Helsby High School Electrical Installation
in Helsby, Cheshire
Electrical services for a new four-classroom block replacing outdated mobile classrooms at Helsby High School.

Project summary
Electrical services for Helsby High School
At Helsby High School, two outdated mobile classroom units were replaced by a new single-storey block containing four classrooms for up to 120 pupils. Working on the project with main contractor Pavaway, MARA Electrical delivered the £65,000 electrical services package. Its recorded scope included electrical distribution, lighting, small power, structured cabling, door access and an intruder alarm.
The brief
The project
Existing portacabins were demolished before the four-classroom extension was built in their place. The wider scheme took 30 weeks and was handed over in time for the start of the 2024 academic year. MARA’s role was the electrical services portion of that project; the supplied brief identifies Pavaway as the main contractor and Helsby High School as the end user.
