Reducing my energy bills

Handy tips on how you can improve the energy efficiency of your home

We’re always looking for ways to help our customers save on household energy costs so we’ve put together some simple ideas you can implement at no cost as well as some tips that will need a little more investment but could save you money in the long term.

Save energy as well as your hip pocket

Bedroom / study

  • Avoid leaving rechargeable appliances on charge for longer than is necessary. When a charger is not in use, unplug it as it continues to use energy even if nothing is charging
  • If you have teenage children, have a chat with them about turning computers and games consoles off when not in use.

Living room

  • The cost of running an LED TV can be less than 20%of the cost of running a plasma.
  • Switch off lights and appliances at the powerpoint when you can. Leaving them on standby still uses electricity.
  • Ceiling fans are the most energy efficient form of cooling. They are relatively cheap to buy, cheap to run, quiet to operate and suitable for most rooms.
  • Draft-proofing your home could save around 20% of heat being lost through drafty, ill-fitting doors and windows.
  • Close curtains over glass areas. This keeps the warmth out and the cool in - and the reverse in winter.
  • When getting a new heating/cooling system installed, put the thermostat in the main living room, rather than its traditional place in the hallway.
  • Gas heaters are cheaper to run than electric heaters.
  • That little electric heater could be costing you more than you think!
  • Insulating your home can reduce power bills by up to 40%. If possible insulate external hot water pipes, the roof and inside wall cavities.
  • If you can adjust the direction of your heater/cooler, direct warm air down in winter and cool air up in summer.
  • Set your ceiling fan to rotate clockwise to warm up a room.

Bathroom / laundry

  • Take shorter showers and regulate the water temperature, turn hot water down rather than add cold.
  • Wash clothes in cold water and use the sun to dry clothes whenever possible.
  • Front loading automatic washing machines can use as much as half the water than top loaders, and can be more energy efficient too!
  • Take advantage of energy (and money) saving features on your machine. Soak cycles remove stubborn stains on a one-wash cycle and a suds-saver allows you to recycle soapy water.
  • Clean the lint filter on your dryer regularly to maintain full air flow. Do this little job frequently and you maximise drying efficiency and minimise fire risk.
  • If you are going away for an extended period consider turning off your hot water system and other major appliances.


  • Use your jug or kettle to boil water, rather than the stove. However, don’t fill the kettle with more water than you need.
  • Gas appliances can be more efficient than electric appliances. Also, cooking with pots and pans covered can conserve energy.
  • Newer fridges can use up to 40% less energy than those over 15 years old, so consider whether it’s time to update your fridge.
  • A convection oven can use a quarter of the energy and cook food much quicker than a traditional gas or electric oven.
  • Where possible use appliance Energy Ratings to select energy efficient appliances and systems; the more stars, the more energy efficient. For more information visit
  • Each year, defrost chest freezers once or twice and upright models twice or three times, to keep them running at peak efficiency.
  • Fridge door seals should be completely air tight. Test by closing the door over a piece of paper so that it's half in and half out of the refrigerator. If you can pull the paper out easily, the hinge may need adjustment or the seal may need replacing.
  • If possible locate your fridge in a cool place away from the oven and the sun.
  • If you have two fridges, consider getting rid of the second one – it could save you around $170 a year.
  • Give the inside of your fridge a regular clear out. It’s a simple way to stop your fridge from over-working which could reduce your energy usage.


  • Consider planting deciduous trees near windows in your home – in summer the leaves will provide shade, while in winter the bare branches will let light through.
