Replacing a hob with installation constraints
You’ll need to check that the new hob fits the existing cut-out and connection. Legrand says an induction hob needs a suitably rated dedicated circuit.
Who is this option for?
Cooks who want to keep their existing pans
You want to keep using your saucepans and frying pans: Que Choisir points out that cookware used on an induction hob must be compatible with the technology.
Cooks preparing several dishes at once
You’re comparing the number of cooking zones and the space available for your pans, or you’d like to keep cooking with gas. Bosch describes configurations with three or four zones, as well as combinable zones; Electrolux also offers a dual-fuel induction and gas hob.
What to look for
First, check the installation and the cookware you want to keep. Then choose the number and layout of cooking zones to suit the way you usually cook. If you’re replacing a hob in France, the points below highlight the main priorities to consider.
| What to consider | What to check before buying | Who this matters most to |
|---|---|---|
| Installation and fitting | Measure the cut-out and check the connection requirements for the exact model. Legrand recommends a suitably rated dedicated circuit for an induction hob. | I want to avoid finding out after buying that the cut-out or power supply isn’t suitable. Around 27% of consumers prioritise compatibility with their existing installation. |
| Cookware compatibility | Check that the bases of your saucepans and frying pans are compatible with induction, as Que Choisir advises. | I want to keep using the cookware I already own and identify any pieces I’ll need to replace. Around 27% of consumers prioritise keeping their existing cookware. |
| Number of dishes you can cook at once | Compare the number and layout of cooking zones with the pans you use at the same time. | When I’m cooking several dishes at once, I want enough space for my pans. Around 20% of consumers put cooking several dishes simultaneously first. |
| Large cookware | Check the usable dimensions and how the combinable zones work. Bosch says the two CombiZones on the PVQ61CHB1E can be joined to accommodate large cookware. | I cook with a large stockpot or fish kettle and want to make sure it fits on the intended zone. Around 13% of consumers prioritise using large cookware. |
| Keeping gas | For a dual-fuel hob, check both connections and the ventilation requirements. GRDF lists the connection and ventilation among the safety requirements for an indoor gas installation. | I want to keep a flame for certain types of cooking and find out whether a dual-fuel hob suits my installation. Around 13% of consumers prioritise keeping gas burners. |
Mistakes to avoid
-
Choosing by the external width without measuring the cut-out
The overall dimensions and the cut-out dimensions can differ, even for the same model.
Measure the existing opening and compare it with the cut-out dimensions listed for the exact model before buying.
Depending on your home, you may also need to adapt the worktop or arrange a specialist installation.
-
Forgetting about your cookware when switching to induction
Incompatible saucepans and frying pans won’t work on induction zones, which could affect your choice of hob.
Make a list of the cookware you need and check that the bases are compatible before choosing a technology.
-
Assuming a dual-fuel hob means you can skip installation checks
A dual-fuel hob means checking the electrical supply as well as the gas and ventilation safety requirements.
Have the connections and ventilation checked for the model you’re considering, then confirm the layout of the cooking zones in its manual. The overview and detailed specifications for the Electrolux KDI640713K show different layouts.
-
Assuming a combinable zone works with all cookware
A flexible zone won’t make cookware with an unsuitable base compatible with induction.
Check the cookware base and dimensions separately, along with the instructions for using the combined zone.
Brands to know when comparing hobs
Bosch
The models covered here illustrate hobs with three or four cooking zones, as well as an option with combinable zones. These features aren’t available on every hob from the brand.
- Bosch lists three cooking zones for the PUJ61RBB5E, four for the PUE61RBB5E and two CombiZones for the PVQ61CHB1E.
- These are specifications stated by the manufacturer. Check the cut-out dimensions and connections in the manual for the model you choose.
Electrolux
The models covered here offer two different options: a two-zone induction hob and a dual-fuel induction and gas hob.
- The LIT30231C specification sheet gives the model’s cut-out dimensions and maximum power, both useful to check when replacing a hob.
- For the KDI640713K, the overview and detailed specifications show different layouts for the gas and induction zones. Check the configuration in the manual before choosing this model.
Whirlpool
The AKT8090NE-NEW is an example of a four-zone ceramic hob if you’re considering an alternative to induction.
- Whirlpool describes this model as a four-zone ceramic hob.
- This feature alone doesn’t tell you whether the model will fit the cut-out or connection for your old hob.
Hobs on Joybuy
These Joybuy models are built-in induction hobs, including options to compare the number of cooking zones and configurations designed to accommodate several pans.

Frequently asked questions
Will a hob described as ‘60 cm’ fit the cut-out from my old hob?
Not necessarily. Measure the cut-out and compare it with the dimensions for the exact model, as the external width doesn’t tell you the size of the opening. For example, Electrolux gives overall dimensions of 290 × 520 mm and cut-out dimensions of 270 × 490 mm for the LIT30231C two-zone hob.
Can I plug the new hob into an available socket in the kitchen?
Don’t assume so: Legrand says an induction hob needs a suitably rated dedicated circuit. Have the circuit, its protection and the connection required for your chosen model checked before installation. The stated power rating alone isn’t enough to determine how it should be connected.
How should I care for the surface after replacing my hob?
Follow the cleaning instructions in the manual for your chosen model. The Bosch manual for the PUJ...BB.. family has a section on cleaning and care; instructions for another hob aren’t a substitute for those for your model.
Who is responsible for a fault with a new hob bought from a retailer in France?
You should make a claim under the legal guarantee of conformity to the retailer. The French Ministry of the Economy states that you have two years to claim for a new product; a commercial warranty or installation service is separate from this legal right.
What should I check before installing a dual-fuel gas and induction hob?
Check the gas connection, ventilation and electrical circuit. GRDF lists the cooking connection and ventilation among the safety requirements for an indoor gas installation. These checks alone don’t automatically confirm that your home’s installation is suitable.
