Air Pollution: Pollution Control
The question
To ask the Secretary of State for Housing, Communities and Local Government, what Government guidance there is on technical standards to be applied in dwellings and other buildings to improve indoor air quality.
Answered by Samantha Dixon
The government sets standards for indoor air quality mainly through Parts F (Ventilation) and L (Conservation of fuel and power) of the Building Regulations which apply primarily to new buildings with detailed guidance provided in Approved Documents. Approved Document F sets minimum ventilation requirements to provide fresh air and reduce risks from pollutants, moisture, condensation and mould. These standards were strengthened in 2021 and took effect in June 2022.
Indoor air quality in existing properties is addressed separately, including through Awaab’s Law which requires social landlords to investigate and remedy damp and mould hazards within set timescales. Government policy is also informed by the Committee on the Medical Effects of Air Pollution (COMEAP) which provides independent advice on air quality and health.
