Two reports out this week will urge ministers to install sprinkler systems in classrooms to limit the growing scale of fire damage in schools, which looks set to rise above £100m this year.
The London Fire Brigade and the ABI are concerned about the increasing number of daytime fires lit by children. Few buildings have sprinkler systems, although insurers say they account for just 1.8% of the total cost of new buildings.
Today the ABI will launch "School Arson: education under threat" with figures suggesting that fires started during the school day are at record levels, accounting for a third of school blazes.
Today Zurich will tell council leaders that insurance premiums will have to rise because the firm is making a 100% loss on the business.
The number and scale of school blazes are rising, with the annual cost of replacing the buildings doubling to more than £96m since 1998.
