Energy Efficiency at Home

As the temperature starts to drop and you begin the annual quest to find your hot water bottle, we wanted to bring you the hot tips to reduce your energy costs, while increasing the comfort of your home. 

These are the quick wins that have minimal cost, require minimal effort and result in big dollar savings. 


  • Keep the thermostat below 20°C. Every degree higher will increase running costs by around 10%.
  • Close off rooms not in use so you only heat the rooms you are using.
  • Turn the heater off overnight or when you go out, don’t leave it running.
  • Seal up any gaps and cracks under and around doors and windows, use draught excluders and weather stripping on doors and windows, cover evaporative cooler outlets, seal wall vents.
  • If you are going to buy a new heater use the energy rating labels to upgrade to a high efficiency heater.

White Goods

  • Turn off that second fridge when it’s not needed
  • Check your fridge and freezer seals, clean and replace damaged seals.
  • Check that the heat exchange coils at the back of the fridge are clean and well ventilated.
  • Wash clothes with cold water whenever possible
  • Only run your dishwasher when it’s full.

Hot Water

  • Take shorter showers; use a shower timer to make sure everyone has a four minute shower.
  • Install a low flow shower head and save water and energy.
  • Insulate hot water pipes leading from your hot water system into the house.


  • Use natural lighting wherever possible.
  • LEDs use much less energy to provide the same amount of light as other forms of lighting. 
  • Switch the lights off when you leave the room and in rooms that aren’t being used

TV and Home Entertainment

  • Turn the TV and entertainment appliances off at the wall when they’re not being used. They are still drawing power in standby mode.
  • Install a ‘standby-killer’ switch or a standby power controller (SPC) to disconnect power to appliances when they’re not being used.


  • Only heat the amount of water you need, if you are making a cup of tea for one or two don’t overfill the kettle.
  • Keep lids on pots and pans when cooking and use the right sized pot for hob.
  • Cook in bulk and freeze the excess.
  • Use the microwave for cooking whenever you can, but switch the clock off. More energy is used to power the clock than to cook food.

Additional tips

  • If you do need to upgrade any appliances, choose ones that have a high energy rating. 
  • Appropriate window protection creates an insulating layer of still air on the inside of the glass. This can be achieved by the addition of thick curtains and a pelmet.
  • Using rugs helps to prevent heat loss.
