Energy Efficiency Alert – Martin Lewis Urges Correct Fridge and Freezer Settings

Martin Lewis Warns Against Costly Mistakes in Fridge and Freezer Usage

Renowned financial expert Martin Lewis, host of ITV’s The Martin Lewis Money Show and founder of Money Saving Expert, has issued a crucial warning about common mistakes that may result in unnecessary expenses related to fridges and freezers.

Optimal Temperature Settings:

Lewis emphasizes the significance of setting the correct temperatures for fridges and freezers to avoid excessive energy consumption.

He advises that the ideal temperature for a fridge is five degrees Celsius and minus 18 degrees Celsius for a freezer.

Going colder than these recommended temperatures could lead to increased energy costs.

Proper Food Defrosting and Fridge Usage:

The financial expert recommends defrosting food in the fridge, as it acts as an effective ice pack, aiding in maintaining cooler temperatures.

Lewis also suggests keeping the fridge three-quarters full and using bottles of water to fill empty spaces without overloading, as overloading can strain the appliance’s efficiency.

Regular Maintenance and Airflow:

Lewis stresses the importance of regular defrosting for both the fridge and freezer to ensure optimal performance.

Additionally, the Energy Saving Trust advises keeping a minimum 10cm gap behind the fridge to facilitate better airflow and heat dissipation.

The Trust further emphasizes the impact of choosing energy-efficient models based on the A to G energy label scales.


Martin Lewis’s warning extends beyond mere financial advice, delving into practical tips for efficient fridge and freezer usage.

The emphasis on optimal temperature settings, defrosting techniques, and regular maintenance aligns with broader energy-saving recommendations.

By being mindful of these aspects, individuals can potentially save on energy costs and contribute to environmental sustainability.
