Client Background

Midland Express Logistics Ltd operates a 120,000 sq ft ambient distribution centre on the outskirts of Birmingham, serving retail clients across the Midlands and North West. The facility runs three shifts, 5.5 days per week, with a fleet of 18 counterbalanced forklifts and 12 electric pallet trucks. Eight of the 16 loading bay doors had no barrier other than the roller shutter, which was opened at the start of each shift and closed at the end — leaving bays completely open to the external environment for 14–18 hours per day.

The Challenge

  • Energy cost: Gas heating bills had risen to £340,000/year. Analysis estimated 20–25% attributable to heat loss through open bay doors.
  • Pest pressure: Birds had become a persistent problem, entering through open bay doors. Pest control costs exceeded £8,000/year. Bird fouling on pallets had resulted in two customer complaints and one product rejection.
  • Temperature compliance: Confectionery and fresh produce clients required temperature documentation. Monitoring showed bay-adjacent storage areas frequently exceeding 18°C maximum during summer.
  • Staff comfort: Cold draught complaints from warehouse staff, particularly in north-elevation bays exposed to prevailing winter winds.
