“An estimated 4m homes in the UK now have air conditioning, double the figure from three years ago as Britons complain of ‘unliveable’ conditions during high temperatures.

Portable units with power ratings around 1kW are slightly more common than the more powerful built-in versions that can guzzle 2.7kW of power – more than an electric oven.

Experts suggest the increase in ownership is the result of more people working from home and rising summer temperatures. Some of the UK’s warmest summers have been in recent years, and the UK’s hottest day was in July 2022, when temperatures hit 40C.”
