Air conditioner ownership in the United Kingdom has doubled in the past three years, reaching about four million homes, according to recent data. The surge is attributed to increasing heatwaves, higher summer temperatures, and the growing trend of working from home. In July 2022, the country recorded its highest-ever temperature of 40 degrees Celsius, prompting many residents to describe their homes as unlivable during extreme heat.

Cooling company Debonair Cooling reported rising demand from both old and new homeowners, with installation costs averaging £2,500 per room. The UK’s Climate Change Committee warned that climate change could make air conditioning essential in most homes by 2050, as traditional cooling methods like curtains or shade trees will no longer suffice. The committee also recommended installing cooling systems in all care homes and hospitals within the next decade.

However, experts noted that air conditioning increases electricity use and greenhouse gas emissions, accounting for about 4% of global emissions. Analysts suggest that combining heat pumps with solar power could offer a more sustainable cooling solution in the future.
