Most UK households use a kettle daily. While modern kettles can boil water quickly, that comes at cost to your energy bills and harm to environment from CO2 emissions and other impacts.
As it’s something you use every day, any small measures to reduce the amount of energy you use adds up over time to make a real savings. So how much does a kettle cost to run?
Kettle running costs and what you can save
A typical kettle is rated at about 3000 W. That means that running it for about 30 minutes a day costs about 15p (assuming 10p charge per kWh) – See this electricity costs calculator to play with more figures – Energy costs calculator
That adds up to about £4.50 a month and about £55 a year to run your kettle.
Across UK households, the Energy Saving Trust estimated are potential savings overfilling kettles costs British households £68 million on energy bills a year.
They go on the advise that “Kettles are one of the most commonly used appliances in the kitchen. ECO kettles that only boil the amount of water required can use 20 per cent less energy than a conventional electric kettle. On average a UK household boils the kettle 1,500 times a year.”
How to save energy using a kettle
Therefore there is a lot of potential here for saving energy and cutting bills. The advice on saving energy boils down (sorry) to two main areas:
- Not overfilling your kettle – only boil the amount of water you need, one cup should mean one cup and any more is a waste of energy and water.
- Not over-heating the water – tea MUST use just boiled water at 100oC, but other drinks like coffee (instant and ground) taste much better at 90oC. Also some speciality teas are better at lower temperatures. If you use a hot water bottle or you need some very hot water for cleaning or washing (though a dishwasher is usually more efficent), then lower temperatures are much better.
- High power so your water reaches the desired temperature quickly – within reason it’s better for your kettle to have enough power to heat water quickly. This means that there will be less heat lost while the kettle is heating up.
- Get a kettle with low heat loss walls – double wall insulation is ideal or low loss walls mean that less heat is lost while heating and the kettle is more efficient.
We currently stock two excellent ECO Kettles that can help you save energy using these principles.
Both of them have the following features:
- – Easy to use gauge so you only boil the amount of water you need.
- – Temperature settings so you the kettle shuts off quickly after reaching the pre-set temperatures of for example 80oC, 90oC and, of course 100oC.
- – Modern efficient elements that boil water quickly.
- – Good wall insulation to minimise losses during heating.

All are stylish, excellent buys that can pay for themselves within a year.
