What is Document Q and when does it apply?
Approved Document Q is a building regulation which looks at the security of dwellings, ensuring homes are safe and secure.
Building regulations are in place to ensure that minimum standards are adhered to. Document Q ensures that windows and doors and their hardware are resistant to physical attack by a casual or opportunist burglar.
Document Q only relates to NEW dwellings and dwellings which have been converted from their original purpose (i.e. a barn conversion).
For extensions and existing properties there is no legal obligation to meet the Document Q standards. However it is recommended so you can be reassured your doors and windows can withstand a casual attack.
Approved Document Q came into effect in October 2015
Document Q was introduced to help reduce access to potential intruders in new dwellings, aiming to make properties more secure.
Windows which are classed as “easily accessible” within a new build dwelling need to comply with Document Q.
Easily accessible windows are defined as being:
- A window that is within 2m (vertically) of an accessible level surface (e.g. the ground, or balcony),
- A window that is within 2m of a flat or sloping roof (with a pitch of less than 30 degrees) if the roof is within 3.5m of the ground
I.e. windows which could be accessed by an opportunist burglar without a ladder.
Windows will need to resist physical attack by a casual or opportunist burglar.
All door sets providing access into a dwelling from the outside need to comply with Document Q.
With flats, access into the building which contain flats, along with doors leading from a common area into the private flat have to comply with Document Q.
When a garage is connected to the property, with an internal access point into the house, either the garage door or the interconnecting door will need to be Document Q complaint.
Doors and windows will meet the requirements for Document Q if they can resist a physical attack by a casual or opportunist burglar. By being both:
- Sufficiently robust
- Fitted with appropriate hardware.
Doors and windows need to be manufactured to a design that has been tested to meet the security requirements of British standards publication PAS 24:2012/2016.
PAS 24:2012/2016 is a security test for windows and doors. The windows and doors are subjected to timed and specific forms of attack, that are likely to be used by a casual or opportunist burglar.
Front doors (or the door which is going to be used as the main door to enter the property) need to have a door viewer, unless there are other means to see callers before opening the door. E.g. clear glass within the door, or in a window next to the door.
The same door should also have a door chain or door limiter (unless not appropriate).
Where letter plates are used within a door, they should:
- be no larger than 260 mm x 40 mm in size, and
- be located and/or designed to hinder anyone attempting to remove keys with sticks and/or insert their hand through the letter box. E.g. by incorporating a flap or other features to restrict access.
