The kettle will be working overtime this year, with many people opting to fill a hot water bottle rather than heating their bedroom. And with 165 million cups of tea being drunk in the UK every day, you might be wondering, how much exactly does it cost to boil a kettle?

The exact costs will vary on the size/power rating of your kettle plus your electric tariff cost. The average two-litre kettle has a power rating of three kilowatts per hour (kWh), although it must be noted that it will never take a whole hour to boil your kettle! Instead, boiling a kettle for an average of four minutes uses 0.225kWh."

Learn to boil only as much water as you need in your kettle. If you want two cups of tea, for example, then pour in water measured in those cups. Sust-it.net reckons that the price of boiling a full kettle of water will go up from 5.24p to 6.37p from October 2022, which is an increase of £12.30 per year. You also need to wait longer for a full kettle to boil.

Inyourarea.co.uk puts the new cost since October 1^{st} as:

**Full kettle (2 litres)**: 8p**Half-full kettle (1 litre)**: 4p**Two cups for tea (500ml)**: 2p

Boiling a kettle on a gas stove uses more energy but even with the gas price increases, the unit price of gas is cheaper, so boiling just the right amount on a hob costs 0.46p compared to 1.12p from the kettle.

Remember to de-scale kettles regularly to keep them at their most efficient.

Coffee machines and coffee pots

The formula to calculate how much energy a coffee machine consumes is to multiply its electrical power by the time it is in use. And if we multiply this result by the price of electricity, we will know the total cost of using the machine

If we prepare a daily coffee for a whole year on a Dolce Gusto coffee machine, the consumption in this time will not exceed 10kWh. And if we apply the above formula to the current energy price, the total use cost will be around £3 per year.

A filter coffee takes 10 mins, but will give you 10 cups and costs about 5.5p. Multiply that by 365 and you get ten times the number of coffees for a little over £20 per year.
