Siemens built in freezers are fully integrated, so they sit behind a furniture door and blend in with the rest of your kitchen units. Every model here is frost free: Siemens' noFrost system moves excess moisture out of the freezer and uses sensors to manage the temperature, so ice doesn't build up and you won't need to defrost by hand. You'll find all of them among our Siemens built in frost free freezers. Each has an E energy rating, a 35 dB noise level and a fixed hinge, where the furniture door is attached directly to the appliance door and the two open together.

The main choice is size. Siemens tall built in freezers give 212 litres of net storage, enough for a household that freezes in bulk or wants a freezer to pair with an integrated fridge. The iQ700 model has electronic controls with an LED display and a reversible left-hand hinged door, while the iQ300 version has touch controls and a left-hand hinge. For a smaller kitchen, Siemens undercounter built in freezers fit beneath the worktop with 85 litres, a right-hand hinged door and Home Connect, so you can check and adjust the freezer from the app on your phone.

To narrow it down, measure whether you have a tall housing or a gap under the worktop, then check which way the door needs to open, since only one tall model is listed as reversible. For a broader view, browse all Siemens freezers.
