Just because it’s boiling outside doesn’t mean your home has to follow suit.
Summer in the UK is never quite predictable. One minute it’s drizzle, the next it’s a full-blown heatwave. And when it’s the latter - especially if you live in a top-floor flat or a home with plenty of south-facing windows - the heat can linger indoors far longer than you'd like.
If you rent your home, you might not have air conditioning - but that doesn’t mean you have to melt your way through summer. With a few clever tricks and small daily changes, you can make your living space cooler, calmer, and much more comfortable - all without needing to touch the thermostat.
Here are five practical ways to cool down your home when the temperature rises.
1. Block out the sun (strategically)
It might sound obvious, but it’s one of the best practices: keeping the sunlight out in the first place is your best defence against a sweltering home. The part of this trick is knowing when to let the sun in and out.
In the morning, as the day heats up, draw your curtains or blinds across any sun-facing windows – especially those that get the strongest midday or afternoon light. This can significantly reduce indoor heat and make your home feel cooler during the day. Not all curtains are made from the same protective material, but even lightweight ones can help block the worst of the heat.
Once the sun shifts away from your windows and the air outside cools (usually in the evening), open up the windows to let the breeze flow through. Just remember to close them before bed if you're in an area prone to summer mosquitos.
2. Create a cross-breeze
Do you have two windows on opposite sides of your flat or house? Open them both and let the air work its magic.
Cross-ventilation is one of the most underrated cooling hacks around. Even if the breeze is light, opening windows that are across from each other creates a natural flow of air that can bring down indoor temperatures surprisingly fast.
If you’re in a one-sided flat (like many UK renters), try pairing an open window with an internal door left ajar - or create a ‘wind tunnel’ by propping open the front door safely for a few minutes. Even the slightest airflow will help you cool your place down.
3. Switch off the heat-makers
It’s easy to forget how much heat we generate just by living our everyday lives. Cooking dinner, running appliances, even switching on lights - it all adds to the temperature.
On warmer days, try to minimise unnecessary heat sources. Cook outside of peak heat hours if you can (early dinners can be your new friend) and opt for no-cook meals every now and then. You can also turn off lights in rooms you’re not using, especially if they’re older-style bulbs, which give off more heat than you might realise.
And that movie marathon that you’re watching from your laptop on the sofa? Maybe shift to the shady end of the room or give your tech a break for a while.
4. Go for light bedding and clever layers
If you’re tossing and turning at night, your bedding might be working against you. Swap out thick duvets and heavy layers for lighter, more breathable fabrics - even an empty duvet cover can do the trick during hot spells.
Where possible, leave your windows slightly ajar to help the air circulate. You can even dampen a flannel or small towel and keep it near your bed – the evaporating water can subtly cool the surrounding air. It’s an old-school technique, but it still works wonders.
5. Rearrange your space (temporarily)
Some rooms just hold on to heat. South-facing bedrooms, upstairs studies, or those sun-trap living rooms with the big windows can make you feel like you’re melting.
So, if one space becomes unbearable during the day, consider a temporary relocation. Got a cooler back room or a shady hallway? That could become your summer reading nook or afternoon work zone that will make your day better (and cooler).
In a house, consider sleeping downstairs if the upstairs bedrooms are too warm. In a flat, even moving your mattress away from the wall (especially external ones that soak up sun) can help. After all, it’s your space, so shift things around to get that soothing cool and homely feel.
In the end, staying cool isn’t just about physical comfort - it’s about feeling calm, well-rested, and able to enjoy your home without feeling like you’ve stepped into a greenhouse.
You don’t need expensive gadgets or structural changes to take the edge off a heatwave. Sometimes, a few practical tweaks - and a bit of trial and error - are all you need.
But comfort at home is also about how a space feels day to day - how it works for your lifestyle, how relaxed you feel in it, and how connected you are to your surroundings. Whether you’re renting in a bustling city flat or a quieter spot further out, there are simple ways to feel more settled and make your home truly yours.
