How we test single use

We test how quickly and evenly microwaves heat in microwave mode and we record how much water is lost from the food during cooking. This is the overall score for microwaves heating one dish, from cold, in microwave mode.

How we test speed of heating

We test how quickly the microwaves can heat up when cooking in microwave mode.

How we test evenness of heating

We check for hot and cold spots in food to make sure it's evenly cooked.

How we test quality of food

We test how much water is lost from food when heating in microwave mode.

How we test continuous use

This is the overall score for microwave heating when the microwave has previously been in use and has warmed up. We test how quickly and evenly microwaves heat in microwave mode and we record how much water is lost from the food during cooking.

How we test manual defrost

How evenly the microwaves defrost minced meat on a manual setting.

How we test auto defrost

How well the microwave defrosts using its automatic defrost program.

How we test steaming

How well the microwave steams a meal of fish, potatoes and veg.

How we test ease of use

This includes setting the clock, opening and closing the door, loading and unloading the oven, using the power and time controls, reading the display, cleaning, and the instructions and information provided by the manufacturer.

How we test cleaning

How easy it is to clean inside the microwave and the exterior casing.

How we test quietness

We test how noisy each microwave is in microwave heating and defrosting mode.

How we test energy consumption single use

How much energy is used by the microwave to heat food when it is only used once.

How we test energy consumption repeated use

How much energy is used by the microwave to heat food when it is being used in quick succession.
