Which? Energy Saver logo

Which? Energy Saver logo explained

  • How Which? awards its Energy Saver logo
  • Energy-efficient products that save electricity
  • Tumble dryers, kettles, TVs and dishwashers

For products that successfully marry Best Buy performance with superb energy efficiency in our in-depth tests, we’ve introduced our new Which? Energy Saver logo to our product reviews. 

Our Energy Saver award is given to Best Buy products that meet our own energy-efficiency criteria and is designed to help you choose products that will cost you the least to run compared to other products of the same type that we've tested. 

Below you'll find the criteria we use to decide which products are eligible for a Which? Energy Saver logo. We've chosen dishwashers, kettles, tumble dryers and TVs to receive the award as there are big differences in energy use between different models, meaning you can save money and electricity by choosing a Which? Energy Saver logo award-winning model.

Dishwashers

Best Buy dishwashers with an Energy Saver logo are in the top 10% of all full-sized dishwashers we've tested for energy use on their main program and use 22% less energy than average.

Kettles

Energy Saver Best Buy kettles must achieve at least four stars (less than 0.115kWh) for the energy used to boil one litre of water, be in the top 10% of kettles we’ve tested for low minimum fill, and score at least four stars for the automatic shut-off once the boiling point is reached (less than seven seconds).

Tumble dryers

Best Buy tumble dryers with an Energy Saver logo not only score five stars for running costs in our tests, but are those that significantly exceed what’s required to achieve an official A-rating for energy use. All Energy Saver tumble dryers must use less than 0.3 kWh/kg when drying a full cotton load on a cupboard dry setting.

TVs

Best Buy Energy Saver TVs combine low energy use relative to screen size, along with effective eco-friendly extras – such as ambient light sensor (which adjusts the screen brightness depending on how light the room is) and screen blanking (which blanks the screen when tuned to a digital radio channel). To earn an Energy Saver award, the Best Buy TV must score five stars for optimum picture setting power while in use. This rating is relative to the screen size in our tests, since larger TVs will typically have higher energy use than smaller sets.

Fridges, freezers and fridge freezers

Best Buy cooling appliances are fast at chilling food and keep a constant temperature across all shelves and compartments. To highlight the Best Buys that are the most energy efficient, we've awarded the Energy Saver logo to the 20% that have the lowest running costs, with separate rankings for tall and undercounter fridges, tall, undercounter and chest freezers, and tall and side-by-side American style fridge freezers.

 

The Which? Energy Saver logo is a Which? rating and is not in any way endorsed or associated with official EC labelling laws or regulations. For advice on understanding the official EC energy label on products see our guide energy labels explained.
