This page contains general information for energy suppliers interested in the Energy Company Obligation (ECO) scheme. Detailed scheme guidance documents are included in the ‘Contacts, guidance and resources’ section of our website.
Energy suppliers have legal obligations under the Energy Company Obligation (ECO) scheme if they meet the obligation threshold. More information on this will be published soon.
When do suppliers become obligated?
At specific times we will ask suppliers to provide information on their customer numbers and supply volumes. This is used to determine whether a supplier is going to be obligated for the next phase of ECO, and, if applicable, the size of their obligations.
We offer advice and assistance to all newly obligated suppliers to make sure they’re prepared to take part in the scheme.
What are suppliers’ responsibilities?
Suppliers are responsible for meeting their obligations and ensuring that they, and any members of the supply chain acting on their behalf, comply with the scheme requirements.
How are suppliers’ targets worked out?
As scheme administrator, we’re responsible for setting suppliers’ obligations. We do this using a calculation based on their share of the gas and electricity supply market. This will be determined by the ECO4 legislation when is in force.
Obligated suppliers have the option to trade their obligations with other obligated energy suppliers. Our guidance page will describe how suppliers should go about trading their obligations.
The ECO register
Each month, obligated energy suppliers notify us of the measures they’ve delivered by uploading them to the ECO register. Measures can only be notified to the Register once the ECO4 legislation is in force. Contact us if you experience any problems using this, or require access.
Where do I find out more?
You can find more detailed information in the Contacts, guidance and resources section of our website.
