ECO4 Delivery Guidance

The ECO4 Delivery guidance and measures table are for suppliers and the supply chain. They provide guidance on the fourth Energy Company Obligation scheme, ECO4, including:

• how a supplier meets its obligations
• the eligibility of different homes and the households that occupy them
• the eligibility of different energy efficiency measures
• the measure and project notification processes
• measure and project scores
• technical and score monitoring
• auditing and counter-fraud processes

This guidance document has been updated to clarify the circumstances when we will seek to reject non-compliant measures, how to define rural areas in Scotland, and general formatting and drafting improvements. Further details of the updates contained in this version are provided in the separately published subsidiary document below.
