Summer energy saving tips
Give hard-working appliances a summer service
In summer, appliances such as your fridge, extractor fan and tumble dryer may be under increased demand due to warmer weather. You may also find yourself using appliances such as air conditioners or air purifiers more frequently. Show your appliances some love by cleaning freestanding fridge coils, emptying tumble dryer filters and washing extractor fan filters regularly. This can help your appliances run more efficiently.
Tips on how to clean these parts specifically:
- To clean your freestanding fridge and fridge freezer coils, first remove the plug, then locate its coils and remove any dust. You should also clean the surrounding areas before reassembling and plugging back in.
- For extractor fans, ensure the power is switched off before removing the filter, which may be clipped or screwed into place. The filter can be soaked in warm water with washing-up liquid and gently scrubbed, then left to dry fully before refitting.
- For tumble dryer filters, take it out the machine before rinsing under warm water to help to remove any residue, and let it fully dry before putting it back in.

Consider skipping the dishwasher drying cycle

Make the most of residual oven heat where possible
Run your appliances at night
Nighttime might just become your new favourite time to tackle chores. Running your appliances at night can be a simple and non-disruptive way to manage energy use during summer months. Energy rates may be lower overnight,[1] and so running appliances like dishwashers, washing machines and dryers (where possible) could result in lower costs. It may also help keep extra heat out of your home during the warmer parts of the day.
Carry winter habits into summer, and keep your home insulated
In the winter, good insulation can help reduce heat loss, while in the summer, insulation helps prevent heat from entering the home! A simple step could be to keep your blinds and curtains closed at the hottest time of the day. In winter, this can help keep heat in, but in summer it helps keep heat out, and lessen reliance on use of fans and air conditioners.

Try to wash clothes when you have a full load

Check your fridge at the recommended temperature
Check your fridge seal this summer with a simple cling film test
A quick kitchen test could help keep your fridge running efficiently this summer. Try the ‘cling film test’:
- Place a strip of it half inside and half outside the fridge, then close the door.
- If it slides out easily or falls free, then that section of your fridge is not sealed.
- A loose seal can allow cold air to escape, and warm air to enter, meaning your fridge may be using more energy to maintain a steady internal temperature.
