Of all your household appliances your fridge/freezer often consumes the most amount of energy in your home.

Your fridge/freezer gobbles up a huge amount of energy and is often home to lots of forgotten leftovers that go off sitting in the fridge for too long.

With that in mind we have compiled 6 ideas that should save you money:

1) Move your fridge away from the wall

Often we make the mistake of pushing our fridge too close to the back wall. By pulling the fridge forward a few centimetres it can help reduce the energy used by the fridge by as much as 40%. Now that’s a big saving.

2) Buy a thermometer and pop it in the fridge

The ideal temperature for your fridge should be 3-5 degrees celsius and the freezer range is -18 to -15 degrees celsius. If the temp is too low it can affect the quality of your food as well as burn extra energy. If the temp is above this range it can also affect the quality of your food.

3) Clean the coils

Dust builds up on the coils at the back of your fridge and so the condenser kicks in more often and has to work harder, using more energy and costing you more money. Pull out the fridge and use your vacuum to clean off the excess dust both on and around the fridge. Make sure you do this regularly!

4) Fill your empty containers with water and put in the freezer

Your freezer works best when it’s  full. Cold items help keep other items cold and maintains a low temperature. Rather than filling your freezer with unnecessary food that you may forget about, get an empty milk container and fill 75% with water and put it in the freezer.

5) Get rid of your leftovers

Do your leftovers get pushed to the back of the fridge and get forgotten until you see mould growing on them?

Here’s a simple way to work out what to get rid of each week.  Have on hand some coloured washable markers and allocate a colour for each day. When adding something to the fridge write on the container with the coloured marker for that day, that way you can categorise food by how long it’s been in the fridge. Sunday night glance in the fridge and look for Monday’s colour and throw it out.

6) Add a ‘leftover veggies’ container to the freezer

Do you often have a few veggies left over at the end of the meal? Rather than throwing them in the bin put them in a small container in your freezer. Once the container is full, boil some water, add some spices, meat of your choice and stock and boil away. You then have a yummy, inexpensive soup – especially great in winter!

  • Thanks for the tips, great.


  • The tip of add a leftover vegetables container to the freezer, that’s what I have been doing wrong, I haven’t been doing that. Thank you.


  • Closing the door slower not so sharply to let less cold air out basically dont open the fridge just to look in it and drink normal tap water not refrigerated to save on opening the fridge frequently


  • All great ideas! Checking the seal on your fridge freezer every so often is a good idea too. You can do this by placing a piece of paper between the seal when you close the door; if you can pull the paper out without any resistance it’s definitely time to replace your seal!


  • Great ideas here, and all so simple really,! I wonder why I hadn’t thought of some myself! I really like the one about making soup from left over veggies! Great idea


  • Never thought of keeping left over veges for soup. I normally give them to my dog!


  • Excellent some great ideas right here.


  • Point #1 – I had no idea! Thanks for sharing these tips.


  • I LOVE the leftover veggie tip! I always make too many, this would be a good way to save waste


  • We practice these tips except for placing an empty water container in the freezer, as I always have a lack of space. I do not only freeze vegetable leftovers, I also freeze vegetable scraps and peels. It makes the most beautiful stock,


  • Another tip: never install the fridge close to the oven. Too many people still do it.


  • Knew about half of these tips but I love number 6. Not something I would have thought of so thank you for the suggestion


  • Love tip number 6, but never seem to get any leftovers in my house. Thanks for the post.


  • Great tips – I’d also like to add:
    Don’t overfill or cramp your fridge: It’s a known fact that fridges are most energy efficient when they are full, but it is important to ensure that there are slight gaps between items to allow proper air flow and circulation;
    Don’t place hot items in the fridge: It’s important to wait until a dish has cooled down before placing it in the fridge. Put cold items back into the fridge after use, rather than letting them warm to room temperature
    Don’t open the fridge door too often: your household fridge uses more power than any other appliance. Try to limit the number of times you open the fridge door and never leave it open.


  • My fridge/freezer is 27 years old so I can’t imagine it’s working at its best. These are all great tips and ones I will try to follow. You are often limited in a kitchen space in where you can place your fridge so moving away from the wall is tricky. We do have airflow either side, but I’d hate to look at the coils at the back of the fridge. Don’t make me do that!!!
