The updated Part F Building Regulations 2022 Documents are effective from 15th June 2022, consisting of two volumes.
- Approved Document F: Volume 1 applies to dwellings
- Approved Document F: Volume 2 applies to buildings other than dwellings
Coastal have covered some of the Frequently Asked Questions in the video below. For further information please consult the Governments Frequently Asked Questions on Part F Regulations Document.
With Part F affecting both new build and existing properties, it’s important to understand what this means for installers and window manufacturers.
As an industry leading hardware provider, Coastal Group have released some guidance on the updated Part F regulations. The below documentation helps educate window manufacturers and installers on why the regulations have been updated, key changes which may affect manufacturing processes and how you can be Part F compliant.
Why Is Ventilation Important?
In recent years buildings have become much more energy efficient, reducing heat loss by improving air tightness. However, this can cause other issues through inadequate ventilation.
Buildings which are poorly ventilated allow a build-up of water vapour which can lead to condensation and subsequently mould growth. Poor ventilation is also less effective in removal of airborne pollutants, having a negative effect on people’s personal health and wellbeing.
The importance of having well ventilated buildings is particularly relevant today, demonstrated by the impact of the airborne virus COVID-19, spreading through the air by droplets that are exhaled by an infected person.
What are Part F Building Regulations? An Overview
The main objective of Part F regulations is to protect the health of occupants of the building by providing adequate ventilation, removing stale indoor air from a property and replacing it with fresh air from outdoors.
Key points of the new Part F 2022 Regulations are summarised below:
- The required level of background ventilation has increased significantly, and multiple trickle vents may be required to meet minimum airflow requirements. This is measured by ‘Equivalent Area’ (AE).
- The Part F 2022 regulations affect both new build and existing properties.
- Application of night vent does not count as a form of background ventilation on the Part F regulations.
- If the existing windows have background ventilators, the replacement windows should include ventilators that are no smaller than background ventilators in the original and be controllable by the occupant.
- The 2010 regulations were dictated by room types, occupancy levels and floor area of the property. The 2022 regulations are simpler and based on a per room amount (follow guidance in table below for reference).
ROOM | Minimum Equivalent Area (EA) For dwellings with multiple floors | Background Ventilators for Single Story Dwellings |
---|---|---|
Habitable Rooms (2/3) | 8,000mm2 | 10,000mm2 |
Kitchen (2/3) | 8,000mm2 | 10,000mm2 |
Utility Room | No minimum | No minimum |
Bathroom (4) | 4,000mm2 | 4,000mm2 |
Sanitary Accommodation (4) | No minimum | No minimum |

How can I be Part F Compliant?
Trickle vents are the most practical and cost-effective method to meet the increase in required background ventilation. Coastal supply a range of trickle vents which have been developed for revisions to Part F regulations.

What are bifold doors and how do I choose the right one for me?
Bifold doors are simply a way of accessing your outside space. So called because they fold multiple times, bifold doors use a concertina mechanism to open and close, folding multiple doors into a smaller space than conventional or hinged doors.
