Campus-scale district networks can cross several buildings and organisations. Establish the physical network and the information available before setting priorities.
Relevant existing heat networks must be registered with Ofgem by January 2027. HNTAS is being developed and the final requirements, thresholds and timetable for existing networks have not yet been published.
Start with what you have, identify what is missing and keep the source of each record visible. Spinview connects property, network, regulatory, technical and performance information around the estate and assets it relates to.
Heat network regulation and technical standards continue to develop. We review our guidance against information published by Ofgem and the Department for Energy Security and Net Zero, and show the latest review date on regulatory and technical pages.
This website provides general information and practical tools. Requirements depend on the circumstances of each heat network, and this site is general information rather than legal, regulatory, financial or engineering advice. Where specialist advice is required it should be provided by an appropriately qualified adviser.
Spinview helps organisations collect, organise, review and maintain heat network information and evidence. RAG status shows information readiness within Spinview and is not a regulatory compliance determination. Regulatory responsibility, and the compliance determination itself, remains with the relevant operator or supplier.
