ECO public reports and data

The charts below give an overview of energy companies’ progress towards their targets in the current Energy Company Obligation period (ECO3).

ECO3 commenced on 03 December 2018 and runs to 31 March 2022. Measures that meet the scheme rules can be delivered from 01 October 2018. Suppliers had to notify us of any measures installed between 01 October 2018 and 03 December 2018 by the end of February 2019. Any measures completed on or after 03 December 2018 must be notified by the end of the month following the month in which installation of a measure was completed.

We update the information in these charts on a monthly basis. We’ve included a breakdown of overall progress towards:

  • Home Heating Cost Reduction Obligation (HHCRO) 
  • Rural Sub-Obligation
  • Solid Wall Minimum Requirement (SWMR)

A supplier's compliance position is only indicative until we have made our final decision about whether suppliers have achieved their obligations at the end of ECO3.
