Energy labels show how efficient an appliance is, so you can compare models and estimate what they’ll cost to run. Since 2021 most major appliances in the UK have used a simpler A to G scale. This guide explains why the label changed, how to read it, and what to look for when you choose a new appliance.
Why the energy label changed
Appliances are now far more efficient than they were 10 or 15 years ago. Under the old scale, so many products had reached A+, A++ or A+++ that the label no longer showed the real differences between them. The scale was reset to a simple A to G, which makes those differences clear again.
The top of the new scale was deliberately left almost empty when it launched. That leaves room for more efficient products in future without the label going out of date again.
How to read the new label
The exact details depend on the type of appliance, but most new labels show:
- The energy class, from A (most efficient) to G (least efficient).
- Energy consumption in kWh. For washing machines and dishwashers this is per 100 cycles of the eco programme; for fridges and freezers it’s per year. This is the figure to use when you compare running costs.
- Key product information, such as capacity, water use per cycle and the length of the eco programme.
- A noise class from A (quietest) to D, alongside the noise level in decibels.
- A QR code on many labels, which links to more detailed product information.
Two appliances with the same energy class can use different amounts of electricity, especially if they’re different sizes. The kWh figure on the label tells you more about what you’ll actually pay to run it.
Which appliances use the new label
The A to G label was introduced first for the products that needed it most:
- washing machines and washer dryers
- dishwashers
- fridges, freezers and wine coolers
- TVs and other electronic displays
- light bulbs and other light sources (from September 2021)
Other appliance types, including ovens and cooker hoods, are being moved to the new scale on their own timetables. Until then they keep the older label, which can still show grades such as A+ or A++. Always compare products using the same type of label. Tumble dryers are part of this change in Great Britain: new rules came into force on 10 April 2026, and the new A to G label, which also shows a repairability class, replaces the old one from early 2027. Until then you may see either label on tumble dryers.
Moving from the old label to the new one
Between 1 November 2020 and 1 March 2021, manufacturers supplied both versions of the label with their products. From 1 March 2021 the new label became the one that counts, and retailers had until 18 March 2021 to update the labels shown in store and online.
Energy efficiency and your energy bills
A more efficient appliance (closer to A) uses less electricity for the same job, which can lower your energy bills over the life of the appliance. Appliances that run every day, such as fridges and freezers, or that run often, such as washing machines, tumble dryers and dishwashers, are where efficiency makes the most difference.
Choosing the right appliance
When you buy a new appliance, think about:
- Energy efficiency: look for a higher energy rating (closer to A), and compare the kWh figure.
- Noise: check the noise class (A to D) and the decibel figure, especially for open-plan kitchens.
- Size and capacity: choose an appliance that fits your space and suits how much you use it. A bigger appliance than you need uses more energy.
- Features: look for the features that suit your needs.
- Build quality: choose a well-built appliance from a reputable manufacturer.
- Price: weigh the price against what a more efficient model could save you over its life.

Frequently asked questions
Why are some products labelled differently?
Not every type of appliance has moved to the new A to G scale yet. Products such as ovens and cooker hoods may still carry the older label with grades like A+ or A++. Compare like with like: an A+ oven and a B washing machine are rated on different scales.
Why does an appliance I bought before 2021 have a different rating now?
If you bought an appliance rated A+++ before the change, it would probably have a lower letter under the new scale. The appliance hasn’t changed, only the scale. The new label is also based on tests that better reflect how products are used at home. When the scale was reset, most of the best products on the market were rated B or C.
Is a B-rated appliance a poor choice?
No. Because the top of the scale was left almost empty, a B or C rating on the new label can be among the most efficient models available. Check the kWh figure to compare models properly.
