In 2020, BEIS consulted on developing a regulatory market framework for heat networks to protect consumers, support market growth and develop low carbon networks. Within this consultation views were sought on introducing mandatory minimum technical standards for heat networks. This proposal received strong support from respondents, as did the proposal that heat network suppliers should demonstrate compliance with technical standards through a certification scheme. The full consultation and market response can be found here: https://www.gov.uk/government/consultations/heat-networks-building-a-market-framework A further heat networks technical standards consultation is planned for 2025, responses to which will need to be taken into consideration for the implementation of the scheme and the proposed requirements of the HNTAS Certification Body. The Energy Act (2023) provides for Ofgem to be appointed as regulator of the heat networks sector and grants Ofgem the power to authorise individuals to operate heat networks and undertake supply activity. Ofgem will grant authorisation to a heat network operator, provided that the operator’s network meets certain authorisation conditions. The Energy Act provides for compliance with minimum technical standards to be included as one of these conditions. This lays the foundation for technical standards secondary legislation which is expected to come into force in 2026 to introduce mandated minimum technical standards for heat networks (e.g. mandating requirements on water flow temperatures, pipe insulation, etc). The majority of heat networks (existing and new) across a range of different characteristics (large city sized district heating to single block communal networks) will be in scope of this requirement. To promote compliance with these minimum technical standards, we are developing an assurance scheme: HNTAS. The technical specifications which set out the minimum technical standards that heat network suppliers will need to adhere to, and that will be subject to assurance, is being written and is expected to be completed in 2025. Work is also underway to develop the assurance processes themselves, these being the procedures to assess compliance. Together, the technical specification and assurance processes represent normative documents, a set of documents describing what heat suppliers must do. Once legislation is in place, we intend to designate these normative documents as a Code, adherence to which will be required in regulation. Heat networks are comprised of several elements (e.g. energy centre, district distribution network, communal distribution network, thermal substation, consumer connection and consumer heat system). Heat networks also have several stages within the... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/hntas-certification-provider-ocds-h6vhtk-050059) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planning - **CPV codes:** 09323000, 09324000, 71631000, 71631300, 71730000, 79132000 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Contract Period:** 31/10/2025 to 30/10/2027 - **Renewal published:** yes ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F022650-2025) - **Last Source Update:** 2025-05-19T13:09:21.000Z - **This document generated:** 2026-10-27T05:49:53.263Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-050059
