Lee Jackson Air Conditioning experienced a record spike in website traffic for air-conditioning installation-related enquiries during the May 2026 heatwaves, which brought the hottest spring temperatures ever recorded in the UK.
Nottingham-based air conditioning specialists Lee Jackson Air Conditioning reported an 838% increase in installation enquiries to its website during May 2026.
During this time, an unprecedented early heatwave saw homeowners and businesses in search of relief from temperatures which reached 32°C in the local area.
In this post, our team will reveal the main conclusions of the 2026 heatwaves and subsequent increase in air conditioning enquiries to our website.
May 2026 Heatwaves UK: A Recap
During the final week of May 2026, the Met Office forecast highs of 35°C across an area covering Lincolnshire, the Midlands and westwards into East Anglia during the Bank Holiday weekend, describing the conditions as an exceptional spell of warmth for May.
Sustained highs of 32°C were then forecast for the East Midlands across the days that followed, with residents across Nottinghamshire, Leicestershire and Derbyshire enduring successive days without meaningful overnight relief.
The UKHSA issued heat-health alerts for the East Midlands from 22 May, escalating them from yellow to amber within hours as temperatures continued to climb.
Elsewhere across the UK on 25 May, a new UK daily temperature record for spring and May was provisionally broken, with 34.8°C recorded at Kew Gardens, exceeding the previous record of 32.8°C, which had stood since 1922, by a full two degrees.
This was not the first time the East Midlands had found itself at the centre of a historic heat event. During the 2022 heatwave, Nottinghamshire temperatures peaked at 40.1°C, with Derbyshire recording 39°C and Leicestershire reaching 38.3°C.
The fact that the region was again under amber heat-health alerts just four years later, this time in May rather than the height of summer, underlines how quickly the threshold of what counts as exceptional is shifting.
Our Thoughts On The Sharp Increase In Air Conditioning Enquiries As Professional Installers
Heatwaves are arriving earlier in the year:
The May 2026 event was not a summer heatwave. It arrived during the Bank Holiday weekend, affecting households and businesses that had not yet given a thought to cooling. Many of the people contacting Lee Jackson during the spike had assumed they had weeks, if not months, before conditions became uncomfortable. The 2026 heatwave demonstrated that the window for proactive planning is shrinking, and that waiting for July to think about air conditioning is no longer a safe assumption.
Overnight temperatures are making heat unmanageable:
Previous UK heatwaves were survivable largely because nights brought relief. Open a window, let the house cool down, and the following day became bearable. Tropical nights remove that option entirely. When temperatures remain above 20°C through the night, properties retain heat, sleep becomes impossible and the cumulative effect across several days becomes a genuine health risk. It is this feature of the 2026 event, more than the daytime peaks, that has driven the most urgent enquiries to Lee Jackson.
The urban heat island effect makes cities significantly hotter:
Nottingham, Leicester and Derby all sit within the urban heat island effect, where dense building stock, roads, car parks and limited green space cause cities to retain heat considerably longer than surrounding rural areas. Residents in terraced housing or flats with limited ventilation, and office workers in older commercial buildings without modern HVAC systems, feel the effects of a heatwave more acutely and for longer than national headline temperatures suggest.
Working from home has changed the equation:
The shift to hybrid and remote working means that for a significant proportion of the workforce, the home is now also the workplace. During a heatwave, it creates a situation where there is no air-conditioned office to escape to. Productivity drops, concentration suffers and in some cases, the working environment becomes genuinely unsafe. Several of the commercial enquiries Lee Jackson received during May 2026 came from employers whose home-working staff had flagged concerns, highlighting that the duty of care around temperature now extends well beyond the office door.
Health alerts have made the risk impossible to ignore:
Amber heat-health alerts covering the East Midlands for five consecutive days in May 2026 marked a shift in how people perceive summer heat. These are not advisory notices recommending sun cream and extra water. They carry specific guidance for the NHS and local authorities and signal a meaningful risk to health, particularly for older residents, young children and those with existing conditions. For many households that received those alerts, the response was to start looking at permanent solutions rather than relying on fans and open windows.
Records are being broken too regularly to dismiss as anomalies:
In 2022, a 40.3°C national record felt like a landmark moment, a line crossed that might not be crossed again for decades. By May 2026, the UK had broken its spring temperature record twice in consecutive days. The Met Office has confirmed that what was once a one-in-100-year event is now a one-in-33-year event. For homeowners and businesses making long-term decisions about property and infrastructure, that shift in probability changes the investment calculation around air conditioning fundamentally.
Installation lead times mean reactive decisions come too late:
One of the clearest practical lessons from the 2026 heatwave is that air conditioning cannot be installed in response to a heatwave. Survey, specification, equipment supply and installation all take time, and during peak demand periods, that timeline extends further. The customers currently booking consultations with Lee Jackson are those who experienced May 2026 without cooling in place and have decided not to repeat the experience. Acting before peak summer demand arrives means shorter lead times, more flexibility on scheduling and a system that is fully commissioned before it is needed most.
