Schools maintained by both Swindon Borough Council and Wiltshire Council are not affected by the concerns that they could collapse, it is understood.

On Thursday it was announced up to 100 schools across England may have to close parts of their buildings because of the imminent concern of the collapse of buildings using a special lightweight type of concrete.

Reinforced autoclaved aerated concrete was used to construct schools, and colleges between the 1950s and 1970s in the UK but has since been found to be at risk of collapse.

In total, the government said 156 schools were found to contain RAAC, of which 104 require urgent action while 52 have already received repair work.

It is understood that schools under the control of either Swindon Borough Council or Wiltshire Council are not on that list.

a spokesman for Swindon Borough Council said: "We are working with the Department for Education but, to date, there is no indication that Reinforced Autoclaved Aerated Concrete (RAAC) has been used in the construction of any schools in Swindon.

"However, we will be carrying out further inspections over the next few weeks as a precaution.”

The government has faced criticism for not publishing the list of schools it has ordered to be closed. So far six schools have been named, none in the south of England.

Academy schools, free schools and voluntary aided schools run by churches will be informed directly by the Department for Education.

Further schools could be told they need to shut classrooms because they are fitted with a concrete that could suddenly collapse, the schools minister has admitted.

Mr Gibb insisted that the Government will pay for the costs of temporary accommodation after official guidance suggested schools will have to cover the emergency measures.

The Department for Education (DfE) has told 104 schools and colleges to partially or fully close buildings just as pupils prepared to return after the summer holidays.

But Mr Gibb conceded that more schools could be told to make closures as evidence-gathering continues over the presence of reinforced autoclaved aerated concrete (Raac).

“There may be more after that as these questionnaires continue to be surveyed and we continue to do more surveying work,” he told GB News.

But Mr Gibb insisted that pupils and parents should not be apprehensive about the risk during the wait for the results.

“No, they shouldn’t worry,” he said.

“That’s a very cautious approach, so parents can be confident that if they’ve not been contacted by their school it is safe to send children back into school.”

He insisted “we took the decision as soon as the evidence emerged” as ministers faced anger for only telling schools of the closures days before children start the autumn term.

Mr Gibb said “over the summer” they discovered a number of instances where Raac that had been considered to be low risk “actually turned out to be unsafe”.
