To keep energy use down on an appliance that runs all year round, start by choosing the type of appliance and the amount of fridge and freezer space you need. Then compare the kWh/year of models with a similar type and capacity. A fridge-freezer combines fresh and frozen food storage in one appliance; a fridge is suitable if you have little need for freezer space, while a separate freezer provides extra frozen food storage without replacing your fridge.
If your priority is the energy use of an appliance that runs constantly, compare the kWh/year of models of the same type and with a similar capacity, rather than looking at the energy efficiency class alone.
If you want one appliance for both, check the fridge and freezer capacities separately: the total capacity doesn’t tell you how the space is divided.
A separate freezer can provide extra space for frozen food if you already have enough storage for fresh food. However, it adds another appliance that runs constantly.
Consider it if: you mainly store fresh food and need little space for frozen food.
Limitation: freezer space may be limited or unavailable, depending on the model.
Consider it if: you regularly store fresh and frozen food in one appliance.
Limitation: even a suitable total capacity may leave too little space in one of the two compartments.
Consider it if: your main need is extra freezer capacity and you already have enough space for fresh food.
Limitation: it won’t replace a fridge and uses electricity continuously.
To compare appliances that suit your needs, check the kWh/year and the capacity of each compartment on the energy label. ADEME points out that fridges and freezers run continuously, and that size and usage also affect energy consumption.
| What matters to you | What to check | Who this is for |
|---|---|---|
| Energy use and usable capacity | Compare the kWh/year and capacity in litres of appliances of the same type and with a similar capacity. | If I’m replacing an appliance that runs day and night, I want enough space without choosing a capacity I won’t use. Around 42% of consumers prioritise this balance between energy use and capacity. |
| Space for fresh and frozen food | For a fridge-freezer, check the fridge and freezer capacities in litres separately. | I regularly buy both fresh and frozen food, so I’m looking for one appliance with two compartments that suit my habits. This is the priority for around 33% of consumers. |
| Dedicated freezer capacity | Check the freezer capacity in litres, the space it will take up and the kWh/year of the freezer you’re considering. | I already have enough space for fresh food, but need more room for frozen food. For around 25% of consumers, extra freezer capacity comes before other criteria. |
Appliances in different categories or with different capacities don’t offer the same performance. The rating alone can’t tell you whether their energy use suits your needs.
For your final comparison, look at models of the same type and with a similar usable capacity, then check their kWh/year and the capacity of each compartment in litres.
A large total capacity can hide an unsuitable split if you use much more fridge space than freezer space, or vice versa.
Work out how much space you need for each before comparing the separate capacities listed for the models.
According to Liebherr, NoFrost limits frost build-up. However, this feature alone doesn’t tell you what capacity you need or a model’s kWh/year.
Choose the right type and capacity first, then compare the features and energy use of similar models.
Usable capacity doesn’t guarantee that an appliance will fit in your kitchen or that its door will open properly.
Measure the available height, width and depth, then check these against the appliance dimensions and the clearances required for your chosen model.
Bosch’s fridge-freezer range includes different formats for storing fresh and frozen food in one appliance.
Electrolux freezers are worth considering if you want to compare dedicated freezer capacities and different cooling systems.
Liebherr’s freezer range may suit households looking for dedicated storage for frozen food.
These fridge-freezers are designed for storing fresh and frozen food in one appliance. Check the capacity, then review the energy label and dimensions of your chosen model before buying.

Worth considering if you want to store fresh and frozen food in one appliance.
Advertised total capacity of 467 l; Total No Frost and energy efficiency class E. Check how the capacity is divided between the compartments and how much space is needed for installation.

This fridge-freezer may suit you if you’re looking for one appliance for fresh and frozen food.
Advertised total capacity of 360 l; Total No Frost and energy efficiency class E. Check the capacity of each compartment and the clearance needed for installation.

Worth considering if you’re looking for a multi-door appliance for both fresh and frozen food.
Advertised total capacity of 495 l and energy efficiency class E. Before ordering, check the compartment layout, dimensions and any water connection requirements for the dispenser.

This fridge-freezer is worth considering if you’re looking for an advertised total capacity of 444 l for fresh and frozen food.
The product name mentions frost-free operation, 40 dB and energy efficiency class E. Check the capacity of each compartment in litres and the full dimensions to see whether it suits your needs.

Worth considering if a stated width of 54 cm is important when choosing a fridge-freezer for fresh and frozen food.
The model name lists 153 l of fridge capacity, 74 l of freezer capacity, Low Frost and energy efficiency class E. Check the kWh/year, height, depth and required clearances; Low Frost doesn’t mean you’ll never need to defrost it.
Compare annual energy use in kWh, the capacity in litres of the relevant compartments and the noise level in dB(A). The information in the European Commission’s public EPREL database distinguishes between fridge and freezer capacities, among other things. So, when checking the kWh/year, take the type of appliance and the space you need into account.
No. Also compare their annual energy use and usable capacity when they meet the same needs. ADEME points out that the size and use of an appliance affect the energy consumption of a fridge or freezer.
Don’t assume so: Liebherr describes No Frost as a way to limit frost build-up. To compare energy use, check the kWh/year of models with a similar format and capacity.
European Commission Delegated Regulation (EU) 2019/2016 sets out labelling requirements for mains-powered electric refrigeration appliances with a volume greater than 10 l and less than or equal to 1,500 l. When choosing a model sold in France, compare the information on its energy label with its product listing.
