To ask the Secretary of State for Health and Social Care, what recent assessment his Department has made of levels of prevalence of Reinforced Autoclaved Aerated Concrete (RAAC) in the NHS estate.

The National Health Service in England has been surveying sites and undertaking Reinforced Autoclaved Aerated Concrete (RAAC) mitigation work since 2019. Once the presence of RAAC is confirmed at a hospital site, it joins NHS England’s national RAAC programme, which is backed by £954 million. This programme has delivered mitigation, safety, and eradication works across all NHS sites in England with confirmed RAAC, to keep facilities safe and open and, over time, remove RAAC fully from the NHS estate. The Department has published a full list of hospitals with confirmed RAAC, which will be updated periodically and is available at the following link:

As of 29 February 2024, there were 54 NHS hospital sites with confirmed RAAC, and RAAC had been eradicated at four sites. Further eradication work has taken place since this date.
