Part F - Ventilation

Approved Document F

Publication title: Approved Document F - Ventilation (2010 edition incorporating 2010 and 2013 amendments)
Date published: reprinted October 2015


Approved Document F provides guidance on building ventilation, including building air quality and preventing condensation in a domestic or non-domestic structure. 

In a domestic property, ventilation must be circulated continuously throughout the whole building, extract ventilation must be used within an area of increased humidity or pollution, for example an extractor fan over an oven, and purge ventilation must be possible, which is dependent on the area within the premises, but could simply refer to the ability to open a window to air a room out. 

In non-domestic premises, including places of work, priorities include the continuous circulation of clean air, for example with an air conditioning system which can be straightforwardly accessed and refurbished when needed, and minimising the potential risk of any airborne illnesses.
