One platform for damp & mould, legionella, retrofit and assisted living. Reads your housing stock continuously. Writes the evidence record before the regulator asks.

These are the exact problems - in housing teams' own words - that shaped every COSIE feature.
"By the time damp and mould is reported, it's often harder to fix, and harder to evidence you had it under control."
COSIE monitors continuously and scores a damp‑ and mould‑risk per property - evidence is there before the complaint lands.

Continuous temperature on flow and return means 365 days of evidence, not one. ACOP L8 compliance, automated.
See legionella →"You've invested in retrofit. But can you actually prove it's working, and that it hasn't created new risks?"
Measure the home before and after. Attribute performance to the fabric, not the resident. Monthly PAS 2035 reporting, automated.
See efficient homes →"Falls don't announce themselves. By the time someone finds out, the golden hour has passed."
DORIS care detects changes in activity without cameras, microphones or pendants - and transmits every 4 hours.
See DORIS care →Your damp team, your water team, your retrofit team - all see the same stock through the same lens. Install once. Evidence forever.
One cellular device per property. Remove the plastic tab, 3M-stick to the wall - live in 5 seconds. No hub, no gateway, no Wi-Fi. Hourly data points, daily upload. Our proprietary damp & mould-risk algorithm predicts the problem before it shows, with root-cause attribution across Excess Moisture, Under Heated and Under Ventilated.
A Legionella Hub with two clamp-on sensors on the flow and return pipes. Non-invasive - no plumber, no downtime. Samples every two minutes. 365 days of continuous temperature evidence, not a single inspection-day reading.
Adds a Boiler Hub and clamp-on boiler sensors to the base COSIE device. Captures fabric response, heating delivery and comfort. Monthly PAS 2035 reporting shows exactly how the investment performed - in the home, not just on paper.

We wanted actual data to support that indoor air quality and the way the home is heated has genuinely improved. The sensors that are already in properties are providing live, continuous data to evidence the retrofit improvements we are making.

Practical intelligence from teams managing real housing stock - not theory, not vendor spin.
The enforcement date has passed. We've documented the exact evidence trail that satisfies the regulator - and how COSIE generates it automatically.
How a Kent-based housing association transformed their damp and mould response in under three months - and what their housing officers say about it now.
Large-scale retrofit programmes create new risks alongside the energy savings. Here's what continuous monitoring tells you that an EPC won't.
Try five COSIE units in five of your homes. After 30 days, you'll see the evidence record you'd have had if the damp report arrived tomorrow.
