Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what recent assessment he has made of the extent of the use of reinforced autoclaved aerated concrete (RAAC) in (a) courts and (b) prisons.

The professional advice from experts on Reinforced Autoclaved Aerated Concrete (RAAC) has evolved over time, from advice in the 1990s that RAAC did not pose a safety hazard to more recent advice on identifying and assessing structural adequacy. The Government's approach throughout has been to follow the best technical advice. Departments have been surveying properties and depending on the assessment of the RAAC, decided to either continue to monitor the structure, reinforce it, or replace it. This is in line with the approach recommended by the Institution of Structural Engineers

In line with that expert driven approach, we have been working for several months to identify where we have the potential for RAAC to be present across the HMPPS estate. We are commissioning further surveys and assessments across a number of buildings to assess as soon as possible whether RAAC is present and what further action may be required. Mitigation and action plans from those assets containing RAAC will then be put in place.
