Choose according to how much food you keep chilled and how much you freeze. A fridge freezer is suitable when both needs are regular but moderate, while a separate freezer is worth considering if frozen portions consistently fill the bottom of the fridge freezer. Compare the usable capacity of each compartment, the space available, annual energy consumption in kWh/year and temperature-monitoring features. These do not replace suitable storage or checking the coldest area.
You need to distinguish portions to eat over the next few days from those to freeze, without overfilling the chilled compartment. A France 3 Nouvelle-Aquitaine report published in 2026 illustrates the preparation of five meals for four people; Anses highlights the importance of proper storage and air circulation for perishable foods.
The main requirement is a well-organised supply of frozen portions, with drawers and dedicated freezer capacity. Bosch and Electrolux technical specifications show that freezer capacity can vary considerably between a fridge freezer and a single-door freezer.
Capacity, features and stated annual energy consumption should be compared together. ADEME reminds us that fridges and freezers run continuously, and that an appliance that is too large or over-equipped can increase electricity consumption.
Consider it: if you only freeze a few portions and fresh food is your main priority.
Limitation: the compartment may restrict space for containers and make it harder to separate chilled and frozen food.
Consider it: if you regularly alternate between fresh meals and frozen portions but do not have room for two large appliances.
Compromise: the freezer reserve shares the appliance with the fridge compartment.
Consider it: if frozen portions regularly fill the fridge freezer drawers and you need dedicated storage.
Allow for: additional space, a socket and ongoing energy consumption.
| Priority | What to check | Your needs |
|---|---|---|
| Temperature and monitoring | Check the temperature setting, indicator or display; a door or temperature alarm can help with monitoring; leave enough space for air circulation. | I want to identify a cold zone for meat, fish and cooked dishes. Anses recommends monitoring 4 °C in the coldest area, with a range of 0 °C to +4 °C for perishable foods. |
| Usable capacity | Compare fridge and freezer litres separately; check the number and format of the drawers; look at the freezing capacity in kg/24 h if you freeze large batches. | My fresh and frozen portions do not take up the same amount of space. I need to store containers, bags and dishes without choosing based solely on the advertised total capacity. |
| Long-term energy consumption | Compare kWh/year between appliances with similar capacities and configurations; use the A to G energy label as a guide; avoid choosing an oversized appliance. | I am looking for capacity that matches the amount I actually store. ADEME advises taking into account the fact that these appliances run continuously. |
| Freezer maintenance | Check whether the model specifies No Frost or Low Frost; look at how easy the drawers are to see and the internal layout; distinguish reduced frost build-up from complete freedom from defrosting. | If I regularly freeze meals, I want to minimise defrosting while keeping portions easy to find. |
A fridge freezer may look spacious while allocating only a limited amount of room to freezing. Bosch specifications state 103 L of freezer capacity for the KGN39AIAU, compared with 334 L for the GSN36AICM freezer.
List the portions you usually keep chilled and those you freeze, then compare the usable litres of each compartment and the size of the drawers.
Storage, air circulation and temperature control remain important. Anses advises against overloading the fridge and recommends placing perishable foods in the coldest area.
Choose easy-to-read controls and an alarm if it suits the way you use the appliance, arrange food to allow air to circulate and check the temperature in the coldest spot.
A separate appliance runs continuously and also requires a suitable location. ADEME recommends comparing the size and features with your actual needs rather than focusing on capacity alone.
Add a separate freezer when your storage needs justify it, then compare kWh/year, dimensions, noise level and the installation instructions for your chosen model.
A second appliance means continuous electricity consumption and additional space requirements.
Anses states that domestic freezing at -18 °C stops bacterial growth, but most micro-organisms survive it. It recommends freezing food as soon as it is bought or prepared.
Make sure drawers are easy to access for portions that need freezing promptly, label them and do not use the freezer as a last-minute rescue solution.
In France, Bosch offers freestanding fridge freezers and freezers whose specifications detail, depending on the model, usable capacities, energy class, noise level, No Frost system, alarms and internal layouts.
Beko sells fan-assisted fridge freezers, with some models highlighting air circulation, fresh-food compartments and tall formats designed for family storage.
Electrolux offers integrated fridge freezers and freezers designed for fitted kitchens, with specifications detailing capacity, annual energy consumption and installation requirements.
Joybuy fridge freezer options for storing both fresh meals and frozen portions.

Suitable for a household that wants to separate fresh produce from frozen portions in one fridge freezer.
Stated capacities: 187 L fridge capacity and 75 L freezer capacity; three freezer drawers, adjustable shelves, touch controls and stated consumption of 215 kWh/year.
The 75 L freezer may feel limited if portions regularly fill all three drawers. The Low Frost system requires periodic manual defrosting; according to the stated climate range, the appliance is not designed for a garage or outbuilding below 16 °C.

This option is designed for alternating between meals to eat soon and portions to freeze.
Stated settings range from 1 to 7 °C for the fridge and from -15 to -23 °C for the freezer, with a Total No Frost system and B energy class.
Before buying, check the split between fridge and freezer litres, the drawer layout and the annual kWh/year consumption on the full energy label.
Anses recommends monitoring 4 °C in the coldest area and states that the temperature there should be between 0 °C and +4 °C. Locate this area in the manual and check it regularly: a display or electronic setting does not replace this check.
Yes, provided your frozen stock matches the usable freezer capacity and drawer layout. If frozen portions permanently occupy every drawer, a separate freezer provides dedicated storage, but requires additional space and ongoing energy consumption.
It allows you to compare the appliances concerned on a scale from A to G. For two similar formats, also look at annual consumption in kWh/year, separate capacities and noise level, rather than focusing solely on the energy class letter.
No. No Frost is mainly designed to limit frost and reduce maintenance, which can be useful if manual defrosting is off-putting. It does not replace correct settings, temperature checks, proper storage or compliance with recommended storage times.
Check the available space or housing unit, the exact model dimensions, installation type, whether the door can be reversed, the power socket and the installation instructions in the manual. These factors determine whether the appliance can be installed correctly in your kitchen or storage area.
