Reinforced autoclaved aerated concrete (RAAC) is a reinforced version of autoclaved aerated concrete.

RAAC has been shown to have limited structural reinforcement bar (rebar) integrity in 40 to 50 year-old RAAC roof panels, which began to be observed in the 1990s.[1]

Children at risk

ITV News found 68 schools have RAAC and 1,466 haven't been checked

On 16 March 2023, ITV News reported:

Tens of thousands of children are being taught in schools built using concrete "liable to collapse" with "no warning". ITV News has found 68 schools have Reinforced Autoclaved Aerated Concrete (RAAC) – a potentially dangerous, lightweight, building material that was predominantly used in roofs between the 1960s and the 1980s.
The true number is likely to be higher, as our freedom of information request to 5,882 schools in England has revealed 1,466 schools built between the 1960s and the 1980s do not know whether they have RAAC, because they haven’t been checked.[2]

School closures

In August 2023 more than 100 school buildings in England were ordered to be closed while safety measures were installed after a beam collapsed at a school.

On 3 September 2023, Chancellor Jeremy Hunt said the UK government would "spend what it takes" to put right defective concrete in schools, but conceded that structural problems could be identified in more schools and other public buildings.

On 4 September 2023, and after confirming that more schools could be affected, Education Secretary Gillian Keegan was recorded on camera by ITV News criticising "others" for being "sat on their arses" while suggesting the UK government should be thanked for their response.[3]

Repair budgets cut

On the same day, Jonathan Slater, a former senior civil servant, claimed that British Prime Minister Rishi Sunak reduced the funds available for school repairs during his tenure as Chancellor of the Exchequer.[4]
