Average Costs to Wire a New House

Money makes the world go round, so many people’s biggest concern when it comes to wiring a new house is how much this is going to cost them. However, there is no one set price for this job, as it may depend on various factors.

The size and complexity of the job, as well as the cost of materials, fixtures and labour are all taken into consideration and influence the price. Our electricians at Radiance Electrical can provide you with an accurate figure after assessing your property and the project size.

As a rough rule of thumb, expect prices of between $3,000 and $13,000 for wiring your new home.

What’s Involved in Wiring a New Build

Wiring a new build home is a larger task than it may seem, which starts with the initial planning stage through to completion.

Wiring a new home takes planning. It is best to involve and connect all the members of your team at the earliest stage so they can work together to bring your vision to life, this includes the electricians but also the builders, plumbers and architects.

All contractors must review and agree to the plan before work gets underway, which will outline where everything in the house will go. This includes where standard household sockets may go to more complex requests such as EV chargers which require more specialised modifications to your home’s electrical system. This is essential, as it minimises the risk of mistakes that could prove costly.  

The rough-in is the second stage of construction when all framing is up and the mechanical, electrical and plumbing lines are installed. It involves laying out lines, installing electrical boxes, grounding and connecting the house to service wiring. HVAC (heating, ventilation and air conditioning) and plumbing will often go in before electrical wiring.

Once the walls have been put in during later stages of construction, wires will be connected to your appliances, so this is a good time to have these selected so they can be installed and connected.

Factors That Influence Costs to Wire a New House

The cost of wiring a new home will depend on numerous factors. These include:

The Size of the Job:
This can either be how large your property is, or how much time the job itself will take, depending on if it’s a case of rewiring the whole house or more simple things like sockets.

The Materials Needed:
The electrical components such as wire, light switches and switchboards can vary in price, and it will depend what type and how many of these items are needed. For example, the pricing of a single socket can vary between $65 and $120.

The location of your home, accessibility to the wiring, the electrician’s hourly rate (which can be between $35 and $110 per hour) and additional services that may be required will also influence the price of the job.

How Long it Will Take to Wire a New House

This, again, will depend on the size of the job and your home. However, on average expect this to take between three and 11 days. 

This may also take longer if the property is older, as they may have outdated infrastructure and the need to replace old wiring methods.

When You’ll Need to Rewire an Older House

Even if you don’t think it needs to be done, it’s better to be safe than sorry when it comes to rewiring an older house. It’s worth rewiring your house every 20 years, and you should get an electrician to check it every decade to make sure it still meets Australian electrical standards.

Some tell-tale signs that wiring may need updated include flickering lights, sparking from outlets and shocks.

Costs to Rewire an Older House

So you have a good comparison of prices, it’s best to get three quotes from electricians in your area. Many will wait to give you a final quote once an accurate assessment of the job has been done, and choosing one with experience of working in older buildings is essential.

Costs will vary due to numerous factors, but you can expect to pay between $3,000 and $10,000 to rewire a 3 bedroom house. A new switchboard could be another $700 to $1000. These expenses will keep your home and your family safe, so it’s worth doing your research and choosing the best people for the job without cutting corners to save money.
