Marks & Spencer has made a strategic move to upgrade its refrigeration systems, investing in equipment that can function effectively at temperatures up to 45C. This significant investment comes as a response to the challenges faced by the retailer during last month's record-breaking heatwave, which saw provisional highs reach 37.7C – just shy of the all-time record of 40.3C set in 2022. The UK is on track for its third summer heatwave this week, with extreme temperatures projected to persist, making businesses' preparedness for climate change a pressing concern.
The upgrades are expected to include improved doors that maintain cooler internal temperatures more efficiently in warmer conditions, among other features. Chief executive Stuart Machin acknowledged the retailer's struggles during the nine-day stretch of extreme heat and stated, "We're assuming it will get hotter" – reflecting M&S' proactive approach to future climate realities. Interestingly, the company also experienced a six-fold surge in demand for ice cream, with six product lines temporarily going out of stock due to the unprecedented level of sales.
Marks & Spencer is not alone in facing these challenges; other major retailers have reported difficulties with their cooling systems during the June heatwave. Simon Roberts, CEO of Sainsbury's, highlighted last week that staff and suppliers were working around the clock to manage refrigeration demands, with plans to invest hundreds of millions of pounds into new refrigeration kit for approximately 100 stores.
The move reflects a broader recognition across the retail sector that the UK's infrastructure needs to evolve to withstand the impacts of climate change. In May, the Climate Change Committee warned that the UK is built for a climate that no longer exists and requires urgent modifications to cope with global heating. By investing in climate-resilient infrastructure, retailers aim to ensure continuity of service and product quality for consumers as the country experiences more frequent spells of exceptionally hot weather.
