Three tools, all free to use, all working from information you already hold. Heat Network Readiness Builder Five steps to establish where your networks stand and what still needs attention. Work through your networks, the organisations involved, the information you hold and the gaps, and finish with a picture of where you are rather than a score. Open the Readiness Builder /tools/heat-network-readiness-builder Ofgem Readiness Checklist Twelve items covering what Ofgem asks of operators and suppliers.

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.
