Labour have blasted Jeremy Hunt for failing to include any new money for schools riddled with crumbling RAAC concrete in his Autumn Statement.

Shadow Education Secretary Bridget Phillipson said: “It frankly beggars belief that as schools crumble around the next generation, the government made no new investment in schools capital at the Autumn Statement. Only Labour will deliver the high and rising standards our children deserve”

Meanwhile the list of buildings found to have been built with the cheap, bubbly concrete continues to grow, including more schools, public buildings and council homes. It was widely used in flat-rooved buildings constructed between 1950 and 1990.

It comes after intensive surveys found Reinforced Autoclaved Aerated Concrete (RAAC) in three schools in Stockport that had previously been given the all-clear. A council report shows of the three, Bramall High School, will have to spend more than £1.5 million on immediate work and installing mobile classrooms to keep children in face-to-face education after RAAC was found in the ceiling of around 30% of the school.

Some 17 classrooms including specialist technology and science labs were forced to close, as well as kitchens, toilets and staff spaces. Money for the temporary structures is coming out of local government budgets initially, and will eventually be refunded by the Department for Education (DfE). But the huge cost of fixing the rooves of schools across the country will come out of the already squeezed existing departmental budget, after Mr Hunt failed to allocate any more cash.

Elsewhere, Solihull’s Core theatre announced it would have to close until March after RAAC was found in the building. It joins theatres in Stockport, Dartford, Scarborough and Northampton in closing. And RAAC was found in 30 Aberdeen council homes, prompting the council to widen its inspections of housing stock.

Daniel Kebede, general secretary of the National Education Union said: “Schools have already seen years of under-investment, and in far too many cases school buildings have drifted into serious disrepair. The Chancellor couldn't even bring himself to fund urgent work on the school estate, following the RAAC scandal, which has brought such embarrassment to this Government.

"With underfunded and understaffed schools and colleges, and school buildings crumbling, the Government must prioritise investment in schools and colleges and fund a fair pay rise for staff next year.”
