Summer energy-saving tips: How to keep your house cool in summer

1. Close the curtains in hot weather
Make sure sunlight and heat can’t get into your house, so you don’t have to waste energy on air conditioning or a fan. Keeping blinds and curtains closed when you’re out during the day will keep the room cool, making it easier to sleep at night.
Keep windows closed during the day so the hotter air stays out. You can then open them at night, when it’s cooler outside.
2. Dry clothes without a tumble dryer
Tumble dryers – especially older models – are notoriously energy-hungry. And in summer a drying rack or washing line can do the job just as quickly.
3. Keep your fridge ¾ full
Your fridge works most efficiently when it’s 3/4 full. If you pack too much into it, your fridge will have to work harder to circulate cold air. If it’s empty, meanwhile, warm air will rush in when you open the door.
If you don’t want to spend a fortune at the supermarket, the Energy Saving Trust recommends filling your fridge with bottles of tap water. That way you’ll also have cold drinks to hand on hot days.
4. Look after your appliances
If ice builds up in your freezer, the motor has to work harder, using more energy. If you regularly defrost your freezer, the motor will work more efficiently, which means your freezer will last longer.
Also, remember to dust the back of your fridge and freezer, so the heat can escape.
Here are some other ways to reduce your fridge and freezer’s energy consumption:
• Keep them in the coolest part of the room, away from the oven
• Leave enough room for hot air to escape from the back
• Always let hot food cool down before putting it away
• Avoid leaving the door open in-between jobs
5. Buy an aerated shower head and taps
Lots of us use far more water in summer as we water the plants and take extra showers. A good way to limit your water use is to buy aerating attachments for your shower head and taps. These blend water with air to create larger droplets, allowing you to use less water (and less energy to heat it) without feeling the difference.
Check your water company’s website for more water-saving tips. Some suppliers even offer free water-saving devices, and rewards for using less water.
6. Swap traditional light bulbs for LEDs
LED light bulbs last longer, give off more light, and use less electricity than traditional bulbs. And since they don’t give off heat, they’ll help your home stay cooler on sweltering evenings.
Still not convinced? Switching to LED light bulbs could cut 40kg* from your annual carbon-dioxide emissions, and save you up to £13 per bulb, per year*. If you’re worried that LED bulbs give off too stark a light, look for ‘warm white’ or ‘soft white’ bulbs, which have a cosier effect. See the latest LED lighting.
7. Get the most out of your smart meter
Smart meters tell you how much energy you’re using, as you use it. This helps you make energy-conscious decisions, which can lower your bills and your carbon emissions, too.
