Energy labels help you compare how much electricity (and sometimes water) appliances use. In the UK, labels for several product groups were rescaled to a simpler A to G scale in 2021, replacing the old A+++ ratings. Here is how to read them and turn them into a running-cost estimate.
Which appliances have the A to G label
The rescaled A to G label applies to products including:
- Washing machines and washer-dryers
- Dishwashers
- Fridges and freezers
- Televisions and electronic displays
- Lighting
Small appliances such as kettles, toasters, air fryers and microwaves do not carry an energy label, so for these you need to look at wattage and how you use them.
What the rating means
The letter shows efficiency compared with other products of the same type. Because the scale was reset, very few products reached the top classes when the new labels launched, so a B or C rating can still be a very efficient appliance.
What else is on the label
The label also shows energy use in kilowatt-hours (kWh). Depending on the product, you will also see figures such as:
- Washing machines: energy per 100 cycles, water per cycle, programme duration, capacity, spin efficiency and noise class.
- Dishwashers: energy per 100 cycles, water per cycle, number of place settings, programme duration and noise class.
- Fridges and freezers: annual energy use, storage volume and noise.
The labels also include a QR code linking to a product database with more details.
Working out running costs
You can estimate running costs with a simple calculation:
kWh used × your price per kWh = cost
For a washing machine or dishwasher, divide the “per 100 cycles” figure by 100 to get the energy per cycle, then multiply by how many cycles you run and your electricity unit rate.
Example: a dishwasher using 60kWh per 100 cycles uses 0.6kWh per cycle. Run 250 times a year, that is 150kWh. At a unit rate of 25p per kWh, that is around £37.50 a year. Use the unit rate on your own bill, as prices vary by tariff and change over time.
Using the label to compare
- Compare products of the same size; a larger appliance will usually use more energy in total.
- Look at the kWh figure, not just the letter.
- Consider how often you will use the appliance. A more efficient model costs more up front, but saves more if you use it often.
