You have probably heard a lot over the past few months about the incoming revisions to Document Q legislation due to take effect on October 1. You’ve probably also heard conflicting information as to exactly what it entails and what it means for you and your supplier. To make it simple we’ve prepared a simple summary of the most important points.

What is Document Q?

Document Q is an approved government document which specifies the level of security required for doors and windows in new builds. The new update applies only to work started after October 1 2015. Projects with planning permission submitted before October 1 2015 are also exempt providing the work is started on site before October 1 2016.

What does it mean when I’m specifying doors?

Document Q states that “all easily accessible doorsets (including garage doorsets and communal entrance doorsets) that provide access into a dwelling or into a building should be secure doorsets”.

In terms of composite doors, a secure doorset is one that has been tested to meet British Standards PAS 24:2016. As well as having to pass a number of attack tests using various tools PAS 24 compliant doors must also fulfil a number of other design criteria.


Where fitted, letterplates must have an aperture of no more than 250 mm x 40 mm. They should also be located and / or designed to hinder anyone attempting to remove keys with sticks and / or insert their hand. This could include incorporating a flap or other features to restrict access.


The main entrance to a dwelling should provide a means of identifying callers. This could be a door viewer or clear glass in the doorset, or a clear window or sidelight next to the door.

Door Chain or Limiter

Doors should also incorporate a chain or limiter device to help restrict unwanted access.

What are Endurance® Doors doing to comply with Document Q?

At Endurance® Doors our primary concern is that of security. Our door security was already way ahead of what was required for the updated Document Q and we continue to develop our range both in terms of security and style. All of our doors are available fully PAS24 certified.

Anything else I should know?

We’re extremely proud of the quality of our doors. The Metsä Wood Kerto LVL slabs we use in our Endurance® Doors range are easily the strongest, most secure on the market and the doors we build around them are of a similarly high quality. We firmly believe that our doors are the best on the market bar none.
