It heats up your leftovers and your cold cups of tea and pings to let you know when it’s finished. For most of us, that’s all we know about the box lurking on our kitchen counter. But of course, there's more to it than that. Read on to find out which kind of microwave is right for you.


The higher your microwave’s wattage, the faster it can cook food. That’s the key point to know. While more watts equal more power, they also mean a higher price tag.

So, how low can you go? 320-500-watt microwaves are considered to be very low power. They’re for use in caravans and other generator-powered set-ups. You won’t want one of those in your home.

If price is everything, you can probably get a 700-watt microwave for £50. However, this wouldn’t be our recommendation as it’ll be basic and slow, and as low-wattage microwaves don’t distribute heat as efficiently as more powerful alternatives, you’ll need to put time and effort into getting evenly cooked food.

A 1,000-watt microwave should represent both a quality appliance and a reasonable price point. With a bit of luck and a good deal, you should be able to get one for little more than a 700-watt model.

A 1,200-watt microwave would be among the highest-powered for home use. On the top end of the scale, a 1,850-watt microwave would be better suited to a commercial environment.

Microwave wattage and size tend to go hand in hand, so a 1,000-watt microwave is going to be a reasonable standard size.

Types of microwave


It only microwaves, nothing more. This used to be standard, but combinations and microwaves with grills are growing in popularity. Still, a regular solo microwave will do you nicely if you only want to use it to defrost and reheat.  

We haven’t tested it but Currys PC World has a deal on the Kenwood K25MMS14 solo microwave in silver. It's down from £170 to £74.99. 

Combination microwaves

A combination microwave uses a mix of microwave cooking, steaming, a grill and convection heating (circulated hot air) to cook your food. This means that it can roast, crisp and brown dishes like a conventional oven. You can use the functions separately, or at once.

Fans of combination microwaves say they save time and power (no need to fire up the big oven just for a jacket potato), while delivering oven-quality food.

The best combination microwaves come with multi-step programming, which uses the microwave, convection and grill functions in stages to cook food perfectly. They can handle much more complicated recipes than your average heated-up-soup, like flans, meringues, cakes and pies. The steam function is also useful if healthy cooking is a priority for you.

On the downside, they are more expensive than a regular microwave and likely to take up more space.

Again, we haven't tested it but Amazon has a deal on the Samsung MC28H5013AS/EU 28L combination microwave. It's down from £189.99 to £139 - a saving of £50.99. 

Grill microwaves

This is exactly what you’d expect, combining microwaving and grilling functions. You can use the cooking methods together, or one at a time.

Currys PC World is selling the Kenwood K30GMS18 compact microwave with grill for £99, down from £199. We haven’t tested it but we like the price.


As with a convection device, a microwave with an inverter instead of an electric coil or transformer is likely to be more expensive. However, it delivers an uninterrupted flow of power, using less energy and distributing heat more efficiently for even cooking. This means you can use lower heat settings, which will preserve the texture and flavour of food.  

John Lewis has a deal on the Panasonic NN-DF386MBPQ combination microwave with inverter technology. It's on for £209, down from £259. Again, we haven't tested it ourselves.

Location, location, location


A countertop microwave is the standard. What you lose in counter space, you make up for in simplicity. There’s no need to install it – just unbox it and plug it in.

With the caveat that we haven't tested it, John Lewis is selling the Panasonic NN-CS894SBPQ combination steam microwave oven in a stainless steel finish, for £459, down from £509. 


Over-the-range microwaves take the place of range hoods, removing fumes, steam, smoke and heat from the air. They have a light and a fan built into the base. They are generally more expensive than a countertop model and will probably require a professional installation.


If you can bring yourself to remove the cabinet full of old takeaway containers and ramekins, you might free up enough space for an inbuilt microwave.

While it’s advisable to get a professional installer, if you consider the microwave’s venting needs, you can buy a trim kit and do it yourself. As well as saving counter space, an inbuilt microwave gives a kitchen a high-end look.  

We haven’t tested it but My Appliances has a very reasonably priced built-in microwave, the ART28604 20 litre, with a grill as well. It’s on for £105, down from £129.99.

Functions and accessories

Flatbed or turntable?

A flatbed microwave has two key advantages over a turntable: you can use more of its internal space as you can fit in rectangular or oval dishes without giving them space to rotate, and it’s easier to clean. However, if the flatbed comes with a grill, this can cancel out the easy-clean aspect as the grill can apparently be a bit fiddly.

The only real disadvantage of a flatbed is price.

Appliances Direct has a good deal on a Hotpoint MWH2622MB 25L 800W flatbed microwave with grill. We haven’t tested it but it’s on sale for £139.97, a saving of £45.

Auto-cook functions

Most microwaves will have some auto-cook functions. You're most likely to see the auto-defrost or auto-reheat options. Simply input the weight of your food and your microwave will choose the best programme to prepare it.

Higher end models won’t even require you to enter your food’s weight, instead analysing the steam to calculate power and cooking time.

Combination microwaves also offer auto-cook programmes that choose the correct combination of microwave, convection and grill, for more complicated recipes or to defrost, cook and brown a dish. Newer microwaves may even have a pizza function! 

Currys PC World has a great deal on the Kenwood K20MSS15 solo microwave, which has eight auto cooking programmes. It’s on sale for a bargain £64.99, down from £140 – over 50% off. Bear in mind that we haven’t tested it.

Heating categories

A microwave’s heating capacity is rated from A to E, with E heating food most quickly. Your microwave’s rating will probably be shown on its door. E is the most common rating.


Some microwave manufacturers advertise accessories as a selling point, including steamers for rice and veg, and crisper plates to save pies and pizzas from soggy bases.

In our opinion, when buying a microwave, ignore the lure of extras. It's best to focus on the quality of the microwave itself and on getting the best deal possible. Cooking accessories tend to be inexpensive and easy to find.
