Heat networks regulation: regular data reporting guidance

Overview

We are consulting on data reporting guidance for heat networks.

This consultation follows our authorisation and regulatory oversight consultation, published on 7 November 2024. We analysed the responses to this consultation published our decision on 8 August 2025.

We are now seeking views on this draft guidance to support heat network suppliers and operators to submit data to us. We will use this data to help us monitor their performance. The guidance provides:

• details of the data that must be reported to Ofgem
• the segments who must report data
• the reporting periods and timings for submission

We would like views from people with an interest in heat networks and particularly welcome responses from:  

• heat network operators
• heat network suppliers
• energy service companies
• housing providers
• consumer groups
• asset owners
• metering and billing agents
• trade associations

We would also welcome responses from other stakeholders and the public.
