No Air Con? 5 Simple Ways to Keep Your Home Cool During a Heatwave
When temperatures rise, keeping your home comfortable can feel like a full-time job, especially in the UK where air conditioning still isn’t the norm. The good news? You don’t need expensive gadgets or major home upgrades to make a noticeable difference.
A few simple tweaks to how you manage light, airflow and heat can help keep indoor temperatures down and make hot days (and even hotter nights) far more bearable.
Here are five easy ways to keep your home cooler during a heatwave.
1. Keep blinds and curtains closed during the day
It might feel natural to throw open the curtains and windows when the sun is shining, but direct sunlight can quickly turn rooms into greenhouses.
Closing blinds, curtains, or shutters during the day helps block solar heat before it enters your home. South-facing rooms tend to heat up fastest, so prioritise those if you can and make sure you’re closing them early on before the temperatures peak.
Blackout curtains or thermal linings can be especially effective at reducing heat gain as long as they’re not too heavyweight.
2. Open windows for natural ventilation
Timing matters when it comes to ventilation.
During the hottest hours (usually late morning to early evening), keep windows closed to stop warm air coming in. Then, once temperatures drop in the evening or early morning, open windows wide to let cooler air circulate.
If possible, create a cross-breeze by opening windows on opposite sides of your home. Even a gentle airflow can make a big difference.
3. Switch off heat-generating appliances
Many everyday appliances quietly add heat to your home.
Ovens, tumble dryers, dishwashers, and even laptops can all contribute to rising indoor temperatures, particularly in smaller spaces.
Try to:
Cook earlier in the day or opt for no-cook meals
Air dry laundry instead of using the tumble dryer
Switch electronics fully off rather than leaving them on standby
Small changes can help reduce unnecessary heat buildup (and it help the environment which, to be frank, is why we’re having heatwaves more regularly now)
4. Use fans more effectively
Fans don’t lower room temperature but they do help your body feel cooler by improving airflow.
To make them work harder, try placing a bowl of ice or a frozen water bottle in front of the fan. This can help create a cooler breeze. At night, position a fan near an open window to help pull cooler evening air into the room.
Ceiling fan? Make sure it’s rotating anti-clockwise in summer to push cool air downward.
5. Swap heavy fabrics for lightweight natural materials
We all know to swap out our duvets when the warmer weather comes, but did you know textiles can hold far more heat than you might realise, even when we’re not snuggled in them.
Heavy throws, velvet cushions, thick rugs and dense bedding can make rooms feel warmer and stuffier, especially during prolonged hot weather.
Switching to lighter, breathable fabrics can instantly help a space feel fresher. Opt for natural materials such as cotton, linen or bamboo for bedding, cushion covers and throws, as these fabrics tend to breathe better and trap less heat than synthetic alternatives.
Store away thick blankets and winter bedding and roll up heavy rugs in sun-facing rooms. It’s a simple seasonal switch, but one that can make bedrooms and living spaces feel noticeably cooler.
