When should you rewire a house?


‘Out of mind, out of sight’ is an adage that can be easily applied to the electrical wiring of an older home, particularly when there are no obvious problems with the lighting or electricity. However, there are many reasons why it’s worth asking an electrician to take a look at wiring in older homes.

The Main Reason for Rewiring A House Is Safety

The danger of non-compliant, or degraded wiring in older homes is the most obvious reason to consider re-wiring a home. There is a very real danger of electric shock or injury from non-compliant or deteriorated electrical wiring. Residential fires are another concern, and many of these occur every year due to wiring faults. Some older homes may not have mains powered smoke alarms installed which are a mandatory clause within the Building Code, adding further to the risks associated with electrical fires. For this reason, DIY wiring – or undertaking any electrical work if you are not a qualified electrician is a recipe for disaster.

We use so many appliances in modern life, from computers to TVs, from home theatre systems to kitchen appliances. Older homes are often simply unable to cope with our changing electrical needs. The majority of older homes only have one circuit for power outlets and one for lighting with NO safety switch protection. Upgrading the wiring in older homes can enable you to set up different circuits as needed, along with complying with the latest safety standards, so your family can function more easily in their day-to-day technological life. Wouldn’t you love additional power points in some rooms, and to put them exactly where you need them? What about the option for dimmer switches on lights, or to change to energy efficient lighting, even home automation can now be considered. If your electrical switchboard looks like the image shown here, it’s probably time to consider upgrading.

Other Considerations

  • Smoke Detectors – required by law, smoke detectors are best if they are hard-wired in and have a battery for back-up
  • Safety Switches – safety switches are mandatory in all new homes and for any new power points and lighting circuits installed within existing homes. They can prevent fatal electrocution and they also provide protection for appliances in your home. Recent changes to law require all existing homes to have a safety switch installed when any additional lighting circuits, fans or power points are installed.
  • Value-adding – rewiring a home will be far more attractive when you come to sell your property, both for safety and practical reasons

When you should worry

Get an electrician in to check the wiring in your older home if:

  • Fuses blow often
  • Your lights flicker or dim regularly
  • You can smell a persistent burning smell from an appliance or area of your home
  • Your power points feel warm or look discoloured
  • You suspect dodgy wiring may have been carried out in your home by previous owners

What does it cost to rewire a house

It generally costs anywhere from $3500 – $5000+ to rewire the typical 1950’s style 3 bedroom home and this cost includes upgrading the switch box. Without inspecting the home it’s very difficult to put an exact figure on what it would cost you to rewire your home, but that seems to be the average cost. Be mindful that there are many factors to consider that could affect the final cost and don’t forget to allow for the cost of new light and fan fittings.
