Publication date
Scheme name
For each ECO measure a supplier notifies to us, it must provide the associated ECO savings.
Calculating ECO savings
Generally, carbon and cost savings are produced by calculating the annual carbon saving in accordance with Standard Assessment Procedure (SAP) or Reduced data Standard Assessment Procedure (RdSAP) methodologies.
For measures not in SAP or RdSAP
Where SAP or RdSAP do not contain a methodology to calculate the savings for a particular measure, a supplier can apply for us to approve an appropriate methodology to calculate the savings.
The tables below detail appropriate methodologies we have approved. Other suppliers wishing to use an approved appropriate methodology should apply in writing to us at eco@ofgem.gov.uk.
