Start with the appliance that runs continuously or is genuinely important in your home, then compare the relevant units for each category: kWh/year for refrigeration, kWh/100 cycles for dishwashers and kWh/cycle for ovens. ADEME reminds us that size, features and frequency of use affect real-world consumption. Repair or maintenance may also be worth considering before replacement.
You may be choosing between a fridge, fridge freezer or freezer and want to reduce continuous energy use without paying for unnecessary capacity or features. Compare kWh/year, usable litres and noise levels between appliances with a similar function. ADEME and the European Commission state that the label for refrigeration appliances includes information such as annual energy consumption and storage volumes.
You want to assess electricity and water costs rather than focusing only on the purchase price. Look at the eco programme’s kWh/100 cycles alongside water use per cycle, capacity, programme duration and noise level. ADEME and the European Commission specify that this information appears on dishwasher energy labels.
If you cook frequently, compare each category using its own measurements: an oven displays kWh/cycle according to the cooking mode, while hobs are not subject to mandatory energy labelling. The European Commission distinguishes between these two comparison frameworks.
First compare appliances within their category, then relate their measurements to your storage needs, actual number of cycles and cooking frequency.
| Priority | What to check | Your needs |
|---|---|---|
| Real impact in daily use | For refrigeration, compare kWh/year between appliances with similar capacities and functions. Consider continuous operation, capacity and added features. | I want to replace the appliance that genuinely has the greatest impact on my household’s daily use, without treating a national average as a guaranteed saving. |
| Comparable units | Refrigeration: kWh/year; dishwasher: kWh/100 cycles for the eco programme; oven: kWh/cycle by cooking mode. Compare a hob by its technology and technical specifications. | I want to avoid directly comparing figures measured according to different reference uses. |
| Suitable capacity | Check the usable refrigeration volume, dishwasher capacity and the features you will actually use. ADEME highlights that size and unnecessary features affect consumption. | My appliance should suit the size of my household and my habits, without paying to power capacity I do not need. |
| Repair before buying | Have the fault and maintenance condition checked. For a repair, confirm parts availability, the quotation and the conditions of the Bonus Réparation with a QualiRépar repairer. | Before replacing an appliance, I want to know whether maintenance or a repair could get it working again. |
ADEME’s scenarios depend on capacity, appliance type and length of use. A larger model or one with additional features may change the expected result.
Use the displayed kWh figure as a starting point, then compare capacity, features and your actual usage frequency before making a decision.
A fridge is expressed in kWh/year, a dishwasher in kWh/100 cycles and an oven in kWh/cycle. Comparing the raw figures can lead you to prioritise the wrong appliance.
First compare models in the same category, then put the measurement into context: continuous operation, number of cycles or cooking frequency.
The European Commission states that hobs are not subject to mandatory energy labelling, unlike ovens.
For a hob, check the technology, technical specifications, installation requirements and compatibility with your kitchen instead.
An apparent fault may be linked to maintenance or a simple problem. ADEME states that in France, one in two appliances taken to an after-sales service is not actually faulty.
Have the problem diagnosed or check relevant maintenance causes before replacing the appliance. Also request a quotation and check whether you qualify for the Bonus Réparation.

For a household of two to three people looking for a medium-sized refrigeration capacity.
Declared consumption of 215 kWh/year; 262 L net capacity, including 187 L of fridge space and 75 L of freezer space.
Energy class E. The Low Frost freezer requires manual defrosting approximately once or twice a year; the appliance is not designed for an ambient temperature below 16 °C.
Image unavailable
For a large household that genuinely needs plenty of chilled and frozen storage space.
444 L net capacity and declared consumption of 289 kWh/year; Total No Frost system and stated noise level of 40 dB.
Energy class E. Check the dimensions, ventilation clearances and door-opening direction before installation.

For replacing the main hob in a kitchen with a compatible built-in space.
Four zones, nine power levels, individual timers and pan detection.
Declared cut-out size of 560 × 490 mm; 220–240 V supply and 32 A rated fuse. Use cookware with a magnetic base.

For a small household, flat or office with a limited amount of washing-up to handle.
Stated capacity of three place settings, dimensions of 49 × 34 × 49 cm and stated water consumption of 2.9 L per cycle.
Check the eco programme’s kWh/100 cycles, programme duration and noise level before comparing it with another dishwasher. A cold-water inlet and waste connection are required.

For a small kitchen or occasional cooking without built-in installation.
One cooking zone, eight temperature and power settings, a timer and automatic pan detection.
220–240 V supply, stated 1.5 m cord and 155 mm heating-zone diameter. This hob requires induction-compatible cookware.
No. For refrigeration, the label includes information such as kWh/year and volumes; for dishwashers, it shows kWh/100 cycles for the eco programme, water use per cycle, capacity and noise; for ovens, it shows kWh/cycle according to the cooking modes. ADEME and the European Commission therefore recommend comparing appliances in the same category and with a similar function first.
No. The European Commission states that there is no energy-labelling requirement for hobs. Instead, compare the technology, available technical information and installation requirements, without inferring consumption from an energy-class letter.
No. ADEME recommends diagnosing the cause of the problem first and states that in France, one in two appliances taken to an after-sales service is not actually faulty. A filter, limescale, a blocked hose or the need to defrost may be responsible. Then weigh up the repair against the appliance’s condition and energy consumption.
Yes, subject to conditions. The Bonus Réparation may apply when an appliance outside its warranty is taken to a QualiRépar repairer and the fault is eligible. ecosystem states that from 1 January 2026, the amounts may vary depending on the appliance. Check whether the fault and repairer are eligible before choosing a replacement.
