All experts agree that consumers should check the energy rating of a fridge-freezer they're interested in.

Designed with food preservation in mind, the Bosch Serie 6 KGE49AICAG features a “super freeze” function that freezes food quickly, keeping your food at the optimum temperature. If the back of the fridge compartment becomes compacted with ice, this can block the drain channel, trapping debris which can start to become mouldy. Many fridge-freezer brands shout about their various features, so navigating what’s important and what’s not can be a bit of minefield.In the fridge compartment, there are four racks, plus a handy salad crisper to keep fruits and veg fresher for longer. This nifty feature helps stop those energy-guzzling moments when you’re standing with the fridge door open, hoping inspiration strikes. Keep it full (but not too full): a semi-full fridge-freezer doesn’t have to work as hard to keep the cool air cool compared to a near-empty fridge-freezer. On a practical level, compacted ice not only takes up valuable freezer space but it also stops your freezer from working efficiently.

Sophie Beckett-Smith says, "Choosing a fridge-freezer with a good energy rating will save you both money and energy. His architectural skills are not limited to designing the plan for structures alone, but it extends to aesthetics and home décor. At the premium end, this could also look like ‘transparent’ doors so you can easily peek in the fridge or screens”. As great looking as some of the larger models on this list are, they’re not always a practical investment. Integrated: integrated fridge-freezers are designed to be fitted with the same panelling or design as the rest of your kitchen.

It’s not always about having the biggest, most popular product, but rather what caters to your needs. If you like to have filtered water and ice on tap, but can’t afford a model with a water dispenser, choose a water filter jug instead. The seals of the door also have a special antibacterial coating on them to keep food fresh and nasty smells at bay. There’s NatureFresh that ensures the inside is an even and consistent temperature, and Pure N Fresh, which is a filter that removes odours and keeps your food fresh and Super Cool, which will rapidly cool the fridge compartment after lots of food has been placed inside. This model also comes with a handy door alarm and the door is reversible, so you can get the design of your kitchen exactly right.
