  1. Updated the ‘Hospitals with RAAC in England’ list: 7 hospitals have eradicated RAAC since the last update (Kidderminster Hospital, Broomfield Hospital, Homerton University Hospital, Scunthorpe General, Churchill Hospital, Queen Victoria Hospital, New Cross Hospital). As RAAC was discovered in one hospital (Manchester University NHS Foundation Trust - Oxford Road), the overall total number of sites with RAAC has reduced from 48 to 41.

  2. Updated the 'Hospitals with RAAC in England' list: 9 hospital sites have eradicated RAAC since the last update (University Hospital Lewisham, Norwich Community, Barnsley, Chase Farm, Warrington General, Castle Hill, Blackpool Victoria, North Cambridgeshire - Wisbech, and Stepping Hill). Two additional hospital sites have confirmed newly identified RAAC (Queen Victoria Hospital in East Grinstead and Bristol Eye Hospital). The total number of sites with RAAC has reduced from 54 to 47.

  3. Updated the 'Hospitals with RAAC in England' list: 13 hospital sites have confirmed newly identified RAAC; 2 additional sites have eradicated RAAC; one site that previously reported RAAC eradication has recently identified additional RAAC.

Details

This page gives information on hospital sites in England that are confirmed to contain reinforced autoclaved aerated concrete (RAAC).

All hospital sites in England with confirmed RAAC are in NHS England’s ongoing national RAAC programme. This programme has been allocated over £1.3 billion since the 2021 to 2022 financial year so trusts can put in place the necessary remediation and failsafe measures alongside eradication.

The information on the spreadsheet includes:

  • site location

  • NHS trust

  • RAAC status

As of 10 September 2025, there are 41 hospital sites with confirmed RAAC in the rolling national programme, which has been in place since 2021. Since May 2023, 34 sites have been identified, following updated monitoring guidance from the Institution of Structural Engineers (IStructE).

Twenty sites have entirely eradicated previously confirmed instances of RAAC. Seven hospitals that are most affected by RAAC are also part of the New Hospital Programme for full replacement by 2030. Where possible RAAC is identified, visual inspections and structural surveys take place to verify its presence and level of risk. Once the presence of RAAC is confirmed, trusts join the national RAAC programme. This programme supports mitigation, remediation and wider planning to maintain safety.

Keeping hospital capacity open while carefully monitoring and mitigating RAAC until it can be removed is fully in line with current evidence and recommendations from IStructE.
