Ofgem publishes ECO3 District heating systems (DHS) factsheet and summary of proposal (SoP)

2 April 2019

On the 29 March 2019, Ofgem published their District Heating Systems factsheet and summar proposal as part of ECO3. 

This factsheet draws together the key areas of information for suppliers and the supply chain when engaging with Ofgem prior to delivering district heating (DHS) measures, and sets out the requirements for delivering these measures under ECO3. A summary of proposal (SoP) form is available in Appendix 1 which can be used to provide a brief summary of the project being completed.

It is not mandatory that suppliers contact Ofgem prior to a district heating system (DHS) project and as such we do not require suppliers to submit a DHS SoP as part of this. However, a SoP can be sent to us prior to the installation of a DHS measure should suppliers want clarification on the project. Please contact us on for any questions on DHS measures.
