The charts below give an overview of energy companies’ progress towards their targets in the current Energy Company Obligation period (ECO2). This runs from 1 April 2015 to 30 September 2018. From 1 April 2017, energy companies' progress towards their targets includes ECO2t obligations.
These charts are interactive, allowing you to explore data most relevant to you. We update the information on a monthly basis.
We’ve included a breakdown of overall progress towards:
- the Carbon Emissions Reduction Obligation (CERO)
- Carbon Saving Community Obligation (CSCO including CSCO-Rural)
- Home Heating Cost Reduction Obligation (HHCRO)
- Provisional Solid Wall Minimum Requirement (PSWMR).
Some charts include approved ‘surplus measures’ that may be carried over from ECO1, which ran from 1 January 2013 to 31 March 2015. Surplus measures are treated in the same way as ECO2 measures and therefore can be re-elected to different obligations. As such, whilst the total volume of surplus measures will not change greatly, we expect the percentage attributed to each obligation will change in the future.
Additionally, 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. Three newly obligated suppliers (Economy Energy, Flow Energy and Spark Energy) are now included in the CERO, HHCRO, and PSWMR charts. Please note that as these charts cover approved measures to March 2017, and these new suppliers can only deliver measures from 1 April 2017, they will not have any measures attributed against their obligations and have no CSCO or CSCO rural obligation.

The table above shows cumulative measures approved by Ofgem under ECO2. It does not include surplus actions which may be carried over from ECO1 to ECO2.
#Boiler replacement measures have been separated into two measure types, 'Boiler Replacement' and 'Boiler Replacement Mains Gas'
*Room-in-Roof Insulation (RIRI) installations were previously listed under loft insulation measures, however they are now shown as a distinct measure category. This is to reflect that RIRI measures are more varied than loft insulation measures.
**where 'N/A' this measure category is not eligible to be claimed under this obligation.
***these are all heating control measures.
