Heat networks with multiple operators

Summary

This chapter of the consultation document provides context for the section of the draft guidance that covers heat networks with multiple operators. 

Details

We outlined the advantages of being able to engage with a single party on regulatory matters related to the role of operator through:

We determined that requiring one operator to act as a single point contact is the most practical way of approaching regulatory engagement for heat networks with complex arrangements in the existing market.

We confirmed that where an operator is nominated as the single point of contact, they will not assume the regulatory responsibility of other operators but will be required to promptly share information and notifications between those operators and Ofgem. The other operators with deemed authorisation under the regulations will remain authorised persons and will need to comply with the general authorisation conditions from 27 January 2026.

The draft guidance explains these requirements that are set out in the Nominated operator authorisation condition.

The Nominated operator draft authorisation condition has been consulted on as part of Heat networks regulation: authorisation conditions for registration, nominated operator, and notification of changes and is included in the consultation, Heat networks regulation: authorisation conditions, with the full suite of authorisation conditions that will come into effect from 27 January 2027.
