ECO reporting working group

We want the information that obligated energy suppliers collect from the supply chain about Energy Company Obligation (ECO) measures to be as consistent as possible.

To encourage this, the ECO reporting working group has been developed to facilitate the production of standardised evidence documents for use in the ECO scheme. The ECO reporting working group comprises representatives from both obligated energy suppliers and industry, including installers, managing agents and software providers.

Together we have produced a series of documents which should help to streamline the ECO reporting process for the supply chain.

The following document should be used in relation to measures installed on or after 1 October 2018:

At the time of publication, the draft ECO Order is still subject to parliamentary process, however we expect you to use these documents from 1 October 2018 onwards.

The documents below relate to measures installed between 1 April 2017 and 30 September 2018 only:

The documents below relate to measures installed between 1 April 2015 and 31 March 2017 only:

Some of the key benefits are:

for new entrants to the market

Clarity on some of the key requirements set by Ofgem and/or obligated suppliers

for firms working with two or more obligated suppliers

A single set of reporting templates and one reporting process for most measures (subject to contractual arrangements)

for most firms

There should be a reduction in time spent scanning and renaming files.

All Ofgem requirements referred to on this page relate to the ECO guidance

Supplementary note

ECO places a legal obligation on larger energy companies to deliver energy efficiency measures. Ofgem provides guidance on how these measures should be delivered in order to comply with legislation. Suppliers are responsible for ensuring that they, and any members of the supply chain acting on their behalf, comply with the applicable requirements of the law.
