What matters when choosing?
Start with a microwave setting you can control and a cavity that fits the vessel you will actually use. Then decide whether the extra cooking functions justify a freestanding combination model or whether a fitted installation is part of your kitchen plans.
Freestanding combination microwave
Choose when: You want to place the appliance on a worktop and use grill or convection functions alongside reheating.
Allow for: The appliance needs worktop space, and its stated capacity does not tell you whether your serving vessel will fit.
Built-in microwave-combination oven
Choose when: An integrated appliance is already part of a fitted-kitchen plan.
Allow for: Cabinet compatibility and installation need checking before purchase; this is not a movable worktop option.
| Concern | What to check | Who this matters to |
| Warming control |
Look for selectable microwave power and controls that let you use short intervals. Check the manual for reheating instructions. |
When custard is already cooked, I want to warm it without leaving one long cycle running, so I can stop, stir and check it. Around 40% of consumers put this control first. |
| Serving-vessel fit |
Measure your jug or bowl, including handles, against the internal space, turntable and door clearance; litres alone cannot establish fit. |
I need to bring a shared serving to the table without discovering that its dish will not go through the microwave door. Vessel fit is the primary concern for around 40% of consumers. |
| Other cooking uses |
Decide which grill or convection functions you will use, then check whether a worktop or built-in installation suits your kitchen. |
If one appliance also needs to cover some oven or grill duties, those functions and its place in the kitchen matter beyond tonight's custard. Around 20% of consumers prioritise that broader use and kitchen fit. |

Common questions
How should I warm already-cooked custard in a combination microwave?
Use the microwave function in short intervals at a suitable lower power setting where available, stirring and checking between intervals. The Food Standards Agency advises stirring or turning food during reheating so it heats evenly and checking that reheated food is steaming hot throughout; follow any more specific custard recipe or pack instructions.
Can a sensor-reheat programme handle custard on its own?
No programme removes the need to pause and check custard. Panasonic describes steam-based sensor reheating on its NN-CD88QSBPQ, while Samsung describes a moisture sensor on its MC28A5125AK/EU; these are manufacturer descriptions of their features, not a guarantee for every custard quantity or container. Stir and check before serving.
Can I warm custard in its serving container?
Yes, if the container is clearly marked microwave-safe, fits with the door closed and is suitable for the heating time. Electrical Safety First advises using only items clearly stated to be microwave-safe; transfer the custard if you cannot establish that the serving container is suitable.
Do I need a built-in microwave for a dinner party?
No. Built-in installation is a kitchen-layout choice, not a requirement for warming a shared custard serving. A freestanding model offers placement flexibility; choose a built-in model only after checking the cabinetry and installation requirements of the exact appliance.
Is a combination microwave worthwhile if I only reheat food?
Compare a solo microwave if reheating is your only planned use. A combination model makes more sense when you will also use its grill or fan-assisted oven functions; Sage Appliances identifies those as functions that distinguish combination microwaves from basic reheating models.
