Tips to reduce your bill
1
Switch to off-peak tariffs — run dishwashers, washing machines, and EV charging after 10pm for much lower rates.
2
Seal draughts — up to 25% of heating/cooling energy escapes through gaps in doors and windows. Cheap weatherstripping pays back fast.
3
Set your thermostat wisely — every 1°C above 20°C in winter or below 26°C in summer adds ~10% to your heating/cooling bill.
4
Compare providers annually — loyalty rarely pays. Use Energy Made Easy (Vic/NSW/QLD/SA) or Synergy Compare (WA) to find better deals.
5
Install LED lighting — LEDs use up to 75% less energy than incandescent globes and last 15–25 times longer.
6
Consider solar — A 6.6kW system can offset $1,000–$1,500/year in electricity costs and typically pays back in 4–6 years in Australia.
