Replacing your hob while keeping your pans
You want to check which pans will still work before choosing a hob type or planning to buy compatible cookware. UFC-Que Choisir says that a magnet sticking to the base is a simple way to check for iron.
Who is this guide for?
Replacing a built-in hob
You need to compare the cut-out and available space with the model’s instructions, then have the connection checked to make sure it’s suitable for your home. Legrand and Bosch Électroménager France provide guidance on connections and appliance dimensions.
Choosing cooking zones to suit your cooking habits
Choose the number and layout of zones to suit the pans you use at the same time. You could also consider a mixed hob if you want to keep gas. Bosch, Beko and Electrolux product listings show a range of layouts, which you should check against the exact model reference.
What should you check before choosing?
Start by checking your cookware and whether installation is feasible, then compare the cooking zones, total cost and energy sources you want to keep. UFC-Que Choisir highlights the need for compatible cookware with induction. A hob’s external dimensions alone won’t confirm that it will fit an existing cut-out.
Induction hob
Consider it if: your cookware has a ferromagnetic base and the hob is suitable for your kitchen.
Weigh up: UFC-Que Choisir generally describes induction as using less energy than ceramic, but costing more to buy. You may also need to replace some of your cookware.
Ceramic hob
Consider it if: you want to keep using cookware that isn’t compatible with induction.
Weigh up: UFC-Que Choisir generally describes ceramic hobs as cheaper to buy than induction, but using more energy. Also bear in mind that the surface retains heat.
Mixed induction and gas hob
Consider it if: you want to use both cooking methods and have cookware suitable for the induction zones.
Weigh up: the installation must meet the requirements of both cooking methods. The documentation for the Electrolux KDI641723K reference gives conflicting information about the layout of the cooking zones.
| Criteria | What to check | Who is this relevant to? |
|---|---|---|
| Cookware compatibility | Check the base of each pan you use and compare its diameter with those of the cooking zones. According to UFC-Que Choisir, a magnet sticking to the base indicates the presence of ferromagnetic material. | I want to keep my pans rather than replace cookware that’s still usable; around 28% of consumers prioritise compatibility with their hob. |
| Cut-out and connection | Measure the cut-out and available space, then compare them with the instructions for the exact model reference. Ask a qualified professional to check the circuit and connection. | I want to replace a built-in hob without assuming the new one will fit the existing space or circuit; nearly 22% of consumers prioritise installation feasibility. |
| Cooking zone layout | Compare the number, diameter and layout of the zones with the pans you use at the same time. Check the controls, timer or flexible zones if these features would be useful to you. | I cook several dishes at once and want the zones to suit my pans; around 22% of consumers put cooking layout first. |
| Total cost | Compare appliance prices on a like-for-like basis and, if necessary, add the cost of compatible cookware and installation. | I want to work out the overall replacement budget, not just the price of the hob; nearly 17% of consumers prioritise total cost. |
| Keeping gas | Confirm that the hob is compatible with your installation and have the connection and positioning checked. Check the instructions for the exact model reference to see how the cooking zones are arranged. | I want to keep cooking with gas while considering induction; around 11% of consumers prioritise keeping this option. |
Mistakes to avoid
-
Choosing induction without checking your pans
UFC-Que Choisir reminds shoppers that cookware without a ferromagnetic base won’t work on an induction zone.
Make a list of the pans you actually use. A magnet sticking to the base is a good first check for compatibility.
-
Relying on the stated width alone
A hob’s external width doesn’t confirm that its cut-out, clearances or connection will suit your installation.
Measure the space, check the instructions for the full model reference and have the installation requirements checked before you order.
-
Assuming a mixed hob will suit any gas installation
Having gas in your home doesn’t necessarily mean the positioning and connection are suitable for the model. Gas appliances and installations in France are subject to safety requirements.
Have your installation assessed and check the cooking zone layout in the instructions for the exact model before choosing this option.
Brands to consider when comparing hobs
Bosch
Worth considering if you’re looking for a three-zone built-in induction hob.
- Bosch Électroménager France’s product listing for the PIJ631HB1E gives three cooking zones and appliance dimensions of 51 × 592 × 522 mm.
- These external dimensions don’t confirm that the model will fit a particular cut-out or installation.
Beko
Worth considering if you’re looking for an induction hob with several zones and a linking function.
- Beko France’s product listing for the HII64206F2MT gives four cooking zones, two Flexizones and a total power of 7 200 W.
- The stated specifications don’t replace checking the installation instructions or comparing cooking performance under the same conditions.
Whirlpool
A useful point of comparison for a four-zone ceramic hob.
- The French product listing for the AKT 8090/NE gives four cooking zones and a timer for each zone.
- Check the exact model reference and built-in dimensions: the advertised width alone doesn’t confirm that it will fit your worktop.
Electrolux
Worth considering if you’re comparing a hob that combines induction and gas.
- The official product listing identifies the KDI641723K as a mixed hob.
- The product listing gives conflicting information about the cooking zone layout. Check the documentation for the exact model reference before comparing its layout with other hobs.

Frequently asked questions
How can I check my pans before switching to induction?
Place a magnet against the base: if it sticks, this indicates the presence of ferromagnetic material. Also check the cookware markings and compare the diameter of the bases with the zones on the hob you’re considering.
Can I plug a built-in induction hob into a standard socket?
Don’t assume you can. According to Legrand, a built-in hob needs a dedicated circuit with suitable protection, unlike a portable induction hob. Ask a qualified professional to check your existing installation and the model’s instructions; don’t alter the circuit yourself.
Will a hob the same width as my old one fit the cut-out?
Not necessarily. Measure the cut-out and available space, then compare them with the dimensions and clearances in the installation instructions for the exact model reference. The external dimensions alone aren’t enough to confirm it will fit.
Can I install a mixed hob simply because my home already has gas?
No. Having gas doesn’t by itself confirm that the connection and positioning are suitable for the model. Have the installation checked and consult the exact model instructions before choosing this option. You’ll also need to take into account the electrical requirements for the induction zones.
Does a ceramic hob stay hot after cooking?
Yes, the surface may remain hot after cooking. Pay attention to the residual heat indicator if there is one, and follow the instructions for using and cleaning your model.
