What should I look for when choosing appliances?

When looking for energy efficient appliances for your home, you need to look out for the energy ratings label on appliances and consider the size of the appliance that you require.

How do energy labels work?

In general, energy ratings are categorised by the product’s size. This means that two differently sized appliances with the same energy rating might use different amounts of electricity. For instance, an A rated 180-litre fridge freezer could cost only £43 a year to run, whereas a larger 525-litre fridge freezer with a better A+ rating could cost £57 a year to run.

It is best to check energy labels on products and look for the product with the best energy rating for the size you require.

Avoid leaving appliances on standby

The average UK household spends £35 a year powering appliances left on standby.

Standby is the energy used by certain appliances when not in use and not switched off at the plug. As well as standby power, other new additions to the average household’s collection of electrical goods such as broadband modems, broadband routers, smart speakers, digi-boxes and telephones use low levels of electricity when not in use. We tend not to think to switch these off, but as they’re often on for 24 hours a day, these appliances gradually consume a great deal of electricity.

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. 

EU Regulations specify that non-networked electrical devices sold after 2013 cannot have a standby power greater than 0.5W, and networked-connected devices (for example, televisions or games consoles connected to the internet) must not consume more than 3 to 12 W depending on the product. But, with many households using more electronic gadgets, it is worth looking at your standby usage.

Choose your appliances wisely

The table summarises common appliances for the home and key considerations for each appliance type. 

Home appliances and key considerations

Appliance type


Kitchen appliances


We recommend choosing an oven with an energy rating of A+.  A pyrolytic function can also be an energy intensive means of cleaning which can contribute to higher running costs.  The energy label is now found on both electric and gas ovens, enabling consumers to make the most efficient choice for either fuel.

Microwave ovens

Microwaves often provide a much more energy efficient way of cooking food than in the oven. Unlike ovens, microwaves only heat your food and not the air-space inside.


Dishwashers can take up a significant chunk of your electricity bill, typically costing between £37 and £48 a year to run. Slimline dishwashers typically cost between £23 and £37 a year to run. The most efficient dishwashers on the market have an A+++ rating, they cost around £7 less to run than the lowest rated dishwashers that you can buy of the same size, and they use less water.
Fridges, freezers and fridge-freezers                                                                                             These are switched on 24 hours a day, 7 days a week, so it's worth finding models that are energy efficient. Typically choosing an A+++ fridge freezer over an A+ unit will save you about £190 in energy bills over the 17-year lifetime of the product. However, as the energy rating is categorised by size, choosing a smaller fridge will use less energy than a larger fridge with the same energy rating. You can compare the total energy consumption of appliances by looking for their yearly energy consumption in kWh / annum - it’s displayed on the bottom right of the energy label.
Kettles 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. The average UK household boils the kettle 1,500 times a year.
Tumble dryers  

Drying clothes outdoors on a washing line costs nothing and uses no energy, so it is the ideal way to dry your clothes. Indoors on a rack can also be a no-cost, no-energy solution, although you should be mindful of the increase in moisture levels. Keep the room ventilated so that that moisture doesn’t turn into damp. If you need a tumble dryer, choosing one with an A+++ energy label over an A-rated one could save you around £370 over its 13-year lifetime.

Some have sensors that tell you when your clothes are dry enough, preventing you from wasting energy by over drying your laundry.
Electric heat pump tumble dryers are more efficient as they recycle the heat from the ventilation tube back into the dryer after removing the water vapour from the air.
There are also gas tumble dryers. This type of dryer can be slightly more expensive to install, as it needs a gas connection.
Washing machines An energy efficient machine will save you money on your electricity bill and, if you have a meter, your water bill too. Choosing an A+++ washing machine over an A+ one could save you around £65 over its 11-year lifetime. Try to wash only once you’ve enough laundry for a full load, and at low temperatures, to maximise your savings.

Computer equipment

Desktop, laptop PCs and tablets

Laptops typically use 85 per cent less electricity over a year than desktop PCs. Choosing a laptop over a desktop and reducing standby could save up to £17 per year.

Tablets have even lower energy usage - on average, tablets use 70 per cent less power than laptops.

Home Entertainment

Smart speakers and DAB radios 

Smart speakers generally cost around £5 per year to run. Usually these  appliances  are left on standby, so it is worth considering whether you do need them on 24-hours a day.
Digital radios are a popular electronic product. They don’t tend to use much energy, but consider switching them off when you leave the room and not leaving them on standby.


Televisions can be the most power-hungry of all entertainment equipment, particularly the largest ones. The larger a television screen, the more energy it will consume, regardless of its energy rating. For instance,

Running costs per year

32” TV

40” TV

60” TV














In our cost comparison table, even the most efficient 60” television is still more expensive to run per year against the lowest rated 32” television. By choosing a smaller television, you are generally saving more energy.

LED screens are the most common form of flat-screen TV on the market. LED TVs use an LCD (liquid crystal display) and LEDs provide the backlighting to create the picture.

OLED and QLEDs are similar to LED screens in that they both use an LCD display. The difference with OLED and QLED is that you don’t require backlighting, each pixel lights itself. Both types boast very high performance in picture quality; however, currently these do come at a premium.

Power consumption is mostly dependent on level of brightness and hours of use. After selecting the smallest TV still suitable, the best ways to save energy are to reduce brightness settings to your lowest acceptable limit and remember to switch off your TV when not in use. Many TVs incorporate features to do this automatically, such as light sensors to detect the room’s brightness and adjust the screen accordingly, and sleep timers to switch off the TV after a number of hours of no interaction.      

Plasma TV production ended in 2015. And since 2014, lamp lit LCDs (as opposed to LED lit) are in very limited production. Both of these TVs use more power than the LEDs discussed above.

What should I do with my old appliances? 

Electrical items should be disposed of carefully due to the nature of their materials. 

Items which have the image of a wheelie bin with a cross on them should not be disposed of using the general household rubbish collection. These items include everything from large white goods to energy saving light-bulbs. By keeping waste electrical equipment separate from other waste, the hazardous substances can be removed and other parts can be recycled rather than sent to landfill.

Disposing of waste electrical and electronic equipment (WEEE)

If you are buying new electrical appliances, the law obligates retailers to either:

  • Take your old appliances off you for free in store.
  • Tell you where you can take your old item for recycling free of charge.

Many retailers offer collection of old appliances from your home, although they are not obliged to do this.

Alternatively you can take your old equipment to your nearest recycling point, or ask your local authority to collect your bulky items. Some may charge for this service.
