Details

Government supports the growth of the UK heat networks market as a crucial part of the UK’s heat decarbonisation journey. Providing accurate information on the market and signposting upcoming projects to investors is essential for developers and other partners within the heat networks supply chain.

These pipelines contain overviews of projects and upcoming procurements that are currently being supported by government. We provide the most up-to-date information available to us, but it represents a single point in time, typically a quarterly extract or consultant’s report (the year data is received is noted).

Attached documents:

  • the Project Pipeline shows a broad overview of government supported projects, brings together heat network investment opportunities in England and Wales. It includes one page summaries of each project that includes a project description and other data including forecast financial information
  • the Procurement Pipeline provides information about upcoming procurement opportunities on heat networks projects supported by government funding and projects by HeatNIC members
  • the Heat Networks Planning Database (HNPD) provides a picture of heat network deployment across the UK based on planning applications. It tracks the progress of projects through multiple stages including inception, planning, construction, operation and decommissioning. This interactive map of the HNPD data shows the geographical spread of heat network projects

Through publishing these documents, we aim to:

  • provide an overview of the pipeline of the heat networks projects across England and Wales
  • enable potential sources of finance to assess the scale of the sector
  • facilitate conversations
  • enable new finance to enter the sector

If you’re an investor or new entrant and would like further information or if you would like to provide feedback on how we could improve these documents, please contact us at heatnetworks@energysecurity.gov.uk using Heat Networks pipelines in the title.

For the Heat Networks Planning Database, if you have information about a heat network scheme not included in the database, spot any inaccuracies, or have any feedback, please let us know by email to HNPD.enquiries@energysecurity.gov.uk.
