Watford Grammar School for Boys and Watford Grammar School for Girls are among several schools in the area to receive government funding to carry out improvements.
Improving fire safety, water main replacements and replacing windows are all on the to-do list for eight schools in the borough, the Watford Observer reports.
More than 1,000 schools across England will receive a share of £434mn from the government’s Condition Improvement Fund to help ensure they have well-maintained facilities.
Education Secretary Gavin Williamson has said that the government’s “number one focus” is to make sure that “every student has access to excellent education and training”.
He said: “Replacing and upgrading poor condition school and college buildings with modern, energy efficient designs will give our students and teachers the environment they deserve and support them to maximise their potential.
“As we look forward to this September and all children returning to school, we can be assured that for years to come this country’s education system will drive opportunity and prosperity for all.”
