Cold Chain On The Brink As Fuel Costs Surge, Warns CoolKit Chief

The UK’s temperature-controlled supply chains are facing mounting pressure as a sharp escalation in fuel costs threatens the viability of transporting perishable goods, medicines and other essential products. In a timely and hard-hitting analysis for Van Fleet World, Rupert Gatty, Chief Executive of CoolKit, sets out the growing risks facing the cold chain, drawing on his extensive experience at the forefront of refrigerated transport and last-mile delivery.

Gatty highlights how rapidly rising diesel prices—driven by geopolitical instability and compounded by domestic policy pressures—are placing unprecedented strain on operators already working within tight margins. For cold chain logistics, the impact is particularly acute. Refrigeration units are energy-intensive by nature, meaning operators are not only grappling with higher fuel costs for transport, but also significantly increased expenditure to maintain consistent temperature control throughout the journey.

This dual cost burden is intensifying pressure across the supply chain, with fresh produce logistics especially exposed. For an industry that relies on speed, precision and reliability to maintain product quality and shelf life, any disruption or cost escalation risks rippling quickly from supplier to retailer—and ultimately to the consumer. Gatty warns that without meaningful intervention, operators may be forced to make difficult commercial decisions that could affect service levels, delivery frequency and pricing structures.

The analysis also points to longer-term structural challenges. While the transition to alternative fuels and electrified fleets is widely recognised as essential, progress remains uneven. Infrastructure limitations, high upfront investment costs and operational constraints continue to slow adoption, leaving many operators heavily reliant on diesel in the near term.

As the sector navigates these overlapping pressures, Gatty’s message is clear: the resilience of the UK’s cold chain cannot be taken for granted. Without targeted support and a more coordinated approach to managing fuel costs and energy transition, there is a growing risk that the stability of critical supply networks—including those underpinning fresh produce—could be compromised.
