For one saucepan of onion gravy, a portable single-zone induction hob is the more proportionate choice if you need to put it away after cooking. A built-in hob makes more sense if it will serve as your main cooker for multi-pan meals; before choosing either route, check your saucepan’s base and size, and the exact hob’s electrical requirements.
If you usually use one saucepan and want to clear the worktop afterwards, a storable single-zone hob is worth considering. Check its stated pan-size range against your saucepan; Tefal UK specifies a 12–26 cm range for its IH210840.
If softening onions and managing a simmer matter more to you than rapid heating, compare manual settings and controls. Tefal UK lists seven power levels, a timer and pause control for the IH210840; these are features of that model, not every portable hob.
If gravy is only one part of a meal cooked across several pans, a built-in four-zone model may better fit the wider task. Installation differs by model: Bosch GB describes the PUE611BB5B as Plug & Play, while AEG UK specifies a hardwired connection for the TO84IA00FB.
Decide whether this is chiefly a one-pan appliance or a replacement main hob, then check low-heat controls, saucepan fit and installation for the exact model.
| Concern | What to check | Who this matters to |
|---|---|---|
| Compact one-pan cooking | Compare the number of zones and the space needed to use and store the hob. Check the maker’s accepted pan diameter. | With little worktop space, I want to put the hob away after cooking one saucepan. Roughly 46% of consumers put that compact, one-pan need first. |
| Gentle heat control | Look at the manual power settings and whether a timer or pause control would help you manage cooking. | When softening onions and simmering gravy, I want heat I can adjust rather than choosing by maximum power alone. About 36% of consumers prioritise that control. |
| Wider everyday cooking | Check zone count, hob dimensions and the exact installation and electrical instructions. | If I also cook meals across several pans, I need the hob to work as my main cooker. Around 18% of consumers place that wider cooking need first. |
Induction cooking needs a ferromagnetic pan base of a suitable size for the zone. Bosch UK advises matching the base to the cooking zone; Tefal UK specifies 12–26 cm pans for the IH210840.
Check the saucepan’s induction marking or whether its base is ferromagnetic, then compare its base diameter with the exact hob’s stated range.
High-power heating does not replace the ability to adjust heat while onions soften or gravy simmers.
Compare manual settings and the controls you would use during cooking before treating boost power as the deciding feature.
Bosch GB describes the PUE611BB5B as Plug & Play, whereas AEG UK specifies a hardwired-only connection and 7200 W total loading for the TO84IA00FB.
Read the installation instructions for the exact model and check that the proposed kitchen setup is suitable before ordering.
A hardwired installation or an unsuitable worktop cut-out may require additional work.
Electrical Safety First warns that exceeding an extension lead’s current rating can overheat the lead or plug and create a fire risk.
Check the lead’s rating against the combined load of connected appliances, and do not daisy-chain extension leads.
Tefal UK positions the IH210840 Everyday Slim as a portable, single-zone option for small kitchens or an extra cooking zone.
Bosch GB lists the PUE611BB5B as a 60 cm built-in induction hob with four zones and Plug & Play connection.
AEG UK specifies the TO84IA00FB as a larger built-in option for a kitchen planned around multi-pan cooking.
These portable induction hobs relate to the one-saucepan route. Compare their stated controls and pan requirements with your gravy routine, and confirm the plug and electrical suitability of the exact item before buying.

Consider this for a single saucepan if its manual settings and stated pan-size range suit the way you cook gravy.
The product title specifies eight power levels, 60–270°C temperature control, a three-hour timer and suitable cookware from 12–26 cm. Check that your saucepan is induction-compatible and confirm the item’s UK plug and electrical suitability before buying.

Consider this portable option if you want touch controls, but check that its lower settings suit gentle cooking in your saucepan.
The product title specifies 10 power settings, six functions and a safety lock. Confirm the accepted pan diameter, timer availability and UK plug and electrical suitability before buying.
It will need a ferromagnetic base that suits the cooking zone. Bosch UK advises matching the base size to the zone; if you are considering the Tefal IH210840, Tefal UK specifies pans from 12–26 cm in diameter.
Not on power alone: check whether you can adjust the heat for softening onions and simmering. Tefal UK lists seven manual power levels from 300 W to 2100 W for the IH210840, but those settings are specific to that model.
Check the extension lead’s current rating and the combined load before using one. Electrical Safety First warns against exceeding an extension lead’s rating or daisy-chaining leads; its guidance describes a single socket as rated at 13 A, approximately 3000 W.
Not necessarily: a built-in hob needs a suitable kitchen layout, and its connection requirements depend on the exact model. Bosch GB describes the PUE611BB5B as Plug & Play, while AEG UK specifies that the TO84IA00FB is hardwired only; check the installation instructions before choosing.
