How Watford Grammar School saved £5,641 by uncovering hidden energy waste
Energy monitoring revealed that 60% of the school's energy was being consumed when the building was empty. With clear data, they took action and cut costs immediately.
Rising energy bills with no clear explanation
Watford Grammar School for Boys is an academy in Hertfordshire serving 11 to 18-year-olds. The school's facilities team was concerned about consistently high energy bills but had no way to pinpoint exactly where the money was going.
Without granular data, it was impossible to understand whether the problem was inefficient equipment, poor scheduling, or something else entirely. They needed clarity before they could take action.
Data-driven insight through real-time monitoring
We installed our energy monitoring software, INSIGHTS, across the school's infrastructure. The platform generates clear, actionable reports showing exactly where and when energy is being consumed — broken down by time of day, building area, and system.
The data revealed a striking pattern: the majority of energy consumption was happening during nights, early mornings, and school holidays — times when the building should have been largely dormant.
The data showed that 60% of energy was being consumed at night and early morning, even when no one was in the building during holidays.
Clear data led to immediate, measurable savings
They are helping me provide ways of reducing our energy costs and Zoe was excellent in arranging the installation of two AMR devices, which will definitely help us in our goal to reduce our energy usage. The service they offer really does go above and beyond the norm.
