About the Energy Efficiency Calculator

The Energy Efficiency Calculator is an online tool that acts as a quick and simple way to work out how to reduce your energy bills. By entering a few details about your home the tool can give you some ideas about what you could do to improve it.

You can...

  • Enter as many or as few details about your home as you know - the more you enter, the more accurate the recommendations will be
  • See what improvements the tool recommends for you with details of costs, payback and work involved for each
  • Customise your plan by removing improvements you are not interested in and adding in additional ones you are

At the end of it, you can produce a report with the details of which improvements will work best for your home and the savings you could make. And you can save your details so that you can come back to your plan any time you want.
