Heat Network Registration January 2027 Deadline: Have You Identified Your Heat Networks Yet?

Managing multi-let buildings? Now is the time to review your heat networks.

If you own or manage a multi-let building with communal heating, cooling or hot water supplied through shared pipework, you need to understand your position and act now.

The introduction of the new Ofgem heat network regulatory framework represents a significant change for organisations connected with relevant heat networks. With the registration deadline approaching on 27 January 2027, landlords, building owners, asset managers and managing agents need to identify potentially affected buildings, understand what information is available and allow sufficient time to prepare for registration. We covered the background to this in our heat network regulations update.

The challenge for many organisations is not simply completing a registration process. The challenge is knowing:

• Which buildings within your portfolio may contain a relevant heat network
• Who is responsible for operating and supplying each heat network
• What information is available
• What information still needs to be gathered

What is a relevant heat network?

A relevant heat network is generally a system where heating, cooling or hot water is generated centrally and supplied to more than one customer through shared pipework. This can be a communal heat network, meaning one building with multiple tenants, or a district heat network serving multiple buildings.

Potentially affected buildings may include:

• Multi-tenant commercial office buildings
• Residential apartment blocks with communal heating or hot water
• Mixed-use developments
• Buildings with central heating, cooling or hot water systems serving multiple occupiers

The key consideration is not simply the building type or size. It is how the energy is generated and distributed to customers.

Why do you need to act now?

Many organisations manage large property portfolios, and identifying potentially affected buildings takes time. Before registration preparation can begin, you need to understand:

• Which buildings contain relevant heat networks
• What technical information exists
• Where missing information may be held
• Who the relevant responsible organisations are

Information may sit across multiple parties, including building owners or landlords, heat network operators, heat suppliers, maintenance contractors and metering and billing providers. Waiting until the deadline approaches may leave insufficient time to identify gaps and gather the information required.

Previous heat network assessments may not tell the full story

Many buildings were previously reviewed under the former Heat Network Regulations, which focused primarily on the feasibility and cost effectiveness of individual heat metering. The new Ofgem regulatory framework has a different focus. The priority is now understanding:

• The heat network itself
• The responsible organisations involved
• The information required to support registration
• The arrangements in place for heat network customers

This means buildings previously assessed under the former requirements may still require review under the new framework.

What should you do now?

1. Identify potentially affected buildings

Review your portfolio and identify buildings where multiple occupiers receive heating, cooling or hot water, energy is generated centrally, and energy is distributed through shared pipework.

2. Gather available information

Collect available information relating to:

• Building layouts and floor plans
• Heating, cooling and hot water systems
• Plant locations
• Metering arrangements
• Ownership and operational responsibilities

3. Understand your registration readiness

Once a building appears to contain a relevant heat network, the responsible organisation should confirm what information is required and prepare for registration.
