Neff fridge freezers here are all built in and fully integrated. Each one sits behind a kitchen furniture door, so it blends into your run of units. The range covers Neff's N30, N50 and N70 series. Fridge sections run from about 150 to 285 litres and freezers from 70 to 99 litres, which suits anyone from a couple in a compact kitchen to a family that shops in bulk. Every model is also listed under Neff built-in fridge freezers.

The split between fridge and freezer is the first thing to decide. Most models put the fridge on top in a 70/30 or 60/40 split, giving more room to fresh food. Some N30 models have an even 50/50 split with the freezer above the fridge, which helps if you rely on frozen food. Most of the range is frost free: dry air circulates through the freezer so ice doesn't build up, and you never have to defrost by hand. The Low Frost models cut frost build-up rather than prevent it. You'll still need to defrost now and then, just less often. Look out for the BigBox, an extra-large freezer drawer for bulky items, on selected Low Frost models.

Check how your current appliance is fitted before you choose, because Neff offers both sliding hinge and fixed hinge versions. With a sliding hinge, runners link the furniture door to the appliance door. It's quick to fit and common when replacing an older appliance. A fixed hinge fixes the furniture door directly to the appliance door so the two open as one, which feels sturdier. Energy ratings are D or E, and noise levels range from 34 to 39 dB. Some N50 and N70 models connect to the internet, and selected models add an open door alarm or a super setting for the freezer.

To narrow it down, start with your housing and hinge type. Then pick a split: 70/30 if you mostly buy fresh food, 50/50 if you want more freezer space. Go frost free if you'd rather never defrost.
