Precision sauté cooks
If you cook onions slowly and need to lower the heat as they brown, induction’s direct pan heating is worth considering. Your frying pan must have a suitable magnetic base.
Who this choice matters to
Multi-pan dinner-party hosts
If the onion pan stays on the hob while you prepare sauces or sides, count the pans you need at once. Check the size of individual zones as well as any bridge or flex-zone arrangement.
Kitchen upgraders keeping their cookware
Check your existing pans before choosing induction, and check the installation instructions for the exact hob. Bosch GB describes one model as Plug & Play, while AEG UK specifies a different model as hardwired-only.
What to check before choosing
For caramelising onions alongside dinner-party dishes, decide how you want to control the onion pan’s heat, then check space for the other pans and whether the hob fits your cookware and kitchen.
| Concern | What to check | Who this matters to |
|---|---|---|
| Heat control | Try the control layout and check that the onion pan’s base fits a cooking zone; do not choose by Boost alone. | If I am cooking onions slowly, I want to lower the heat when browning begins without relying on rapid initial heating. Around 42% of consumers put controllable sautéing first. |
| Space for other pans | Count simultaneous pans and compare their base sizes with the zones; check for a bridge or flex function if you use large or long cookware. | When the onion pan occupies one zone throughout preparation, I still need places for the other dishes. Enough room for concurrent pans comes first for around 33% of consumers. |
| Cookware and installation | For induction, check pan magnetism and base size. Measure the worktop cut-out and follow the exact model’s electrical requirements. | I want to keep using my pans and avoid choosing a hob that does not suit the planned installation. For around 25% of consumers, compatibility is the primary concern. |
Buying pitfalls
-
Buying induction before checking the frying pan
An induction pan needs a magnetic base that suits the cooking zone; an unsuitable pan may not be detected.
Test your main onion pan with a magnet and compare its flat base diameter with the chosen hob’s zone sizes, as NEFF advises.
You may need to replace an incompatible frying pan.
-
Assuming every induction hob plugs into a socket
Connection requirements differ by model: Bosch GB labels the PUE611BB5B Plug & Play, while AEG UK specifies hardwired connection only for the TO64IA00FB.
Read the exact model’s installation instructions and arrange an appropriate electrical assessment before committing to a hardwired hob.
-
Choosing by Boost power alone
Fast initial heating does not settle how conveniently you can adjust the onion pan during a long sauté or fit other dinner-party pans around it.
Prioritise controls you can use, a zone that fits your frying pan and enough remaining cooking space; treat Boost as a separate convenience.
-
Overlooking residual heat on ceramic glass
A ceramic hob heats elements beneath the glass, which can remain hot after cooking. Which? distinguishes this from induction’s direct heating of the pan.
Pay attention to residual-heat indicators, keep guests and children clear of the hot surface, and let it cool before cleaning.
Relevant brands to consider
Bosch
A reference point if you want to compare a four-zone induction hob with a model-specific plug-in arrangement.
- Bosch GB lists four zones, PowerBoost, Touch Select and Plug & Play for the PUE611BB5B.
- Check the installation instructions for the exact Bosch model; the PUE611BB5B’s connection arrangement does not apply to every induction hob.
NEFF
Relevant when flexible pan placement matters alongside cooking with several pans.
- NEFF lists two flex induction zones, cookware detection, Power Move and a removable TwistPad control for the T56TT60N0.
- NEFF advises using cookware with a magnetic base that matches the cooking-zone size.
AEG
Offers models worth comparing when worktop space and the arrangement of multiple pans affect the choice.
- AEG UK lists DoubleBridge on the 800 mm NIK85M00AZ, allowing cooking zones to be joined for larger cookware.
- Its TO64IA00FB is a different model specified as hardwired-only, with a 7,350 W total loading; confirm dimensions and installation requirements model by model.
Hotpoint
A ceramic-electric option to examine if keeping non-induction pans or using physical controls takes priority.
- Hotpoint lists four zones, six power levels and side dials for the HR 620 R H.
- The ceramic glass can remain hot after cooking; pay attention to the residual-heat indicators.

Frequently asked questions
Is induction or ceramic better for caramelising onions?
Choose induction if direct heating of a compatible pan and prompt heat adjustments matter most to you. Ceramic remains an option if you want to keep non-induction cookware, but its heated glass retains heat after cooking; check the controls and pan size on either hob.
Will my frying pan work on an induction hob?
It needs a magnetic base that suits the cooking zone. Test the base with a magnet, then check its flat base diameter against the chosen hob’s zone specifications, as NEFF advises.
Do all induction hobs need to be hardwired?
No; the connection depends on the model. Bosch GB describes the PUE611BB5B as Plug & Play, whereas AEG UK specifies hardwired connection only for the TO64IA00FB. Read the installation instructions for the exact hob you intend to buy.
What electrical checks matter when replacing a built-in hob?
Check the chosen hob’s installation requirements and have the proposed electrical work assessed for your home. In England, GOV.UK’s Approved Document P addresses electrical safety in dwellings, and GOV.UK says registered competent-person installers can self-certify applicable work. Requirements differ across UK nations, so confirm the rules for your location and project.
Should I check for hob recalls?
Yes, check current recall information for the model before buying or using it. Electrical Safety First directs consumers to the Office for Product Safety and Standards for current recall information.
