Keep it affordable

We'd all like running our home to be more affordable; here's some tips on things you can do to help make your home more affordable to run.

Lighting | Electricity and gas plans | Water | Appliances | Fridges and freezers | Other resources |

Lighting

Switch your lights to LEDs to reduce your power bill for lighting by up to 83 percent.

Electricity and gas plans

The Powerswitch website helps you find the best electricity and gas plans – check it out to find the best options for your home and family. Keeping track of your bills will help you understand where you can make savings.

Water

How can we use less water and save on heating it? Some things you could do include:

  • shower instead of taking a bath
  • reduce your shower time
  • use cold water for your laundry
  • run the dishwasher and washing machine with full loads
  • fix your leaks
  • install a shower flow restrictor (these are reasonably priced)
  • install an efficient shower head with a flow rate of 9 litres a minute or less
  • set the thermostat of your hot water cylinder to 55–60°C (you may need a plumber to do this)
  • wrap your hot water cylinder with a cylinder wrap, to reduce heat loss and insulate your hot water pipes (at least the first 1–1.5 metres of pipes)
  • maintain your hot water system.

For more on how to save water, see our How much water do you use? page.

Council also offers 200-litre rainwater tanks for a discounted price.

Appliances

Choose energy-efficient appliances for your home. Using the Star rating system to help you choose models that best meet your needs.

Remember you can save on power by always turning appliances off when not you’re not using them – don’t leave them on standby.

Some other great ideas are:

  • Do not leave devices plugged in when they are fully charged.
  • Use timers and thermostats to reduce the amount of power you use (eg, heaters, freezers, lights).
  • Identify the appliances using a lot of power and replace them with more efficient models if you can, or try to use them less.
  • Plug a number of appliances into one power board (eg all your appliances around the TV); this means you can switch off the power board rather than appliances one by one.
  • Use your smartphone to turn on/off smart WiFi power points.

Fridges and freezers

Check that your fridge and freezer doors are sealing properly; gaps in these seals can mean your appliances aren’t operating as efficiently as they could.

Leave 3–5cm between the back of your fridge or freezer and the wall for good ventilation; poor air circulation can double how much electricity your fridge or freezer uses.

Manage the temperatures of your refrigeration appliances (-18°C for your freezer and 0–4°C for your fridge). For more information, see the Love Food Hate Waste website.
