It is hard to imagine life without electricity. But, without proper management, potential electrical hazards can cause serious inconveniences. That’s why you must consider electrical rewiring.

Almost everything now relies on electricity, may it be for communication, cooking, entertainment, work, or school. However, it can also cause potential dangers if you let outdated wiring or power overloading in your system. In these cases, you must consider electrical rewiring.

What is Electrical Rewiring?

You can compare electrical rewiring to a house renovation. It is the way to upgrade the wiring system, accommodate more circuits, and install devices to make sure that the connection is safe and sound from potential hazards. 

Moreover, it is an extensive task that requires licensed level 2 electricians since you are not allowed to conduct electrical rewiring under Work Health and Safety Regulation 2017. It involves tearing down ceilings, floorboards, and walls as the installed wires and cables are there. Furthermore, it requires professional planning, execution, and testing that only electricians can manage and process. 

When to Consider Electrical Rewiring?

You don’t need an electrical rewiring every time you experience wiring problems. It is a significant task that you only need once a decade. So, you must plan carefully and set a budget when you consider doing it. Consider electrical rewiring under these circumstances:

  • If there are knob-and-tube or aluminium wiring in your system
  • If you own old fuse box with white ceramic fuses
  • If you move to a new house or flat unit
  • If you notice any old rubber, lead or fabric insulated cabling 
  • If you have decided to purchase more appliances, especially heavy-powered ones such as washing machine, dishwasher, and heating system
  • If a storm or earthquake damages your property
  • If power overloading often occurs

It is crucial to ask electricians to assess your connection first so you would know if you really need to conduct an electrical rewiring. 

Can You Make Changes After an Electrical Rewiring is Done?

If you have decided to do electrical rewiring, it takes several days — depending on how complicated the needed tasks are. Careful planning with your electricians is a must to ensure that you would be satisfied with the output. Also, the electricians need to follow the NSW Wiring Rules to comply with the law and ensure safety. 

After your electricians have finished the electrical rewiring, note that you cannot make more changes as you don’t have a licence to work on live wires. But, you can assess the connection for the next few days. 

Check for Tripping of Circuit Breakers 

Tripping of circuit breakers is a sign of power overloading. So if it usually happens after an electrical rewiring job, then you can say that the circuits cannot handle the load of your installed appliances. There might be errors on the installation or incorrect calculation of electric load. 

Test Outlets and Switches

Of course, as soon as electricians finish the job, they test outlets and switches. But, they won’t know for sure if they have installed the components properly until you try them for several days. 

So, regularly check switches if they turn on and off the lights and devices. Also, connect appliances to outlets and examine if there are no irregularities such as sudden sparks or unusual sounds.   

Look for Red Flags 

You can never be so sure if your wires and cables transmit the right amount of voltage and current after an electrical rewiring. So, you must always be vigilant and look for these red flags of faulty wiring:

  • Sudden malfunction of appliances
  • Burn marks on outlets and switches even if they’re new
  • Dimming and flickering lights
  • Buzzing sounds and burning smells

If you notice anything suspicious regarding your connection, don’t hesitate to call your 24-hour emergency electricians to fix the issue right away. 


Electrical rewiring is an extensive task that needs the expertise of licensed electricians. You and your electrician must work together to come up with a plan and budget to ensure that the connection won’t suffer from faults. Moreover, after the electrical rewiring is done, you should not make any changes since unlicensed individuals are not allowed to do electrical works. But, you can check the system for several days and report to your electricians any unusual activities.
