Applies to England, Scotland and Wales

Documents

Details

These draft assessment procedures for heat network energy centres detail the activities to be undertaken to provide assurance that the obligations in the Heat Network Technical Assurance Scheme (HNTAS) Technical Specifications are fulfilled.  

An energy centre is a plant room that contains heat generation equipment and/or equipment connecting to an energy source.

The documents are for use by:

  • heat network assessors
  • heat network developers
  • heat network designers
  • heat network operators

These assessment procedures correspond to the HNTAS: New build heat networks - draft technical specifications for heat network energy centres.

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.
