Heat Network Regulation: Key Takeaways for Commercial Real Estate

The UK's heat network sector is undergoing its biggest regulatory change to date. During Trio's recent Leadership Roundtable, representatives from Ofgem, legal specialists, technology providers, property owners, and managing agents explored what these changes mean in practice and how organisations can prepare. While some technical requirements are still being finalised, several clear priorities emerged from the discussion.  

Heat network regulation is here, not coming 

One of the strongest messages from the session was that heat network regulation is no longer a future consideration. The regulatory framework came into force in January 2026, meaning organisations operating heat networks are already subject to regulatory obligations. Registration must be completed by January 2027, but compliance responsibilities apply now.  

From Ofgem's perspective, the aim of regulation is to improve consumer outcomes and build confidence in heat networks as an affordable, reliable, and low-carbon heating solution. Greater transparency, accountability, and consumer protection are expected to support long-term investment in the sector while helping deliver better outcomes for customers.  

For property owners, landlords, and managing agents, the key takeaway is simple: preparation should already be underway. 

Organisations need a clear understanding of their heat networks 

A recurring theme throughout the discussion was that many organisations are still identifying heat networks within their portfolios and determining who manages each stage of the process. 

The challenge is not simply identifying whether a heat network exists. Organisations also need to understand: 

• Who owns the network assets 
• Who operates the network 
• Who manages customer relationships and billing 
• What responsibilities sit with landlords, managing agents, suppliers, and third-party contractors 

Unlike many regulations that apply to a specific type of organisation, the new framework is based on activities and responsibilities. As a result, different parties may have different obligations depending on their role within the network.  

Before thinking about compliance, organisations need visibility across their portfolios and a clear understanding of how their heat networks are structured. 

Data, metering and monitoring will underpin compliance 

If there was one area that generated the most discussion, it was data.  

Future compliance requirements will rely heavily on accurate metering, monitoring, and reporting. Many existing heat networks were designed long before these requirements were envisaged, leaving organisations with significant work to do to understand current capabilities and identify gaps.  

While technical standards are still being finalised, the direction of travel is clear. Organisations will need robust data to support performance reporting, demonstrate compliance, and provide greater transparency to consumers.  

For many property owners and managing agents, the first step is not implementing new technology. It is understanding what exists today and where information gaps remain. 

Transparency around billing and cost recovery will come under greater scrutiny 

The introduction of regulation is expected to place much greater focus on how heat network costs are recovered and communicated.  

Participants discussed the importance of being able to clearly explain how charges are calculated, what costs are included, and how those costs are allocated across occupiers. In many cases, organisations may need to revisit historic charging methodologies and ensure they can evidence and justify existing arrangements.  

For commercial real estate organisations, transparency is likely to become just as important as compliance. Occupiers will expect greater visibility into how charges are determined, while landlords and their managing agents will need clear, documented processes to demonstrate fairness and consistency.  

Don't wait for every detail before taking action 

While much of the regulatory framework is established, several panellists acknowledged that some technical requirements and implementation timelines are still being finalised. This uncertainty can make it tempting to delay action. 

However, the overwhelming consensus from the roundtable was that organisations should focus on what they can control today.  

Practical actions that can be taken now include: 

• Identifying heat networks across portfolios 
• Clarifying ownership and responsibilities 
• Beginning the registration process 
• Auditing metering and monitoring capabilities 
• Reviewing recharge methodologies 
• Assessing governance and reporting arrangements 
• Engaging with advisers and regulators where clarification is needed 

By taking these steps now, organisations will be better positioned to respond as further guidance and technical standards emerge.
