Supermarkets Design Fridges for Hotter UK Summers

Marks & Spencer is buying new fridges built to work in extreme heat—up to 45°C—with better-sealing doors to keep cool air in. The CEO says this isn't temporary; he expects severe heat to recur regularly. A nine-day heatwave recently emptied shelves of ice-cream. Sainsbury's is spending hundreds of millions on similar upgrades, showing all major UK grocers are preparing for permanent climate shifts.
