Who is this for?

One-bowl reheaters

If beans, soup or leftovers are your main use, a solo microwave keeps the choice focused on reheating rather than grilling or oven-style cooking. Solo models are described as suitable for reheating food and drinks.

Small-worktop buyers

External dimensions matter as much as cavity capacity when counter space is tight. For a concrete reference, the Cookworks 17L model is listed at H24.3 × W44.6 × D32.3cm; check the clearance required by the model you choose as well as its footprint.

Regular plated-meal reheaters

If the microwave will also heat meals on a dinner plate, check the stated plate fit and controls. Swan says its Retro SM22030LGRN 20L digital model accommodates a 10-inch dinner plate; that specification applies to that model, not every 20L microwave.

What matters when choosing?

17L manual solo

Choose it when: You mainly reheat one bowl and prefer to set the time and power with dials.

Accept: The exact cavity and turntable may limit larger plates, and timing is set manually.

20L digital solo

Choose it when: Plated meals and button-led timing will be regular uses alongside heating beans.

Accept: The additional capacity and programmes do not remove the need to stir and check the food.

Concern What to check Who this matters to
One-bowl reheating Check that a microwave-safe bowl fits and rotates freely. Follow the food and appliance instructions, then stir and check that the beans are steaming hot throughout. When I am heating one portion, straightforward controls matter more to me than extra cooking functions. Around 42% of consumers would put simple, thorough reheating first.
Worktop and dish fit Compare the exact model’s outer dimensions and required ventilation clearance with your space; check its turntable against your usual dish. In a small kitchen, I need the microwave to fit without sacrificing the bowl or plate I actually use. Compact fit would be the primary concern for around 33% of consumers.
Wider use and controls Check plate fit and whether the available digital settings match the meals you expect to heat. If plated meals will be a regular task, I would value the extra room and prefer digital timing. Around 25% of consumers would prioritise that wider-use convenience.

What should you avoid overlooking?

  • Buying grill functions for reheating alone

    A grill or combination microwave adds cooking functions, but solo microwaves are identified as suitable for reheating food and drinks.

    Start with a solo model unless grilling, browning or oven-style cooking is also a regular need.

  • Judging fit by litres alone

    Cavity capacity does not tell you whether the appliance fits the counter or whether your dish can turn inside it.

    Measure the worktop and your usual dish, then check the exact model’s external dimensions, turntable size and installation clearance.

  • Using one heating time for every serving

    Appliance power and the amount of food affect timing. GOV.UK advises reheating food until it is steaming hot all the way through.

    Use the food and microwave instructions, stir the beans and check the centre before serving.

  • Leaving disposal of the old microwave until later

    An old microwave needs an appropriate electrical-waste route rather than an assumption that it can go with ordinary household rubbish.

    Ask the retailer about its take-back arrangements or find a suitable electrical recycling collection point.

Brands to consider for this use

  • The listing gives six power levels, a 24.5cm rotating turntable and external dimensions of H24.3 × W44.6 × D32.3cm for this model.

  • Set the time and power yourself, and check the cavity and turntable against any larger dishes you use.

Swan

The Swan Retro SM22030LGRN illustrates a 20L digital option for people who also reheat plated meals.

  • Swan lists 800W output, five power levels, 12 auto-cook presets and room for a 10-inch dinner plate for this model.
  • Its added capacity and presets are optional conveniences for someone who mainly heats one bowl of beans.

Midea MMOP01MZ-BK 20L 700W Manual Solo Microwave, black

Consider this manual solo model if straightforward reheating matters more to you than digital controls.

Hisense H20MOWS4UK 20L 700W Solo Microwave, white

This is a 20L solo option if you want to compare dish fit and settings for reheating.

Swan SM4421WHT 20L 800W Digital Microwave, white

Consider this digital model if timed settings and occasional plated meals matter alongside heating beans.

Hisense H23MOBS5HUK 23L solo microwave in black

Hisense H23MOBS5HUK 23L 800W Solo Microwave, black

Consider the 23L capacity if you also expect to use larger dishes; a single bowl of beans alone does not call for it.

Frequently asked questions

What type of microwave is enough for one person reheating baked beans?

A freestanding solo microwave is a sensible starting point when reheating is the main task. A 17L model can work if your usual bowl fits and rotates freely; check the exact appliance rather than assuming all models with the same capacity have the same dimensions.

How do I check that microwaved beans are hot enough?

Follow the food and microwave instructions, stir the beans and check that they are steaming hot throughout before serving. GOV.UK advises that reheated food should be steaming hot all the way through and should only be reheated once.

Do I need a 20L digital microwave for one serving?

No: the larger capacity and digital settings are more relevant if you also reheat plated meals or prefer those controls. Check the dish fit and settings on the exact model; a preset does not replace stirring and checking the food.

What should I do with an old microwave?

Arrange an appropriate electrical-waste recycling route rather than putting it in ordinary household rubbish. Ask the retailer about its take-back arrangements or check for a suitable local electrical recycling collection point.
