As lead partner of Transform-ER, we've been helping transform the retrofit industry for speed, scale and quality
We led the Transform-ER (Transform. Engage. Retrofit) project, funded by Innovate UK, from 2023 to 2026. Building on the expertise of 13 industry leaders, it's now launched as a Community Interest Company that's offering a bold new integrated retrofit delivery model for social landlords and local authorities to achieve high-quality, cost-effective retrofit programmes at scale. Its first demonstrator project took a house from EPC D to A in four weeks - on time and on budget - using an innovative kit-of-parts full home solution - with a delighted resident.
Transform-ER is a hugely complex, multi-stakeholder innovation project that's achieving brilliant progress towards its mission of enabling retrofit at scale and speed. Energiesprong UK's leadership has been instrumental in shaping and supporting this terrific collaboration." Tom Bassett, Research Technical Lead at BRE
The consortium took a systemic approach to tackling the multiple, intertwined challenges in the sector, from spiralling costs and resident dropouts to delays and disappointing outcomes.
Using the Construction Innovation Hub’s Demand – Develop – Deploy structure, project partners focused on transforming retrofit from a fragmented 'cottage industry' into something genuinely scalable, structured, and repeatable with:
✓ Smart data and drone technology for aggregated property pipelines matched with proven, high-performance solutions – streamlining delivery while guaranteeing outcomes (led by Ambue and Planarific)
✓ Blended financing unlocking viable business cases that actually work, leveraging grant, HRA and private finance (led by Energiesprong UK)
✓ Collaborative alliancing for problem-solving partnerships that increase trust, reduce risk, drive certainty, and lower your costs (led by Energiesprong UK, KIN and Bow Tie Construction)
✓ Lower-cost, higher-quality, interoperable kits-of-parts solutions to offer better budget visibility, economies of scale and reduce time onsite (led by Bow Tie Construction, BRE, KIN , Ultraframe, Tata Steel and VundaHaus)
✓ Resident-first engagement so upgrades happen with people, not to them – delivering choice, agency, and trust while creating homes that residents love (led by Energiesprong UK)
✓ Independent oversight and an industry ‘retrofit rulebook’ provides honest learning, continuous improvement, and innovation (led by ESUK and the MTC).
As well as setting the tone for collaboration and embedding it throughout the project, Energiesprong UK contributed its expertise on procurement strategy, stock analysis, retrofit and contracting strategy, complex programme support and resident engagement.
