Start by working out how much fridge and freezer space you actually need, then compare the annual energy consumption in kWh and the energy rating of suitable models. The rating alone does not tell you about capacity or total running costs. A fridge is a good choice if you don’t need a freezer compartment in the appliance, while a fridge-freezer combines both functions. A separate freezer is mainly worth considering if your current setup doesn’t give you enough space. ADEME reminds consumers that choosing an appliance that is too large or buying more equipment than they need can increase energy bills.
If you need both compartments, compare usable capacity in litres, annual energy consumption and the purchase price rather than focusing only on the energy rating. The European Commission explains that the label for refrigeration appliances shows details including the rating, annual energy consumption and capacity.
If you mainly need fridge space and already have enough room for frozen food, check whether an additional freezer compartment would meet a genuine need. ADEME recommends avoiding unnecessary appliances, which can increase energy bills.
If your fridge meets your needs but doesn’t have enough freezer space, compare a more suitable fridge-freezer with a separate freezer, taking into account the space required and the energy consumption of each appliance you use.
Consider this if: you don’t need a freezer compartment in your new appliance, or you already have a separate freezer with enough capacity.
Bear in mind: it won’t freeze food. If you keep using a separate freezer, it will add to your energy consumption.
Consider this if: you regularly use both compartments and want them in a single appliance.
Bear in mind: check the fridge and freezer capacities separately. The total capacity alone doesn’t tell you how the space is divided.
Consider this if: your current fridge meets your needs but you genuinely need more space for frozen food.
Bear in mind: it won’t replace your fridge and you’ll need to make room for it. If both appliances will stay plugged in, compare their annual energy consumption.
| What matters | What to check before you buy | Who should pay closest attention? |
|---|---|---|
| Annual energy consumption | Compare the kWh/year and energy rating on the label for the exact model. If you’re considering two appliances, add together their stated energy consumption. | If I want to keep track of the energy use of an appliance that runs continuously, I compare the kWh/year of models that meet the same needs. Around 30% of consumers put annual energy consumption first. |
| Usable capacity | Check fridge and freezer capacity in litres separately, as well as the external dimensions. | When replacing an appliance, I look for enough space for my usual shopping without paying for capacity I won’t use. Around 30% of consumers prioritise choosing the right capacity. |
| Freezer capacity | Compare the freezer capacity with your actual needs and, if you’re adding another appliance, with the capacity you already have. | If I store lots of frozen food, I check that there’s enough freezer space without adding an unnecessarily large appliance. Around 20% of consumers prioritise this capacity. |
| Installation and maintenance | Check the dimensions and installation type, the noise level shown on the label, and the defrosting system for the exact model. | If I have a specific space in my kitchen, I check the installation requirements and maintenance considerations before choosing. Around 20% of consumers prioritise these practical details. |
The label shows the energy rating, annual consumption and capacity. A model is only suitable if its compartments also meet your needs.
Work out how much space you need for each purpose, then compare the kWh/year of suitable appliances.
A separate freezer doesn’t replace fridge space. If both appliances are in use, their energy consumption adds up.
First check how much extra freezer capacity you need, then add together the kWh/year shown on both labels.
A second appliance takes up space and adds another item that needs to run continuously, as well as the purchase cost.
NoFrost means you don’t need to defrost the models that have this feature manually, but its presence alone doesn’t let you compare the energy consumption of two appliances.
If this feature matters to you, check that it’s included on the exact model and compare the kWh/year separately.
An integrated appliance and a freestanding model are installed differently, and the dimensions must fit the space you have available.
Measure the space and check it against the model’s dimensions and installation instructions before you buy.
Two documented freestanding fridge-freezers let you compare models with the same stated capacities.
The Ksfd1820 and FNd 522i are examples of two separate appliances: a one-door fridge and a freestanding freezer.
The B5RCNE416HG freestanding fridge-freezer is a documented example for households looking for generous fridge and freezer space.
The HDPR1618ANPK freestanding fridge-freezer is an A-rated model presented with connected features.
The ENS3SE18S is an integrated fridge-freezer to consider if your kitchen is designed for this type of installation.
These appliances cater for separate freezer needs and combined fridge-freezer use. Compare their capacities and energy consumption to find the right fit for your setup.

The European label shows details including the A to G energy rating, annual energy consumption in kWh, compartment capacities and noise level. Compare the kWh/year of models with capacities that meet your needs; the QR code links to information about the model in EPREL. This labelling applies to household fridges, freezers and fridge-freezers.
For two options that meet the same need, multiply the kWh/year shown on each label by your electricity rate per kWh, then by the period you have in mind. Add the purchase price and, if you’ll be using two appliances, their respective energy consumption. The result depends on your tariff and actual usage, so it isn’t a guaranteed bill.
Check the dimensions and installation instructions for the exact model. For fridges, Anses recommends checking the temperature regularly and says the ideal storage temperature is between 0 and +4 °C at the coldest point. It also advises against overfilling the appliance, to help air circulate. This is general guidance and not tailored advice.
When a private individual buys from a professional seller, the legal guarantee of conformity allows them to make a claim for two years from the date the goods are delivered, subject to the legal conditions. This is separate from a commercial warranty, which is optional. When a new appliance is sold, free like-for-like take-back applies to an equivalent used appliance. Ask the seller how this works in practice, particularly for delivery.
