If you’re interested in delivering energy efficiency measures through the Energy Company Obligation (ECO), you should contact an obligated energy supplier.
If you’re already installing measures under the scheme and are looking for standardised templates such as the Declaration of Conformity and Completed Installation, AWG and Private Domestic Premises Checklist or the latest file naming conventions then visit the ECO reporting working group section of our website.
If you’re looking for the latest ECO2t guidance, including the Boiler Assessment Checklist, please visit our ECO2t guidance page.
What measures can be installed under ECO?
There are a wide range of energy efficiency measures that can be installed under ECO including insulation measures, heating measures and connections to district heating systems (new and upgrades). These include internal and external wall insulation systems.
You can find a list of measures in our ECO2 measures table. This provides information on eligible energy efficiency measures which suppliers can use to meet their ECO obligations.
The list of measures is non-exhaustive. Other measures may qualify, subject to review by us on a case-by-case basis.
What is ECO Brokerage?
ECO Brokerage allows ECO providers to sell ‘lots’ of ECO measures to energy companies in return for ECO subsidy. An anonymous auction is held every fortnight where these lots are sold.
The Crown Commercial Service hosts an online e-auction allowing energy companies to bid in real-time on each auction day.
For more information, and to access the service, visit the Department of Energy and Climate Change website.

The diagram below is part of the ECO Toolkit. We've developed it to help installers and other parties involved in delivering ECO measures to understand how energy efficiency measures are determined as eligible. The toolkit also contains links to useful resources and information.
