Heat Networks become a regulated utility in 2026

From January 2026, heat will be treated as a regulated utility.

If you manage a communal or district heating network, you’ll need to prepare for a number of changes that could impact how you run your network.

New regulations for Heat Networks are coming

From January 2026, Ofgem will become the regulator for both communal and district heating networks - bringing them in line with the electricity and gas markets. Under the new Heat Networks (Market Framework) Regulations 2025, operators will 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.

Complying with the new technical standards

As part of the regulatory changes, all communal and district heat networks will need to meet a new set of technical standards. The Heat Network Technical Assurance Scheme (HNTAS) will be used to assess networks against these standards.

While existing schemes will have a transition period, it’s essential that operators have compliance and improvement plans in place.

A key focus is an effective and compliant heat metering strategy - exemptions that previously applied under the Heat Network Metering and Billing Regulations will no longer be allowed under HNTAS.
