Free Building Energy Waste Checker

Could your building be wasting energy without anyone noticing?

Building Energy Waste Checker

Get an instant indication of whether hidden energy waste may be going unnoticed in your building.

Many buildings waste energy through operating hours, hidden night loads, poor schedules, controls and equipment running when it is not needed. The difficult part is that this waste is often invisible until someone looks at the data and operating patterns properly.

This free checker helps you understand whether there may be practical opportunities to investigate before committing to bigger projects, new technology or capital upgrades.

No generic retrofit checklist. The questions focus on how your building is actually operating: energy visibility, out-of-hours use, controls, schedules, major loads and how opportunities are managed.

Start with diagnosis

Before investing in new technology, find out whether the existing building is running properly.

Energy-saving conversations often jump immediately to solar panels, lighting upgrades, insulation, glazing or replacement plant. Those measures may have a place, but they are not always the first thing to check.

A building may already be wasting energy through overnight use, poor schedules, controls that no longer match occupancy, or major loads that no one is routinely reviewing. Finding those issues first can help make later investment decisions more practical and better targeted.

Choose the best version

Use the general checker below, or choose a more tailored sector version.

The general checker is suitable for most non-domestic buildings. If you manage one of the sectors below, the tailored checker may feel more relevant to your building, responsibilities and common challenges.

Workplaces

Workplace Energy Waste Checker

For organisations managing offices, headquarters and occupied business buildings where energy is one part of a much wider operational role.

Common challenges
  • Unexplained increases in energy use
  • BMS schedules that look correct
  • Out-of-hours consumption
  • Limited time to analyse energy data

For shops, showrooms, branches and customer-facing estates where site comparison, local performance and investment priorities all matter.

Common challenges
  • Some sites using far more energy than others
  • Estate data without time to investigate outliers
