More than 10 per cent of trusts and councils still haven’t responded to a vital government survey on “crumbly” reinforced autoclaved aerated concrete (RAAC).
Officials have been asking responsible bodies to complete questionnaires on the presence of the potentially dangerous material on their sites since last March.
But speaking in the House of Lords on Tuesday, academies minister Baroness Barran said: “Nearly 90 per cent of schools and responsible bodies have sent in their initial responses [to our questionnaire] and we are working closely with structural engineering sector to identify accurately both if the RAAC is present and if it poses a risk.
“We’re now running a small call centre within the department and there are, including sadly some local authorities, organisations we’ve had to contact multiple times. We’re working with MPs and others to make sure we get all the returns.”
