Retrofit the right homes first. Prove what the money bought.
HeatAssure™ is the independent energy record of every home you answer for: what each one is, what it was promised, and what it delivers, kept current.
- Your whole stock in priority order, with the reason recorded for every home.
- The annual return to the regulator, the funder's report and the answer about one street, all from the same evidence.
- Problems seen on your own record first, before they arrive as complaints.
The first look is free: name a place and a working view comes back from public records, showing which homes come first and why, with nothing needed from your systems.
The people who ask about your homes.
Records age faster than homes do wherever you look: a survey speaks for the day it was filed, and a certificate can describe a home that has since changed. The people you answer to ask anyway.
- The regulatorEvery home physically assessed and kept current: the duty since April 2024. The median large housing association takes five years to reach three quarters of its stock.
- The OmbudsmanOver two fifths of last year's compensation was for failures in handling leaks, damp and mould.
- The hazard clockDamp and mould investigations already run on working-day timescales; cold and overheated homes are due to follow from November 2026, subject to Parliamentary approval.
- The boardSigns the return, owns the forecast, and answers for one street the same evening.
- The funderMoney arrives with property-level reporting attached, and the next bid rests on the last one's evidence.
- The residentAsks about their home, never your stock, and lives with what it costs to run.
Everyone above is asking a version of the same two questions: which homes come first, and what is true of this one home, today.
The figures are the regulator's and the Ombudsman's own. The measured gap between records and homes: Lloyds Banking Group with The Good Economy, 2026, and our analysis.
That may be you as a landlord or a council, or the organisation delivering for you: a utility or retrofit partner answering for homes across every tenure, including homes it does not supply. The record judges the programme's promises the same way, whoever holds them.
Both answers come from the same record.
The right homes first. 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. A gas-heated home you have never touched can still tell you what it would take to reach EPC C.
One conservative fabric package, priced through a full modelled year across 24,931 London homes, applied only where the public record supports it. The gain sits in a minority of homes, and that minority is the priority list.
- 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.
What the money bought, the day you are asked. 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. One record per home ends the assembly: the return and the answer about one street become the same evidence added up. Where the money is Warm Homes: Social Housing Fund Wave 3, going back is a condition of the grant: a resident questionnaire between one and twelve months after the install, and checks on at least one in ten completed works.
A problem you find on your own record is a repair you schedule; the same problem arriving in a complaint or a determination costs more and reads worse. The record shows problems early, and records when they first became visible.
Decisions that hold up in front of the board, the funder and the resident.
The resident is the test.
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.
What lands on each of your desks.
- Asset managementThe plan starts from each home as it stands, so spend lands where it moves a home closer to target, in an order you can show.
- Compliance and regulationYear-end stops being an assembly job: the return, the regulator's questions and the answer about one street draw on the same kept evidence.
- Development and sustainabilityWhat every scheme promised is written down before the work starts, and what it delivered is read against that afterwards, home by home.
- Finance and fundingThe reporting a funder attaches comes straight from the record, per home, accruing as the work lands rather than assembled after it.
Your systems and surveys stay. The record keeps them current.
One product that closes the gap between what your records say and what your homes deliver.
We call this HeatAssure.
It starts from the records you already hold, reads every home connected or not, and sits beside the systems you already run, never replacing your surveys. Kept current as evidence arrives, so the next scheme starts from the last one's proof, not another survey.
The heating already installed is read the same way. 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.
Whoever pays for the record cannot change what it says, and neither can whoever did the work.
Each home is read against what it was promised, never against an average for homes like it.
Whoever answers for the home pays for the record, and the resident never does.
All three are published in full on Trust, which sets out how whoever pays is kept away from the verdict: the question a funder's audit or an Ombudsman case is really asking.
You start with one place, not a platform programme.
- HeatAssure, in fullWhat the record holds for each home, who sees it, and who pays.
- A city, read wholeHow heat varies across a whole city, one home at a time.
- One estate, pricedWhen a retrofit pays on one social housing estate, home by home.
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.
- The same validated calculations power a reconstruction of UK housing stock covering around 18 million dwellings.
The working behind that number sits on Technology.
Nothing about your stock enters the record until you put it there: the first look is built from public records alone.
- A first look, at no cost
The working view of the place you name, built before we meet: which homes come first, and why.
- A working session in HeatAssure
That view, walked through together against a decision in front of you, alongside a sample of your own stock.
- A first piece of work
On one place, small and judged on its own result. The output is yours to keep.
What you keep
- A priority order across the stock, with the reason recorded for each home.
- Cost to target per home.
- The evidence behind both, per home, with its sources.
- A record your board and funder can interrogate.
Your place, as the public record has it.
Name the place and we will show you what the public record already says about it: nothing from your systems, no personal data, no cost to start. We reply within two working days.
