UK supermarkets are responding to rising temperatures by installing advanced cooling systems designed to cope with heatwaves. Waitrose has joined Marks and Spencer (M&S) in implementing Mediterranean-style refrigeration technology that integrates heat pumps with conventional refrigeration units.
This cutting-edge system enables fridges to function efficiently in outdoor temperatures up to 48°C, far surpassing earlier equipment capabilities. Tina Mitchell, retail director at Waitrose, commented on the move: “This summer shows our latest refrigeration technology is more resilient than older equipment, and we’re continuing to accelerate investment across our estate.” She added, “As hotter summers become more common, we’re continuing to invest in technology to keep products at peak freshness, help our stores perform reliably and improve energy efficiency.”
M&S chief executive Stuart Machin acknowledged the challenges posed by recent heatwaves, stating, “There is no doubt we were struggling. Now we’re investing in equipment in our stores to deal with temperatures of 45°C. We’re reviewing all our refrigeration as well.” Speaking at the M&S annual meeting in London, he emphasised that these investments reflect a future where higher temperatures are anticipated.

These developments coincide with a severe environmental situation, as half of England is currently experiencing drought conditions. According to the Environment Agency, July is on course to be the driest month on record following severe winter floods. This “flash drought” has emerged rapidly due to unusually low rainfall combined with high temperatures.
Helen Wakeham, director of water at the Environment Agency and chair of the National Drought Group, warned of the serious consequences: “The hot and dry weather means we are currently using water faster than nature can replenish it. A second consecutive summer drought is an exceptionally serious situation and one that will have long-lasting impacts on our environment, wildlife and the economy.” She urged the public to conserve water, noting, “We want everyone to stay safe and hydrated during the hot weather but every drop we can save is a drop more for nature and agriculture.”
Paul Tompkins, deputy president of the National Farmers’ Union, highlighted the broader implications, stating, “This drought announcement should matter to everyone. Water is a vital ingredient in food production, and without a secure supply, we cannot build resilient farm businesses or strengthen the country’s food security.”
