Evidence the air was cared for.
Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.
When a damp dispute reaches adjudication, the side with the data wins. Envora is the data.
From Awaab's Law to deposit return.
The regulatory ground under UK rented housing has shifted sharply. The Homes (Fitness for Human Habitation) Act 2018, Awaab's Law (2024) and the Renters (Reform) Bill have all raised the bar on indoor air quality, damp and mould — and the evidence landlords are expected to produce when something goes wrong. Social landlords now face statutory response timelines for damp and mould reports. Private landlords and letting agents face the same pressures commercially: tenant complaints, rising insurance premiums, and dispute deposits.
A single Envora One in a flat — typically in the bathroom or the kitchen — produces a continuous, timestamped record of temperature, humidity, CO₂, particulates and the fused IAQ index for the full tenancy. When a complaint arrives, you have the history. When a dispute reaches adjudication, you have evidence. When an insurer asks, you have a log.
For short-let and HMO landlords, Envora also functions as a baseline-check tool: is the unit fresh between guests, is the extractor actually running, is overcrowding tipping CO₂ into stale territory. One pattern dashboard across your portfolio, one alert feed on your phone, one export button for the lawyer.
Six problems that ended at adjudication last year.
The damp-and-mould dispute
Tenant says mould. Landlord says lifestyle. Without continuous humidity and IAQ data, it is a he-said-she-said. With Envora, the record shows exactly when and why the humidity climbed — and whether the extractor fan ever ran.
Awaab's Law compliance
The 2024 legislation imposes strict timelines on damp and mould response for social landlords. Envora is the continuous-monitoring evidence that you identified, recorded and responded inside the window.
HMO overcrowding signals
CO₂ climbing past 1,800 ppm in a shared bedroom is a quiet proxy for overcrowding. Envora flags it before a neighbour complaint or a council visit.
Insurance and inventory
Moisture and mould are among the most common buildings-insurance claim categories. A continuous log demonstrates reasonable care — and often reduces comprehensive.
Void-period drift
Empty flats with heating off can drift into mould-risk humidity over winter. Envora alerts you during voids so the next tenancy does not begin with a problem.
Short-let quality signal
For Airbnb-style operators, proving the unit was fresh at check-in is part of the product. Envora produces a shareable reading for each turnover.

What unmonitored air quietly puts you on the hook for.
Mould & damp risk
Mould does not appear from nowhere. It is the visible end of months of sustained humidity your house has been trying to tell you about.

A CO alarm chirps at 35 ppm. Your nervous system reacts at 1. Envora watches the band that does not set anything off — but accumulates anyway.
Read the guideCooking pollution
Frying on a gas hob can push PM2.5 past a London roadside reading in six minutes. Most domestic extractors were never designed for it.
