Gloucestershire’s hospitals have faced unprecedented challenges during recent heatwaves, with emergency departments experiencing their busiest days ever and critical medical equipment failing due to extreme temperatures and humidity.
Hospital leaders revealed that the last three heatwaves since early May have severely impacted diagnostic systems. During a heatwave in late June, only one MRI scanner was operational between Gloucestershire Royal and Cheltenham General hospitals, as reported at a health overview and scrutiny meeting on July 14.
Kevin McNamara, Chief Executive of Gloucestershire Hospitals NHS Foundation Trust, explained that climate change and rising temperatures are forcing major shifts in how seasonal preparations are managed across the health service.

“The heatwaves have not only pushed temperatures beyond the tolerance of some equipment but also humidity levels that rendered diagnostic devices inoperable,” McNamara said. “These conditions led to breakdowns, requiring immediate repairs and prioritization of emergency cases.”
He further highlighted that even hospitals with newer facilities faced similar equipment failures. Gloucestershire’s aging infrastructure—with fragile estates, malfunctioning air handling units, and leaking roofs—compounds the difficulties, often forcing the closure of rooms and delaying care.
This has resulted in a constant balancing act to minimize risks and prioritize urgent diagnostics, inevitably extending waiting times for other patients. McNamara emphasized that the impact from heat-related pressures has exceeded traditional winter strains on hospital services.
He urged that future summer healthcare planning must begin much earlier in the year to cope with these new demands. “We’ve seen record-breaking emergency department activity during the heatwaves, surpassing usual winter peaks. This marks a shift in healthcare dynamics that we must accommodate going forward.”
Similarly, the South Western Ambulance Service has raised concerns about resource strains due to the heat, adopting “summer planning” strategies akin to those used during winter surges to manage increased incidents.
As climate change continues to alter weather patterns, Gloucestershire’s healthcare providers face pressing challenges in safeguarding patients while adapting infrastructure and services to extreme heat conditions.
