Cowes Enterprise College on Isle of Wight hit with £9m repair bill
Parents have reacted angrily to news a £32m new school building is already facing an estimated £9m repair bill.
Cowes Enterprise College on the Isle of Wight opened in September but is suffering from a leaking roof and "electrical defects".
Isle of Wight Council has to meet the bill because contractors Pihl UK went into administration.
Parents of pupils at the school have described it as "unbelievable" and "a mess".
The BBC has been unable to contact Pihl UK for a comment.
The school project was commissioned by the Conservative-run administration at the council which was voted out last year.
Conservative councillor Chris Whitehouse said: "There's no getting away from it; we are going to have to spend vast amounts of money to make this college safe and fit for purpose."
The new building was planned eight years ago but building delays and bad weather caused it to open a year late in September last year - the same month the contractors went into administration.
The current Independent-run administration has warned the repairs could mean "less money for other things and more savings".
The authority said it was "undeniable" that the overall project had not delivered on time, quality or cost.
A recent council report said "the overall project management arrangements were fragmented" and the main contractor had "little experience of the type of school build involved".
