Microwave types explained

There are three main types available:

Microwave-only models (solo microwaves)

Sometimes called 'solo' microwaves, these are the most basic. They're great for simple tasks such as warming soup, heating ready meals or defrosting food.

They tend to be cheap and compact, so can be a good option if you just want to complete simple tasks more quickly than in a conventional oven. But they don't brown food, so they're unable to compete with ovens on grilling or roasting meat.

Pros

• Cheapest type
• Good for simple defrosting, heating and reheating  
• Usually less bulky than a combi microwave
• Lots to choose from

Cons

• Limited functionality – you can’t roast or brown food
• Tend to have smaller capacity than a combi

Go to our solo microwave reviews to see all those we've tested.

Combination microwaves

Combination (or combi) microwaves can roast, crisp and brown, just like conventional ovens. 

They tend to be the most expensive type but are also the most flexible. The grill and convection heating (fanned hot air) functions mean they can cook and brown your food, often much more quickly than a conventional oven.  

Pros

• Offer extra cooking options over and above basic microwaving
• Can cook in the same way as a conventional oven
• Can be quicker than using your main oven, especially if you combine cooking modes
• Usually have lots of extra auto functions and features
• Tend to be able to fit more inside than other types of microwave

Cons

• More expensive than other types
• Bulkier than a regular microwave
• A more basic model may suffice if you simply want to heat and defrost food
• Less cooking capacity than a conventional oven

Microwaves with grill

These combine normal microwave cooking with a grilling element. They can perform all the tasks you'd expect from a standard model, such as defrosting ready meals and reheating leftovers. The grill function can also brown food. 

You can use the grill and microwave cooking functions separately or combine them, for example, to brown the top of a shepherd’s pie while microwaving it. They usually come with a metal rack so food is closer to the grill.  

Pros

• Can crisp and brown food, as well as heat and defrost
• Compact – usually the same size as a solo microwave
• Cheaper than a combi model
• Often come with a metal rack so food is closer to the grill

Cons

• Don't offer convection heating, which helps a microwave cook like an oven
• Usually more expensive than a solo model

More options to choose from

All three types of microwave are available as either:

Flatbed or turntable

Flatbed microwaves don't have a traditional turntable and use a different technology to distribute heat evenly.

The big advantage of a flatbed is that you get extra cooking space, as you can squeeze in bulky or oblong containers without having to leave room for them to rotate. The lack of a turntable also means they're less fiddly to clean as there are fewer places for cooking grime to collect.

On average, you'll pay more for a flatbed model, though.

To see which are brilliant at heating evenly, head to our flatbed microwave reviews. 

Freestanding or built-in

Freestanding models sit on your countertop, whereas built-in microwaves slot seamlessly into your kitchen units, for example above your oven. Built-in microwaves are much more expensive than freestanding models.

Best microwave features to consider

Despite their relatively straightforward purpose, microwaves can vary considerably in terms of the accessories and features they offer.

Here are some of the key features to look out for.

• Auto cook programs Enter the type and weight of food, and the microwave will automatically set the time and power needed to cook it. Premium models can offer up to 30 programs, including specialised ones for popcorn or roasts.
• Auto defrost Most microwaves offer an auto-defrost setting that uses bursts of low heat to defrost based on the weight of the food. Some come with settings for specific foods.
• Auto reheat Enter the weight of the food and the microwave automatically calculates how long it should take to reheat. Better microwaves let you select what it is you're cooking, rather than giving one cooking time for every type of food.
• Child lock Some digital models have lockable control panels.
• Clear labelling Controls should be clearly labelled with a large font size. Digital displays should be brightly lit and easy to read. If you're visually impaired, consider one that beeps when you make a selection.
• Clear viewing window Combined with a bright interior light, this makes it easy to check on the food. Watch out for reflective door finishes or window grids that are hard to see through.
• Large door Wide-opening or dropdown doors make it much easier to get heavy or hot dishes in and out of the microwave, especially if you have reduced strength or dexterity. 
• Microwave toastie maker A great alternative if you don't have a toastie maker. Check our ultimate cheese toastie guide to find out how a microwave toaster maker fared with other gadgets.
• Multi-step programming This allows you to program different cooking modes in sequence, to automatically switch between defrosting and cooking your dinner, for example.
• Pizza function This tends to work better with grill or combi microwaves, as the grill helps to crisp the pizza base and brown the top. Some models come with ‘crisper plates’ which can also be used for quiches. You'll get better results if you use a frozen pizza and pre-heat the oven and plate for four or five minutes first.
• Silent mode There is usually a way to silence the myriad of beeps your microwave makes, if they annoy you. It's not always immediately obvious from the controls, so check your instruction manual - or the manufacturer's website, to find out how to turn them off. You might need to press and hold two buttons at once.  
• Touch-panel controls These take far less effort to press than push-button controls. If you do go for button controls, they should be large, easy to press and not too close together.
• Vegetable steamer These can be tricky to get to grips with, but after a bit of practice it's a fast and healthy way to cook vegetables.

What size microwave should I buy?  

Microwaves come in all sizes, ranging from small, compact models to large, bulkier machines that will take up much more space.

Basic microwaves tend to be the smallest; some combis measure almost twice the size of the smallest solo and grill microwaves we’ve tested.

Arguably more important than external size is internal capacity – we've found microwaves of the same size can vary massively in terms of usable space.

While manufacturers do generally state the internal capacity, this doesn't actually tell you what size dishes you'll be able to get inside.

Combis usually have a much bigger capacity than standard machines. The average combi can fit a 35cm-wide dish inside, compared with 29cm for a typical solo model.

Clearance space

All microwaves need some clearance space around them to allow air to ventilate, but the amount needed varies. So consider where yours will be placed and check this before you buy.

Half of those we’ve tested need at least 30cm above them, but we’ve found plenty that only need between 10cm and 20cm.

Many also need 10cm to 20cm space at the back and sides. However, if you’re short on counter space it’s worth looking around as we’ve found some that only need a 5cm gap around them, or none at all.

You can check clearance space for specific models by finding the user manual online or contacting the manufacturer directly.

If you don't have the room for a microwave, our electric grill reviews can help you find a space-saving alternative.

How much does a good microwave cost? 

Don't assume you need to pay the earth to get a decent microwave. 

We’ve found models across all price brackets that offer a good range of features and do what they're meant to do brilliantly. 

Less than £50

Those costing less than £50, from the likes of Asda and Tesco, will be pretty basic. They tend to be on the small size and are likely to be microwave-only (solo) models with limited settings. 

This makes them very easy to use, but you won’t usually get much in the way of auto cook or defrost programs (see features to look out for, below). 

For simple heating and defrosting, cheaper brands can be every bit as good as more expensive options. We've found plenty of great machines starting from just £45.

For around £100

Look for a microwave with a selection of auto programs (to automatically set the weight and time for specific foods), digital displays and easy-to-use push-button or touch panel controls.

Some models at this price will come with other extras such as delayed start and multi-stage cooking (to automatically switch between heating modes such as defrosting and heating).

Cheaper grill and combination microwaves are available for around £100.

For around £200

Features to look for include self-cleaning catalytic linings and pull-down, oven-style doors, which make it easier to take out very hot dishes. Accessories you might find useful include crisper plates and steamer accessories.

For £300-plus

Models at the pricier end of the spectrum are likely to be built-in models. 

If not, they should have standout features, such as one-touch sensor cooking, which works out what's needed for you – all you need to do is put your food in and press the start button – or a built-in steamer.

Are high-powered microwaves better than low-powered?

A microwave's power is measured in watts - and generally, the higher the wattage, the faster your food cooks.

Our tests have shown that a higher wattage isn’t always a good indicator of microwave performance though. We've found 700W microwaves that can cook food as well and as quickly as 1,000W microwaves.

It's worth remembering that not everything needs to be microwaved on full power for the best results. Choosing a solo microwave with adjustable power levels will give you the flexibility to blast on full power for quickly reheating liquids such as soup or to defrost mince gently without cooking it.

Microwave heating categories

A microwave’s heating category is rated from A to E, and will tell you how quickly or slowly your oven will heat food. Microwaves in category E will heat your food more quickly than microwaves rated A. You’ll find your oven’s rating on the front, usually on the door. E is the most common rating.

All the microwaves we've tested have been given a heating category of E by the manufacturer, which means they're supposed to cook at between 741 and 800W, but this isn’t always the case. 

We test the performance of microwaves against their power ratings and have found they’re not always accurate – differences of 5% to 10% are commonplace.

You may need to cook your food for longer than recommended to make sure it’s piping hot all the way through. 

Are microwaves energy efficient?

Microwaves are a good way to cut your energy costs as they use significantly less energy than other cooking appliances.

In a recent test, we compared the energy use of microwaves to electric ovens and air fryers when cooking a jacket potato. We also measured the energy used to steam vegetables, compared to induction hobs and pressure cookers.

Baking a 200g jacket potato

Steaming 300g of broccoli

Based on our test, you save 23p when you choose to cook your jacket potato in the microwave rather than the oven and 6p if you shun your air fryer.

When it comes to steaming, the microwave beat both the induction hob and pressure cooker, saving around 4p for each healthy bowl of veggies.

Microwave energy-saving tips

These tips will help you to save even more money when using your microwave.

Choose the correct power setting for your dish

It can be tempting to whack your microwave’s power up to the highest setting for a quicker dinner. But you don’t need to blast everything on ‘full’.

Cooking certain foods at full power will dry them out or burn the outside before the middle is done. And you’ll use more energy doing so, too.

Based on using an 800W microwave:

• 100% or High Ideal for anything with a high water content and the best setting for steaming. It’s also good for reheating ready-made meals, soups, canned foods, cold coffee and tea, mince or tender meat, poultry, fish, cooked pasta, and most vegetables.
• 70% or Medium High Reheating single-serving leftovers, casseroles, stews, ribs, and foods with cheese. You can also use it to warm milk but be sure to stir it every 15 seconds so you don't end up with a thin film on top.
• 50% or Medium Good for warming dense foods, meals requiring a slower cooking time or that can’t be stirred. You can also use this setting for slow-cooking drier or bigger joints of meats such as ham or pork and whole poultry. 
• 30% or Medium Low Simmer foods such as chilli, sauces, rice and cereal on this setting. You can also use it to defrost smaller items - many microwaves use Medium Low as the ‘auto defrost’ setting.
• 10% or Low The best choice for defrosting large items such as whole poultry and fish, and dense meat. Also good for softening butter or melting chocolate.

If this seems like too much effort, look for a microwave with auto programs that'll set the time and power level for you.

Switch it off at the wall

Although microwaves don't use much electricity when on standby, it still stacks up when left for the whole day. This is especially true for models with digital displays.

Several microwaves we’ve tested, such as the Sharp YC-PG284AU-S and Samsung MS23K3513AK have a power-saving mode which puts the control panel and clock into sleep mode to reduce energy consumption when the unit is not being used for a long time.

If your microwave doesn’t have this feature, we advise flicking the power switch off when you’re not using it.

Keep it clean

Keeping your microwave clean will help to reduce energy costs too because bits of food, grime, and spills will add a couple more seconds to the cooking time of your food.

A good wipe with a cloth soaked in a water and vinegar mixture is enough to keep your microwave spick-and-span when done regularly.

Eco Buy microwaves

You'll save money and reduce your home's environmental impact if you buy an Eco Buy microwave.

These models are proven to be energy efficient and come from brands that stay fault-free for longer, so shouldn't need replacing very often.

Our Eco Buy models are also excellent at the key tasks, scoring 65% and above, so you get the best of both worlds.

Because of these strict criteria, less than 10% of the microwaves we've tested get an Eco Buy recommendation.

How to clean your microwave

To get the best possible results from your microwave, you need to keep it clean.

Little and often is best, as this will prevent food from building up and sticking to the interior. If you've had a spillage, the sooner you deal with it the better. Dried-on messes will be harder to shift.

To remove stubborn food spatters inside your microwave:

• Fill a microwave-safe bowl with water, white vinegar and sliced citrus fruits (lemon, lime or orange) 
• Heat on full power for several minutes, or until the viewing window steams up
• Leave to cool for at least five minutes
• Open the door and wipe down the interior with a clean sponge. 

If your turntable is on the grimy side, simply remove it and wash with warm soapy water – or pop it in the dishwasher if your model permits. 

You can wipe down greasy, smudged viewing windows with a 50/50 mixture of vinegar and water, before rinsing and leaving to air-dry. Your best bet for getting the gunk out of the rubber door seals is a damp cloth dipped in a little bicarbonate of soda. 

Choose the best container for heating and cooking: Can you put glass in the microwave? Plus plastic, foil, paper and more.
