Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what estimate she has made of the number of leasehold properties in England which contain Reinforced autoclaved aerated concrete.

The Ministry of Housing, Communities and Local Government does not gather data on the number of leasehold properties which contain Reinforced Autoclaved Aerated Concrete (RAAC). However, our current assessment is that prevalence of RAAC is low in housing.

All building owners should continue to manage building safety and performance risks of all kinds in their buildings, including RAAC, in a proportionate, risk-based, and evidence-based manner. To do so, they should continue to follow guidance published by the Institution of Structural Engineers (IStructE) to identify, assess, and manage issues relating to RAAC.
