When temperatures climb into the thirties, homes can quickly turn into heat traps – and many of us unknowingly make them even warmer than they need to be. The good news? A few simple changes can make a noticeable difference, with no renovations required.
Most homes in the UK weren't built to withstand intense heat, leaving renters with limited options for staying cool. Homeowners may be able to invest in permanent solutions such as heat pumps or external shading, but these upgrades are often costly.
That's why we asked property and interiors experts to share their best advice for keeping your home cool without making permanent changes. From everyday habits to simple styling swaps, these renter-friendly interventions can help create a cooler, more comfortable indoor environment throughout summer.
1. Install light, reflective window treatments
One of the most effective ways to keep your home cool is to stop heat from entering in the first place.
'Blackout curtains aren't just for winter,' says Wayfair's art director Olivia Sauerwein. 'They can help block direct sunlight and reduce heat build-up indoors, particularly in south-facing rooms that receive sunlight throughout the day.'
If you prefer darker curtains, choose a style with a white or metallic lining facing the window. This reflects the sun's rays rather than absorbing heat into the fabric.
2. Minimise the use of heat-generating appliances
Heat builds quickly in the summer, and you can avoid adding to it by turning off – or limiting the use of – certain electric appliances. 'It is important not to generate any further heat, so make sure your central heating is turned off,' says Jack Malnick, managing director of property-buying service Sell House Fast.
'Unplug all devices from any sockets to reduce standby heat. Consider cooking at cooler times of the day or choose meals that don't require an oven or hob that creates additional heat.'
3. Switch to breathable bedding
Changing your bedding is one of the quickest ways to stay comfortable during warmer nights. Choose moisture-wicking materials like linen or cotton.
'Swap heavy bedding for lightweight, breathable alternatives such as cotton sheets, cooling pillows and lightweight duvets,' Olivia recommends.
'Natural fibres are more breathable and can help regulate body temperature, making it easier to sleep comfortably during hot weather.'
4. Choose furniture that supports airflow
Designing interiors with the climate in mind is becoming increasingly important. One design choice that can make a big difference in the summer is choosing furniture that supports airflow. 'A sofa, armchair or bed that sits flush to the floor can essentially act as a solid mass trapping heat at ground level,' a spokesperson for online furniture retailer Castlery tells us.
'In contrast, furniture elevated on legs promotes better air circulation. This is particularly effective in the bedroom, in tandem with a fan or air con, where a raised bed frame can provide much-needed relief during humid, stuffy summer nights.'
5. Rethink your layout
Big pieces of furniture can obstruct airflow and make rooms feel stuffier than they are.
'Where possible, move bulky furniture slightly away from windows and doorways to allow air to circulate more freely,' says Amthal Karim, head of design at online retailer Furniture And Choice.
'Even creating a little extra floor space can make the room feel less enclosed during hot weather.'
6. Store away heavy soft furnishings
'Soft furnishings also influence how a home responds to heat,' says Sergiu Tulbur, head of product innovation and design at OPA Living. 'Thick curtains, dark fabrics and densely upholstered furniture absorb and retain warmth throughout the day, releasing it slowly into the evening.'
For an instant seasonal refresh, swap out heavy throws, cushions, curtains and bedding for lighter-coloured fabrics made from breathable natural fibres.
7. Don't underestimate the power of houseplants
Houseplants won't lower the temperature dramatically, but they can make interiors feel fresher and contribute to a more comfortable indoor climate.
'Houseplants add freshness to any room and can make the space feel more inviting,' says Amthal. 'Just remember to keep them out of strong afternoon sun during a heatwave and water them regularly.'
8. Pop doorstoppers around your home
While it's best to keep windows closed during the hottest part of the day when it's hotter outside than indoors, keeping internal doors open can improve airflow throughout your home. Use doorstoppers to prevent them slamming shut.
'Keeping doors open allows air to circulate through the home, helping to prevent warm, stale air from becoming trapped in individual rooms,' explains Jack.
'When combined with open windows or fans, it can help create a cross-breeze that naturally improves comfort. This is particularly useful for renters because it requires no permanent changes or equipment, making it an easy, low-cost way to improve airflow in hotter weather.'
