Money Saving Expert Martin Lewis Issued a warning about common blunders that could cause people to waste money with their fridges and freezers. The finance expert and presenter shared just how much not having your fridges and freezers on the correct temperature could be costing you.

He shared some top tips which could avoid people spending unnecessary money. He emphasised: "Five degrees is the right temperature for a fridge, no colder. Minus 18 is the right temperature for a freezer."

The man from BBC Sounds said setting temperatures too cold leads to needless use of energy. He suggested defrosting food in the fridge as it works like an ice pack, helping to keep things cool, and endorsed keeping the fridge three-quarters full.

He added you should fill empty space with bottles of water but not overload the appliance as it can wear it out. Regular defrosting of both the fridge and freezer was advised for top performance.

Meanwhile, the Energy Saving Trust highlighted the need for a minimum 10cm gap behind the fridge for better airflow and heat scatter. They mentioned: "These are switched on 24 hours a day, seven days a week. They're some of the longest lasting appliances in our homes, so it's worth finding energy efficient models."

It said: "Energy label scales range from A to G, and choosing a higher rated fridge freezer can have a significant impact on your running costs. Choosing a A-rated fridge freezer over a F-rated unit will save you about £610 (610kgCO₂e) in energy bills over the 17-year lifetime of the product."

"However, as the energy rating is categorised by size, choosing a smaller fridge will use less energy than a larger fridge with the same energy rating, and may even use less than a higher rated one. You can compare the total energy consumption of appliances by looking for their yearly energy consumption in kWh/annum (this is displayed under the rating scale on the energy label)."
