Home Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free. Office & Co-work CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with. CO₂ and indoor air quality monitoring for schools Classroom CO₂ and indoor air quality evidence for better ventilation decisions, measurable cognitive lift, and the data trail governors and parents want. Labs & Clinics Envora One is precise enough for laboratories, clinics and regulated spaces, and comes with a signed calibration certificate per device ID. Studios & Gyms Hot yoga, spin, HIIT and small studios generate extreme humidity and CO₂ loads. Envora tells you how your ventilation is holding up — live, per-room, per-class. Podcasts & Studios Envora flags the HVAC hum, the fridge compressor, the neighbour's drill — and the concentration drift that flattens your delivery — before the tape picks any of it up. Landlords & Letting Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.

Damp and mould dispute evidence

A damp dispute typically devolves into landlord-says-it-is-occupancy versus tenant-says-it-is-the-property. Continuous environmental data settles the question in days rather than months.

Why disputes drag on

Most damp and mould disputes lack continuous data. The landlord inspects when the tenant complains and finds 60% RH at 11 AM on a sunny Tuesday. The tenant insists the bathroom is at 95% RH every morning. Without data, this becomes a he-said/she-said argument that ends up at the ombudsman or in court.

Continuous monitoring captures: bathroom RH for every hour of every day; the CO₂ rise overnight in the bedroom (a strong ventilation signal); the kitchen humidity recovery curve after cooking. A month of this data ends the dispute.

What the data typically shows

From cases we have seen, the pattern is roughly:

- 40% structural — the property has insufficient extraction or insulation; mould would appear regardless of how the tenant lives.
- 40% mixed — the property is borderline, and tenant behaviour (drying laundry indoors, never opening windows) tips it into mould-risk.
- 20% behavioural — the property is fine; the tenant is producing far more humidity than typical (often 5+ adults in a 1-bedroom flat) and not ventilating.

The data makes which is which obvious within 14 days.

Using Envora data in a dispute

Envora Fleet provides CSV export with timestamped readings for every channel, plus a signed audit log of when devices were installed, when they were rebooted and when readings dropped. This combination has been accepted as supporting evidence by:

- The Housing Ombudsman (social landlord disputes)
- The First-tier Tribunal Property Chamber
- Building insurance assessors
- Damp specialists conducting follow-up investigations

For social landlords specifically, the continuous record materially supports Awaab's Law compliance — statutory deadlines become trivial when the underlying data has been continuously logged.

FAQ

FAQ — Damp and mould dispute evidence

Is Envora data accepted as evidence?

Yes — by the Housing Ombudsman, First-tier Tribunal, building insurers, and most damp specialists. The signed audit log of device installation and reading continuity is the key element.

Can the tenant tamper with the data?

No. Readings are signed at the device, transmitted over TLS, and the audit log records any device-level events (reboot, power loss, time changes). The data record cannot be retroactively altered.

What about tenant privacy?

Envora One measures environmental conditions only — no occupancy patterns, no audio frames. The sound channel reports a single dBA number (environmental noise), not recordings. Tenants should be informed and any tenancy clause should be clear about what is monitored.

How does Awaab's Law factor in?

Awaab's Law (in force October 2025 for social landlords in England) sets statutory deadlines for investigating and responding to damp and mould reports. Continuous environmental data is the cleanest possible way to meet those deadlines.
