Details
These draft technical specifications for consumer connections detail the requirements and technical obligations to be fulfilled as part of the upcoming Heat Network Technical Assurance Scheme (HNTAS).
A consumer connection is the connection between a distribution network (either district or communal) and a single consumer heat system.
The specifications include the:
- technical requirements to be met
- performance monitoring requirements to be met
- key failures to be avoided
- evidence requirements to be provided to demonstrate conformity with HNTAS
They are for use by:
- heat network developers
- heat network designers
- heat network operators
- heat network equipment suppliers
- organisations within the heat network supply chain
These technical specifications correspond to the HNTAS: New build heat networks - draft assessment procedures for Consumer Connections.
Next steps
We will be requesting feedback on the information in these documents. We will run a change management process in parallel with the HNTAS technical standards consultation which closes on 15 April 2026.
We will make final versions of these documents available before the scheme starts.
