When making improvements to your home, one of the best investments you can make is to have your home rewired completely. If your home is built post 1990 then your wiring should be fine, however if your house is older – generally the wiring hasn’t been upgraded since it was built. The original wiring could be fifty or even sixty years old. New wiring in your existing home could achieve a significant improvement in the functionality and most importantly the safety of your home. Lets consider the costs and benefits of getting the wiring replaced in your home.

 

Why do you need to rewire your home?

If you’re thinking about renovating, or you’ve just bought an established home with dodgy or old electrical wiring, you will likely have to have your home rewired. When renovating, rewiring your house is often a task that can be overlooked. Because your electrical wires are out of sight, they’re quite often out of find. Many homeowners don’t consider their electrical wiring a priority when moving into a house or renovating, unless they’re having electrical problems already.

Having your electrical wiring up to date and in compliance with Australian standards is so important in the prevention of electrical fires, electrical shock or other hazards. Many people who purchase older style homes, may not even be aware that some of their electrical work has been done by a DIY handyman. It’s likely that your old wiring is not only outdated, but it can be incorrectly installed and potentially life-threatening.

Most older homes actually operate on only one circuit for all power outlets. This means that all of your appliance that are plugged in at any given time are powered from the one point. This is evident when a fuse keeps blowing for example when you have the hairdryer and the microwave on at the same time. This is when a complete house rewire becomes necessary. When your electrician rewires the house circuits they will put different areas onto different circuits, thus eliminating the chance of overloading your circuits and tripping your power.

You also need to consider whether your main switchboard will need to be updated. Many older homes don’t even have a proper earthing system installed or up-to-date. This will also mean you probably need Residual Current Devices installed.

 

How much is rewiring going to cost?

It’s pretty tricky to provide an exact answer on how much it will cost to rewire your home. There are several factors that come into play, and this will refflect in the cost of rewiring.

  1. How much cable you require – the metreage required in your home will depend on how many circuits you’re installing and the size of your home
  2. Ease of access to get to the wiring – if you’re ripping walls down and wiring is easily accessible it will mean less labour hours and lower costs for you ultimately
  3. Type of wiring and fittings – copper wiring isn’t cheap (the cost of the wire alone could cost you around $600 itself), also choosing quality Australian made fittings can affect the price. The difference in one fitting along can be $40 or $50 but better you pay for quality than a cheap China knock-off.

When your getting a quote you will quite often find that the costs of rewiring will vary quite a bit. Our suggestion is you should ask questions! Why is one quote more expensive than the other? Sadly you’ll find the cheapest quote isn’t always the best – the quotes may not even be for the exact same things.

Rewiring your average three bedroom home in Sydney could be quoted in so many different ways depending on what add-ons, extras and level of protection your require. At the cheaper end would cost approximately $4000 all the way up to $9000 which might include a switchboard upgrade and metering protection device. At the end of the day you are best to find a trustworthy electrician, check their online reviews, and don’t always choose the cheapest quote.
