Households are facing a brand new summer sting, with new data revealing that half (52%) of Brits were forced to shell out extra cash just to cope with the recent June heatwave.

New data also revealed 56% of UK adults are gripped by "heatwave anxiety" as sudden summer spikes lead to unexpected outgoings.

The YouGov study, commissioned by money-saving site MyVoucherCodes, exposes the true cost of Britain’s changing weather. It reveals that the soaring temperatures are not just draining the UK's water supplies; they are draining our wallets, too.

The Shock Cost of Staying Cool

According to the findings, the vast majority of the nation saw their usual outgoings skyrocket during June’s heatwave. Brits scrambled to buy fans, paddling pools, and extra refreshments to beat the heat.

● 52% of households admitted to spending extra money as a direct result of the June heatwave.

● Just over one fifth (21%) blew over £50 on heatwave essentials.

● Around 20% of hard-pressed Brits estimate they splashed out more than £100 just to stay cool.

'Heatwave Anxiety' Sweeps the Nation

It isn't just our bank balances suffering; the unpredictable British weather is taking a massive toll on the nation's peace of mind.

A staggering 56% of UK adults confess they now suffer from anxiety at the thought of more frequent or severe heatwaves hitting the country. Within that group, 17% describe themselves as "very anxious" about future weather extremes, while 39% are "somewhat anxious."

Shopping and lifestyle expert Sarah-Jane Outten said, "We’re used to worrying about the 'heating tax' in the winter, but these figures show that summer is becoming just as expensive for British families. Slipping into extra spending just to stay comfortable or keep the kids entertained during a sudden heatwave is putting an unexpected dent in household budgets”

Sarah-Jane goes on to share her tips on how to save money and keep cool during the next heatwave.

● Beware of scams - This year especially, I have noted several scams when it comes to purchasing aircon units or fans online. If it’s a website that’s unfamiliar to you, check if it's legit. Is there a padlock on your browser address bar? Does this website normally sell aircon units or fans? And if you are still unsure, copy and paste the URL into Google's Safe Browsing Site Status. Finally, pay with a credit card if you can; this way, there is a chance you will get your money back if your purchase was a scam.

● Close your windows - Leave windows, blinds and curtains closed during the hottest part of the day. This is generally between 11 am and 4 pm.

● Unplug ‘phantom’ heat sources - Electrical devices that generate heat, even in standby mode. Some of the biggest culprits are game consoles, desktop computers and chargers.

● Swap the oven for the microwave - Using the oven in a heatwave is a bad idea. It will heat your kitchen fast. If you need to cook, use the microwave or airfryer. This saves money too.

● Ditch bottled water - instead use a refillable water bottle. Not only does this save money, but it’s better for the environment.
