Heat network regulations

Heat network regulations are changing. From metering to consumer protections, it’s important to know what’s coming, and what it means for you and your network.

Key regulations

Navigating heat network regulations doesn’t have to be confusing. From long-standing requirements to brand-new changes, here’s a quick introduction.

Heat Network (Metering & Billing) Regulations 2014

Since 2014, residents must be billed based on how much energy they actually use. That means installing heat meters at building and property entry points.

NEW: Heat Network Technical Assurance Scheme (HNTAS)

New rules are coming to make sure heat networks are built and operated properly. The goal? More efficient systems, fewer faults, and better services.

NEW: Ofgem’s Heat Network Consumer Protection Regulations

Ofgem has introduced new rules to make sure residents get fairer treatment, including clearer bills, better support, and access to independent help from organisations like Citizens Advice.

NEW: Heat network zoning

Zoning aims to identify areas where heat networks are the most cost-effective way to reduce carbon from heating. This gives local areas a head start in planning greener, cheaper heat.

Get ahead of the game

1. Register with ombudsman

Since 1st April 2025, all heat suppliers are required to register with the Energy Ombudsman, allowing for resident complaint escalation where things haven’t gone to plan.

2. Check your meters

Take stock of what’s installed, what’s working, and what’s not. Accurate metering is essential for billing, monitoring efficiency, and meeting existing regulations.

3. Get your efficiency checked

Do you know how your network is really performing? Compare actual efficiency to design intent and get recommendations for improvements before the new technical standards start.

4. Keep an ear to the ground

Some regulations are still in consultation or pilot stages, so staying informed is key. If you’re working with us, we’ll make sure you’re always up to date with the latest changes.
