Dorchester Middle School is closed today as its heating system is being repaired.

The system broke down on Friday afternoon, meaning a new part had to be ordered.

In a letter written by the headteacher on the school's website, it says the part cannot be fitted until Monday and the whole system must be drained to complete the works.

It reads: "We are very sorry for the inconvenience this will cause but our top priority is the health and safety of our children, and not being able to provide heating in the classrooms, we have been left with no option but to close."

Parents were informed of the closure in advance by text and email.

The school is due to be open as normal on Tuesday morning.
