Transform-ER CIC: A New Model for Retrofit Delivery at Scale
8th June 2026
Jenny Danson
Transformer CIC, a community interest company set up to address systemic failures in the delivery of domestic retrofit at scale. The presentation was given by two of the four founding directors, covering the rationale for the model, how it works in practice, a pilot case study, and a discussion of why detail libraries and innovation alone cannot solve the problem without structural change.
The Problem Transformer Is Trying to Solve
The founding team has extensive collective experience across housing, design, software, and contracting, and came together specifically because repeated attempts to deliver retrofit at scale kept failing at the same points. Even where individual components of a project were well designed or innovative, the whole system broke down when it encountered traditional procurement, traditional contracts, or traditional liability structures. The innovation would start to deliver its promise, and then the commercial and contractual reality of a standard construction project would pull it off course.
The presenter drew a parallel with research into major infrastructure projects in London, where studies identified around 50% value leakage between the client and the delivery partners on the ground, created by the layered inefficiencies, risk pricing, and adversarial incentives built into conventional project structures. Transformer is designed to eliminate that leakage.
What Transformer Is
Transformer is a community interest company and system integrator. It is not a contractor, a manufacturer, or a developer. Its role is to bring together the right parties in the right way, identify where existing failures in the system sit, and restructure the whole process of delivering a retrofit project so that those failures are designed out rather than worked around.
The four founding directors represent software, design, housing, and contracting respectively, which reflects the breadth of what the model attempts to integrate. The founding philosophy draws heavily on learning from Heathrow Terminal 5 and Project 13 in the infrastructure sector, both of which demonstrated what becomes possible when long-term collaborative alliance structures replace competitive tendering.
The model operates as a circular, continuously improving system rather than a linear supply chain. The intention is to bring in more organisations over time, share learning openly, and build volume, which is how the approach becomes capable of contributing to retrofit delivery at meaningful national scale.
The Core Components of the Model
Better Data and Archetype-Based Pipelines
A foundational problem in current retrofit delivery is poor data. EPCs are an unreliable starting point, and targeting retrofit solely on EPC ratings is fundamentally flawed. Transformer's hypothesis is that the right unit of organisation is the archetype: grouping homes by property type and identifying standardised solutions that are appropriate for each archetype. This is what enables scale.
The presenter cited a 2,500-home external insulation project in Nottingham, where 1,500 of the homes were in the private sector, as evidence that archetype-based delivery can dramatically reduce cost per home. Transformer builds on this by creating archetype pipelines that make the process of selecting and procuring a retrofit more predictable and more efficient.
A Standardised Parts Catalogue
Rather than starting each project from scratch, Transformer maintains a catalogue of pre-designed, pre-priced kits of parts. These are not generic detail libraries. They are solutions with liability attached, supported by an internal design panel, and ready to manufacture. Each kit is then adapted to the specific home through a conversation with the resident and the landlord, so the standardisation enables personalisation rather than replacing it.
The analogy used was buying a kitchen: a standardised product with choices built in, delivered at a known cost, rather than the current retrofit experience of iterative briefs, redrawn details, repeated costing, and cost uncertainty right up to the point of delivery.
Single-Point Procurement and Alliance Contracting
One of the most significant structural changes Transformer proposes is removing competitive tendering from the process entirely, after the initial procurement of Transformer itself. The landlord procures Transformer, and from that point forward, all suppliers and delivery partners are brought in through a collaborative alliance rather than being competitively tendered.
The rationale is straightforward. Competitive tendering forces suppliers to price risk in, to go in low and find the money back through variations, and to protect themselves contractually rather than solve problems collaboratively. The cost of just getting onto a framework can run to tens of thousands of pounds per bid, which means suppliers are immediately starting from an adversarial position. Removing that friction is, in the view of the Transformer team, the single biggest lever available for reducing cost and improving quality.
Alliance members are selected on the basis of behaviours as well as capability. The model draws on IP Initiatives' contracting approach, which includes independent facilitation to assess whether parties can genuinely work in a collaborative way before a contract is signed. For larger-scale projects, IP Initiatives also operates with shared project insurance, which means parties can acknowledge mistakes openly and solve them rather than hiding them to protect their PI position.
Resident-Centred Delivery
The model places significant emphasis on resident engagement and satisfaction, not just as a value in itself but as a practical lever for programme delivery. A small discretionary budget per home, potentially only a few hundred pounds, allows the team to fix the things that matter to the resident: a storage problem, a water pressure issue, a blocked drain. The result is that residents are willing participants rather than obstacles, which means access is maintained, programmes keep moving, and the entire alliance benefits.
The Pilot Project
Transformer ran a pilot on a single home, but it demonstrated the model's potential in a concrete way. The house had previously been part of a programme in Barking and Dagenham where an offsite-manufactured solution had been trialled on 10 homes, taking over a year to deliver because of fit-out problems on site.
For the Transformer pilot, the alliance team, including the manufacturer, the designer, and the mechanical and electrical contractor, worked through all of those problems before anyone went to site. The delivery was structured around a three-day initial visit to prepare the property, remove services from walls, take an accurate scan for manufacturing, and install below-ground perimeter insulation. Manufacturing and design coordination then happened over a four-week period. The main installation followed.
The result was a fully insulated home with solar panels, battery storage, and a heat-pump-ready configuration, delivered in four weeks. The mechanical and electrical installation was contained almost entirely within the wall structure, so the resident experienced minimal disruption inside her home. Beyond the retrofit itself, the team fixed her vermin problem, repaired leaking drains, resolved a boiler pressure issue by fitting a water cylinder in the loft, and provided loft storage and a new hatch. She made food for the site team throughout. The project was delivered at half the cost of the previous programme.
Why Detail Libraries Are Not Enough
The second part of the presentation addressed a common assumption: that a good library of retrofit design details is the primary missing ingredient. The presenter, a director with a background in architecture and specification, argued that detail libraries are valuable but that they cannot deliver their promise on their own, for structural reasons.
Libraries cannot cover every situation. In retrofit especially, perhaps 10 to 20% of details from any catalogue will need adapting for each specific project, and once adaptation begins, liability becomes unclear.
There is no feedback loop. Architects rarely ring a detail library provider to report a site problem with a specific junction. Libraries improve on a desktop basis, not from real installation learning.
Liability stickiness causes duplicated work. Each party in a traditionally structured project has to re-examine and re-justify decisions made by the party before them, because they cannot afford to rely on someone else's liability position.
Commercial pressure causes drift back to business as usual. Even the best-intentioned project team will revert to conventional practice when a conventional contract is sitting over the top of an innovative delivery approach.
Innovative products rarely capture their efficiency savings on first delivery. If a contractor has not installed something before, they will not price for the time saving, and the client will conclude the product did not deliver on its promise, making them less likely to use it again.
The solution Transformer proposes is vertical integration of the ecosystem. Not forcing everything into a single black box, but operating as a new operating system within which all of the normal project parties can work more efficiently together. Pre-designed solutions with liability attached, alliance contracting that incentivises problem-solving rather than blame-shifting, and a continuous feedback loop that allows the catalogue to improve based on real site experience.
Procurement and Commercial Model
At present, Transformer can be procured as a prototype, which is a legitimate route given that it represents a genuinely different model. The ambition is to move toward single-supplier framework status as the project portfolio grows. The value of a framework would be that other landlords seeing homes being delivered that match their own stock could join the alliance and bring their pipelines into the same ecosystem, rather than starting a new procurement from scratch.
The alliance contract has been developed in two versions: a lighter version for smaller projects and a more sophisticated version adapted from IP Initiatives for larger-scale delivery. Both place the client inside the alliance rather than outside it. There is also an option for Transformer to contract directly with the client having third-party rights through to the delivery alliance.
The scope of the catalogue is not limited to external wall insulation. It includes external and internal insulation, solar, battery, heat pump, and Transformer is actively developing new products where gaps are identified, including an external heat pump module designed for properties where residents cannot afford to lose internal space, being developed initially for Barking and Dagenham.
