We can tell you which properties will overheat before the next heatwave
From October 2026, excess heat will become part of Awaab's Law, with the same time frames. Rather than wait for tenants to tell you their home is overheating, we can predict which homes are most at risk and alert you up to 14 days before a heatwave.
Same weather. Same problems
This is an anonymised view of a real excess heat report. Switch between the recent heatwave and last summer. The point is not the weather, it is that the same homes keep climbing the list. If you know your most at risk properties, you can prepare before the next warm spell, not scramble during it.
Exposure pattern describes when the heat occurs, from the overnight share of breach hours. It is an indicator to investigate, not a diagnosed cause. 25°C is the Awaab's Law and HHSRS excess heat reference. An exceedance is counted only where 25°C is sustained for at least three consecutive hours, so isolated spikes are excluded. Hours of 35°C or above are dropped first as likely sensor anomalies.
Not just a temperature. A decision
A number on its own does not tell you whether to act. The report turns continuous readings into the three things you actually need before a heatwave: where the greatest risk is, how frequently it is occurring, and how it aligns with legislation.
Ranked by risk, so you can act quickly
Every monitored home, sorted by sustained hours over 25°C and peak temperature, with highest risk at the top. You triage the list and take action in the homes that need it most, rather than waiting for the calls to come in and working backwards.
Sustained breaches, not one-off spikes
A single hot afternoon is not a hazard. The report only counts 25°C where it holds for three hours or more. So you are not chasing the heatwave, and you are not burying your team with false call-outs.
Compliance, not defiance
25°C sustained is the HHSRS reference for excess heat and will be used in Awaab's Law from October 2026. The same investigation timescales as damp and mould will apply, judged against the resident in the home. Action here is defensible evidence if a disrepair claim lands.
The questions you are probably asking
No. The report runs on environmental readings from your existing stock. You find the at-risk homes first, then decide what, if anything, needs doing. Evidence before spend.
No. You get one ranked list of the most severe cases, filtered to sustained breaches. No daily flood of notifications, no surveyors sent out after a single warm afternoon, no exec team chasing noise.
A home is flagged where 25°C holds for at least three consecutive hours, the HHSRS reference for excess heat. Isolated spikes are excluded and freak sensor readings are dropped first, so a flag reflects a sustained, defensible pattern rather than one hot day.
Lead time. We can see which homes have a history of overheating and flag them up to 14 days before a forecast heatwave. That is enough to contact residents, prioritise vulnerable households and act before the temperature climbs, not after the complaints arrive.
From October 2026, excess heat falls under Awaab's Law on the same investigation timescales as damp and mould. A dated record of sustained 25°C breaches, judged against the resident in the home, is defensible evidence if a disrepair claim lands.
Yes. Start with a single scheme over one summer. You will have a ranked picture of where heat concentrates before the next warm spell, with no commitment beyond the pilot.
No. The same sensors that flag excess heat in summer flag damp and mould risk in winter. One estate, the hazards Awaab's Law cares about, ahead of the complaint all year round.
Get ahead of the heat, and the legislation
A heatwave is already forecast and the Phase 2 clock is running. Book a short walkthrough on your own stock and we will show you what the report would flag today, and which homes you would want to look at first.
