Warehouse Cooling: Protecting Productivity, Stock and Staff This Summer
As UK summers get hotter, warehouse operators are finding that keeping indoor temperatures under control is no longer a “nice to have”. Rising heat inside large industrial buildings affects staff productivity, risks stock integrity, triggers HSE complaints, and can even shut down automated equipment. With summer 2026 already forecast to be warmer than average, now is the time for facilities managers and warehouse owners to review their cooling strategy — before temperatures climb.
At AKS Air Conditioning, we’ve been designing and installing commercial cooling systems across the UK for over 34 years. We’ve worked with logistics operators, distribution hubs, e-commerce fulfilment centres, and manufacturing warehouses. In this guide, we break down the real challenges of warehouse cooling and the practical options available to keep your operation running smoothly this summer.
Why Warehouse Cooling Matters More Than You Think
Warehouses are among the hardest buildings to cool. High ceilings, large floor areas, frequent door openings, heat-generating equipment, and solar gain through roof panels all combine to push internal temperatures well above the outside air. On a 28°C summer day, it is not unusual for warehouse interiors to reach 35–40°C or higher near roof level.
The consequences are measurable and commercial:
- Reduced productivity — research from the Health and Safety Executive shows worker output drops noticeably above 27°C, with significant fatigue and error rates above 30°C.
- Staff welfare complaints and turnover — while the UK has no legal upper temperature limit for workplaces, employers have a duty to provide a “reasonable” working environment.
- Stock damage — electronics, cosmetics, pharmaceuticals, food, beverages, and many chemical products have strict temperature tolerances.
- Equipment failure — automated pickers, conveyors, robotics, and charging stations for MHE (material handling equipment) all run less reliably in heat.
- Energy waste — overheating means refrigerated storage areas and server rooms work harder, driving up costs.
The Main Cooling Options for UK Warehouses
1. Destratification Fans
Hot air rises and collects at ceiling level, often 10–15 metres above the working floor. Destratification fans circulate this trapped heat back down, evening out temperatures and reducing heating loads in winter too. They are low cost and low energy, but on their own they are not a true cooling solution.
2. Industrial Evaporative (Adiabatic) Cooling
Evaporative coolers draw warm outside air through water-saturated pads, dropping the temperature by 8–12°C before pushing it into the warehouse. They use a fraction of the energy of refrigerated air conditioning and work well in well-ventilated buildings. The downside: they add moisture to the air, which is unsuitable for stock that needs controlled humidity (such as paper, electronics, or sensitive dry goods).
3. High-Capacity Air Conditioning (VRV/VRF and Rooftop Units)
For full temperature and humidity control, particularly for mezzanine offices, pick-and-pack areas, pharmaceutical storage, or robotics zones, refrigerated air conditioning remains the gold standard. Systems from Daikin and Mitsubishi Electric — both of whom we are approved partners with — offer large-scale commercial units designed specifically for industrial environments.

4. Mechanical Ventilation and Heat Recovery (MVHR)
In some warehouses, the real issue is stagnant, warm, contaminated air rather than pure heat. A properly designed mechanical ventilation system can extract hot air, bring in fresh tempered air, and maintain safer air quality for staff. Often the best outcome comes from combining ventilation with targeted cooling.
5. Zoned Cooling Strategies
Cooling an entire 10,000-square-metre warehouse to 20°C is rarely commercially sensible. A smarter approach is zoned cooling — focusing investment on the areas that matter most: offices, mezzanines, charging zones, cold storage airlocks, and staff welfare areas. This delivers the productivity and compliance benefits without the eye-watering energy bill of a whole-building refrigerated system.
What Should Warehouse Operators Do Now?
If your warehouse struggled in the heat last summer, the worst decision is to wait and see. Lead times on large commercial projects stretch during peak season, and running into June without a plan usually means paying premium rates for reactive installations. We recommend the following steps:
- Audit last summer’s impact. Review temperature logs, productivity data, staff complaints, and stock losses.
- Identify priority zones. Where did heat cause the biggest commercial damage?
- Commission a professional site survey. A qualified engineer should assess building fabric, solar gain, existing ventilation, heat loads, and usage patterns.
- Compare solutions on total cost of ownership. Initial capital cost is only part of the picture — energy use, maintenance, and compliance all matter.
- Plan installation for the shoulder season. April and May are the sweet spot. Installations during peak summer cost more and disrupt operations.
