Asda microwaves are cheap, but are they worth buying?

We all like a bargain, yet some of us are reluctant to pluck a cheap microwave from a supermarket shelf when the time comes to buy a new one.

Perhaps you feel there’s a minimum amount you should spend to guarantee a good microwave, or maybe you’re worried that unbranded appliances won’t last.

We’ve tested cheap Asda microwaves, as well as models from Argos, Ikea and Wilko that cost less than £50, to find out whether low-cost microwaves are worth considering.

Keep reading to get our verdict on budget microwaves – and to discover what extra features you can get if you’re willing to spend more.

Four reasons to buy an Asda microwave

Asda might not be the first place you think of when your microwave packs it in, but you could save yourself a trip by getting your groceries and a new microwave at the same time.

And convenience isn’t the only reason to consider an Asda microwave:

1. Asda microwaves are cheap

Asda microwaves typically cost less than £50, with some models available for just £30.

To put that into perspective, the average price of a solo microwave is around £90 – think of what else you could afford to put in your shopping trolley with the money saved.

2. Asda microwaves look good

Cheap microwaves don’t need to be drab, as the Asda GMM101WB-20 (above) proves.

With a glossy black finish and a wooden handle and dials, it wouldn’t look out of place in a modern kitchen, which is more than can be said for some much pricier models.

3. Spending more doesn’t guarantee a good microwave

You don’t have to break the bank to get a good microwave – and paying more doesn’t always mean you’ll get a better product.

In fact, there are as many Best Buy solo microwaves that cost less than £60 as there are Best Buy solo microwaves costing more than £60.

Check out our list of the cheapest Best Buy microwaves for the top bargains.

4. Some cheap Asda microwaves are twice as good as branded ones

According to our tests, some cheap Asda microwaves are almost twice as good as branded ones – although not all Asda models get top scores.

Buying a cheap microwave: what are the compromises?

Most cheap models are solo microwaves, which means they don’t have a convection oven or grill function – if you want a microwave that does more, you usually have to spend more.

Even within the field of solo microwaves, there can be some big differences between low-cost and pricier models. More expensive models often have digital controls, which means the timer is more accurate, and a better range of automatic programmes.

Some models also have multi-stage functions, which means you can queue up settings in advance (for example, if you want to defrost then heat a dish), and pre-set options which store your preferred settings.

The table below shows how two similar-looking black and gold microwaves compare – although the Swan SM22045BLKN Gatsby is twice as expensive as the Asda GMM101GMB-20, it comes with more features. 

You should decide whether you’ll get enough use out of them to justify the extra cost.
