Bosch freezers come in freestanding and built-in versions, from compact undercounter models of around 83 to 97 litres to a tall upright holding 334 litres. Most are Series 4, alongside a Series 2 undercounter and a Series 6 integrated freezer, so the range suits a small flat as well as a household that batch-cooks.

The first choice is how the freezer deals with ice. Frost Free models defrost automatically, using sensors to remove moisture before ice forms, so you never need to empty the freezer to defrost it. Low Frost models reduce ice build-up but still need an occasional manual defrost; this applies to the Series 6 integrated freezer and the Series 2 model in Bosch freestanding non frost free freezers. Some models also connect to the Home Connect app.

For a fitted kitchen, Bosch built-in freezers include a tall fully integrated Frost Free freezer of 212 litres plus smaller built-under and integrated options, all with fixed hinges that attach the furniture door directly to the appliance door. The white Bosch freestanding freezers include 60 cm models of 200, 225 or 242 litres; the 334-litre model is rated D for energy, the others E.

Start with where it will go: under the worktop, behind a cabinet door or standing alone. Then decide whether automatic defrosting matters and match the capacity to how much you freeze.
