• • • TRAINING• • • The Role of Heat Networks
in the UK’s Path to Net Zero As the UK accelerates its efforts to meet ambitious climate targets, the transition to low-carbon solutions across all sectors has become a national priority
emissions. To address this, heat networks are emerging as a leading solution in reducing emissions from buildings. With the government committed to phasing out fossil fuels, heat networks are being positioned as central to achieving net zero by 2050.
O
Heat networks work by distributing heat generated from renewable or low-carbon sources, such as geothermal energy, heat pumps or waste heat from industrial processes, through a system of insulated pipes. This heat is delivered to multiple buildings or homes, offering a more efficient alternative to individual gas boilers and electric heating systems. These networks can also utilise central sources of heat more flexibly, allowing for a range of energy-efficient options.
Industry Trends and Regulatory Shifts
The UK’s strategy to reduce carbon emissions involves a rapid increase in the use of heat
ne of the key areas in this decarbonisation drive is the heating sector, which accounts for a significant portion of the UK’s carbon
networks. The government has introduced a series of policy changes and funding opportunities to stimulate their development. The Heat Networks Investment Project has provided over £320 million in funding to kickstart the growth of these networks. This is complemented by the Heat Network Zoning consultation, which aims to identify areas where heat networks would be the most efficient solution for heat delivery. Furthermore, regulatory frameworks are evolving to ensure that heat networks deliver on their potential to decarbonise heat effectively. The government will introduce the Heat Networks Technical Assurance Scheme (HNTAS) in 2025. This scheme will establish mandatory requirements, focusing on performance, reliability and sustainability. With HNTAS in place, the industry will see an increase in the oversight of heat network installations, which will need to adhere to higher standards across their entire lifecycle, from design and construction to operation and maintenance. HNTAS is expected to complement existing standards, such as the Heat Networks Code of Practice (CP1), developed by CIBSE in
collaboration with the Association for Decentralized Energy (ADE). CP1 already sets the benchmark for good practice in heat network design and management, but with HNTAS, it is anticipated that regulatory enforcement will add a layer of accountability and assurance to project outcomes.
Preparing Engineers for
Emerging Standards Given the increasing complexity of heat networks and the growing regulatory requirements, there is a pressing need to equip engineers with the necessary skills and knowledge to design, manage and operate these systems effectively. CIBSE has developed a two-day course focused on the Heat Networks Code of Practice (CP1). This course is designed to equip engineers with the practical knowledge and tools needed to deliver heat networks that meet the rigorous standards set out by CP1. Covering every stage of a heat network’s lifecycle, from feasibility studies to design, construction, commissioning and operation, the course provides comprehensive guidance on how to deliver effective, efficient systems.
The CP1 Code of Practice serves as a benchmark for good practice in the design and delivery of heat networks. It outlines key objectives and minimum requirements at each stage of a project, offering a structured approach to ensure that networks operate efficiently, minimise carbon emissions and meet user needs. By mastering these principles, engineers will be better positioned to meet current and future regulatory standards, including those mandated by the HNTAS once it comes into force.
One of the key advantages of the CP1 course is its focus on the practicalities of delivering heat networks. Participants learn how to assess different heat sources, design network layouts and optimise system performance to meet the specific demands of users. Additionally, the course covers vital topics such as network sizing, insulation, control systems and the integration of low-carbon technologies.
Grant Funding Available To support the professional development of engineers in this crucial area, CIBSE, with backing from the Department for Energy Security and Net Zero (DESNZ), is offering grant funding of up to £500 for the CP1 training course. This funding is available to professionals based in England, helping to reduce the cost of participating in this essential training.
