HNTAS Update 2026: What It Means for Heat Networks

The heat network landscape is changing, and it’s happening quickly. With new regulations coming into force and the Heat Network Technical Assurance Scheme (HNTAS) on the horizon, the focus is shifting across the industry.

It’s no longer just about designing systems that should perform well. The emphasis is now on demonstrating that they actually do.

A Shift Towards Accountability

For developers, consultants and operators, this marks a clear move towards greater accountability. Performance is no longer assumed at the design stage. Instead, it needs to be measured, verified, and, where necessary, improved over time.

This is where metering and monitoring come into sharper focus. Reliable data is becoming essential, not only for compliance but for understanding how systems are performing in real-world conditions.

Why Metering Matters More Than Ever

Accurate metering plays a key role in this shift. It provides the insight needed to:

• Track system efficiency

• Identify issues early

• Support fair and transparent billing

• Demonstrate compliance with evolving standards

Without this level of visibility, it becomes increasingly difficult to prove that a network is operating as intended.

Preparing for HNTAS

As HNTAS develops, the expectations around performance and reporting will continue to grow. Those involved in heat networks should be thinking now about how they collect and use data, and whether their current systems are fit for purpose.

Getting this right early will make it much easier to adapt as requirements become more defined.

Join us! 

Get ready to dive deep into the world of heat networks and HNTAS preparation at Heat Networks Live!

Heat network regulation is accelerating - and with HNTAS fast approaching, preparation

can’t wait.

If you are responsible for designing, delivering, managing or operating heat networks, this

event is for you. Join us for a full-day, in-person working session focused on what

HNTAS means in practice — not in theory — and how to get your projects, assets and

operations ready.

Hosted collaboratively by Data Energy, DMS Metering Solutions, Fairheat, Guru Systems, Intatec,

Isoplus and Vital Energi, this event brings together the organisations actively shaping,

designing, building, metering, monitoring and operating heat networks today.

Nexus - University of LeedsWoodhouse, England

Tuesday, May 5 from 8:30 am to 5 pm

Final Thoughts

The direction of travel is clear. Heat networks are moving towards a more transparent, performance-led future.

For the industry, this is a positive step. It encourages better outcomes for end users, stronger system performance, and greater confidence in heat networks as a whole.

If you’d like to discuss what these changes could mean for your projects, or how metering and monitoring can support compliance, feel free to get in touch with the DMS team.
