New Heat Network Technical Requirement Aims to Boost Performance and Accountability

Heating network

UK: A new regulatory technical requirement for heat networks is set to be introduced on 27 January, promising both practical and long-term benefits. The Heat Network Technical Assurance Scheme (HNTAS), expected in 2026, will ensure all heat networks meet consistent performance standards. Sophie Sibley, Principal Engineer at Synergie Environ, welcomes the development, noting that it will strengthen confidence in the quality of the UK’s heat networks. 

HNTAS builds on the voluntary CP1 (2020) standard from the Chartered Institution of Building Services Engineers (CIBSE). With Ofgem as the regulator, the scheme transitions from voluntary guidance to mandatory requirements across England, Scotland, and Wales. It addresses evidence of underperforming heat networks and is particularly critical as an estimated 50,000 new residential connections are expected each year, all of which must operate reliably. 

To achieve the UK’s 2050 net zero targets and maintain energy security, the shift to effective, dependable heat networks is essential. While CP1 provided a solid foundation, mandatory standards like HNTAS are needed to ensure best practices in monitoring, design, and operation are widely adopted. 

At its core, HNTAS aims to increase transparency around heat network performance and enhance accountability among operators. Poorly designed or managed networks can lead to dissatisfaction and inefficiency, making rigorous standards vital. The scheme’s objectives include reducing carbon emissions and costs, improving affordability, enhancing customer experience, and strengthening data collection and reporting.
