Part Q - Hardware Solutions 

What is Part Q and how does it apply to me as a joinery manufacturer? 

In October 2015 the building regulations were amended for England, through the introduction of Approved Document Q. 

  • It applies to new dwellings, where work started or planning permission was granted after the 1st of October 2015 
  • Regulation applies to doors and windows providing access from the outside 
  • Does not apply to new build hotels or other commercial buildings 
  • Does apply if a building becomes a dwelling through change of use, i.e a barn or warehouse conversion 
  • Does not apply to replacement window and doors


How do I make sure my joinery complies?

There are two ways you can make sure your products comply with Approved Document Q.

  1. Design and manufacture your product in accordance with Appendix B (Doors only).  

Approved Document Q includes an Appendix B giving a pre-determined specification allowing you to build a door set that complies with Approved Document Q.

  2. Manufacture to a design that has been shown by test to meet the security requirements of British Standards publication PAS 24:2016 (Doors and Windows).
