We all aim to be more energy-efficient, but identifying the best products to support this goal can be challenging. Let's explore the top choices to make your home greener and your bills lower. Here's Handy Experts guide to choosing the most energy-efficient appliances:
If you are shopping for new appliances, whether for a remodel or because an old piece of kitchen equipment has finally given up, it makes sense to buy energy-efficient appliances that are as eco-friendly as possible. Doing so won't just help reduce the emissions that lead to global warming; energy-efficient appliances will help you cut energy bills, too. But where to start when shopping sustainably for energy-efficient appliances? This quick guide will tell you what you need to know.
The UK Department for Business, Energy & Industrial Strategy (BEIS) encourages us to buy energy-efficient appliances to cut emissions and make long-term savings on our bills. "When you're shopping for appliances, think of two price tags," the Department says. "The first one covers the purchase price – think of it as a down payment. The second price tag is the cost of operating the appliance during its lifetime. You'll be paying on that second price tag every month with your utility bill for the next 10 to 20 years, depending on the appliance. Refrigerators last an average of 12 years; clothes washers last about 11 years; and room air conditioners last about nine years. When shopping, consider labels and features that can help ensure that you purchase appliances with a low operating cost."
Here's what you need to know.
Appliances have Energy Star labels to help consumers identify the most energy-efficient products. This label also appears on windows, water heaters and other electronics. EnergyGuide labels (which are yellow and black so easily identifiable) will show an appliance's average annual energy consumption and operating cost so that you can compare them. In the UK, by contrast, since 2021, dishwashers, fridges and freezers are labelled from A (high efficiency) to G (low efficiency), while ovens and microwaves are rated as A+++ dropping down to D.
‘The appliance rating is based on how much energy it uses in typical use, compared with similar appliances,’ explains Joanna O’Loan, knowledge manager at the UK's Energy Saving Trust.
Getting the right-sized appliances is important. For example, a too-large washing machine or dishwasher you regularly run half-empty is far less efficient than a smaller appliance that you can always run full. Similarly, a full refrigerator is more efficient than one that's always empty. "As appliances are categorized by size, a large and small fridge might have the same energy rating, but the larger model may use more electricity.
Look for the product with the best energy rating for the size you need," Joanna O'Loan explains. This works the other way around, too: fitting air con units that are too small for your home is inefficient since they will have to be on for longer and work harder to cool your home.
Eco settings, on dishwashers for example, can help you use any appliance in a more eco-friendly way. Similarly, doing laundry at a lower temperature will save energy. Swapping out a tumble dryer for a dehumidifier will save energy and cut costs, while shopping for a refrigerator with the freezer above or below rather than side-by-side will generally be a more efficient choice.
According to BEIS, smart appliances can be much more energy-efficient than those not connected to or controlled by smart electric meters or home energy management systems because they help you use electricity at off-peak hours. "Smart appliances don't just turn off during times of peak electricity demand – instead, they use subtle ways to shift energy use," says BEIS.
"Your air conditioner may run slightly less often, or your water heater may adjust its heating cycle to operate when energy costs are lower, without impacting their performance. Or your laundry or dishwasher can be scheduled to operate when electricity rates and demand are lower."
Likely to be among the most energy-hungry of your kitchen appliances, it is worth running a dishwasher with a full load each time, using an eco-program. As we said above, choosing appliances with an eco setting is a good way to be energy efficient. These tend to use much less water and offer cold washes that don't draw energy to heat water.
Sian Bailey, dishwasher category manager for Miele says, "Over the last 20 years, Miele has reduced the energy consumption of its dishwashers by 44% and Miele dishwashers have only used six litres of water for many years compared to an average of 10-12 litres for other dishwashers."
If you're buying a refrigerator, you might like to know that this is probably the single most energy-intensive appliance you'll have in your kitchen. While fridges and freezers need to stay switched on all the time, there are ways to reduce energy consumption. Avoid overloading, minimize the number of times you open and close the door, and select ‘holiday mode’ to conserve energy while you’re away. Lee Harrington, connected home group manager at BSH Home Appliances Group, recommends investing in an app-controlled smart fridge freezer.
"If you accidentally leave the door open, you’ll receive a reminder to shut it via the app," he explains. "And, if you select SuperCooling and SuperFreezing modes via the app as you leave the supermarket with your shopping, by the time you get home, the temperature of the fridge and freezer will be lower than usual, to offset the rise in temperature when you open the door to load groceries."
Ovens are now well insulated to avoid excess heat loss and are typically favourably energy-rated. However, there are extra features to look out for. "While people in a hurry might opt for rapid heat-up options, those with more time can choose the more efficient eco mode which steadily heats food, avoiding the initial surge," advises Lucy Dunstan, product manager at Smeg. Cooking several dishes at once and avoiding opening the door too much also helps make your appliance more efficient. "Induction hobs are considered more energy efficient than other hobs," adds Lucy.
The induction process heats only the base of the pan, rather than the hob, so heat loss is minimized and energy efficiency maximized. Using a microwave to cook when you can is also more energy efficient than using an oven since only the food and not the oven is heated.
Shopping for the best electric kettle or considering a boiling water tap? Avoiding overfilling your kettle can save energy but an alternative is to invest in a boiling water tap, which can save energy, as Stephen Johnson, managing director of Quooker explains. "Considering the average kettle uses 2,200W to boil 1.7 litres of water and is used several times a day, only 10W per day (rather than per use) is needed to keep the water in the Quooker high-vacuum insulation tank at boiling point, ready to deliver boiling water instantly."
Washers that are energy-efficient can cut your energy and water bills, and though typically more expensive, the best can save £160 over their lifetime. "Try to wash only when you have enough laundry for a full load, and at low temperatures, to maximize your savings," say the experts at Energy Savings Trust. Tumble dryers can be bigger energy-guzzling culprits, so it's absolutely worth shopping for an energy-efficient appliance here – you could save up to £782 on energy bills over its lifetime.
Other than the energy label, look for those that have sensors that tell you when your clothes are dry so you don't run the appliance unnecessarily, and consider swapping to an electric heat pump or gas tumble dryers, both of which are more efficient. Or, as we said above, swap to one of the best dehumidifiers you can find, which typically uses far less energy. Drying clothes outdoors when you can is also a no-brainer.
Any appliances that heat or cool will use the most energy, which puts refrigerators, air con units, home heating and ovens firmly in the frame. Next, look to laundry appliances as high-energy consumers.
Whether your appliances are energy-efficient or not, leaving them on standby will guzzle more energy and add to your bills (an average household spends around £70 on appliances on standby). "Fortunately there are a number of products available to help cut down your standby electricity consumption, such as standby savers that allow you to turn all your appliances off standby in one go. Some come with timers and others come with a single off-switch," says the experts at Energy Saving Trust.
