Heat Network Technical Assurance Scheme Training Hub
The Energy Act 2023 provides the powers for government to mandate heat network technical standards across Great Britain through future regulation. The Department for Energy Security and Net Zero (DESNZ) is introducing regulatory technical requirements and the Heat Network Technical Assurance Scheme (HNTAS) to help Responsible Parties and heat network operators demonstrate compliance with these requirements.
HNTAS will be introduced in phases following consultation and finalisation of the policy proposals. This will give the sector sufficient time to understand the requirements and take the necessary steps to comply. The scheme aims to ensure that heat networks achieve minimum standards of performance and reliability. As DESNZ is still consulting on HNTAS, the information below may be subject to change as policy develops.
Disclaimer: The following training has been developed ahead of the Government's consultation on Heat Network Technical Standards. It is intended to provide background information on HNTAS and support understanding of the proposed scheme in its current form. As the consultation process progresses, elements of the scheme may change. Where required, updated training content will be made available to learners once the proposals have been finalised.
What Is The Heat Network Technical Assurance Scheme (HNTAS)?
The Heat Network Technical Assurance Scheme is a transformative new initiative to drive up technical standards across the growing heat network sector.
Developed by DESNZ, the scheme is designed to ensure heat networks are designed, delivered and operated to the highest possible standards, delivering better performance, greater energy efficiency and improved outcomes for end users.
At its core, HNTAS is about building trust and technical excellence in a critical area of the UK's net zero journey.
Whether you are a Designated Party, a Client commissioning a heat network project, or a Technical Professional looking to become a registered HNTAS Assessor, the scheme provides the knowledge, structure and tools needed to deliver and verify projects that meet the required standards.
How Will HNTAS Compliance Be Demonstrated?
Under HNTAS, heat networks will be required to pass assessments to demonstrate that they have achieved the mandated minimum technical standards.
Who Will Deliver The HNTAS Training?
Building Engineering Services Association (BESA), has been appointed by DESNZ as the HNTAS Shadow Training Provider.
Stakeholders have regularly raised the importance of setting up and delivering high quality training to prepare the market for regulation. DESNZ anticipate that HNTAS will introduce several new roles and create new job opportunities for the sector. BESA will develop and deliver training courses, many of which will need to be attended by organisations and individuals before they will be able to fulfil these roles.
Selected courses delivered will work towards achieving accreditation, which will ensure delegates receive high quality training and can perform key HNTAS roles to a high standard.
