When the next heatwave strikes, will your workplace be ready – or will your people, customers, and equipment be left struggling in the heat? Across the UK, thousands of commercial buildings face the same problem: they were never designed for the kind of prolonged, intense heatwaves we now see almost every summer.
In this blog, we’ll explore why so many UK workplaces overheat during the summer, and how temporary cooling hire with Andrews Air Conditioning provides a fast and flexible fix when your building can’t cope.

What is the UK’s Heatwave Problem?
Many older buildings were designed to retain heat – not deflect it:
Older buildings prioritised keeping warmth in during winter, but this backfires in summer. With thick walls, limited ventilation, and outdated systems, these buildings trap heat, creating stuffy and uncomfortable environments that are difficult to cool down.
Offices, schools, retailers, and more often lack built-in air con:
Unlike other climates, UK commercial buildings rarely include permanent AC as standard. Many workplaces rely on opening windows or small fans, which are no match for modern heatwaves.
Glass-heavy, insulated buildings create “oven” conditions:
Modern energy-efficient buildings with large glass façades and heavy insulation perform well in winter but turn into heat traps in the summer, especially when exposed to direct sunlight.
Heatwaves are becoming longer and hotter:
2022 and 2023 broke temperature records, and forecasts predict even hotter spells in 2025 and beyond. What was once a rare event is now a recurring business challenge.

What is the Impact on Businesses?
Overheating staff:
Studies show that heat reduces concentration, increases fatigue, and slows reaction times, which is bad news for productivity and staff wellbeing. Uncomfortably hot conditions can also lead to sick days or early finishes.
Critical equipment faces heat-related risks:
IT server rooms, refrigeration units, and stock storge areas are sensitive to temperature rises. Without adequate cooling, overheating can lead to downtime, damage, and costly repairs.
Customer experience suffers:
Heat drives customers away from overheated shops, restaurants, gyms, and salons. No one lingers when the environment is stifling.
Health and safety obligations under HSE guidance:
Businesses have a legal duty to maintain reasonable workplace temperatures. Prolonged heat risks breaching these standards and damaging your duty of care.

Why Permanent AC Isn’t Always the Answer
Permanent air conditioning might seem like the answer, but for many businesses, it isn’t practical. Installation costs are high, and the disruption from planning permission and building works can be significant – especially when systems are only need for a short period each year.
Listed buildings, protected sites, and short-term leases often entirely rule out permanent solutions. For most workplaces, the return on investment simply isn’t there. That’s why temporary cooling hire, like our air con hire, is the smarter choice. It’s fast to deploy, flexible in duration, and cost-effective for seasonal demand.
