British houses were not built for heat. They were built for grey skies and drizzle and the kind of weather where you’re glad of thick walls and carpet. So when summer actually arrives — properly arrives, the kind where it’s still 27 degrees at 10 pm, and your bedroom is basically a radiator — most of us are completely unprepared for it. No AC, maybe a fan that moves hot air around slightly faster than it was already moving, and the creeping realisation that this is just going to be the temperature now for a while. The good news is you don’t need to spend anything to make a meaningful difference to how your home feels. You just need to work with the house instead of against it.
Block The Heat Before It Gets In
The single most effective thing you can do is stop the sun from heating your rooms up in the first place, rather than trying to cool them down after it already has. Close the curtains and blinds on any windows that get direct sunlight during the day — south- and west-facing rooms especially. It feels counterintuitive to close everything up on a sunny day, but the difference it makes is significant. A room that’s had its curtains closed all day is noticeably cooler than one that’s been in full sun. Blackout curtains are the most effective, but anything that blocks direct light helps. Do this before the sun hits the window, not after.
Open Everything At The Right Time
Cross ventilation is your best free tool, and most people don’t use it properly. The goal is to create airflow through the house by opening windows and doors on opposite sides so air moves through rather than just sitting there. The timing matters, though — open up in the early morning when the outside air is actually cooler than inside and again in the evening once the temperature drops. During the hottest part of the day, keep everything closed. You’re essentially trying to flush the cool air in and lock it there before the heat of the day builds up. Opening windows at midday when it’s 30 degrees outside just lets the hot air in.
Use Your Fan Smarter
If you’ve got a fan, it can do more than just oscillate, hopefully in the corner. Pointing it at a doorway or window rather than directly at yourself helps move air through the room more effectively. The other one — and it genuinely works — is putting a bowl of ice or very cold water in front of it. The air passing over the cold water drops in temperature before it reaches you. It’s not air conditioning, but it’s noticeably cooler than a fan alone, and it costs nothing if you’ve already got ice in the freezer. At night, if the outside temperature has dropped below the inside temperature, put the fan in the window facing inward to pull the cooler air in.
Keep Heat Sources Off During The Day
Your oven, your tumble dryer, your dishwasher — all of them generate heat when they run, and that heat goes somewhere and that somewhere is your house. On hot days, cook outside if you can, or eat things that don’t need cooking. If you need to use the oven, do it in the morning or late evening. Run the dishwasher and dryer overnight. It sounds like a small thing, but appliances generate more ambient heat than most people realise, and on a day when the house is already struggling to stay cool, every bit of additional heat makes a difference. This is also just cheaper to run overnight in general, so it’s a habit worth getting into regardless.
Cool Yourself, Not Just The Room
There’s a limit to how much you can change the temperature of a whole house without spending money on equipment. What you can do is make yourself feel cooler within it. Cold water on your wrists and the back of your neck works quickly because the blood vessels are close to the surface there. A lukewarm shower rather than a cold one — counterintuitively — is more effective at bringing your body temperature down because very cold water causes your body to retain heat to compensate. Loose cotton or linen, eating lighter meals that don’t require your body to work hard to digest them, and staying hydrated. The house might still be warm, but you can feel significantly more comfortable in it.
Make Your Bedroom Survivable At Night
Night is usually the worst of it. The house has absorbed heat all day, and now you’re trying to sleep in it. Swap your duvet for a cotton sheet. Put your pillowcase in a bag and stick it in the freezer for twenty minutes before bed. If you’ve got a hot water bottle, fill it with cold water instead. Keep a glass of cold water next to the bed. Crack the window if the outside air has cooled down and use the fan in the window method to pull it in. None of this is as good as air conditioning, but it’s the difference between lying there sweating and staring at the ceiling and actually getting some sleep, which at a certain point is all you’re asking for.
