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 criteria 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.

Notes

  • Suppliers who have ceased trading and have not delivered any measures over the duration of ECO3 will be removed from this report. Similarly, suppliers who have traded their obligation to another supplier will also be removed from this report as they are not obligated to deliver.
  • Avro, Green Network Energy, Utility Point Limited, People's Energy, Pure Planet and Together Energy have ceased trading, however will remain on this report as they have delivered measures under ECO3. 
  • Hudson Energy and Shell merged and appear in this report under Shell Energy. SSE and OVO have merged and appear in this report under OVO Energy.

The table above shows cumulative measures approved by Ofgem under ECO3 to the end of May 2022. It does not include surplus actions which may be carried over from ECO2t to ECO3.

*cumulative totals do not always match month to month, this is because measures can move out of an approved status if they are included as part of our monitoring or measure change processes.

**these are all heating control measures including smart thermostats and TRV's.

***under floor insulation has been separated out from other insulation to highlight the high delivery under ECO3.

This chart shows the status for all ECO3 measures submitted to the end of April 2022. It does not include surplus actions from ECO2t.
