Energy Labels Explained


An appliance is an investment, so as well as the price, it’s important to think about the ongoing running costs. That’s where energy labels come in. They give you useful information about each appliance, such as the energy rating and annual energy consumption. This handy guide is designed to help you understand the ratings and get the most from your new appliance.

What do the ratings mean?

By telling you how much energy your new appliance will use, the energy rating label gives you an idea of how efficient it’ll be. The highest A+++ rated appliances use the least amount of energy, making them the most efficient, more environmentally friendly and cheaper to run.

How are the ratings calculated?

Different appliance types vary in the way they work, so the EU has developed different ways to calculate their ratings. To give you an idea, think about an A+++ rated washing machine that shows an annual energy usage of 135kWh. This is how much energy it will use over a year, and it’s based on an average of 220 cycles. With electricity costing on average 15p per kWh, this machine would cost around £20 per year to run.

Where can I find this information?

At AO, we’ve made it really easy to shop with energy ratings in mind. When you see the products listed, you’ll be able to see the energy rating for each one alongside the information. Many of our products have the EU energy label in the image section, but you’ll always be able to find detailed information in the specifications.

Energy Labels by Appliance

Washing Machines

Washing Machines

All our washing machines are rated A or above for efficiency. The average amount of energy used per annum is based on 220 cycles, at 60˚ with a full drum. You can find this information in the product specifications. There are also ways to reduce your energy consumption, such as washing at lower temperatures or using shorter cycles. Look out for efficient features too, like clever sensors that work out exactly how much water is needed.

Tumble Dryers

The annual energy consumption for a tumble dryer is based on 160 cycles. You can check the product specifications to see how many kWh are used on average per year. This will give you an idea of the running costs. Our range is rated C or above, with heat pump drying technology being some of the most energy efficient around. These models use lower temperatures and recycle warm air, rather than wasting it.

Dishwashers

Dishwashers

The good news is that dishwashers already use a lot less water than washing by hand. All our models are rated A or above for efficiency and some use a little as 6 litres of water per wash. The ratings in the specifications will tell you how much energy and water the appliance will use over a year, based on 280 standard cycles with a full load. And, we even have models with efficient features such as clever sensors and half load settings.

Cookers, Ovens & Range Cookers

To test the average energy consumption of an oven, a brick is heated using different cooking functions at different temperatures. The result that uses the least amount of energy to heat the brick to 55˚ is the one that makes it into the energy label. The cooking cavities in all of our ovens, cookers and range cookers are rated B or above, and you’ll find all this information on the product page.

Cylinder & Upright Vacuum Cleaners

Cylinder & Upright Vacuum Cleaners

Energy ratings for vacuum cleaners are a little different. They’re based on around 50 hours of use, which calculates the average amount of energy consumed per year. With vacuum cleaners, a lower energy rating usually means a more powerful model. As an example, an A rated vacuum might use an average of 26kWh. At 15p per kWh, this would be around £4 a year. A D rated vacuum might use an average of 44kWh, which would work out at around £7 a year. You can find this, and other information such as noise levels, in the specifications.
