Your freezer is one of the few appliances you have plugged in and switched on all the time, so it’s constantly using electricity.
All freezers sold in Britain are required by law to carry an energy label, which rates a model’s efficiency and gives you an indication about which ones cost less to run, as they will reduce your electricity bills.
When we review freezers, we test the energy efficiency of each model. Our tests have found that even models that carry the same energy label can cost varying amounts to run each year.
Top energy-saving freezers
All of the freezers we review are tested and rated for their true energy efficiency. But the best freezers are also able to freeze quickly, keep your food fresher for longer, are quiet to run and easy to use. Below, we reveal freezers we’ve tested that are cheap to run but also came out top in our tough performance tests.
Freezer energy label changes
From 1 March 2021 a new energy label comes into force, which replaces the confusing A+, A++ and A+++ ratings and resets the scale back to A to G. This is designed to reinvigorate the sustainability race for manufacturers by completely emptying the top A-rating to leave room for improvement. At first it will affect washing machines, washer-dryers, dishwashers, refrigerators, lighting and TVs, with other appliances including tumble dryers and ovens remaining the same for now.
The new label for refrigeration (above) states the capacity of chilled and/or frozen compartments in litres and there is also a new measure for noise emissions.
The new ratings will go from A to G and is a clearer reflection of how efficient your appliance is by modern standards. Each label features a QR-code for more product information which links to the product on the manufacturer’s website. Energy consumption is presented either as kWh per year, kWh per 1,000 hours or kWh per 100 cycles, depending on the product group. This is a change from the old label, which was often based on an estimated usage over a year.
