If you mainly warm custard, choose a combination microwave only if you will also use its grill or convection cooking functions; a solo microwave can cover basic reheating. For a combination model, prioritise selectable microwave power and manual timing, then check its external dimensions and required clearances against your worktop. A larger cavity or extra cooking modes are worthwhile only if you have room for them and expect to use them.
Who needs which features?
Small-kitchen cooks focused on reheating
If custard and other small portions are your main use, look for selectable microwave power and timing you can set yourself. Measure the space available before choosing a combination model over a solo microwave.
Cooks replacing occasional oven use
If you also want to grill or use convection cooking for small dishes, a combination microwave brings those functions into one appliance. Check that its exterior, door movement and required clearances suit the intended position.
Households using several cooking modes
If air frying, grilling and convection cooking will be regular tasks, additional modes may be useful. Give the appliance’s worktop requirements as much attention as its list of functions.
What matters when choosing?
Start with the microwave controls needed for small portions, then measure the available worktop space. Consider additional cooking modes after those two checks.
| Concern |
What to check |
Who this matters to |
| Controlled warming |
Look for selectable microwave power and manual timing. Follow the custard packaging or recipe instructions for your portion and appliance. |
If I mainly warm small portions of custard, I want control over power and time rather than relying on an automatic programme. Around 33% of consumers put controlled warming first. |
| Worktop fit |
Measure width, depth and height, then check door-opening space and the exact model’s clearance instructions. |
When preparation space is tight, I need the appliance to fit without crowding the counter. Worktop fit comes first for around 42% of consumers. |
| Additional cooking modes |
Decide whether you will regularly use the grill, convection or air-fry functions, and check the controls those modes require. |
If I also cook small dishes without using the main oven, I may accept more controls and a larger appliance. Around 25% of consumers prioritise those additional functions. |
Buying pitfalls
-
Choosing by litre capacity alone
Capacity does not tell you whether a microwave fits a narrow or shallow counter. Russell Hobbs lists its 23L RHM2366B at 469mm wide and 415mm deep; Panasonic lists its 27L NN-CT55 at 520mm wide and 395mm deep.
Measure the dimension that limits your space, then check door movement and the model manual’s placement clearances.
-
Choosing extra modes for a reheating task
Air frying and connected controls do not replace microwave power selection when warming custard. They matter more if you will use them for other cooking tasks.
Decide which modes you expect to use regularly before accepting a larger appliance or more controls.
A larger exterior can take worktop space needed for food preparation.
-
Applying a brand’s test claim to every kitchen
Panasonic’s energy and cooking-time comparisons come from its own tests against specified ovens and dishes; they do not establish the result for every recipe or competing model.
Use the exact model’s dimensions, settings and instructions to assess how it fits your cooking needs.
Brands to consider for these needs
Panasonic
The NN-CT55 is a 27L combination model for buyers considering microwave, grill and convection cooking on a restricted worktop.
- Panasonic lists five microwave power settings, a 1300W quartz grill and convection settings from 100–220°C for the NN-CT55.
- Its listed 520mm width still needs checking against the intended position; a slimline description cannot establish that it will fit.
Russell Hobbs
The freestanding RHM2366B combines a 23L microwave with grill and true fan-assisted oven functions.
- Russell Hobbs lists 900W microwave output, five power levels and a 469mm exterior width for this model.
- Its listed 415mm depth requires a separate fit check, particularly where the counter is shallow.
Samsung
The 32L MC32DG7646CKE3 is aimed at buyers who expect to use microwave, grill, convection and air-fry functions.
- Samsung lists several cooking modes and optional connected controls for this model.
- Check its exterior dimensions against the available space. Samsung says the applicable SmartThings features require Wi-Fi, a Samsung account and the SmartThings app.

Common questions
Do I need a combination microwave just to warm custard?
No. A solo microwave can handle basic reheating; choose a combination microwave if you will also use grill or convection cooking. Which? describes those cooking functions as the distinction from regular microwave cooking.
What should I measure in a small kitchen?
Measure the available width, depth and height, allow room for the door to open, and check the exact model manual for placement and ventilation clearances. Litre capacity is not a substitute for exterior measurements.
Does higher microwave wattage mean better custard warming?
Not on its own. Panasonic lists five microwave power settings for its 1000W NN-CT55, while Russell Hobbs lists five for its 900W RHM2366B. Select settings appropriate to the food and follow the packaging or recipe instructions for your portion and appliance.
What do Samsung’s smart microwave controls require?
Samsung says the applicable Smart Control and SmartThings features on the MC32DG7646CKE3 require Wi-Fi, a Samsung account and the SmartThings app. Check those requirements if connected controls are a reason for choosing the model.
