How to Stay Cool in a Heatwave Without Spending a Fortune

British summers, eh. Three weeks of drizzle, then suddenly it's 34 degrees and your flat has turned into an oven. Nobody is prepared. Nobody is okay.

If you're trying to stay cool without blowing your budget on a portable air con unit that costs more than your monthly shop, you're in the right place. Here are some genuinely useful tips for surviving the heatwave without spending a fortune.

Block Out the Heat Before It Gets In

This one's free and it works. Close your curtains and blinds during the day, especially on south and west-facing windows. It sounds counterintuitive (dark room = miserable), but keeping sunlight out can drop your room temperature by several degrees. Open everything up in the evening once the air outside cools down. You're basically doing the opposite of what your instincts tell you, but trust the process.

Use Your Fans Smarter

If you've already got a fan, brilliant. Make it work harder by placing a bowl of ice or cold water in front of it. The air blows over the cold surface and feels noticeably cooler. It's the closest thing to air con you'll get for about 50p.

No fan? Before you panic-buy one at three times the normal price, check the deals feed here on Rapid Savings. During heatwaves, fans sell out fast, but members often spot restocks and flash sales before they're gone. Worth a look before you pay over the odds.

Keep Your Body Temperature Down on the Cheap

Cold showers are obvious but genuinely effective, especially before bed. If you can't face a full cold shower, run cold water over your wrists and the back of your neck. There are pulse points there that cool your blood down quickly.

Freezing a damp flannel and draping it over yourself while you sleep is a bit of a faff but works surprisingly well. Also, ditch the duvet and swap to a single cotton sheet. If you're still roasting, a bag of frozen peas on your feet isn't the most glamorous cooling strategy, but it does the job.

Think About What You're Eating and Drinking

Hot oven meals make your kitchen unbearable. Shift to salads, wraps, cold pasta, and anything that doesn't require an hour at 200 degrees. Beyond just comfort, it keeps your energy bills down too, which during summer is genuinely worth thinking about.

Drink water constantly. This sounds obvious but most people don't drink enough during a heatwave and then wonder why they feel awful. Add some ice and a slice of lemon if you want to make it feel like more of a treat. You're not missing out, I promise.

The Best Free Cooling Spots in Your Area

Supermarkets, libraries, and shopping centres are air conditioned and free to walk around. If you're really struggling at home, especially if you're vulnerable to the heat, there's no shame in spending a couple of hours somewhere cool. Libraries in particular are brilliant for this, quiet, comfortable, and completely free.

Some councils publish a list of official cool spaces during heatwaves. Worth checking your local council's website to see if yours does.

Don't Get Ripped Off on Cooling Gear

Heatwave season brings a wave of inflated prices on fans, paddling pools, and sun cream. Buy what you need quickly and don't assume the first result you see is a good deal. If you're shopping for home cooling gear, check Rapid Savings first and set up a deal alert via your settings so you're notified when something worth buying actually goes on sale.

We rebuilt this platform in 2026 specifically so deal hunters could get ahead of these moments rather than just react to them. A heatwave is exactly the kind of event where having the right alerts in place saves you real money.

Stay Cool, Not Skint

Heatwaves in the UK are chaotic and expensive if you're not prepared. But with a bit of forward thinking and a few free tricks, you can get through it without your bank account suffering alongside you. Block out the sun, cool your body directly, eat cold food, and use the community here to find any gear you need at a fair price.

Stay cool out there. Literally.
