Ofgem consults on heat-network authorisation arrangements

What Ofgem is consulting on

Ofgem opened a consultation on 5 October 2026 about interim authorisation application arrangements for new heat-network operators and suppliers. Responses close on 2 November 2026. The consultation also proposes changes to registration and nominated-operator conditions.

Its consultation document explains Ofgem’s decision to separate application arrangements from the developing Heat Network Technical Assurance Scheme (HNTAS), with an interim approach centred on consumer protection. The proposed application process remains under consultation.

Engin’s project commentary

For a contractor approaching commissioning or handover, this is a prompt to check how the future operator’s programme connects to the construction programme. Identify who will operate and supply the network, and who is tracking the relevant regulatory decisions and actions.

Alongside that work, agree the technical evidence and acceptance criteria for the M&E package: which design queries remain open, who witnesses the agreed tests, and who accepts the results? An application milestone should not be used as a substitute for resolving those engineering questions.

Keep a short interface schedule with an owner, required information and decision date for each outstanding item. Where an operator needs information from a designer, contractor or specialist, link that request to the relevant deliverable and programme milestone. Review unresolved dependencies before fixing handover dates.

A useful next project conversation

Bring the proposed operating arrangements, design scope and outstanding technical queries to the next coordination meeting. Engin can support the M&E design and construction interfaces; the responsible operator and its advisers should establish the regulatory steps applicable to the project.
