ECO public reports and data

The charts below give an overview of energy companies’ progress towards their targets in the previous Energy Company Obligation period (ECO2). This ran from 1 April 2015 to 30 September 2018. From 1 April 2017, the energy companies’ progress towards their targets includes ECO2t obligations. We update the information in these charts on a monthly basis.

We’ve included a breakdown of overall progress towards:

  • Carbon Emissions Reduction Obligation (CERO including CERO-Rural)
  • Home Heating Cost Reduction Obligation (HHCRO)
  • Home Heating Minimum Requirement (HHMR)
  • Provisional Solid Wall Minimum Requirement (PSWMR)

Economy Energy and Flow Energy have traded all of their obligations using the trading provision in Section 30A, therefore we have chosen not to show them in these charts. Spark Energy have ceased trading however they had previously traded all of their obligations so are not referenced in this report as well. Please note that as these new suppliers can only deliver measures from 1 April 2017, they do not have a CSCO or CSCO rural obligation. 

Extra Energy have ceased trading, however we will continue to outline their delivery position as of the point they ceased to trade. This is because the measures delivered are active in the obligation period to which this report refers.

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 ECO2.

As CSCO final determinations have now been made, we are no longer including CSCO or CSCO Rural data in our reporting going forward. Suppliers may re-elect excess CSCO measures to count towards their other obligations in the coming months.

ECO3 commenced on 3 December 2018 and runs to 31 March 2022. Measures that meet the scheme rules can be delivered from 1 October 2018. Suppliers must notify us of any measures installed between 1 October 2018 and 3 December 2018 by the end of February 2019. Any measures completed on or after 3 December 2018 must be notified by the end of the month following the month in which installation of a measure was completed. The first set of ECO3 charts will be published in February 2019.

This chart shows measures submitted to the end of November 2018 and approved by the end of December 2018 as a percentage of phases 1, 2 and 3 of ECO2.

All surplus actions from ECO1 to ECO2 have been approved and are included in the chart. Surplus actions, like ECO2 measures, can be re-elected to different obligations. Whilst the total of surplus actions will not change greatly, we expect the percentage attributed to each obligation will change in the future. Please note that measures that count towards PSWMR are from both ECO1 and ECO2. 

Phase 1 of ECO2 ran from 1 April 2015 to 31 March 2016.
Phase 2 of ECO2 ran from 1 April 2016 to 31 March 2017.
Phase 3 of ECO2 (ECO2t) ran from 1 April 2017 to 30 September 2018.

The chart shows energy companies’ cumulative monthly progress towards the overall ECO2 obligation based on approved measures only. 

All surplus actions from ECO1 to ECO2 have been approved and are included in the chart. Surplus actions, like ECO2 measures, can be re-elected to different obligations. Whilst the total of surplus actions will not change greatly, we expect the percentage attributed to each obligation will change in the future.

Please note, the chart is based on the notification period (the month after installation of the measure).
