You don't cut an energy bill with one clever trick. You cut it by killing several small, constant drains at once. Here's where the money actually goes — and how to claw it back.

The biggest wins first

  • Heating and cooling is usually the largest cost. Drop the thermostat a degree or two and wear a layer — each degree is a real chunk off the bill.
  • Wash cooler. A 30°C wash cleans normal laundry fine and uses far less energy than a hot one.
  • Dry on a rack, not the tumble dryer — one of the hungriest appliances in the house.

Kill the quiet drains

  • Switch off “standby” devices — TVs, consoles and chargers draw power doing nothing.
  • Swap remaining bulbs for LED; they use a fraction of the energy.
  • Only boil the water you'll actually use in the kettle.
💡

Measure, then target

Check which appliances cost the most (your supplier's app or a plug-in monitor). Fix the biggest drain first — don't sweat the phone charger while the dryer runs daily.
