The Final Countdown Pocket Guide to Ofgem Heat Network Compliance

Heat networks are now regulated.
That changes everything.

Ofgem regulation is here. The question now isn’t about what the regulations say – it’s whether the right processes, responsibilities and evidence are in place across every heat network you manage.

The Final Countdown Pocket Guide shows you what to prioritise now, where the biggest operational risks sit and the questions you should be asking of your teams and providers.

THE FINAL COUNTDOWN

January 2027 shouldn’t be your starting line.

The Authorisation Conditions are already in force. Compliance data is already being generated. And the January 2027 registration deadline is getting closer.

The biggest risk isn’t that nothing is happening. It’s assuming something is happening without knowing who’s responsible, how it’s being delivered or where the evidence sits.

The Final Countdown helps you focus on what matters most first.

Rather than treating every requirement as equally urgent, we’ve organised the guide around operational risk – helping you focus your time where it can have the greatest impact.

Know where you stand. Know what to do next.

This guide is designed to help you turn the requirements into practical action across the everyday operation of a heat network.

KNOW IT

Understand the requirement, risk and who is responsible.

BUILD IT

Make sure the right processes and controls are working in practice.

PROVE IT

Have the data, records and evidence to demonstrate it.

That directly reflects the framework established at the beginning of the Pocket Guide.

START WITH ONE HEAT NETWORK

Can you confidently answer these five questions?

01 — WHO IS THE HEAT SUPPLIER?

Who holds accountability for the supply activity?

02 — WHO IS THE HEAT NETWORK OPERATOR?

Who manages the plant, infrastructure and day-to-day network performance?

03 — WHO IS RESPONSIBLE FOR EACH CONSUMER REQUIREMENT?

Who delivers each requirement in practice?

04 — WHAT IS BEING DONE TO PROTECT RESIDENTS?

Are the right protections in place and working day to day?

05 — WHERE IS THE EVIDENCE?

Can you access the data and evidence the processes, actions and outcomes?

Can’t answer all five? That’s where your countdown starts.

HEAT NETWORK COMPLIANCE

Compliance happens every day.

Compliance isn’t a report you produce once a year. It’s the result of hundreds of things being done correctly and consistently across the everyday operation of a heat network.

YOUR CHOICE OF METERING & BILLING PARTNER MATTERS

Metering, billing, tariffs, vulnerability, complaints, resident support, reporting and evidence don’t operate in isolation. The more effectively they connect, the easier it becomes to manage compliance – and demonstrate it when required.

At Data Energy, we’ve mapped Ofgem’s regulatory outcomes against the policies, processes, controls, competencies, monitoring and evidence needed to deliver them in practice.

COMPLIANCE. BUILT IN.

Metering & Billing designed around the requirements of the regulated heat network market.
