How Much Does It Cost to Run a Electric Kettle? (Australia 2026)
Based on the Australian National Benchmark electricity rate of 33.2c per kWh (AER Default Market Offer 2025-2026).
A standard 2200W electric kettle costs A$0.73 per hour of continuous use at national average rates (33.2c/kWh). Based on typical domestic usage, it costs approximately A$0.12 per day or A$46.64 per year.

Tips to Cut Electric Kettle Electricity Costs in Australia
- Only boil the volume of water you actually need. Boiling a full 1.7-litre kettle for a single mug wastes over 60% of the energy consumed.
- Regularly descale your kettle using white vinegar or citric acid; limescale accumulation insulates heating elements and increases boil times by up to 15%.
- Use a thermal insulated kettle if you drink tea frequently, keeping boiled water hot for up to 4 hours without reheating.
- If you have solar panels, boil water during peak midday generation and store it in an insulated thermos flask for evening teas.

vs. Microwave Oven
View running cost →A kettle is roughly 80% energy-efficient compared to 60% for a microwave, making the kettle faster and cheaper for heating water volumes above 250ml.
vs. Electric Hob / Stove
View running cost →Electric ceramic hobs take over twice as long to boil water and lose significant heat to the air compared to an enclosed immersion kettle.

Frequently Asked Questions: Electric Kettle Electricity in Australia
How much does it cost to boil a kettle once in the UK?â–¾
At the current UK energy price cap of 24.5p/kWh, boiling a standard 2.2 kW kettle for 2.5 minutes (0.09 kWh) costs approximately 2.2p. Boiling a full 1.7-litre kettle from cold takes around 3.5 minutes and costs about 3.1p.
Does a 3000W rapid boil kettle use more electricity than a 2000W kettle?â–¾
No. While a 3000W kettle draws more electrical power at any given instant, it boils the water proportionately faster. The total kilowatt-hours (kWh) consumed to heat 1 litre of water is virtually identical (approx. 0.11 kWh).
Is it cheaper to boil water in a microwave or a kettle?â–¾
An electric kettle is cheaper for boiling more than one mug of water. The immersion heating element transfers approximately 80% to 85% of electrical energy directly into the water, whereas a microwave magnetron is only 55% to 65% efficient.
How much can I save per year by not overfilling my kettle?â–¾
According to the Energy Saving Trust, avoiding overfilling your kettle saves the average UK household between £10 and £14 per year on electricity bills, or up to €18 annually in Germany.
Do eco kettles with variable temperature settings save electricity?â–¾
Yes. Heating water to 80°C for green teas or instant coffee instead of bringing it to a rolling 100°C boil consumes roughly 20% less electricity per cycle.
