We develop heat projects. Others build and run them.
We work in three ways, and all three end with a de-risked, ready-to-build heat project. Specialist contractors do the building. A fund or heat network operator owns and runs the result.

Heat recovery retrofits
For data centre operators, and the planners who set conditions on them.
Most UK data centres throw their heat into the air through dry coolers and chillers. We design schemes that capture it from the cooling loops, usually at 30–45°C. Heat pumps then lift it to network temperature, and we route it to buildings nearby that need heat: offices, housing, leisure centres, hospitals, schools.
We design the scheme and manage delivery through specialist contractors. We don’t install anything ourselves, so neither of us carries contractor liability.
If your planning consent has a heat recovery condition, you can hand it to us. We find the buyer for the heat, design the connection, and take it to a scheme someone can fund.
Heat-ready new builds
For data centre engineering firms and developers.
We partner, not compete
You design the data centre. We join as the heat specialist, so your client gets a heat strategy without you building one in-house.
Useful temperatures
We make sure the cooling design gives off heat at temperatures a heat network can use, rather than trying to recover it after the fact.
Space and routes held open
We keep space for an energy centre and a pipe route before the site layout is fixed.
Planning story
A credible heat offtake plan helps your application through councils that are drawing up heat network zones.
Micro data centres
For owners of industrial sites, and buyers of sovereign compute.
Small sites of 2–5 MW on industrial units, close to heat demand. They run previous-generation GPUs, A100s and H100s, coming off hyperscaler contracts.
That hardware costs less and gets a second working life. It also uses more electricity for each unit of work than the newest chips, so it gives off more usable heat. That heat feeds the same heat network revenue as our retrofits, so it earns money instead of being a cost.
The compute is sold to UK buyers who need inference on sensitive data, under UK ownership.
Small first, then scale
We build a track record on simple projects before taking on whole districts.
Point-to-point first · 12–24 months
One data centre to one large heat user, such as a hospital, leisure centre or factory. Fewer parties, one heat contract, and a pipe you can draw on a single sheet.
District networks next · 3–5 years
Once point-to-point schemes are working, the same heat source can grow into a network serving housing, schools and offices.
Templates, run in parallel
Standard contracts, energy centre designs and site screening, so we can develop several projects across the UK at once rather than one at a time.
