Keep your fridge full
Apart from keeping the fridge closed which is known by all, one other thing to help you save money is to keep your fridge and freezer full. It is advisable to keep the freezer or fridge packed as this will reduce the amount of time that the fridge has to run to stay cool. Cover your foods and drinks before putting them in the fridge as well. If you are using an old fridge, consider replacing it with a new one as old fridges consume a lot of electricity.
