With an A++ rating for energy efficiency this Siemens model is by far the most efficient on my list. It'll cost just over £25 a month to run, which is much cheaper than an older, less efficient model. You can spend more money filling it up! You're getting a huge capacity of 195 litres, so it's great if you have a lot of mouths to feed.
Like my winner, this model's frost free. This means ice will never have the chance to build up inside, so you'll never have to waste time defrosting. Another handy feature is Vita Control. Basically, it senses the temperature inside and makes sure it's consistent across all of the compartments. There are 5 drawers and 1 pull down flap, as well as an ice tray and integrated ice pack in the door.
Another great function is Super Freeze. It quickly lowers the temperature to make sure any new food added is frozen in no time, locking in all the flavours and nutrients.
