Slow-cook control seekers
If you caramelise onions regularly, you may value controls that let you adjust the heat as they soften and colour. Check the controls on the particular model rather than choosing by its maximum power alone.
Who is choosing this hob?
Large-batch onion cooks
If you use a wide or elongated pan, compare its base with the available cooking area. A bridge or flex zone may matter more to you than the hob’s total number of zones.
Low-disruption kitchen upgraders
If you are replacing a built-in hob, the connection method and worktop opening may determine which models fit your kitchen. Plug-in and hardwired models need different checks.
What matters when buying?
Start with the pan you use for onions and the controls you want during a long cook, then check the electrical connection and worktop opening.
| Concern | What to check | Who this matters to |
|---|---|---|
| Adjustable heat | Compare the selectable power levels and how you change them during cooking; check model-specific frying assistance only if you would use it. | When onions begin to colour, I want to adjust the heat without relying on a simple high-or-low choice. Around 42% of consumers put that control first. |
| Installation fit | Confirm whether the exact model is plug-in or hardwired, then check its electrical requirements and required worktop opening. | Replacing an existing hob should not mean choosing a connection or cut-out my kitchen cannot accommodate. For around 33% of consumers, installation fit is the primary concern. |
| Usable pan area | Check the pan’s magnetic base against the zone size; consider bridge or flex capability for larger or longer cookware. | I cook bigger batches in a wide pan and need enough usable cooking area beneath it. That pan fit comes first for around 25% of consumers. |
Mistakes to avoid
-
Assuming your current frying pan will work on induction
Induction needs a ferromagnetic pan base. Bosch UK also advises matching the cookware base to the cooking zone for even heating.
Check your intended onion pan for induction compatibility and compare its magnetic base diameter with the hob’s zone guidance.
A non-magnetic pan may need replacing before you can use the hob.
-
Treating every induction hob as plug-in
Connection requirements differ by model: the Bosch PUG61RAA5B is supplied with a 13A plug, while AEG UK specifies its TO64IB00FB as hardwired only.
Check the exact model’s installation instructions, connected load and worktop opening. Have a competent installer assess electrical work.
A hardwired replacement may also involve electrical or worktop alterations.
-
Choosing bridge or flex zones for a single conventional pan
Bridge and flex areas address larger pans or more flexible placement. They do not, by themselves, improve the result when your usual pan already fits one zone.
Compare your pan with the zone layout first; for a conventional pan, give the controls and installation fit greater attention.
-
Leaving onion residue and oil splashes on the surface
Electrical Safety First warns that accumulated food debris and fat can pose a fire risk.
Clear spillages promptly, following the hob manufacturer’s instructions for cleaning its glass surface safely.
Brands to consider for these hob layouts
Bosch
Bosch is relevant if you are considering a conventional-pan layout and need to distinguish a plug-in model from other installation routes.
- The Joybuy listing for the PUG61RAA5B identifies four zones, a 3.0 kW maximum connected load and a supplied 13A plug.
- Do not assume another Bosch model has the same connection method. Bosch UK also advises using ferromagnetic cookware with a base suited to the zone.
AEG
AEG’s TO64IB00FB is a 60 cm option to examine if you frequently use a larger pan for onions.
- AEG UK states that its Bridge function joins two cooking zones.
- This particular model is hardwired only, with a stated 7,200 W total loading and a required 560 × 490 mm built-in opening. A joined area offers little benefit if your pan already suits one zone.
NEFF
NEFF’s T69YYV4C0 is relevant where the kitchen can accommodate a larger hob and flexible pan placement matters.
- NEFF describes two flex zones and a frying sensor on this model.
- Its stated width is 934 mm, so it is not a like-for-like 60 cm replacement. The manufacturer-described sensor assists with temperature monitoring; it does not guarantee how onions will turn out.
Induction hobs for different kitchen layouts
These Joybuy choices include a compact two-zone hob, conventional four-zone layouts and a wider bridge-equipped model. Match your onion pan to a suitable zone and check the installation requirements for the model you choose.

This built-in four-zone layout is a conventional-pan option for onion cooking. Check your pan’s magnetic base against a suitable zone, and confirm the required worktop opening and electrical connection before ordering.
Common questions
Will I need new pans for an induction hob?
You will need a different pan if your current one lacks an induction-compatible magnetic base. Bosch UK advises using ferromagnetic cookware and matching the base to the cooking zone; check the pan you intend to use for onions before choosing a hob.
Can I choose a plug-in induction hob instead of a hardwired one?
Yes, if the particular plug-in model suits your kitchen’s electrical provision and installation requirements. The Bosch PUG61RAA5B listing specifies a supplied 13A plug and a 3.0 kW maximum connected load, whereas AEG UK specifies the TO64IB00FB as hardwired only; check the instructions for the model you intend to buy.
Will a bridge zone help me caramelise onions?
A bridge zone helps accommodate a larger or longer pan; it does not by itself change how onions caramelise. AEG UK says the TO64IB00FB joins two zones, but if your induction-compatible frying pan already fits one zone, focus on its fit and the hob’s heat controls.
How should I clean the hob after cooking onions?
Clear spillages promptly and follow your hob manufacturer’s instructions for the glass surface. Electrical Safety First warns that a build-up of food debris and fat can pose a fire risk.
