In order to identify and prioritise opportunities to reduce energy usage, we’ve devised this handy checklist to help you. In some cases, things can be rectified simply by communicating with employees and altering the way you usually do things. Others may require the repair or replacement of certain items, while brand new equipment might have to be installed.

Here are a few questions to ask about your Business.

  • Are any areas in the premises over or under heating?
