Mini fridges are handy for all sorts of spaces, from studio flats and home offices to student rooms and garden sheds. If you’re after one that won’t run up your electricity bill, it’s worth knowing which models are built with energy-saving in mind. Some are surprisingly efficient, using far less power than you’d expect for their size. Below, we’ve picked out a few of the most energy-conscious mini fridges on the market, with attention to how well they’re made, how quietly they run, and how much electricity they use day-to-day.

Do Mini Fridges Use a Lot of Electricity?
No, mini fridges are generally energy efficient. Most models use between 100 to 300 kilowatt-hours (kWh) per year, which translates to around £30 to £90 annually. Newer models with good energy ratings tend to be on the lower end of that range.
Can You Leave a Mini Fridge on All the Time?
Yes, and most people do. Mini fridges are made to run 24/7. The key is to make sure they’re in good nick and not blocked or overheating. If yours is making strange noises or seems hot to the touch, it’s worth checking it over. Otherwise, just plug it in and let it do its thing.
How to Make Your Mini Fridge Even More Efficient
Buying an energy-efficient mini fridge is a solid start, but there are a few things you can do to keep it running at its best.
Give it breathing room
Mini fridges need decent airflow around them to avoid overheating. Don’t shove it in a tight corner or cram it up against the wall. A couple of inches of space around the sides and back makes a big difference.
Keep it away from heat
Avoid placing your mini fridge right next to a radiator, cooker, or direct sunlight. The more heat it has to fight off, the harder it works and the more energy it uses.
Don’t overpack it
A tightly packed fridge can mess with airflow and make it harder for cool air to circulate. Leave some space between items, and don’t block the vents.
Keep the coils clean
Every few months, unplug it and give the back a quick dust. Dirty coils can slow things down and use more power.
Check the seal
If the door seal isn’t tight, cool air can leak out without you noticing. Run your fingers around the edge to make sure it’s snug. If it’s cracked or loose, it might be time for a new seal.
