Best energy-efficient fridge freezers for sustainable living 2025
Best for: 'A' class pure class for the deep of pocket
Miele, maker of white goods wonderment. Ludicrously expensive. Built to last. Imbued with all the innovation. And that's me generalising about all their appliances, before I focus fully on its KFN 4795 AD, which – spoiler alert! – is ludicrously expensive, built to last, and imbued with all the innovation.
From the outside, it's a big box with a stunning 'BlackSteel' finish and nicely bold, chunky handles for both fridge and freezer sections. A 70/30 design, the Miele features a full 'A' class rating for energy efficiency and offers you, the lucky/rich owner, a capacious 371 litres of space inside, split 268 to 103 litres respectively in the fridge and freezer. And exerting effortlessly precise control over the airflow in those two spaces is 'DuplexCool', keeping cooling separate, 'DynaCool' to ensure temperature distribution is uniform, and a no frost system to keep you from having to get your hands cold as you chip away at ice build-up.
Storage-wise, there are tons of places to put your stuff in the fridge, thanks to a full 5x shelves, 4x door shelves, a crisper drawer and bottle rack, while the freezer features a further three drawers for all your frozen fare.
With an annual energy consumption of 103.66kWh, at prices as of April, that works out at a cost of £28.02 per year, which shouldn't break the bank, so you may have spent the lion's share of 2.4K on a fridge-freezer, but tested to last 15-years but at least you know that powering the thing for the next decade and a half won't cost anywhere near as much as running a far cheaper, less efficient option.
As with all the best appliances, the Miele also comes Wi-Fi-enabled, letting it link up with your home network for monitoring over the Miele@home app, so that'll keep the tech-heads happy too. And last but not least, running at a whisper-like 34dB the KFN 4795 AD is also the proud owner of a Quiet Mark award, so the complete package of peace of mind when it comes to both pocket and planet, and peace of ear too – for those with the requisite amount of pennies, it's worth every one of them.
