Who this choice affects

Families reheating leftovers

If you reheat several cooked portions or use one large serving dish, make room for the plate or dish you actually use. LG UK describes microwaves of 25L and above as family size, though the usable space still needs checking.

Families with limited worktop space

Compare your largest dish with the turntable or internal dimensions, then measure the appliance’s exterior and the space needed to open its door. A smaller stated capacity may suit your worktop, but only if the family’s dishes fit.

Cooks who want a crisp finish

If you also want to brown sweet-potato toppings or use the appliance for other cooking, consider a grill or combination microwave. Smeg UK distinguishes these functions from the straightforward reheating offered by a solo model.

What matters when choosing

Solo microwave

Choose it when: Reheating cooked sweet potato and other leftovers is the main task.

Trade-off: A solo model will not brown or crisp a topping.

Grill or combination microwave

Choose it when: You will also use a grill for browning or convection for oven-style cooking.

Trade-off: Check the appliance’s worktop depth as well as its cavity; Sharp lists its 25L YC-PC254AU-S combination model at 493mm deep.

Concern What to check Who this matters to
Dish and portion space Measure your widest microwave-safe dish and compare it with the turntable or internal dimensions. Check exterior depth and door clearance too. If the family meal goes into one serving dish, I need it to fit and rotate without catching. Around 40% of consumers would put dish fit first.
Thorough reheating Look for adjustable power settings; stir or redistribute food where practical and check that it is steaming hot throughout before serving. With thick portions or food for children, I want to avoid a cool centre rather than rely on an automatic programme. Roughly 40% of consumers would make thorough reheating their main concern.
Browning and other cooking Check whether you will use a grill for browning or convection for oven-style cooking, and whether the appliance fits the available space. If I regularly want a browned topping as well as a hot sweet potato, reheating alone will not give me that finish. About 20% of consumers would prioritise the added cooking functions.

Buying pitfalls

  • Choosing by litres alone

    Capacity does not tell you whether your widest family plate or serving dish will fit. Turntable diameters, cavity shapes and exterior footprints also differ.

    Measure the dish, compare it with the published turntable or internal dimensions, and leave enough space for the door to open.

  • Adding cooking modes you will not use

    A grill addresses browning; convection adds oven-style cooking. Neither is needed simply to warm cooked sweet potato.

    Choose a solo microwave when reheating is the main job. Consider the extra modes only if they match meals you intend to cook.

  • Using an automatic programme as a serving check

    A sensor or preset can help set a reheating cycle, but it does not establish that every part of the food is hot enough to serve.

    Stir or redistribute food where practical and check that it is steaming hot throughout. For children, follow NHS advice to stir microwave-heated food and check its temperature before serving.

  • Leaving disposal until the new appliance arrives

    Replacing a microwave also means arranging what happens to the old electrical appliance.

    GOV.UK’s guidance for UK electrical retailers says they must offer take-back of waste of the same type as an item a customer buys. Ask your retailer how its take-back service works when ordering.

Brands to consider

Panasonic

Panasonic’s UK range includes solo inverter microwaves at different capacities, including models relevant to larger family dishes.

  • Panasonic lists a 32L cavity, 34cm turntable, 1000W inverter power and sensor reheat for the NN-ST65QBBPQ.
  • Its 23L NN-SD27HSBPQ has a smaller stated cavity; check the dimensions of any large family dish rather than assuming it will fit.

Samsung

Samsung’s UK solo range includes the 32L MS32DG4504ATE3 for shoppers considering a larger stated cavity without grill or convection functions.

  • Samsung lists Power Defrost and a Triple Distribution System for this model.
  • Those listed features do not establish how a particular serving dish will fit or replace checking that reheated food is hot throughout.

Sharp

Sharp’s UK range includes both solo and combination models, allowing a choice between straightforward reheating and added cooking functions.

  • Sharp lists a 25L cavity, 900W microwave output and 288mm turntable for the solo YC-MS252AU-S.
  • The grill-and-convection YC-PC254AU-S is listed at 493mm deep, so its worktop fit needs particular attention.

Common questions

What size microwave should I consider for a family meal?

Start with the size of your largest microwave-safe plate or serving dish, not a litre figure alone. LG UK describes 25L and above as family size; compare the dish with a model’s turntable or internal dimensions before choosing.

Do cooked sweet potatoes need a grill microwave?

No: a solo microwave covers straightforward reheating. Consider a grill if you also want a browned topping, or a combination model if you expect to use its additional cooking functions.

How do I check that reheated sweet potato is ready to serve?

Check that it is steaming hot throughout, including the centre of a thick portion. For children’s food, NHS guidance also calls for stirring microwave-heated food and checking its temperature before serving.

Can a retailer take back my old microwave?

When you buy a replacement, ask the retailer about take-back for your old microwave. GOV.UK’s guidance for UK electrical retailers says they must offer to take back electrical waste of the same type as the item purchased; confirm how your retailer arranges the service.
