Decisions that hold upin front of the board,the funder and the resident.
You plan places, not products.
Asset, sustainability and place teams plan the same homes from different spreadsheets.
For the people who answer for residents' running costs, the asset plan, the place and the carbon target. We build it with you.
Every team gets its own view of the same truth.
One maintained model of the place you answer for, home by home. One defensible base under all of them.
Your true position
Your stock is often in a better position than its records show. The model rebuilds each home from the records you already hold: surveys, completed works, grant-funded measures a stale certificate misses. So homes already at target are counted before new money is committed.
Evidence compounds
Kept current as evidence arrives, so the next scheme starts from the last one's proof, not another survey.
Surveys, installs and completed works feed the model as they happen. What a place learns compounds scheme after scheme instead of being bought again. The model sits beside the asset management system and the stock condition surveys you already run, drawing on what they hold rather than replacing them.
Provenance built in
Every number traces to the model that produced it, with what is known, what is assumed and where each input came from.
So when a number is challenged, the answer is already on the record.
The decisions a place turns on.
A place plan is four calls, made home by home. The model exists to make each one defensible, and the evidence behind them is shaped for the regimes boards already track, from Warm Homes and SHDF funding conditions to EPC C targets.
Homes as cheap for the resident to run as they can be made: every costed option carries the home's running cost, and the plan is judged on that before it is judged on carbon.
Which homes first
Priority across the place, set from evidence, in an order you can explain to the board and to residents.
What gets each one to target
Costed options per home, each with the logic that connects spend to outcome. Trade offs stay visible.
What it costs
Cost to target per home, and what it adds up to across the place. A total the board can interrogate line by line.
Whether it performed as promised
When a scheme completes, performance is read against the promise that justified the spend, on the same model. Evidence for the funder is assembled as the work happens, not reconstructed when the audit asks.
Every year the same stock answers the same questions: the year-end carbon number, the average SAP for the statistical return, the EPC C position. And every year the answers take months to assemble.
A promise is made every time a budget moves: this spend, this home, this outcome. The machinery below is what lets a place hold itself to it.
Below, that machinery at work: 24,924 London homes reconstructed from public EPC records, modelled through a full year before and after one conservative fabric package — loft top-ups and cavity wall fill, applied only where the public record honestly supports the measure. The median heat demand falls from 6,320 to 5,520 kWh a year, and the gain is anything but evenly spread: the first 10% of homes carry 65% of the gain. That concentration is the priority list a budget needs. Greater London is the demonstration cohort; the same modelling runs on any stock with an EPC record.
- homes, modelled before and after
- 24,924
- median heat demand, kWh a year
- 6,320 → 5,520
- of the gain sits in the first 10% of homes
- 65%
Homes beyond the 0–40,000 kWh window fold into the last bin: 1,531 before, 940 after.
32 homes model slightly worse after the package: homes where the smaller heat load sits badly with the fixed unit; the diagnostic names them. The curve crests just above 100% before settling back.
- Both calculation engines are cross-validated against output from government-approved SAP software.
- The same engines power a reconstruction of UK housing stock covering around 18 million dwellings.
- The Home Energy Model, run at 20 million home scale.
The two figures measure different things: 20 million homes is engine throughput, and 18 million dwellings is how much of the UK's roughly 30 million homes the stock reconstruction describes.
That reconstruction is the starting point for modelling your stock. For how programme evidence is kept as delivery happens, expected against observed for each home, see programme assurance.
The place model starts with a conversation, and the first piece of work is a scoped place diagnostic, producing exactly what the exhibit above shows, for your stock: one place, your homes, real numbers.
- A first conversation
Short and specific: your place, your homes and the decisions in front of them.
- A working session in the platform
A sample of your own stock, worked through in the platform against a decision you actually face.
- A first piece of work
The scoped place diagnostic, small and judged on its own result. The output is yours to keep.
What you keep
- A priority order across the stock.
- Cost to target per home.
- The evidence behind both, home by home.
- A record your board and funder can interrogate.
The outputs land in your systems and stay yours: every per-home result delivered into the estate you already run, priced per home, stated up front.
The first piece of work is defined and bounded; what follows is an annual licence covering the platform and its continuing improvement.
One place. Your homes. Real numbers.
Tell us where you would start, and we will scope the conversation around it.
