The 29 Ofgem heat network authorisation conditions
Every authorised heat network in Great Britain is subject to these conditions. Which of them apply to you depends on whether you operate the network, supply heat over it, or both, and on whether any of your consumers are domestic.
Each condition below links to its full verbatim text alongside a plain-English explanation. If you are not yet sure which apply to you, the registration checker works that out in a few questions. Registration closes on 26 January 2027.
