NEFF KM3963XE0 Fridge-Freezer: Class E, Not C as Release Says

NEFF’s press release of 19 September 2026 presents the Multi Door fridge-freezer KM3963XE0, and it lists “Energy efficiency class: C”. NEFF’s own UK product page and its EU product information sheet both say class E, at 327 kWh per year. The regulatory sheet says E, and that is the figure to trust.

This is also not a same-day launch. The release itself states the model “is available from May 2026”, so it has been on sale for about four months. NEFF names no recommended price in the release.

What does NEFF say the KM3963XE0 offers?

According to NEFF, the appliance has XXL capacity and an Integrated Ice & Water Dispenser that delivers filtered chilled water, crushed ice and ice cubes, for up to 160 ice-cold drinks per day. NEFF says it connects directly to the water tap and makes up to 5 kg of ice per day continuously.

Other NEFF claims: a FreshSafe 0 degrees Celsius drawer for fish and meat, a FreshSafe drawer with humidity control for fruit and vegetables, a Bottle Flex Rack, Total No Frost, a metal back panel and LED lighting. The black-inox surface is described as anti-fingerprint. It can stand freestanding or sit in a niche as a slot-in product.

The release profile gives a width of 90.5 cm, a height of 183 cm, a net fridge volume of 375 l and a net freezer volume of 199 l.

Which numbers does the EU sheet give?

The EU product information sheet (Regulation (EU) 2019/2016, PDF footer dated 27.08.2026) states:

• Energy efficiency class E, EEI 97, 327 kWh per year.
• Total volume 574 l: 375 l fresh food and 192 l four-star freezer at minus 18 degrees Celsius, plus a 7 l 0-star, ice-making compartment. That split is how the release’s 199 l freezer figure adds up.
• Freezing capacity 16.0 kg in 24 hours, with a fast-freeze facility.
• Sound level 39 dB(A), noise class C. The sheet also gives a minimum guarantee of 24 months and LED as the main light source.

NEFF’s UK page adds dimensions of 1830 x 905 x 731 mm (H x W x D), a net weight of 137.9 kg, control by button and by app, and a climate class from extended temperate to tropical.

What do we not know?

NEFF’s documents disagree on the energy class, and we do not know why. The release says C, the UK page and the EU sheet say E. Note that the noise class printed on the same sheet is also C, which is a different measure from energy efficiency. No NEFF source we found gives a price.

What should a shopper do?

Read the EU sheet or the energy label, not the press release. Class E at 327 kWh per year is the figure that matters for a 574 l appliance, so compare it with what your current fridge uses. The label scale runs from A to G, and our guide to the EU energy label explains how to read it.

Plan the space. At 90.5 cm wide and 73.1 cm deep, measure the gap and the door swing first. The dispenser needs a direct water connection, according to NEFF’s UK page, so budget for plumbing. The 24 months on the EU sheet is the stated minimum guarantee. Browse refrigerators to compare it against other large models.
