Heat networks regulation: registration guidance
Feedback updated 23 Jan 2026
We asked
We consulted on the draft registration guidance to support implementation of the heat networks regulatory framework. The guidance is designed to help authorised persons determine whether their activities are in scope, understand how to register, and clarify responsibilities in settings with multiple operators. The consultation sought stakeholder views on whether the draft guidance was clear and fit for purpose.
You said
We received 21 responses from a range of stakeholders including:
- operators
- suppliers
- housing associations
- consumer organisations
- trade bodies
- Ombudsman
- Energy consultant
Stakeholders broadly supported the draft guidance, valuing clarity on regulated roles and exemptions. Feedback called for clearer explanation of treatment of connected or embedded networks, a decision framework for determining ‘substantial control’ over heat network assets and included general requests for proportionality in the approach to regulation of small or self-supply heat networks. Stakeholders also requested more detail on registration processes, supplier and operator dependencies, vulnerability data handling, and practical examples for complex arrangements.
We did
We have made updates to the final registration guidance to address stakeholder feedback. The guidance will be strengthened by:
Adding examples further detail and examples for self-supply and industrial heat networks.
Setting out illustrative factors for determining ‘substantial control’ and providing worked examples for complex cases.
Confirming that registration will be managed through a digital service, clarifying service features and our intention to publish additional resources to support the service.
For networks with multiple operators, the guidance continues our non-prescriptive approach to avoid impacting established arrangements. It clarifies that nominated operators serve as the primary regulatory contact without assuming liability for others, with expectations applied proportionately on a case-by-case basis.

Overview
We are consulting on our draft guidance for heat networks registration.
This guidance supports authorised persons undertaking operation or supply on a relevant heat network during the first part of the initial period. It explains roles and responsibilities, registration requirements, and obligations under the Registration and Nominated Operator authorisation conditions.
It also includes specific guidance for registering Shared Ground Loop (SGL) heat networks and outlines what happens after registration is completed.
Who should respond
We would like views from people with an interest in heat networks and particularly welcome:
- heat network operators
- heat network suppliers
- energy service companies
- housing providers
- consumer groups
- asset owners
- metering and billing agents
- trade associations
Background
This follows our consultations:
- Heat networks regulation: authorisation and regulatory oversight which set out our policy on this topic
- Heat networks regulation: authorisation conditions for registration, nominated operator, and notification of changes, which covered the associated draft authorisation conditions
The draft guidance document is published alongside this consultation and should be considered in conjunction with our updated authorisation conditions included in the Heat networks regulation: authorisation conditions consultation.
Our aim is to support regulated entities to understand the scope of the regulatory
framework and their registration obligations.
