Heat Networks Operators Must Report Data Quarterly, Annually
Summary
Ofgem has published guidance requiring heat network operators and suppliers to submit data on both quarterly and annual bases starting Autumn 2026. The regulator will issue a Request for Information to all registered operators before the first reporting window opens, notifying them of their reporting obligations and providing access to the full list of required data points. This data reporting regime is designed to enable ongoing market supervision and protect customer interests.
What changed
Ofgem has issued guidance establishing new data reporting obligations for heat network operators and suppliers. From Autumn 2026, registered operators must submit data to Ofgem multiple times throughout the year on both quarterly and annual cycles. Before the first reporting window opens, Ofgem will issue a Request for Information to notify operators of their obligations and provide links to guidance containing the full list of required data points.
Heat network operators and suppliers should prepare to establish data collection and reporting systems to meet these upcoming obligations. Operators will receive reminders before each reporting window, and Ofgem has committed to publishing further guidance on the data reporting process before the first submission period begins. This reporting regime is part of Ofgem's broader compliance approach to supervise the heat network market and protect customer interests.

Introduction to data reporting
After successfully registering a heat network, operators and suppliers must regularly submit data to us. We'll need this data multiple times throughout the year, on both a quarterly and annual basis.
Data reporting is a key part of our work to protect the interests of customers and will enable us to supervise the heat network market on an ongoing basis.
Monitoring this data will support our approach to compliance, as well as improving our understanding of the sector. It will also help us identify areas for future policy work and inform any changes to our approach in the future.
Find out more about our heat networks compliance approach.
Responsibility and timeline for data reporting
From Autumn 2026, heat networks can submit data using our digital service. Before the first reporting window opens, we’ll issue a Request for Information (RFI) to all operators and suppliers of registered heat networks.
The RFI will:
- notify registered operators and suppliers of the obligation to report data to us
- contain a link to the guidance with the full list of data points We’ll also send reminders before each quarterly and annual reporting window.
Help with data reporting
To help heat network operators and suppliers understand the data reporting obligations, we've published guidance on regular data reporting.
This includes general guidance on our approach, information on the submission periods and a description of each data point.
We’ll publish further guidance about the data reporting process before the first reporting period.
