About Data Energy
FOUR STEPS. ONE CLEAR PATH.Â
You’re Probably Already On the Right Track
The good news is that compliance isn’t about reinventing the wheel. If you’re managing communal heating, billing residents fairly and maintaining your plant rooms, you’re already most of the way there.
The next step is about tightening processes, documenting them clearly and working with trusted partners to fill any gaps.
At its core, compliance comes down to four simple actions:
Meter it. Bill it. Maintain it. Manage it. Sorted.
Do these well and you’re not just compliant – you’re protecting residents and your organisation.
THE HEAT IS ON
Regulations now LIVE
Ofgem’s heat network authorisation conditions, effective from 27 January 2026 under the Energy Act 2023, set clear regulatory obligations for operators in Great Britain – with a focus on consumer protection, fair pricing and financial resilience.
Key requirements include registration, notifying material changes and meeting defined supplier standards.
The direction is clear – now it’s about readiness.
Our Playbook helps you move from awareness to action, without panic, guesswork or last-minute fixes.

The 25 Authorisation Conditions:Â Explained
The Heat Network Market Framework Regulations (HNMFR) introduce 25 Authorisation Conditions that all heat network suppliers and operators must meet.
They set clear requirements for behaviour, transparency and governance. These are not optional best practice – they are conditions of authorisation.
We’ve created a practical summary that brings all 25 conditions together in one clear reference for operators and property managers – to help keep your buildings safe, compliant and future-ready.
