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. The product is HeatAssure™, and we build the record with you.
The sector's records don't survive measurement.
Four facts every place plan now sits on.
The records are wrong, measurably
A study commissioned by Lloyds Banking Group of 121 social homes found 64% were more than a quarter away from what their EPC assumed, and identified almost £28,000 per property in savings from data-led targeting.
Delivery decides heat pump economics
The Electrification of Heat field trial puts the average heat pump installation at a seasonal performance factor of 2.8; the specialist-designed systems tracked by HeatPumpMonitor average 3.9. Parity with gas sits near 3.7. SPF is that performance measured over a real season; the certificate’s SCOP is its modelled counterpart. Same technology, different delivery.
The law now expects evidence per home
Awaab’s law sets legal timescales for social landlords to investigate and remedy damp and mould hazards. Answering for homes now takes evidence per home, not stock averages.
Funding now arrives with measurement attached
The Warm Homes: Social Housing Fund carries monitoring and evaluation duties, PAS 2035 builds measurement into retrofit itself, and EPC C commitments set the floor the whole stock is judged against. Reporting per home is part of the money now.
The measured study: Lloyds Banking Group with The Good Economy, 2026. The field data: the Carbon Trust for Innovate UK, 2026. Why certificates drift from the homes they describe: our analysis.
Every team gets its own view of the same truth.
One maintained record 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 record 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.
The record 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 its source, 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.
Product tools see one appliance in one home. This is the layer across every home you answer for.
Proof that installed systems perform as promised, boilers included, across the heating fleet you answer for. Verified from meter and connected data against the home’s governed record.
The decisions a place turns on.
A place plan is four calls, made home by home. The record exists to make each one defensible, with evidence shaped for the regimes boards already track: Warm Homes and Social Housing Decarbonisation Fund conditions, and EPC C targets.
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, commissioning is verified and seasonal performance is read against the promise that justified the spend, on the same record. Evidence for the funder is assembled as the work happens, by a party with no stake in the works, rather than reconstructed when the audit asks.
The fourth call has its own proof: performance read against the promise, home by home. Read the programme assurance proof.
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.
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.
Below: the 24,924 London homes (of the 24,931-home cohort) that carry through a full modelled year on both sides of one conservative fabric package, applied only where the public record honestly supports it. The gain is anything but evenly spread, and that concentration is the priority list a budget needs. 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 kWh saved comes from 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.
- The same validated calculations power a reconstruction of UK housing stock covering around 18 million dwellings.
That reconstruction is the starting point for modelling your stock. The working behind it, including how every calculation is validated, is on Technology.
This starts with a look, not a workshop: we build a working view of your place from public records first. The first piece of work is then a scoped place diagnostic, producing exactly what the exhibit above shows, for your stock.
- A first look, at no cost
Name the place and we build a working view of it from public records before we ever meet. Nothing needed from you to start.
- A working session in the platform
That view, walked through together against a decision you actually face, alongside a sample of your own stock.
- 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.
Data boundaries, IP and security, written for procurement: Trust.
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.
Your place, as the public record has it.
Name the place, and we will show you what the public record already says about it. Public records only: nothing from your systems, and no personal data. No cost to start, and a reply within two working days.
