INTRODUCING THE NEW HNTAS REGULATIONS
The Heat Network Technical Assurance Scheme (HNTAS) came into force in January 2026 when Ofgem became the regulator for both communal and district heating networks - bringing them in line with the electricity and gas markets. Operators will now need to register their networks and have clear compliance plans and policies in place. For companies or individuals tasked with managing heat networks, this means preparing early: understanding your obligations, reviewing your documentation, and ensuring you’re ready to meet the new compliance standards.
IS YOUR HEAT NETWORK HNTAS COMPLIANT?
If you run a heat network, the clock is already ticking. The new regulations are clear and necessary, but for smaller and independent sites, getting up to speed is a real challenge. Larger developers have had teams planning for this. Many existing schemes haven't had that luxury.
That's where we come in.
D3 Heat Network Compliance is our dedicated service to help you understand what HNTAS means for your site, and what you need to do about it. No jargon, no overwhelm - just practical support tailored to you.
