When a bold pitch on The Apprentice suggested that air conditioning (AC) has become a necessity due to longer, hotter UK summers, it sparked nationwide debate. Many viewers began to wonder—are British summers truly changing, or was this just TV sensationalism?
At Seasonal Control, we decided to investigate these claims using the latest climate data from authoritative sources like the Met Office and IPCC, and examine the implications for air conditioning in UK homes and businesses.
The short answer: Yes. Recent studies confirm significant extension of UK summers. The Met Office indicates that average UK temperatures have risen approximately 1°C since the 1960s. This warming has resulted in an extended warm season, with summer-like conditions now lasting about one month longer than they did 50 years ago. In fact, the growing season in England is currently 29 days longer compared to the 1961–1990 average.
Notably, eight of the ten hottest years in UK history have occurred within the past decade, with 2022 being the warmest year ever recorded. Such statistics clearly highlight a real, measurable shift in the UK’s climate.
Yes, unquestionably. Heatwaves are not only becoming more frequent but also increasingly severe. The UK’s highest-ever temperature of 40.3°C, recorded in July 2022 at Coningsby, Lincolnshire, was unprecedented and exceeded the previous record of 38.7°C (set in 2019) by 1.6°C.
The Met Office has even issued its first-ever Red Extreme Heat Warning in recent summers, underscoring the increased severity and associated health risks of these heatwaves.
These increasingly common heatwaves carry significant health and economic costs. In 2022, England and Wales recorded approximately 2,985 excess deaths attributed directly to heat stress, marking a significant rise from previous years. Economically, heatwaves disrupt transportation infrastructure, including melting roads and warped rail tracks, and decrease workplace productivity. The London School of Economics estimates heat-related productivity losses could cost the UK economy around £6.1 billion annually by 2050.
Given these trends, air conditioning is becoming essential rather than a luxury. Currently, less than 5% of UK homes have air conditioning installed, a stark contrast to the U.S., where over 90% of homes have AC. Yet, following the 2022 heatwaves, sales of portable air conditioners surged dramatically, indicating growing recognition of AC’s importance in maintaining comfort, productivity, and health during extreme heat.
However, increased air conditioning adoption presents sustainability challenges. The potential increase in electricity demand could significantly impact carbon emissions unless balanced with renewable energy use.
Fortunately, sustainable solutions exist that can either complement or replace the widespread use of air conditioning:
The Apprentice contestant accurately highlighted a genuine and pressing issue. UK summers are indeed becoming longer and hotter, making effective cooling a growing necessity. However, the optimal approach combines air conditioning with sustainable building practices and efficient technology to manage heat responsibly.
