HNTAS is Here: Why Metering & Monitoring Now Matter More Than Ever

Since 27th January 2026, heat network regulation in the UK has entered a new phase. OFGEM registration requirements are now in place, and the industry is moving toward a much higher standard of accountability, performance, and consumer protection.

For developers, building owners, and heat network operators, the message is simple: heat networks must now be able to prove they are operating efficiently, reliably, and fairly.

This is where the Heat Network Technical Assurance Scheme (HNTAS) (DRAFT) becomes a major focus.

At DMS Metering Solutions, we’ve spent the last 25 years supporting heat networks with metering and monitoring solutions. Now, as the regulatory landscape tightens, we’re helping operators and project teams align with the proposed requirements through accurate measurement, robust data collection, and practical technical support.

The Biggest Shift: Proof, Not Promises

Historically, heat networks have often been judged on design intent. But intent doesn’t always translate into real-world performance.

With the new regulatory framework now in place, heat networks are being pushed toward something far more measurable:

• Demonstrating efficiency through real data

• Identifying underperformance early

• Maintaining evidence for compliance and reporting

• Supporting accurate, transparent billing for residents

In short: performance must be proven, not assumed.

Why Metering & Monitoring are the Foundation of Compliance

Whether you’re operating a single communal system or a large district heat network, the ability to collect accurate, structured data is essential.

A strong metering and monitoring package allows you to:

• Track energy and water consumption accurately

• Understand system inputs and losses

• Spot inefficiencies before they become expensive issues

• Build confidence with residents and stakeholders

• Maintain clear documentation for assurance and audit purposes

If you can’t measure it, you can’t manage it - and you certainly can’t evidence compliance.

Where DMS Fits In

DMS supports heat networks with both the hardware and the expertise needed to build a compliant metering and monitoring strategy.

End-to-End Support

We can support projects from early-stage planning through to ongoing monitoring, including:

• Heat network surveys and technical input

• Meter selection, specification, and supply

• Plantroom metering for full system visibility

• Integration with Elvaco systems for data collection

• Ongoing access to data, review, and performance insight

• Support with documentation and compliance evidence

Our Metering & Monitoring Offering

Heat Metering

Accurate heat meters provide the core data needed for performance monitoring and fair billing. We supply heat meters suitable for a wide range of applications, including HIUs, risers, plantrooms, and district heating networks.

Water Metering

Water monitoring remains an important part of system oversight, particularly for multi-occupancy buildings. DMS supplies reliable water meters for both dwelling-level and communal applications.

Gas Metering (Plantroom)

Gas input measurement is key to understanding overall network efficiency. DMS supplies plantroom-suitable gas meters to support primary energy monitoring and reporting.

Electric Metering (Plantroom)

Electrical inputs - including pumps, controls, and plant equipment - are often overlooked. Electric metering helps complete the picture, enabling more accurate system performance analysis.

Integrated Metering Panels

Our integrated metering panels bring together heat, water, gas, and electric metering in a single, organised solution. This simplifies installation, improves data visibility, and makes it easier to report on performance and KPIs.

Why Choose DMS Metering Solutions?

• 25 years of UK metering experience across residential, commercial, and district heating

• Trusted manufacturer partnerships with Sontex, Apator PoWogaz, Elvaco, and Honeywell

• Future-ready solutions designed to support evolving heat network requirements
