Electrical Saving Tips

You can minimise electrical costs on your greedy appliances by following these simple guidelines:

⚡Heating and Lighting

As well as turning the thermostat down you can also let as much sunlight into your home during daylight hours and close all curtains and blinds at night to keep the heat in.

Switch to energy-efficient bulbs with LEDs being the most efficient as they can last up to 20 times as long as a conventional bulb.

⚡The Dishwasher

For lighter loads of dishes try handwashing instead of using the machine – maximise cleansing options by only using the dishwasher with a full load.

⚡The Fridge

Choose a new appliance with an A+++ rating as this can consume up to 80% less energy and release minimal Co2 emissions.

Don’t leave the door open as this makes the fridge work harder and use more energy. Defrost as recommended – many modern fridge freezers have an automatic setting.

Set the fridge temperature between 2 and 3.5 degrees. And the freezer between -18 and -15 degrees. Pack the freezer properly. And check seals for wear and tear ongoing.

⚡The Oven

Make better use of the toaster and the microwave to help save on electricity.

⚡The Tumble Dryer

Don’t overfill the dryer as this prevents the drying of clothes properly. And when the weather is suitable, hang the clothes outside to dry.
