• Speed matters. Ask yourself is there a more efficient way to cook something? If you're using an oven to cook, are you able to use an air fryer, slow cooker or microwave instead? Simmering rather than boiling could reduce your energy costs. Try using a slow cooker, cooking at lower temperatures for longer will be more cost-effective than using an oven.
  • Utilise space. Don’t use a large appliance such as an oven to cook something that could fit in an air fryer or microwave. Try doubling up and steam vegetables on top while you are boiling potatoes in the same pot.
  • Batch cooking Another way to be more efficient with energy is to batch cook. Cooking enough to do a few meals, freezing portions for a later date, or cooking several foods (for example a casserole and some baked spuds) at the same time whilst the oven is on can save approximately £158 over a year!
  • Keep it in and keep it closed. Where possible, put a lid on your pots and pans to save on boiling time. Using the right-sized pan with a lid will save around £72 on your annual energy costs. Try to reduce the number of times you open the oven door or lift the lid of the slow cooker so that you don’t lose the temperature.
  • Don’t leave it on standby. Your electric oven, microwave, dishwasher and washing machine eat up electricity when left on standby. Turning your appliances off standby can save you an additional £45 on your energy cost a year.
