What to look for when buying a standalone freezer.

20feb freezers hero

Our test assesses how well freezers manage temperature on a daily basis as well as how fast they are to warm up when power is cut and how quickly they cool back down.

We've tested 12 freezers.

Overall score breakdown

Overall score is based on

Temperature performance (55%)

Warm-up (30%)

Cool-down (15%)

Temperature performance

Our temperature performance assessment includes: How well a freezer maintains even temperatures, how it copes with changes in ambient temperature, whether it allows a good range of temperature choices and if its default setting results in an appropriate temperature.

Warm-up

This is how long it takes the freezer to warm up if power is cut. The freezer is switched off in a room with an ambient temperature of 32°C. We time how long it takes for the freezer to warm from -15°C to -5°C.

Cool down

We measure how long it takes to cool the air in an empty freezer from when it’s switched on until it reaches -13°C in a warm (42°C) temperature-controlled room. Cool-down times will be longer and more variable with food in the freezer.

Energy usage

We compare energy use to the manufacturer’s claim. A pass means energy measured was no more than 7.5% higher than claimed, anything over that is a fail. If a freezer fails our test, it’s not necessarily bad, just not as efficient as the manufacturer says it is.

Noise

Freezers can be a noisy appliance, so we test noise to help you find the quietest model. Our noise test is conducted while the freezer’s compressor is turning on and off, but not while it’s defrosting. Measurements are taken a metre away and up from the floor. While our noise measurements are objective (31dBA is 31dBA), how people perceive noise is subjective. This is why we don’t consider noise when scoring freezers.

Reliability and owner satisfaction

Each year, we ask our members if products are reliable and satisfying to own.

We only analyse results for brands with more than 30 responses in our survey. Reliability is the percent of products from a brand that have not had a fault, while satisfaction is the percent of owners who say they are “very satisfied” (scoring the product 8, 9 or 10 on a 0-10 scale).

We don’t include reliability or satisfaction in our overall score, but we won’t recommend a product that has below average reliability.
