Fancy putting a freeze on your electricity bill?

Then knowing how you can save energy and the environment using just your fridge freezer may come in handy for you.

The point is, saving energy and saving the planet doesn’t have to be hard as people make it out to be. And doing so not only benefits our wallets but also helps our country’s national energy grid, especially during a global pandemic.

The energy grid is always working around the clock to ensure a steady flow of electricity to our homes. Over the past few months, Covid-19 has certainly had an impact on domestic electricity demand, which is only going to get higher as many of us stay at home longer.

Ultimately, we want to avoid unnecessary in spikes in energy usage. This is why it’s so important for us to do our part to help the grid operate effectively by using our household appliances as efficiently as possible in the coming months.

So, to help bring us closer to a healthier and greener planet, in the first part of The Energy Saving series we look at one of the most trusty but expensive appliances – the fridge freezer.

How Your Fridge Freezer Can Save You Money and Energy

It comes as no surprise to learn that fridge freezers are the most power-hungry household appliance and use the most energy of all. After all, our fridge freezers are constantly on 24 hours a day, 7 days a week.

In fact, refrigerator appliances have doubled in energy consumption over the past 40 years. However, advancing technology is helping to make them more energy efficient.

Given refrigerator appliances tend to use around 20% of all household electricity usage, it’s certainly worth knowing how you can get the best out of your appliance, as well as protecting our planet.

With that in mind, let’s get into some energy-saving tips for your fridge freezer:

Fridge Freezer Temperature


To ensure you’re saving energy, your fridge freezer should ideally be kept at a temperature of about 3-5 degrees whilst your freezer should be set around -18 degrees.

These temperatures allow the fridge and/or freezer to slow down the growth of bacteria, making sure your favourite food is kept fresh without using unnecessary amounts of additional energy. Just try not to open the door too often as it will release the cool air and force the appliance to work harder.

By keeping the temperature at optimum, not only are you saving energy and the planet, but you are also cooling down those future energy bills!

TIP: Remember, if you have made changes to temperature settings, it often takes about 24 hours for your appliance to adjust, especially fridges.

Storing Hot Food

Storing hot food in your fridge freezer is a frequent debate among kitchen and food enthusiasts – too many cooks spoiling the broth it would seem.

One thing is for certain though - if you want to save some energy then it’s best to avoid placing hot or warm food in your fridge freezer as you will use up more energy just to keep things cool.

TIP: Best practice here is to allow the hot food to cool down to room temperature before placing it into your refrigerator.

Smart Positioning

The number one rule when finding a place to position your fridge freezer is always to avoid anything that’s going to get hot – cookers, tumble dryers, dishwashers and radiators are obvious examples.

In recent years, people seem to be moving away from the conventional kitchen set-up. Instead, people have been leaning towards placing their refrigerator appliance in areas such as outbuildings, utility rooms or garages.

There are many reasons for this (i.e space saving) but the logic of doing this makes sense, especially from an energy saving perspective.

Either way, wherever you position your fridge freezer depends on:

  • The area being dry and cool
  • Electricity access
  • Ensuring the appliance can operate in cold environments.

Some Final Tips Before You Go

The following tips are just further examples of how you can do your part in protecting planet and save energy at the same time:

Size matters – The bigger the appliance, the bigger the energy costs.

Ensure door seals are clean – Regular maintenance will prevent faults with your fridge freezer. Be sure that any faulty doors and seals are not leaking that all important energy!

Check the label - Now that all fridge freezers contain European Energy labels, it’s good practice to check these labels to see the what the fridge freezer energy rating is to see how much energy is used. If you’re in the market for an upgrade, then this is particularly useful - you will want to choose an energy saving fridge freezer that will cut costs and do its part for the environment.

Final Thoughts

The disruption of Covid-19 has only further illuminated the importance of saving on household energy.

Although these are unprecedented times, the ambition to save energy and the planet doesn’t have to be complicated or daunting. Helping our planet starts with you - changing some of our daily habits, such as in the kitchen with your fridge freezer, can make a big difference.

A rewarding feeling of protecting the planet and saving some money at the same time definitely sounds like a pretty good deal.
