British classrooms have become out of bounds during winter because of broken heating systems, leaking roofs and faulty wiring.

British classrooms have become out of bounds during winter because of broken heating systems, leaking roofs and faulty wiring, according to building management company MITIE Group.

The company is urging local authorities to "adopt a more strategic approach" to building maintenance and "improve schools' infrastructure" for the year ahead.

It said: "Many of Britain's schools were built in the 1950s and use outmoded boilers and energy systems that are not only expensive and inefficient, but are now operating beyond their original life expectancy.

"Many break down each winter as schools turn up the thermostats or keep them working for longer in freezing conditions. Meanwhile, broken pipes and faulty electrics add to the problems schools face each winter."

According to the Local Government Association (LGA), £5 billion in capital investment is "essential" over the next 12 months "to ensure every child can be taught in a classroom which is safe and structurally sound".

However, there are concerns as to how such funds will be raised following the cancellation of the Building Schools for the Future programme in 2010.
