Rising UK heatwaves are increasing demand for air conditioning, but heavy reliance on AC risks higher energy use, emissions and inequality. Survey data shows rapid growth in home cooling, driven by record temperatures. Passive cooling measures such as shading, natural ventilation, and reflective surfaces offer low‑cost alternatives and are widely used in southern Europe. Behavioural adaptation and public risk awareness are also essential, as UK culture still treats heat as benign. Current UK energy policy overlooks summer overheating, requiring reforms that integrate climate risks and prioritise reducing cooling demand before relying on mechanical systems.
