ECO guidance and associated documents

Here you can access guidance and publications on the ECO scheme.

What our guidance does

It outlines:

  • how we determine which suppliers are obligated
  • how obligated suppliers can meet their obligations
  • when and what suppliers need to report on, and
  • information on ECO measures.

The ECO3 scheme commenced on 3 December 2018 and runs until 31 March 2022. The documents below apply to all measures installed on or after 1 October.

What it doesn’t do
