Sparks of 2026: No #11 Reonic - The installation software solution
Every retrofit company in Britain complains about the same thing. The work is not the issue. Demand is not the issue (usually). The bottleneck is the workflow. Endless forms. Fragmented data. Assessments that cannot talk to design tools. Installers who cannot see what assessors intended. Designers who cannot see what actually got installed. A chain of confusion running through every project.
Reonic is not a household name yet, but it is one of the most important software teams to watch in 2025.
Why Reonic matters
Reonic is building the glue that retrofit has been missing. Their platform aims to pull together the messy, unconnected parts of the retrofit process into one coordinated workflow. Instead of siloed tools for surveys, modelling, design, finance checks and installation evidence, they are pushing for a clean path from first visit to handover.
They are trying to solve three critical problems:
- Fragmentation. Every organisation uses different tools. Many are outdated. Some are incompatible. Reonic wants one workflow that can live across the entire supply chain.
- Evidence and assurance. Retrofit is in a crisis of trust. Installers need better guidance. Consumers need better protection. Funders need clear evidence. Reonic’s system is built around structured, verifiable data that can be checked and shared.
- Speed. Good companies waste hours stitching together reports, spreadsheets and photos. Reonic is working to remove that waste.
What makes them a contender for 2025
Reonic’s real advantage is not the software itself. It is their understanding of how retrofit businesses actually work. They have spent time with assessors, coordinators, installers and manufacturers. The platform is being shaped around real pain points rather than imagined ones.
A second advantage is their timing. The sector is about to enter a period where evidence, traceability and workflow discipline will carry far more weight. After the ECO4 revelations, every part of the supply chain will need to tighten up. Software built for this new era will have a major role to play.
Why some installers will love it and some will push back
Reonic’s approach is structured. It demands clarity, repeatable steps and better data. For progressive installers and coordinators, this will speed up delivery and reduce mistakes. For those who have relied on improvisation and loose process, it may feel restrictive. However the truth is Reonic's ability to soak up some of the 'soft side' of retrofit administration, put's it head and shoulders above it's immediate competitors.
The team at Reonic have developed (and are developing - it keeps improving) a tool that assists the parts of design and planning that produce the most friction - for both installers and consumers - there's a neat CRM function too.
The future of retrofit depends on making the process simpler, faster and more accountable. Reonic is one of the few companies aiming at that whole problem rather than a single fragment of it.
Why it earns its place in Sparks of 2025
Retrofit needs better tools. Better workflows. Better ways to handle the flood of jobs that will come once government finally gets serious about the Warm Homes Plan. The companies that solve workflow will shape the entire sector.
Reonic is trying to do exactly that.
