Contacts, guidance and resources

This section of the site is primarily for those actively involved in delivering the Energy Company Obligation (ECO). This includes obligated energy suppliers, those in the ECO supply chain, and interested stakeholders.

The key documents and resources needed to successfully deliver measures under the scheme are collated on our ECO guidance page, and all recent ECO consultations and decisions located in our consultations and feedback page.

Our ECO public reports, updated on a monthly basis, show progress towards ECO obligations, and our forums and working groups page provides the latest updates and resources from forums such as the ECO reporting working Group, ECO suppliers’ Forum, and ECO stakeholder delivery group.

If you can’t find the information you’re looking for, get in touch with us at and we’ll be happy to help.
