The Vex is a battery-powered sensor that reads the conditions mould needs to grow, warning landlords weeks before it ever appears and keeping their properties compliant with UK housing law.
Inspections run every 6 to 12 months. By the time mould is visible, the health impact, the property damage and the liability are already done.
UK homes are affected by damp or mould, over 9 million rental properties.
Awaab's Law gives social landlords 10 working days to investigate, and 5 to fix.
The cost jump from a £200 early fix to £2k to £10k+ crisis remediation.
Every 20 minutes, each Vex captures temperature, humidity and gas, the signals that precede mould.
A proprietary algorithm turns readings into a live, room-level mould-risk score that sharpens over time.
Tenants get guidance in-app. Landlords see rising-risk units on one dashboard, with timestamped evidence that keeps them compliant with the law and clear of heavy fines.
