RAAC hospital clearance has reached seven more NHS sites in England, allowing the buildings to resume the medical tradition of keeping ceilings above patients.
Reinforced autoclaved aerated concrete was widely used in public buildings from the 1960s to the 1980s. It was lightweight, practical and apparently expected to remain dependable long after the people who installed it had retired, moved house and stopped answering planning queries.
The government says twelve more hospitals are on track to complete removals by the end of March 2026, backed by up to £440 million this financial year. The money will help hospitals remove concrete that spent decades being treated as infrastructure, despite increasingly behaving like an unresolved email with structural responsibilities.
The estates directorate has retired its previous estates strategy, which involved looking up occasionally and whispering, “Probably Thursday.” Officials now prefer a more modern approach: survey the roof, install temporary supports and describe the resulting corridor closures as a positive step.
“The concrete is resting comfortably in several skips,” said Dr Mortimer Slabworthy, Consultant in Acute Architecture. “Its condition is stable, unlike the timetable for replacing it.”
Hospitals with RAAC still in place have mitigations intended to keep buildings stable and safe while removal work continues. This means the NHS must care for patients, manage disruption and perform major construction projects in the same estate, rather like changing an engine during a motorway journey while insisting the passenger experience remains broadly unchanged.
For staff, progress means fewer buckets, fewer cordoned corridors and fewer opportunities to explain why a steel prop has joined the clinical team. For ministers, it means a photograph of an empty ceiling panel and the thrilling discovery that maintenance can become a national achievement if delayed for long enough.
The wider programme aims to remove RAAC from the NHS estate by 2035. The material has therefore mastered public administration: exceed your design life, avoid a firm deadline and remain embedded until removing you requires a funding announcement, a ministerial statement and several people in high visibility clothing laughing beside a skip.
At one cleared site, a waiting room magazine from 1987 was found to have aged better. Engineers immediately asked whether it could support outpatients, then realised it already had more resilience than the capital budget.
Seven hospitals have now lost their questionable ceiling material. Their walls celebrated quietly, because nobody wanted to test whether the building could carry a cheer. The official breakthrough is that the roof is no longer part of the clinical team. It has been promoted to infrastructure.
