Brits have been warned to stock up their fridges and freezers this morning ahead of scorching temperatures expected to exceed 32°C in many areas. The UK is facing its third heatwave of the summer, with Oxfordshire forecast to reach 34°C and London 31°C today.
Amber Heat Health Alerts Issued
Amber heat health alerts have been issued for the East Midlands, West Midlands, East of England, London, South East, South West, Yorkshire and the Humber, and the North West. These alerts indicate a risk to health for vulnerable individuals.
The Met Office forecasts that several areas will climb above 32°C today, with Oxfordshire reaching 32°C at 1pm and many southeastern counties hitting similar highs just after midday.
Supermarket Fridge Systems at Risk
Les Roberts from Bionic's energy team explained: "Many supermarkets in the UK are likely to be operating with outdated fridge and freezer systems. Older systems are commonly designed to withstand temperatures up to 32°C, making them ill-equipped to deal with the increasing number of heatwaves we’re experiencing in Britain."
During the previous heatwave on June 24, refrigeration disruption left shelves bare at Tesco and M&S branches, including Tesco in Haslingden, Crewe, and Altrincham. Printed notices appeared on fridges and freezers as customers encountered empty aisles.
How Heat Affects Refrigeration
Roberts added: "Once temperatures exceed the threshold they are designed for, the compressor has to work much harder to keep things cold. Over time, this extra strain can cause the system to overheat, wear out more quickly, and eventually break down. Therefore, these issues are likely to recur until systems are updated."
With temperatures predicted to surpass 32°C from 1pm onwards, Brits are urged to make essential purchases this morning to avoid disappointment. Roberts advised: "That’s why we’re advising Brits to stock up on their refrigerated and frozen essentials ahead of heatwaves. As there’s a risk that you may find frozen and refrigerated aisles empty due to broken fridges, we recommend that you top up on anything you may need ahead of time, whether it’s your weekly food shop staples, barbeque supplies or ice creams. By planning ahead, you won’t have to miss out if your local supermarkets are faced with this common issue."
