Services Connection, Disposal, Disconnection


  • Connection £ 24.99

    We’ll get your new fridge freezer in place, level the feet and take away all the bulky packaging for you. Your new appliance will need to sit for a few hours before it’s plugged in. This is important as it ensures the gas coolant inside the fridge settles

  • Disposal £ 29.99

    We’ll happily take away your old appliance for you and recycle it. All we ask is that it's disconnected, emptied, fully defrosted and free of any ice and water. The fee for this service relates to the cost of taking your old appliance away on our van rather than the recycling service.

  • Disconnection £ 4.99

    We’ll disconnect your old appliance when we deliver your new one

    • This includes disconnecting it from your water pipes if it’s plumbed in

Product Overview

The perfect environment for keeping your food fresh. The Neff K3990X7GB American Fridge Freezer eliminates the transfer of odours and ensures your food remains fresher for longer because of the Supercool and Superfreeze functions. Both rapidly lower the temperature, so you can restock the weekly shop and your groceries will quickly return to the recommended temperature. You don’t need to worry about the build up of ice either as there’s a handy auto defrost setting.

Features we love

Good capacity

Packed with 343 litres of capacity across the fridge and 175 litres across the freezer, you have ample storage space for a large family. The total capacity is a huge 518 litres which is equivalent to nearly 3 shopping trolleys worth of groceries, so you can buy more and shop less.

Frost free

The Superfreeze setting will rapidly cool your tub of ice cream for the kids’ weekend treat, and the Supercool setting will cool your fridge for the weekly shop. You’ll be saved the job of defrosting too because the frost free feature prevents any unwanted ice building up. This clever tech helps the appliance maintain its impressive A+ rating for energy efficiency.

Advanced freshness tech

Your food will stay fresher for longer and remain at the correct temperature thanks to the Multi AirFlow cooling feature, which keeps the air in the fridge at a consistent temperature. The clever VarioBox lets you tailor its temperature to one of three settings, so you can keep your veg or meat in perfect condition.

Enjoy fresh water and ice

The plumbed in filtered water and ice dispenser gives you chilled, fresh water at the push of a button, encouraging you and your family to drink more healthily. This is a plumbed in model so you’ll have a constant supply of chilled water.

Excellent look and feel

Very heavy and well built, clean simple lines. Interior fittings feel robust and I am happy with it so far. I have only had it a week but its a lot better than the LG model I previously had. I am glad I invested in a higher end American Fridge Freezer. I spent a fair amount of time shopping around & I am not disappointed with this Neff model. Its very quiet too You get what you pay for! Quick and simple delivery and ordering. Impressed with AO so far.

Neff American Fridge Freezer

The product is expensive but you only get what you pay for. We are both very happy with our product as Neff is an excellent range. It's a really nice feature in the kitchen, stainless steel and not plastic, built very well, easy to use and it keeps the food so fresh its amazing!! It does need to be plumbed in whenever you are ready as you can use the fridge freezer before hand. We love it - so glad we purchased it !!!
