Retrofit has two parts, and the first one comes before any money is committed. Part one. Establish what the work actually involves. An investment decision needs more than a performance figure. It needs to know what would have to be done, what that involves on this particular network, what it is likely to cost and what it would be expected to deliver. That means investigating the physical system properly. Qualified partners survey what is installed and what condition it is in, establish what can be reused, develop the options and cost them against what each would achieve. Spinview holds the survey information, the technical findings, the options and the costs against the network they relate to, so the case put in front of a board traces back to the evidence behind it. This is also the stage where funding becomes relevant, because a costed and evidenced improvement is what a grant application needs. Could funding help? Part two. Deliver the work. Once the decision is made, qualified partners provide the engineering, design and delivery. Spinview provides the information, evidence, workflow, baseline, digital handover and performance tracking. The engineering judgement, design and delivery sit with the partner. Keeping the record after the works A retrofit creates a new version of the network. New assets are installed, drawings change, equipment is commissioned, manuals arrive and metering changes. The teams who carried out the work move on. The teams who operate the building inherit a folder. When that plant later develops a fault, the commissioning record is hard to find. Digital handover The updated drawings, photographs, asset information, commissioning records, manuals and post-works performance data go back into the same network record, connected to the assets and locations they describe. The operational team gets a usable record of what is there now. Move from the site to the space to the asset and see everything known about it. That also creates a clear line from the original problem, through the work carried out, to the performance achieved afterwards, which is what makes the investment demonstrable. Get in touch
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.
