (bigger homes need more labour and more materials)
• Age and condition of the existing wiring
• How easy the wiring is to access (brick walls, low ceilings, limited access to attic space, and complex layouts add up to more labour hours)
• Type of wiring chosen (copper is more expensive than aluminium but often preferred for safety)
• Any other repairs or upgrades, like a new switchboard ($700-$2,000 in Perth for most upgrades)
• Relying on extension cords instead of proper rewiring can increase fire hazards and is not a safe alternative to upgrading your wiring.

If your home still has very old wiring or needs a switchboard upgrade to meet regulations, costs will be at the higher end.
