Households are being urged to make a New Year Resolution to use energy wisely – with bad energy habits set to add up to £285 to bills this year, according to new analysis and research from Uswitch.com, the comparison and switching service.
Four fifths of households admit to at least one bad energy habit, such as overfilling the kettle or leaving lights on. There are big potential savings on the costs of running kitchen appliances like washing machines, dishwashers and tumble dryers, which are among the most energy-consuming devices in UK households.
More than a quarter of people set their washing machine at more than 40C, potentially costing up to £26 a year more than washing at 30oC, while one in six run it when it’s not full. With washing machines costing households £38 a year on average, an extra wash every week could add an extra £9 to yearly bills.

Running the dishwasher when it’s not full adds an average of £11 a year to energy bills – while not using the appliance’s eco mode could also increase costs by £28.
Another costly habit is leaving the hot tap running while doing the washing up. A running hot tap can waste 100 litres in just ten minutes, wasting 34p in energy costs. Households that do this one a week could run up an additional £20 a year.
Tea-making is an area where bad habits can quickly increase energy costs. Over a quarter of households say they fill the kettle with more water than they need, potentially adding £55 to the average £93-a-year cost of tea-making if they overfill by half every time.
The UK city with the most over-filled kettles is Brighton, with 38% of households admitting to boiling more water than they need, compared to 28% nationally and 16% in Glasgow, the place least likely to over-fill.
Six million households admit leaving the TV on when no one is watching, potentially adding £2 a year to bills, while a quarter leave the lights on when no one is in the room, which could add £12 to annual bills. Leaving devices on standby is the most common bad habit, with 40% of households saying they do this.
Uswitch is supporting the Government’s It All Adds Up energy-saving campaign by offering consumers its free power-tracking app Utrack. Utrack is designed to be linked to a home smart meter to help consumers understand their home energy consumption, monitor when they are using the most power and find ways to cut costs around the home.
Ben Gallizzi, energy expert at Uswitch.com, said: “At a time of year when we’re all coming up with New Year Resolutions, it’s a great moment to get into good energy habits and save yourself money.
“We’ve all been guilty at times of leaving the lights on or overfilling the kettle, but it’s important to remember that these habits can all add hundreds of pounds a year to our bills.
“Even with the Energy Price Guarantee, bills are higher this winter than they were last year, but there are a lot of ways households can cut down their energy use.
“Doing your best to get into good habits could be a great starting point, and saving money might be as simple as using the eco mode on your white goods and making sure you only run them when full.
“You can’t always tell if changing your habits is making a difference until you see your bill – unless you track your usage. People using the Utrack app can see the impact on their bills with hourly graphs, comparing gas and electricity use by day, week, month and year.”
