It comes as Winter Gardens Academy, in Hilton Road, issued a letter yesterday (August 31) saying Government policy on Reinforced autoclaved aerated concrete (RAAC) had changed and need to vacate parts of the school with “immediate effect”.

For Richard Kemp, he is annoyed by the short notice and feels “concerned” his children were in the school with the lightweight, bubbly form of concrete material, used between the mid-1950s and mid-1990s.

Speaking to ITV News, he said: “I’ve had a massive frustration that we’ve found out about this tonight – literally days before the children go to school.

“We want to ensure it’s safe, but the notice period seems ridiculously short.

“It’s really concerning that for five years, my children have been in the school that was – potentially – really dangerous.”

As a result, his six-year-old will attend a nearby secondary school.

According to the letter, it will take “six to seven weeks” for the works to be completed to bring buildings back up to safety standards.

The Echo has contacted the south Essex Academy Trust, who run Winter Gardens Academy, for a comment.

Kingsdown School, a special needs establishment in Eastwood, has also been subject to closure after its main building sparked concerns about RAAC.

In total, 156 schools are known to have RAAC – 52 of which have safety measures in place.

In June, Hockley Primary School, in Chevening Gardens, was forced to close due to its presence in ceilings, with pupils being moved to other Hockley schools Greensward Academy, in Greensward Lane or Plumberow Primary Academy, in Hamilton Gardens.

However, only early years and Year Three children will head back next month and use two unaffected classrooms, with others going to Westerings Primary Academy, in Sunny Road, and Plumberow Primary Academy.

Questions are now being raised about why the Government has now decided to shut schools after a warning five years after when Singlewell Primary School's, in Gravesend, Kent, roof collapsed without any warning.
