At least 17 Norfolk schools have been flooded during the Christmas holidays after freezing temperatures caused pipes to burst.

The county council's insurance department has so far received a total 19 claims from the schools which include Toftwood Infant School and Thomas Bullock Primary at Shipdham.

A spokesman said the problem was due to the 'prolonged sub-zero temperatures that we have been experiencing' and had affected 17 of the 434 schools the council was responsible for.

The headteacher of Toftwood Infant School, near Dereham, was called to the School Lane site by the holiday club who had discovered a leak in the roof outside the year one classrooms.

Joanna Pedlow, who lives nearby, said when she got there she found herself ankle-deep in water.

'I told them to put a bucket underneath and I would get there as soon as possible,' she said. 'They said they didn't think a bucket would hold it. When I got in, it was like a waterfall to be honest.'

A cold water pipe had burst and was flooding into a connecting corridor as well as running down the walls of the year-one classrooms.

Mrs Pedlow said: 'More worryingly, our ICT suite was also flooded from above and we suspect there is damage to a great deal of the ICT equipment.'

The school's nursery will be closed for the first week of the new term - re-opening on January 10 - to allow the 90 children in year one to use the room, along with the library and main hall, as a temporary classroom.

Staff, governors and parents have been told about the problem through the school's text-messaging service and the headteacher stressed that only the nursery would be closed when term begins on Wednesday.

Mrs Pedlow added: 'It could have been worse. If the holiday club had not been in, we might not have discovered it until we went back for a training day on Tuesday.'

A county council spokesman said: 'The risk and insurance department historically has always issued advice regarding preventative action to be taken over the Christmas holidays. This information was re-issued earlier in December.'

Teachers and children will return to their schools after a fortnight's holiday next week.
