       Legislation & Compliance


It is important to comply with all requirements listed in building regulations for installation, inspection, and commissioning when installing fixed ventilations systems in a new or existing property.


Details are highlighted in the UK Building Regulations to ensure a safe air flow in homes and businesses throughout the UK.


Correctly designed ventilation systems will provide rooms throughout a building with comfortable and safe environments to live or work in and also assists the airflow for heating and cooling systems.

Due to the increasing complexity of the regulations, ventilation system design must be considered at the earliest stages of a building project.

The Building Regulations (Part F 2010) considers three ventilation types:

Air Conditioning Ventillation
Whole Building

This type of ventilation provides a constant level of fresh air to dilute and disperse low levels of water vapour and other pollutants, usually by the provision of background ventilators or mechanical supply ventilation.

Local Extract

This type of ventilation in rooms where most water vapour or concentrated pollutants are released, usually by mechanical means such as extract fans.


This type of ventilation for the rapid dilution and removal of high concentrations of pollutants from occasional activities, usually by opening windows. The requirements for Purge ventilation are set out in Appendix B of Part F.

In England and Wales, requirements for ventilation are contained in Approved Document Part F, Ventilation.
