AEG freezers come in built-in and freestanding versions, from compact under-counter models to full-height uprights. Most belong to AEG's 7000 Series, with 3000 and 6000 Series models for smaller spaces. That makes the range useful whether you're planning a fitted kitchen or adding freezer space in a utility room.

The main choice is between frost free and Low Frost. The 7000 Series frost free models stop ice building up, so you never have to defrost by hand. Low Frost uses hidden cooling circuits to slow frost build-up, which means defrosting is easier and needed less often. You'll mostly find it on the smaller under-counter models. The integrated LowFrost model has OptiSpace, with removable boxes so you can arrange the storage your way, and Frostmatic for quickly freezing fresh food. The 3000 Series built-under model has Extra Freeze for the same purpose, plus a door alarm.

Among the AEG built-in freezers, the fully integrated 7000 Series frost free models hold 212 litres and are rated at 35 dB. They're right-hand hinged, with either sliding fittings, which carry a matching cupboard door on rails, or a fixed hinge. The AEG freestanding freezers range from a compact 85-litre white model to a 278-litre frost free 7000 Series model in matt black with a digital display.

Start with where the freezer will go: behind a cupboard door or standing on its own, and full height or under the worktop. Then decide whether frost free convenience is worth more to you than a smaller Low Frost model. If you also need fridge space, compare the AEG fridge freezers.
