Overfilling kettles costs Britain £68m a yearReport offers advice on saving energy and water
05 July 2013
Britons are adding to their energy bills by failing to use household appliances such as washing machines, dishwashers and kettles efficiently, according to a new report.
The report by the Energy Saving Trust (EST) states that three quarters of households boil more water than they need when using a kettle, costing Britain £68m a year.
Which? kettles expert Matt Clear said: 'Boiling two cups of water in a kettle when you only need one not only uses around 64% more energy according to our testing, it also takes around 62% longer. That's why we always take the minimum amount the kettle can boil into account when rating a kettle.'

Saving money on your washing machine
While most people usually wash their clothes at 40°C, only a quarter typically use a 30°C setting.
We've found in our tests that washing at 30°C will save you between £8 and £18 per year compared with washing at 40°C. Using a should get you nearly the same cleaning results, too, although we recommend you wash bedding and towels at 60°C.
It's also important to make sure that you have an efficient washing machine. The washing machines we’ve tested have annual running costs that vary from £13 to £50 - a difference that will add up over the years, so take a look at our Best Buy washing machines.
Dishwasher vs washing by hand
The report found that the average British household washes dishes by hand 10 times a week, but only uses the dishwasher three times a week.
Larger households could actually make greater energy and water savings by using an efficient, modern dishwasher rather than washing by hand.
We've put together a dishwasher energy costs tool that shows how much a dishwasher will cost to run over its lifetime, as well as what it costs to buy, so you can get a true picture of which are the best-value dishwashers.
