Tips To Reduce Your Summer Power Bill

Written by Senior Electrician
Updated: Nov 2026

Perth summers can result in brutal electricity bills due to constant air conditioning use. A few smart changes can keep you cool without breaking the bank.

Important Safety Warning

If your AC keeps tripping the power or the plug gets hot, the circuit may be overloaded. Stop using it and get it checked.

Common Signs & Symptoms

  • Bill shock after summer months
  • Aircon running constantly but struggling to cool
  • House feeling hot despite AC
  • Inefficient appliance usage

Potential Causes

Why is this happening? Here are the most common reasons we see in WA homes:

  • Setting the AC temperature too low (e.g., 18°C instead of 24°C)
  • Poor insulation and lack of shade on windows
  • Running old, inefficient appliances
  • Leaving pool pumps and second fridges on constantly

Troubleshooting Steps (DIY Safe)

  • 1
    Set your AC to 24°C. Every degree lower increases running costs by about 10%.
  • 2
    Close blinds and curtains during the day to block radiant heat.
  • 3
    Use ceiling fans alongside your AC; they cost pennies to run and make the room feel much cooler.
  • 4
    Utilize delay start features on dishwashers and washing machines to run them during solar-producing hours or off-peak times.

DIY vs Professional

In Western Australia, it is illegal to perform your own electrical work. While you can change a lightbulb or reset a switch, anything involving wiring or removing fittings must be done by a licensed electrician.
