Indoor Air Quality

Did you know...

81% of people are at risk of suffering from a respiratory or dermatological condition because of poor air quality inside their home.

54% of people have experienced mould or condensation in their home.

15.3 million (65%) homes in the UK are at risk of 'Toxic Home Syndrome'.

Indoor air may contain over 900 chemicals, particles and biological materials with potential harmful health effects.


Poor indoor air quality caused by a build-up of indoor air pollutants can lead to an impact on the health of a building and its occupants.

Most common pollutants are biological such as mould spores, pollen and dander; other pollutants are VOCs, gases, Carbon Monoxide and building materials such as paint containing lead and formaldehyde and asbestos.

Homes have become more airtight in recent years which prevents air from 'changing' (existing air is allowed to escape from a room, new air comes in from outside).

Ventilation levels can be increased in a property by opening trickle vents in windows, clearing air bricks in the walls for background ventilation, installing fans in the bathroom and kitchen unless you have a central extraction unit installed.
