Cooking adds up to about 4% of an average energy bill, but by being careful with the way you cook your food, can reduce energy consumption. 

Microwaves are usually the most energy efficient way to prepare a meal - they heat up quicker, reducing the cooking time. Other than a microwave, you could use an electric oven or a hob to cook your food. All electric ovens come with an energy rating - an A+ rated oven can consume 40% less energy than a B rated oven. 

Cooking your food on a hob is more efficient than using an oven, with several types of oven hobs to choose from:

  • Induction hobs 
  • Ceramic hobs 
  • Halogen hobs 
  • Electric plate hobs 

Smart tips for your cooking appliances 

  • Cut food into smaller pieces before cooking as it may cook quicker
  • Make sure you are using the right size cooking ring for the pan you are using
  • Keep the heat in the pan by keeping the lid on as much as possible 
  • Cook large batches of food together 
  • Don’t keep opening the oven door when you are cooking 

Fridges and freezers 

Fridges and freezers are switched on 24 hours a day, seven days a week - so its no surprise that they account for around 20% of electricity used in the average UK home. 

Choosing an energy efficient fridge or freezer can help to cut your bills - upright freezers are less efficient than chest freezers as cool air drops out of an upright freezer when you open the door. All fridges and freezers come with an energy efficiency rating, based on their size - a smaller A rated fridge could use less energy than a larger A+ rated appliance. 

Smart tips for your fridge and freezer

  • Don’t put your fridge or freezer next to a cooker or in the sun - it will work more efficiently if it’s kept cool
  • Make sure air can circulate around the back of your fridge or freezer, and it keep it dust free 
  • Don’t leave the door open for longer than needed - load and unload your fridge or freezer and quickly as possible 
  • Never put hot food in the fridge, let it cool down first as it will use more energy if the food is hot/warm
  • You should keep your fridge between 3 and 5 degrees and your freezer to be kept at -18 degrees 
  • Defrost your fridge or freezer regularly 
  • Check for any gaps in the seals that might let warm air in  

By implementing small energy efficient measures in your kitchen, it can lead to savings on both your energy consumption and overall bills.
