NEFF vs Siemens Freezers

NEFF and Siemens share a lot of engineering, so their freezers are close rivals. NEFF's tall GI7815CE0G N90 model costs £1,149 and its GI7812EE0G N50 tall model £1,229, while Siemens' GS36NVIEVPG iQ300 242-litre upright is £849 and its iQ500 GS36NAXEP 242-litre tall freezer is £949. The NEFF GI7815CE0G is £300 more than the Siemens iQ300, and the NEFF GI1216DE0 undercounter at £629 is £20 cheaper than the Siemens GU21NVFE0G at £649.

Both brands use noFrost or Full NoFrost technology, so you never defrost. Siemens adds freshSense sensors that monitor and control temperature fluctuations, and Home Connect for remote control by smartphone, with its freezers ranging from 150 to 400 litres. NEFF's built-in N50 and N90 tiers use Full NoFrost, and its freezers are built to fit behind cabinet doors. The main technical differences are Siemens' freshSense and Home Connect against NEFF's integrated fitting and tier structure.

NEFF suits fitted kitchens that want a freezer to pair with a NEFF built-in larder fridge, with a consistent look across the kitchen. Siemens suits buyers who want smart features and a tall freezer, with the iQ300 offering a cheaper route to 242 litres. Siemens guarantees spare parts for 10 years after a model is discontinued, which matters for a freezer that typically lasts 10 to 15 years. Check upright width, typically 60cm to 70cm, before buying. The NEFF N90 tiers offer more features than the N50, so compare the tier before deciding. Both brands share BSH engineering with Bosch, so their designs have common ground.

Bottom line: choose NEFF if you already use a NEFF built-in fridge and want a fully integrated, no-defrost freezer from £599. Choose Siemens if you want smart Home Connect control and 242 litres for £849 to £949.
