Whole-system engineering,
end to end.
We work across the entire energy system — from the physics of a single wall to the strategy for a whole scheme. Four capabilities, one joined-up team, so nothing falls through the gaps between disciplines.
Building & retrofit
Healthier, warmer, cheaper-to-run buildings. We design out damp, mould, overheating and wasted energy with a fabric-first approach — high-performance construction, the right ventilation, and heat delivered efficiently.
Renewable energy systems
Renewable heat and power that fits the building and the grid. We design whole systems — generation, storage and controls — that earn their keep financially as well as environmentally, and play nicely with a decarbonising grid.
Modelling & due diligence
The numerical rigour that de-risks every decision before you commit. We model energy and cash flows in detail, then translate the physics into feasibility and finance that funders and boards can trust.
Research & development
Our R&D engine, run in partnership with Verto Homes. We prototype, monitor and prove the technologies and methods that make genuinely low-carbon building repeatable and scalable — not one-off heroics.
That work is delivered by Planet A Solutions CIC — our social enterprise, where community benefit is the purpose, not a side-line.
First principles. Real outcomes.
Understand
We measure what's really happening before proposing anything — your building, people and goals.
Model
We test options in detail so you can see cost, carbon and comfort before committing.
Deliver
We design and lead the technical work to completion — fabric, heat, power and controls as one system.
Prove
We measure results and share what we learn, so the next project goes further, faster.
