As the UK braces for a severe heatwave with temperatures soaring up to 39°C, experts recommend unplugging certain household appliances to reduce fire risks and save energy. The heat is expected to peak on Wednesday and Thursday, particularly affecting southern England and southeast Wales, with slightly cooler conditions by Friday.
Electrical devices such as hair straighteners, phone chargers, kettles, toasters, microwaves, TVs, computers, and entertainment systems have been identified as potential hazards during extreme heat. Hair straighteners, for instance, operate at high temperatures that may intensify with the soaring ambient heat. Similarly, tech specialists advise against overnight charging of phones, tablets, and laptops, suggesting instead to limit charging times to between one and three hours.
Kitchen appliances like kettles, toasters, and microwaves consume significant energy, and relying on standby mode contributes to higher electricity bills. Unplugging these devices completely is advised to ensure safety and affordability.

The heatwave also brings challenges beyond the indoors. Elevated overnight temperatures — known as Tropical Nights, where the temperature remains above 20°C — combined with high humidity, increase heat stress risks, especially in urban centers.
Moreover, Dorset & Wiltshire Fire and Rescue Service warns of heightened risks for heath and woodland fires. Barbecues and campfires are strictly prohibited in heathlands and open spaces, and local restrictions apply in many parks and campsites. Group manager Shaun Milton urges the public to be cautious: “We want people to enjoy the sunshine, but we do urge everyone to think about what they’re doing and perhaps amend their plans to stay as safe as possible.”
In response to the heat, schools, particularly older buildings with less efficient cooling, have implemented early opening of doors and windows to promote air circulation. However, closures are not usually advised, as most schools can manage the heat safely.
By unplugging high-risk appliances and following safety guidelines, households can protect themselves and contribute to a safer, more energy-conscious summer during this intense heatwave.
