Heat networks study suggests regulatory uncertainty is slowing delivery

New research undertaken by Baxi has found that social housing providers and local authorities have good experience of heat networks, but regulatory uncertainty and stretched capacity are slowing delivery.

Heat networks are expected to meet 20% of UK heat demand by 2050, with an interim target of 7% by 2035, up from around 3% today. As local authorities and housing associations own and manage approximately two-thirds of all heat networks in the UK, these sectors will be central to that growth.

The manufacturer surveyed 100 housing associations and 102 local authorities and councils responsible for managing or operating heat networks this summer, alongside in-depth interviews with five housing associations, a heat network consultant and heat network contractor.

Interviewees consistently described organisational understanding as strong among a small number of lead individuals but considerably weaker across the wider organisation, suggesting sector confidence may rest on a narrower skills base than the survey alone implies.

Awareness of regulation is uneven. Metering and billing regulations were best recognised at 40%, followed by the Heat Network Technical Assurance Scheme (HNTAS) at 38%, while zoning trailed at 24%. Interviewees drew a clear distinction between knowing a regulation exists and understanding what it will require in practice and identified HNTAS as the policy most frequently disrupting forward planning.

Organisations are prioritising getting more from the assets they already have. Improving energy monitoring, heating controls and building management systems was the most common plan at 42%, ahead of developing or connecting new networks (40%) and upgrading existing ones (33%). Interviewees pointed to commercial viability, limited internal capital and uncertainty over future compliance standards as the main barriers to progress.

Funding awareness is reasonably high, though each sector is most familiar with the scheme built for its own circumstances – 61% of local authorities knew of the Green Heat Network Fund against 43% of housing associations, while 56% of housing associations knew of the Heat Network Efficiency Scheme (HNES) against 44% of local authorities. Interviewees were clear that access depends on more than procedural knowledge: match funding, technical evidence, internal capacity and budget cycles determine whether funding becomes a deliverable project.

Respondents also want more support from manufacturers. Alongside technical support during planning (29%) and operation (30%), around a quarter sought help with funding applications (26%), business cases (25%), regulatory compliance (25%) and staff training (25%). Interviewees asked manufacturers to move beyond equipment supply towards lifecycle partnership, including early design input, training, commissioning support, maintenance guidance and timely resolution of defects.

Responding to the report, Jeff House, director of external affairs and policy at Baxi, said: “It’s encouraging to see from our research that there is high confidence in heat networks amongst social housing providers, but we’d like to see the government remove the barriers slowing progress. Our ask is for government to provide a clear, phased route to compliance, protect and expand improvement funding, build recognised skills pathways, and ensure that additional costs do not fall unfairly on residents.”

The company has set out four policy recommendations for government to remove the barriers slowing progress:

  • Protect and expand HNES funding for optimisation studies, asset data and physical improvement works.
  • Provide a clear and phased HNTAS implementation roadmap, with realistic transitional periods for existing networks.
  • Create recognised heat network skills and competency pathways covering technical and regulatory functions.
  • Protect residents from unaffordable metering, billing and compliance costs, with tailored safeguards for vulnerable households.
