Choose the hob layout and electrical connection before comparing extra functions. For custard, look for adjustable low-power controls and a suitable magnetic saucepan, then check that the hob fits your worktop and electrical supply. A narrow two-zone model leaves more room for preparation but limits simultaneous cooking; a four-zone model offers more pan space, while plug-in and hardwired versions have different installation requirements. Whichever you choose, custard still needs stirring and attention.
If you regularly make stirred custard or sauces, clear power adjustments and a saucepan suited to the cooking zone matter more to your routine than a fast-boil setting. A timer or pause function can be useful, but neither replaces watching and stirring the pan.
You need enough zones for your usual pans without losing too much preparation space. Compare the hob’s outer dimensions with its required worktop opening: a two-zone model is not necessarily narrow, and a four-zone model still needs a suitable cabinet and cut-out.
You may prefer a built-in model designed for a suitable 13A socket, or you may already have provision for a hardwired hob. Check the exact model’s installation instructions and have the circuit and fitting requirements assessed where needed.
Start with the space and electrical connection your kitchen can accommodate, then compare the controls you will use while cooking custard. A 59cm two-zone hob and a narrow two-zone hob solve different space problems, so check dimensions rather than zone count alone.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle heat for custard | Check how you adjust ordinary power levels and whether the model has a timer or pause function. Do not use a boost setting as a substitute for assessing low-heat controls. | When I stir custard, I want to reduce the heat promptly without losing track of the pan. Controllable heat would be the primary concern for around 37% of consumers. |
| Footprint and zones | Compare outer dimensions, the required cut-out and the number of pans you normally use together; two-zone models are not all the same width. | If I need worktop room for preparation, I have to weigh a narrower hob against cooking with fewer pans at once. Around 27% of consumers would put space and layout first. |
| Electrical installation | Check the model’s connection type and installation instructions against your socket or circuit, as well as the required cut-out and clearances. | Before choosing cooking features, I need to know whether the hob can be fitted with my kitchen’s electrical arrangement. Installation would come first for around 27% of consumers. |
| Cookware and everyday safety | Check that the saucepan has a magnetic base and look up residual-heat indication, child lock and automatic switch-off on the exact model. | I want to keep using my custard saucepan and know which safety controls the hob actually has. Cookware and everyday safety would be the primary concern for around 9% of consumers. |
Boost is intended for rapid heating, whereas stirred custard calls for manageable heat changes and continued attention. A prominent boost feature does not establish how a model behaves at the lower settings you prefer.
Check the manual for ordinary power adjustments, timer and pause behaviour. Treat any sensor function as a model-specific aid, not a guarantee against curdling or scorching.
A hob’s outer dimensions do not tell you the size of the opening it needs. AEG specifies its IBK64200CB at 590 × 520 mm externally but gives a 560 × 490 mm built-in opening; that model is hardwired only.
Measure the existing opening and compare cabinet clearances with the exact installation sheet. Check the electrical connection separately.
A mismatch may mean worktop alteration or electrical installation work.
Induction requires a saucepan with a magnetic base. A pan that does not meet that requirement may not activate the cooking zone.
Test the base with a magnet or check the cookware maker’s induction-compatibility information, then compare the base size with the intended zone.
You may need a different saucepan if your existing one is incompatible.
The Office for Product Safety and Standards reported a serious fire risk for one identified portable induction cooker in 2025 because its plug lacked a conforming BS 1362 fuse link. That report does not apply to portable cookers generally.
Check the full model identity, seller and plug information for the cooker you intend to buy. Do not use a cooker if its plug or socket shows signs of damage or overheating.
Bosch offers different formats to compare, including 30cm domino and 60cm induction hobs in its UK range.
IKEA’s 59cm examples include the four-zone VILSTA and two-zone MATMÄSSIG, illustrating why zone count alone does not establish how much worktop width you save.
AEG describes compact two-zone options alongside larger induction models; its IBK64200CB is a documented four-zone example.
These choices include built-in two-zone and four-zone hobs, plus a portable countertop cooker. Compare each one with the space, cookware and electrical arrangement you plan to use; the portable cooker is a different option from replacing a built-in hob.

Consider this built-in format if worktop width is tight and two simultaneous pans are enough. The product name specifies touch controls, nine power levels, a timer and a child safety lock; check the required cut-out, clearances and electrical connection against the installation instructions before ordering.
No image available
This built-in four-zone option is worth considering if you cook custard alongside other pans and have room for a 60cm hob. Confirm the worktop opening, ventilation and electrical connection in its installation instructions; four zones do not establish how the hob performs at low heat.
No image available
Consider this built-in option when you need space for several pans. Its product name specifies touch controls, nine power levels and a booster; assess the ordinary settings for custard rather than choosing it for the booster alone. Check fit and electrical requirements for this exact model.
No image available
This four-zone built-in model suits consideration where a hardwired installation is practical and you often use other pans alongside custard. Its product name identifies it as hardwired; check the required cut-out and have the electrical requirements assessed before purchase.

A portable countertop cooker is a different choice if you do not want a built-in hob. The product name specifies 2000 W, eight power levels, a 60–270°C setting range, a three-hour timer and cookware sized 12–26cm; these settings do not establish custard-cooking accuracy. Check the available counter space and the plug, socket and circuit requirements.
Yes, if you use a magnetic-base saucepan and can adjust the hob’s heat to suit your cooking. Keep stirring and watching the custard as it thickens; a timer, pause function or sensor does not make it an unattended task.
Two zones can be enough if you usually make custard with no more than one other pan in use. If you regularly cook several dishes together, consider four zones, provided the worktop opening and electrical installation suit the model. Check the actual width: IKEA’s two-zone MATMÄSSIG, for example, is a 59cm hob.
Only if that exact hob is designed for a plug-in connection and your socket and circuit meet its installation instructions. Bosch identifies the PUG61RAA5B as Plug & Play, and Joybuy describes that model with a 13A plug and 3.0 kW maximum connected load. AEG specifies the IBK64200CB as hardwired only, so the connection cannot be assumed from the hob’s size.
It will need a magnetic base. Test the base with a magnet or check the cookware maker’s induction-compatibility information, and make sure its base suits the cooking zone you intend to use.
Check the model’s cut-out, clearances and electrical requirements with a qualified installer before altering the worktop or circuit. In England, Approved Document P gives guidance on electrical safety in dwellings, including when work needs notification. Requirements can differ elsewhere in the UK, so confirm the rules that apply where the hob will be installed.
