ECO3 Scoring Tool

Calculate the lifetime scores and total funding for ECO3 measures

Use our free Scoring Tool to calculate ‘lifetime scores’ and ‘total ECO funding’ for your ECO3 measures. The Scoring Tool is developed using the latest ECO3 Deemed Scores Matrix published by Ofgem. We’ve included the treatable area, applicable uplifts, and the Tool automatically applies proxies for heating systems.

The Tool is interactive and easy to use. Basic knowledge of ECO rules would be sufficient to use the Scoring Tool. Users can calculate scores for up to four measures in one session and can also download the scores in csv format.

For best user experience, please open the Scoring Tool on a desktop or laptop using any browser. This Tool uses Google Analytics to help analyse how the site is being used.
