Traditionally fridges, freezers and fridge-freezers have been among the highest energy users in the home and the first that you should consider replacing as they are usually on for 24 hours a day and 365 days a year.
A case study revealed that a 30-year old fridge freezer used almost 140 watts of power. This is equivalent to about a dozen 11 watt low energy light bulbs switched on all day and all night every day of the year. Not only did this hidden guzzler lead to over half a ton of unnecessary carbon dioxide emissions a year — it also cost its owners an extra £137 a year on their electricity bill.
A high quality modern fridge-freezer should use less than 50 watts of power. If your unit is using more that this when you measure its consumption you should consider replacing it. If you don’t want to go to the trouble of measuring this our savings calculator will do the job for you.
The energy consumption of fridge freezers has dropped dramatically in recent years. Look out for A++ models, these may use up to 60% less electricity than even ‘A’ grade models.1
