The 'viral TikTok heatwave trick' that could invalidate your home insurance
Safety experts warn that viral cooling hacks circulating during UK heatwaves, such as placing ice or cold water in front of fans, risk causing electrical damage that could void home insurance claims. Go Compare and Electrical Safety First highlight dangers from moisture reaching electrical components and caution against other risky trends, including leaving windows open overnight and using cheap cooling devices unsafely. Recommended alternatives include closing curtains during peak heat, ventilating at cooler times, and using electrical appliances responsibly to reduce indoor temperatures without jeopardising insurance coverage.
